The present application claims the priority of provisional patent application U.S. serial number 60/067228, filed December 2, 1997 in the U.S. patent office, which is included herein by reference.

The technical field to which the invention relates.

The present invention relates to protective devices and, in particular, to a protective device or element having a large number of security features for use with valuable goods or objects.

The level of technology

Forgery or attempted forgery-protected documents or securities, such as banknotes, cheques, tickets, credit cards, etc. and other valuable goods or items is a common problem in many areas or businesses. To prevent forgery, many protected documents and other valuable items contain protective device, or item, such as a security thread, located on the document or inside it. Protective device generally includes one or more protective elements, for example metal protective signs, magnetic protective signs or fluorescent security features that certify the authenticity of the document and prevent forgery or attempted forgery.

To establish the authenticity of the document, many of the normal protective devices simply require is yavleniya availability of only one protective characteristic. Thus, poddelyvali for forgery is only required to identify protective sign the document or object and play this one protective characteristic in the forged document or subject to this protective trait could be identified to establish the authenticity of the forged document. Advances in technology have led even to a new and simpler ways to identify these protective characteristics and reproduction of valuable documents or instruments payable to bearer with protective devices. Thus, there is a need for more hidden protective characteristics that are not easily identified and reproduced.

One type of protective thread contains metal signs, such as metal graphic signs located on the carrier substrate. In accordance with the usual methods of chemical etching on the metal layer is applied by printing chemical resist in the form of a graphic character or positive, or negative, and remove the metal areas of the metal layer not covered with the resist chemical that causes the formation of graphic signs, negative or positive, the remaining metal layer. Security threads having only protective metal sign, formed in accordance with this method, do not provide adequate protection due to the fact that the forger mo is no easy to discover and play metal graphic characters.

Attempts have been made to combine a lot of security features, such as metallic and magnetic signs to make forgery more difficult. In one example using a magnetic paint for application by printing graphic characters that can be read by the detectors IDs of characters from the magnetic paint (ISMC). However, if you use magnetic ink for printing graphic characters on a metal protective signs or protective metal signs, magnetic signs and metal signs are easily detected and identified. The forger may determine that were used as magnetic and protective metal signs, and they need to reproduce.

In other types of protective threads were also used hybrid metals or alloys for the formation of graphic characters with magnetic and protective metal signs. However, hybrid metals and the deposition method or the application of hybrid metal for forming the graphic signs are expensive. The use of hybrid metals also restricts the ability to modify the magnetic properties, which can be used.

In accordance with the above there is a need for a protective device that has a lot of security features, such as metal and MAGN is the shaft of protective signs, which are not easily detectable and recognizable when considering protective device. There is also a need for a protective device in which a protective sign (signs) are able to provide the coded data read by the machine, for example, related to a protective device or document, in addition to detecting signs to authenticate the protected document. You also need a method of manufacturing a magnetic/metallic protective device that uses existing technology chemical etching and removal of metals.

A detailed description of the preferred alternative implementation of the present invention

The protective device 10 of figure 1, corresponding to the present invention, is used with the object 12 to prevent forgery or reproduction of the object 12 or the articles attached to the subject 12. Protective device 10 has a large number of security features, such as metal protective signs and magnetic protective signs, capable of encoding data in a format readable by machine, in addition to providing authentication of the subject 12. Metal and magnetic security features preferably are formed using magnetic chemical resist, as will be described in more detail below, in such a way that at least some of the metallic and magnetic protective signs usually fully combined one with another and, in fact, not visible to the naked eye.

Protective device 10 can be used not only in such protected documents as banknotes, currency, passports, visas, property rights, licenses, papers the registration, checks, money orders, origins, powers of attorney, tickets and gift cards. Protective device 10 provides authentication of the secure document and/or encoded data related to a protected document or to the protective device.

Protective device 10 can also be used in labels, tags or packaging material containing, but not limited to, labels, pressure sensitive, adhesive labels, pressed labels, labels, heat shrink, woven label, torn tape, usively caps and ribbons and stickers. In this example, the magnetic/metallic security device 10 verifies the authenticity and/or coded data relating to the items to which is attached labels or packaging material, such as alcoholic beverages or other valuable goods.

Protective device 10 can also be used with multi-layered product, such as, but not limited to, passports, identity cards, permits, licenses, and credit/debit card. In this example, the protective device 10 is used to establish the authenticity of the layered products and/or encoded data related to the product or to the owner of the product.

Protective device 10 can also be used in the tickets or passes, including t is such as, but not only, tickets to sporting events, transit tickets, lottery tickets and entry passes. According to this example, the protective device 10 can provide authentication of the ticket or pass and/or may be encoded with data related to a specific event. The present invention also discusses other uses and applications for the protective device 10 to ensure protection against falsification, reproduction, or other secure valuable items or products.

According to a variant implementation, the clerk of example, the protective device 10 is formed in the form of strands or strips located partially or completely along the object 12 in any direction. Protective device 10 can be deepened in item 12, is attached to the object 12, is woven into the subject 12, or located in a layer between the many layers of the object 12. The object 12 may also contain a number of protective device 10 in accordance with the present invention.

The protective device 10 of figure 2 includes a carrier substrate 14, for example, formed in the form of strands or strips. One type of carrier substrate 14 is made of polyester, polyvinylcarbazole or propylene, is applied in the form of a film on paper. Alternatively the carrier substrate 14 may be of plastics is the first film, or metallized paper, or another type of material used in conventional protective threads.

In the embodiment used as an example, the protective device 10 includes a graphic signs 16, formed of metallic/magnetic environment, located on the carrier substrate 14. Graphic symbol 16 can be positively formed on the carrier substrate 14, i.e. graphic symbol 16 consists of a magnetic/metallic environment. Graphic symbol 16 can also be made the opposite way, i.e. the area 18 surrounding the graphic symbol 16, consists of a magnetic/metallic environment. Magnetic/metallic security device 10 can also be formed as a combination of positive and reverse graphic character 16. Graphic marks 16 may be printed in the form of lines, in which the solid parts are printed in the required form, or in the form of tones, in which small dots are printed with different intervals between them to change colors. Although graphic marks 16 are shown as alphanumeric characters, the present invention provides any type of symbol, pattern, shape, or other graphic characters.

A method of manufacturing the protective device 10 to Figa and 3B, the employee example, in accordance with the present invention includes the initial application of the metal which CSOs layer 20 on the carrier substrate 14. The metal layer 20 preferably contains aluminum, which was deposited by cathode sputtering or vapor deposition on the carrier substrate 14. The metal layer 20 may be a metal foil or a metal of a different type, deposited on the carrier substrate 14.

Then on the metal layer 20 is applied to the magnetic chemical resist 22 in accordance with the desired configuration of graphic characters 16, for example, printed a positive, reverse or in combination. Magnetic chemical resist 22 contains chemically resistant film-forming resin comprising ferromagnetic and/or other magnetic pigments. Examples of chemical resist include, but are not limited to, resists, solvent-based, water-based or solids-based, ultraviolet (UV) or electron beam (E) polymerized resin or other conventional chemical-resistant resin. Magnetic pigments contain both hard magnetic and soft magnetic pigments, as will be described in more detail below, the magnetic field strength in the range of from about 200 to 10000 E.

Then carry out a method of etching a magnetic/metallic protective device 10 to Figv to remove sections of the metal layer 20, which is not protected by the magnetic chemical resist 22. The etching method includes the usual the operation of chemical etching, well-known experts in this field. Magnetic chemical resist 22 resists chemical attack and remains located underneath the metal layer 20, the magnetic chemical resist is in the form of a given printed configuration. Magnetic chemical resist 22 on the metal layer 20 is substantially the same combination of at least one section of the metal layer, thereby providing magnetic and metal protective characteristics that are essentially indistinguishable, at least in some parts of the protective device 10. Magnetic chemical resist 22 thus, as opposed to chemical attack during the etching of the metal layer 20, and provides a magnetic protective sign, located on the protective metal sign so that it was not easily identifiable.

Graphic marks 16 can also be formed using other technical means, including, but not limited to, lasers, mechanical scribing, striping, etc. In one example, over a substrate comprising a metal layer, is applied to the magnetic layer and give it a method of laser etching. Laser etching selectively removes the magnetic metal layer and forms required design marks 16, having communicated to the private protective sign, located essentially the same over the metal protective trait.

The present invention also provides the use of an additional coating or film 24 (see Figs) on top of the graphic marks 16 on one or both surfaces. In one example uses an additional layer 24, which helps to hide the protective device 10 when it is embedded in the paper and examined under reflected light. In this case, however, design marks 16 created using magnetic chemical resist, will remain visible when seen by transmitted light.

Protective device 10 on Figa and 4B can be encoded analog or digital data that is read by the machine, and to provide authentication in different ways, using different properties of metallic and magnetic shielding characteristics. The use of one or more metallic and/or magnetic properties for authentication of the protective device 10 or item 12 includes the determination of whether there is or not one or more properties in the protective device 10. The use of one or more metallic and/or magnetic properties to encode analog or digital data includes the detection and reading of the combination of properties that represent the number of the th code, for example, in a binary coded decimal (DDC) format and decoding code data definition, prisoners in it.

Magnetic shielding characteristic can verify the authenticity of an object or to encode data relating to the object, in a variety of ways. In one example, design marks 16 are formed as magnetic characters that can be read by normal ISMC detectors. In this example, design marks 16 are preferably formed as a positive text.

In accordance with another example of the magnetic chemical resist 22 contains a hard magnetic pigment, which is able to be magnetized in the same manner as film for magnetic recording. In this example, design marks 16 on Figa preferably formed as reverse the text so that the magnetic chemical resist 22 containing hard magnetic pigment, forms one or more magnetic tracks 23a, 23C. Identifying the data or other information may be recorded on the magnetic track (tracks) 23a, 23C and read from them using conventional recording devices and normal readers.

In accordance with another example of the magnetic chemical resist 22 contains a soft magnetic material that can be magnetized and to maintain the level of magnetism within a limited period BP is like depending on the characteristics or properties of soft magnetic substance. The use of soft magnetic substance also allows you to hide the magnetic shielding characteristic due to the fact that the magnetic properties will not be detected until soft magnetic substance will not be initially magnetized. Soft magnetic substances usually have some magnetic characteristics such as the level of magnetism that they can achieve, and the decay rate of the magnetic charge. Soft magnetic substance can be used to provide identity authentication through the initial magnetization of the magnetic/metallic protective device 10 and the subsequent detection of the presence of a magnetic substance, i.e. the level of magnetism or the rate of decay.

Giving a soft magnetic substances of different magnetic characteristics, for example different levels of magnetism, which can be achieved, or the rate of its decay, design marks 16 on FIGU can also be used to encode data in a format readable by the machine. For example, the segments 16A-16d graphic characters can contain two types of magnetic pigments, one that has a fast decay rate 28a, and one with a slow decay rate 28b, which are binary integers to encode data in the DCD format. Some segments 16A, 16C graphic characters printed in magnetic the substances, with a slow decay rate. The data thus encoded in the DCD format (0101) by providing a specific configuration of the segments 16A-16d, having two different types of magnetic pigments. The coded data may contain data for audit or other data relating to the object 12.

In accordance with one method of the present invention in a metal layer 20 type different compositions of the magnetic chemical resist 22 having magnetic pigments with different magnetic properties or characteristics, using the various settings for printing, such as offset printing press similar to that used for multicolor printing. Use different settings for printing allows you to print graphic characters of any desired configuration using different combinations of the magnetic chemical resists having different magnetic properties.

The present invention also provides for the simultaneous use of characteristics such as the level of magnetism and the decay rate of the magnetic substances, and a mixture of hard magnetic and soft magnetic substances to achieve any desired combination of magnetic characteristics or properties to establish the authenticity of the product or encoding data relating to the sight of the etu. Although a sample implementation described above, refers to two different magnetic properties to encode data in the DCD format, any number of different properties can be used to encode data in other numeric formats. In addition to authentication and encryption of data using magnetic protective characteristics protective metal sign can also provide authentication and/or encryption of data, for example, by forming the segments 16a-16d different lengths of metal, representing the data in the DDC format (1100), as will be described in more detail below.

The device 30 according to Figure 5, used for reading the magnetic/metallic security features comprises at least one detector/reader 34 for detecting one or more characteristics of metallic and/or magnetic layers, and/or to read a specific configuration, formed of metal and magnetic fields with different characteristics. After detecting one or more characteristics of the determinant of authenticity 36 determines whether the protective device is authentic. After reading the specific configuration of the decoder 38 decodes the data represent a specific configuration.

When the protective device 10 includes a magnetic protect the local signs, having a soft magnetic substance, the device 30 also includes a magnetic charger 32 charges the soft magnetic pigments before the reader 34, the detecting characteristics of the magnetic substances, such as magnetic substances, the level of magnetization, the decay rate of the magnetism of the magnetic material, or other detectable magnetic characteristics. Authentication can be performed based on whether the soft magnetic substance, whether soft magnetic substance a certain level of magnetization, or whether soft magnetic substance specific decay rate.

Decoding is performed by determining the configuration of different magnetic characteristics, is read by the reader 34. For example, if the magnetic/metallic security device 10, shown in Figure 4, the part is subjected to application of magnetizing device 32, after some period of time segments 16B, 16d, with a slower decay rate 28V, will remain magnetized, and the segments 16A, 16C, with a faster decay rate 28a will no longer magnetized. The reader 34 distinguishes different magnetic properties and defines a particular configuration of the magnetic properties. Based on the specific configuration of the magnetic properties are decoded corresponding binary representation is of (0101) and the data they represented.

Protective metal sign 40 6 in accordance with one embodiment of the present invention contains a large number of electrically conductive areas 42 and non-conductive regions 44, such as metallized polyester film having periods without metal, for example, formed using a method with a chemical resist described above. Each non-conductive area 44 is located between the two conductive regions 42. A large number of conductive areas 42 and non-conductive areas 44 form a specific configuration, which is a code for checking or data encoded protective metal sign 40.

Each conductive region 42 has one of at least two specific lengths, for example the long conductive region 42A and short conductive region 42. Each defined length corresponds to a particular value so that the data can be determined by detecting the length of each conductive region 42 and determine the corresponding value.

In one example, the long conductive region 42A correspond to “1” and short conductive region 42 correspond to “0”. In accordance with this example long and short conductive area 42 a and 42 used throughout the world is to encode data in the DCD format. Long and short conductive area 42 a, 42 are located in certain series, corresponding to the binary coded data. In this example, the detector/reader 34 detects the length of each conductive region 42 in series (for example, long and short) and determines the appropriate binary representation. To provide authentication, the binary representation should coordinate with a specific code validation for subject 12. To read the coded data, the binary representation should be decoded.

According to this, depending on the location of the conductive regions 42 having different lengths, a virtually unlimited number of codes validation or data may be encoded using a metal protective characteristic 40 read by the machine. Read machine protective metal sign 40 in accordance with the present invention allows to easily change the coded data by changing the sequence of electrically conductive areas 42 a, 42. Conductive region can be formed in accordance with various methods, provided that they are electrically conductive in one certain length, as will be described in more detail below. Although, for simplicity, will be reviewed here only two lengths, this is the invention involves the use of conductive regions with any number of different lengths for encoding data. For example, the octal data can be encoded using eight (8) of electrically conductive regions of different lengths.

One way to read and verify protective metal sign 40 Fig.7. a machine reading is the detection of long and short conductive regions 42 a, 42, with capacitive test or detection of, for example, disclosed in U.S. patent No. 5419424 issued by Harbaugh (Harbaugh) and is given here as a reference. In accordance with the methods of the capacitive test machine readable protective metal sign 40 is located next to the capacitive sensitive elements 50 connected to the test device (not shown). When capacitive sensitive elements 50 are located near the conductive regions 42, conductive region 42 provide capacitive coupling of one sensor element 52a with another sensor element V. Where there is non-conductive region 44 or “gap” in conductivity will not be capacitive coupling between adjacent capacitive sensors V, s on each side of the non-conductive region 44. Detection of changes in capacitance effectively revealed the presence of long and short conductive regions 42 a, 42 when the machine readable coded protective metal sign 40 located the Yong next to the capacitive sensitive elements 50. The present invention also addresses other devices and methods for testing, can determine the length of the conductive regions 42 a, 42, for example, various electromagnetic devices for testing.

Conductive region 42 machine readable coded metal protective characteristic 40 is mainly formed from a metal material such as aluminum. Methods as examples include, but are not limited to, the formation of the conductive regions 42 through metallization polyester film, hot stamping foil and printing of conductive areas 42 of the metallic paint. The present invention provides for other types of metallic material and methods of forming the metal conductive areas and non-conductive gaps between them.

Read machine coded protective metal sign 40 and the protective device 10, in which it is used, primarily intended to ensure minimal “extension”, for example, to approximately 5%or less change in length. Also the determination of the lengths of the conductive regions 42 a, 42 must explain the possible stretching of the protective device and machine readable coded metal protective characteristic 40, for example, about Yasnaya possible percentage change in length.

In accordance with another embodiment of the present invention encoded protective metal sign with machine reading 40A on Fig has a conductive area 42 a, 42, each of which contains a character 46. Sign 46, printed or located on the conductive regions 42 a, 42 may be used to provide additional validation code or data, or can be used to provide false configurations that deceive poddelyvali and hide this validation code. Such characters include alphanumeric characters 46a, bar codes V and other images s. Marks 46a-C in accordance with this embodiment is applied by printing or placed on electrically conductive regions 42 a, 42, without interrupting the conductivity of each conductive area 42 a, 42, and without affecting the capacitive determining the length of each conductive area 42 a, 42 using capacitive sensing elements 52.

In accordance with another embodiment of the encoded metal protective characteristic 40V with machine reading on Fig.9 conductive region 42 is formed as a conductive region marks a-z of electrically conductive material, such as printed with metallic inks or formed by the method of application of chemical resist. Conductive marks a, s are created so that individual characters or symbols 49a-49f characters are connected at the contact points 48 between them and separated by non-conductive regions 44. Conductive marks a-s, thus, have different lengths and are arranged in certain configurations, representing coded data, which are decoded as described above. Conductive marks a-C include alphanumeric characters and other symbols or characters used to provide additional validation code or to provide false configurations that cheat forger and hide the real coded data.

Another variant implementation of the encoded metal protective characteristic 40s with machine reading on Figure 10 in accordance with the present invention contains conductive region 42A-42s, for example a narrow region of metal material, and a non-conductive region marks 64A-C, interrupting the electrical conductivity between the electrically conductive regions 42A-42s. For example, can be formed in certain alphanumeric symbols or other signs of non-conducting material or by using a method with a chemical resist and removing the metal between the conductive regions 42A-42s to provide “gap” electrop the water. Alphanumeric characters or other characters forming marks 64A-C also provide additional data or codes and false configuration that fool forger and hide the real coded data.

The present invention involves the use of magnetic shielding characteristics and protective metal signs separately or together in a protective device. Any number of magnetic or metallic properties described above can be used individually or in combination with other properties to ensure the authentication of the subject, encoding data relating to the object, or both.

In accordance with the variations in implementation of the present invention, one or more protective devices or threads 10 and 11 may be provided at different sites or embedded in the protected document or bearer instrument 70. One or more protective devices 10 are read in different directions, and with the correct side or on the reverse side. In one example, a secure bearer instrument 70 is formed by bonding the protective device 10 between two lightweight pieces of paper, which are then laminated. In this example, the protective device 10 mainly not susceptible to delamination, p is that any attempt to stratify securities 70 and remove the protective device 10 will result in what glue holding together a paper laminate, remove metallic and/or magnetic security features and change the protective trait or encoded data.

One example of a bearer instrument 70 is the ticket used to visit sporting events, concerts, theatres, exhibitions, lotteries, vehicles, theme parks, fairs and other Protective device 10 in the ticket can be encoded in a certain code for authentication or data that can be read at the presentation of the protected paper 10, such as admission to an event. In one example, one complete code 72 appears on the segment of length 2.5 inches.

Under this protective device in accordance with the present invention establishes the identity of the subject and/or coded data relating to the object, in a variety of ways with one or more protective elements, such as metal protective signs and magnetic security features, which usually occur together as one protective characteristic. Protective signs and coded data, thus, more difficult to identify and reproduce. A method of manufacturing a protective device using chemical etching and magnetic chemical resist provides magnetic shielding characteristic that, by beings who, no different from the metal of the protective trait. The method of printing graphic characters using magnetic chemical resist also facilitates the use of magnetic pigments having different magnetic characteristics or properties, for application by printing different formulations of the magnetic chemical resist.
