Prior art
There is a method of inputting a graphical password in which to enter the password the user must in a certain sequence to touch areas of the graphics image on the display with the mouse (U.S. patent No. 5559961, IPC G06F 11/00, publ. 24.09.1996).
However, the degree of protection of the password will not be high. First, any user can see the process of data entry of the password and is able to repeat it. Secondly, the number of possible combinations generated passwords are not high and easily selected. In addition to the lack of a high degree of user protection, there is one significant disadvantage - not every user-selected password is easy to remember. For access to many databases need to be stored in memory number of different combinations of passwords that an abundance of such systems becomes impossible.
There is also known a method of password, which is used changing the graphic image in the form of digits for a password, the user carries out a logical operation, such as subtraction, displayed above, and is conceived images of digits (Pat the NT Japan No. 6-214954, IPC G06F 15/00, 3/02, publ. 05.08.1944).

figure 2 - illustration of a second variant of the method of the password using images with dynamically changing content displayed on the display of the user computer;
figa-d - a detailed view of atapo the input password according to the second variant embodiment of the invention.
Preferred embodiments of the inventions
In accordance with the first embodiment of the claimed method (figure 1), the user first determines the number of screens, the type of images displayed on each of the screens, the number of objects displayed in each screen, and the order in which you want to choose the objects of the dynamic image, and on which screen. In addition, the user determines how the contact means (for example, the left or the right mouse button or a specific button on the keyboard and so on) will mark the time of occurrence of a particular screen or other pre-defined object. A predefined object of the dynamic image is an object, who conceived the user's position in space and/or who conceived the user state in time.
Additionally, the user can determine which screens are meaningful for a password, and which of them are insignificant, i.e. will be used to improve the secrecy of the password. Appropriate settings of the user are recorded by the software.
According to figure 1, the user is prompted to follow the appearance of them on the specified number of screens (in this case four) volume graphics is tov, pre-defined to create a password. The points in time when each of the screens appears, if a user-defined object, there are selected contact means, for example by clicking with the left mouse button or by pressing the selected button of the keyboard. The content of each screen may be changed any number of times by the user and the selected speed. For example, the number of images displayed periodically every screen is 20. The password can be defined by the user, for example: the appearance of a tiger on the top right of the screen; the appearance of the parrot on the left bottom of the screen; the appearance of sharks on the top left of the screen; the emergence of a butterfly on the lower right of the screen. That is, the first stamp of the time, made the selected contact means, addressed to the right top of the screen, the second lower left of the screen, the third is the upper left, the fourth lower-right, that must match the pre-specified by user selection order of the objects on the respective screens. The feature of password is that when fixing the time of occurrence of a predetermined object displayed when the process continues until all objects entering the password. In the display process of the password does not detect that the poet is an observer does not know with the advent of the object and on which screen keeps the user, i.e. the appearance of any object on any of the screens and in what order the notes user.
Function save parameters dynamic image serving for a password, the comparison referred to the saved settings with parameters of the marked objects of the dynamic image and if it matches the specified parameters, to identify the password are implemented using appropriate software.
There are various options for implementing a process of entering the password. First, the choice of the objects of the password in each of the screens is not mandatory, i.e. the user when determining the number of screens for display can be set as any significant number, for example three. In this case, the password consists of any three objects of the dynamic image. Secondly, to mark the points in time of the occurrence of each of the objects you can select a specific contact means. In this case, the example described above with reference to figure 1 will look like this. If the user password matches the appearance of a tiger on the upper right screen, the appearance of the parrot on the left bottom of the screen, the appearance of sharks on the top left of the screen and the emergence of a butterfly on the lower right of the screen, the time p is the phenomenon of the tiger, the user may mark the left mouse button, when a parrot is right, the shark left, butterfly - left. Thus, the user chooses the degree of secrecy of your password and level of complexity of its memory. Thirdly, when defining a password, you can choose the contact means insignificant to create a password. That is, in the above password right mouse button is considered to be insignificant, therefore, pressing the button does not affect the password. This further increases the degree of protection of the password from the observer - now not only that an observer does not know, with the advent of the object and on which screen keeps the user, he also does not know whether the appearance of this object is meaningful for the password, i.e. whether the involvement of a specific contact is meaningful to you for a password.
In another embodiment, illustrated using figure 2, the user is prompted to follow the selected objects, merged into a dynamic (animated) image. According to figure 2 such objects presented on the displayed image, as a child, ball, fish, butterfly change their position in space, and such an object, as a bird changes its state, i.e. flies, without changing their coordinates. The points in time when animated objects occupy a predetermined position in space and the and reach a certain state in time, marked by the user in any chosen for this device to mark points in time (e.g., by mouse click or by pressing the selected button of the keyboard). The user password can match the States of the animated objects in the moments of time when the fish went under the water head (figa), when the child still stood at a ball (FIVB)when the ball appeared on the screen (pigv)when the butterfly is on the extreme right umbrella (high) and when the bird raises his wings up (figd). That is, the first mark of time, for example, the first mouse click, addressed to the fish, the second child, the third ball, the fourth butterfly, fifth - bird, that must match the pre-specified by user selection order of animated objects.
The feature of password is that when fixing the time of occurrence of a predetermined object in a predefined point in space or achieve the object of a predetermined condition, the process of displaying animated objects continues until the full password. In the display process of the password does not detect, so the observer does not know the position in space and/or the state of any object is monitored by the user, and in what order the user notes. If e is ω displaying animated objects the user-set animation speed periodically repeated in time in case if the user does not have time to mark the object in a predefined position. Possible all of the above features create a password: select all animated objects password on a dynamic image is not mandatory, i.e. the user when defining objects for a password may declare any significant objects.
Functions such as mode selection state changes of each of the screens, the determination of the rate of change in state of each of the screens, the definition of the speed of the animation of the objects of the dynamic image, the order of selection of objects dynamic images on the respective screens of the account entered by the user indicate which of the activated contact means are significant for a password, are implemented using appropriate software.
When entering the password, representing a rhythmic sequence, the user must enter a predefined rhythmic sequence with predefined contact means. The rhythmic sequence can be selected piece of music, and the contact means can be assigned to function keys of a musical instrument.
For example, as a means to enter is the password the user selects the left and right mouse buttons. The user password can be specified as follows: three pressing the left mouse button, double tap the right mouse button, three right, two left, three right, one left, one right, one left, one right, two left. This, at first glance, it is difficult to remember the password, is a melody known as "Dog waltz", played on two keys of the keyboard instrument. This password is not easy to look at and to repeat, because the hand completely covers the mouse, fingers are constantly on both the contact means is difficult to determine which mouse button is pressed and how many times. Only the user knows the key of the melody, which can store the password in the corresponding rhythmic sequence and the number and sequence of zadeistvovany each of the selected contact means. When you create a password as a contact means for a password, the user can select any funds from a group that includes the keyboard, mouse buttons, combinations thereof, and the aggregate of the contact means with identical functions. For example, to enter the above password the user chooses the top row of the keyboard, which shows numbers instead of the left mouse button, and the right margin of the keyboard, where are the numbers, instead of the right mouse button. In the process a password within each group of buttons, each of them identical in meaning. I.e. no matter what the group buttons is pressed, it is important to any group, "right" or "left", she belongs to. This method of password increases the degree of protection against outside observer because the observer is not only "hears" entered by the user rhythmic sequence, but does not know what the meaning of the contact means corresponds to each code element. The code in the form of a rhythmic sequence can contain any number of "sounds", i.e. pressing contact means, depending on the ability of the user to his memory.
Entered by the user rhythmic sequence is compared with the previously stored rhythmic sequence and when coincidence occurs for password authentication. These functions can be implemented using software.
In one embodiment, a rhythmic sequence can be introduced in the form of a set of long and short zadeistvovany predefined user contact.
The process of entering the password in a rhythmic sequence is not accompanied by the display of any images on the screen, and access to a computer database does not occur until the full password.
Advantages of password using dynamic images are: b lsoe the number of possible combinations - each animated object can accept a sufficient number of catchy provisions, as well as a high degree of protection from the observer or the attacker, which can be implemented in any of the above means, or a combination. Thus, the proposed method password helps to solve some of the major challenges faced by the user when selecting, storing and protecting your password to access computer databases.
Advantages of password using rhythmic sequences are: a large number of combinations generated on the basis of known melodies and rhythms, provide simplicity and ease of remembering the password by the user; the input method rhythmic sequences additionally provide a high degree of protection against third-party observer.
