Import control of content. RU patent 2324301.

FIELD: information management systems.

SUBSTANCE: method for controlling import of content into a domain comprising number of devices consists in checking for the presence of a domain watermark in the content, and if the domain watermark is found in the content, refusing import of the content into the domain, and if the domain watermark is not found in the content, allowing import of the content into the domain and causing the domain watermark to be embedded into the content. Optionally, re-importing into the "original" domain might be allowed. The method further comprises refusing import of the content into the domain if the domain watermark is found in the content unless the identifier matches an identifier for the domain. Other payloads in the domain watermark can be used to e.g. implement location- or time-based restrictions on import.

EFFECT: providing a method for discerning the input of legitimate unencrypted content from illegally copied unencrypted content.

Method for storing pages in memory of mobile device (variants) and mobile device for realization of the method / 2316131
In accordance to the invention, mobile phone, having additional module, realized on SIM-card of mobile phone in form of internal browser with internal site. When a user wishes to access a page, such as an Internet-page, using his mobile phone, internal browser browses first file on internal site, to find page identifier and to determine whether it is possible to access that page immediately. If so, then internal browser extracts data from second file, positioned in a different memory area of internal site, and outputs it to display. At the same time, if page identifier was not found in internal site memory, internal browser reports negative result, and browser of SIM-module, realized in SIM-card, at that moment already transfers a page request to extract the page from Internet network. Mobile phone user does not determine, whether a page should be stored in internal site: instead, this action is performed by mobile communication operator or developer of pages, who uses codes, recorded in content of WML-pages. Operator may also transmit pages with forced broadcasting to mobile phone and save, renew or remove them from internal site without any interference from the user.
