| 20080244706 | Method of and System For Generating an Authorized Domain - This invention relates to a system and a method of generating an Authorized Domain (AI)), the method comprising the steps of selecting a domain identifier (Domain ID) uniquely identifying the Authorized Domain, binding at least one user (P | 10-02-2008 |
| 20080258863 | Method and a System for Proximity Evaluation - This invention relates to a method and a system for evaluating proximity. A reference object is moved such that it enters at least two different proximity areas of two different proximity indicators, whereby proximity indications are generated. The time difference between the indications is measured. If the time difference is within predefined range it is ascertained that the reference object is within a well defined area. Thus, the fact that the speed of movement of a physical object is significantly limited is used for obtaining reliable proximity evaluations. | 10-23-2008 |
| 20080271158 | Authorized Domain Policy Method - The present invention relates to a method and a device for determining access to multimedia content from an entry identifier, in a domain which comprises a number of entry identifiers, and where the multimedia content is assigned an access number n indicating the number of entry identifiers which may access the multimedia content. This is obtained by accessing a domain list indicating at least some of said entry identifiers in said network domain and by further determining that the entry identifier may access said multimedia content if said entry identifier is between the n entries in said domain list determined by an evaluation rule. | 10-30-2008 |
| 20080282353 | Securely Linked Media Carrying Different Versions of the Same Computer Code - A means of delivering software comprises at least two storage media comprising at least two different versions of a software program. A first version of the software program comprises a full version of the program and a second version comprises a limited version of the program. Due to the presence of identification means, such as a security tag, the first version of the software program can only be executed in the presence of to second storage medium, or vice versa. The security tag may be an RF-ID dongle. Also, a system and a method is provided, for executing data stored on a data carrier, and wherein related data are stored on two separate data carriers. At least one of the data carriers comprises identification means, and the presence of this identification means authorizes the use of one of the data carriers in one of the devices. | 11-13-2008 |
