A secure access system for controlling access to a plurality of items. The system includes a first IC card reader adapted to receive a first IC card which includes first control information, a second IC card reader adapted to receive a second IC card which includes second control information, and a control integrator receiving the first control information and the second control information and allowing access to a first one of the plurality of items based, at least in part, on both the first control information and said second control information, and to a second one of the plurality of items based, at least in part, on the first control information, without regard to the second control information.
摘要:
A method and system for fingerprinting a content item is described, the content item including a set of content item elements E, providing information uniquely associated with a single user including a string of bits S0, parsing S0 into a plurality of substrings which are functions of S0, providing a matrix of content item replacement elements, each row of which includes, for each member of E, an array of content item replacement elements for Ei, uniquely associating each substring of S0 so that for every substring there exists a corresponding element of E, for every substring, replacing at least one instance of the corresponding element E in the content item with one substitute matrix element for the corresponding substring, and outputting a replacement content item including the result of the replacing, the substitute matrix elements being chosen according to at least one similarity criterion.
摘要:
A method and system for fingerprinting a content item is described, the and system method include providing the content item, the content item including a set of content item elements, the set of content item elements denoted E, such that E={E1, E2, Ei, Em}, providing information uniquely associated with a single user, the information including a string of bits, hereinafter denoted S0, parsing S0 into a plurality of subsequences of strings of bits, hereinafter denoted S1,, Sn, the parsing being performed such that S0 equals a function of S1,, Sn, providing a matrix of content item replacement elements, the matrix denoted R, each row of matrix R including, for at least each one of n members of set E, an array of content item replacement elements for Ei denoted Ri, such that Ri={Ri1, Rij}, uniquely associating each one of S1, Sn with one matrix element of matrix R, so that for every one of S1,, Sn there exists a corresponding element of E, for every one of S1,, Sn replacing at least one instance of the corresponding element E in the content item with the associated one matrix element of matrix R for the corresponding one of S1,, Sn, and outputting a replacement content item including the result of the replacing, wherein the members of Ri for each Ei are chosen according to at least one similarity criterion. Related hardware, systems and methods are also described.
摘要:
A method for displaying device shifted content is described, the method including receiving at a first device, from a first source of content, a plurality of a first type of content items, receiving at a second device, from a second source of content, a plurality of a second type of content items, receiving at the second device, from a third source of content, at least one third type of content item, sending at least one third type of content item and at least one second type of content item from the second device to the first device, and displaying at the first device at least one first type of content item, at least one second type of content item, and at least one third type of content item. Related methods and systems are also described.
摘要:
A system and a method for secure distribution of digital media content through a packet-based network such as the Internet. The security of the present invention does not require one-to-one key exchange, but rather enables keys, and/or information required in order to build the key, to be broadcast through the packet-based network. The digital media content is then also preferably broadcast, but cannot be accessed without the proper key. However, preferably only authorized end-user devices are able to access the digital media content, by receiving and/or being able to access the proper key. Thus, the present invention is useful for other types of networks in which digital media content is more easily broadcast rather than unicast, in addition to packet-based networks.
摘要:
A gaming method for use with an interactive game which is played at a player unit having an interface device which is coupled to a television and to at least one communication network. The method includes displaying, via the interface device, the interactive game on the television, capturing a picture of a player, transferring the picture of the player to a headend, processing the picture of the player to create an avatar of the player, electronically assimilating the avatar into the interactive game, and enabling the player to interactively play the interactive game by controlling the avatar via the at least one communication network. In another preferred embodiment, a gaming method is provided for use with an interactive game in which, at a first player unit, a first interface device is coupled to a first television and to a communication network, and at a second player unit, a second interface device is coupled to a second television and to the communication network. The method includes displaying, via the first and second interface devices, the interactive game at the first and second televisions, and enabling a first player, playing at the first player unit, and a second player, playing at the second player unit, to play along with the interactive game by competing each against the other via the communication network.
摘要:
A secondary content distribution system and method is described, the system and method including a receiver for receiving a plurality of differing versions of secondary content from an provider, each one of the differing versions of the secondary content being associated with at least one of a reading mode, and a connection mode, a processor operative to determine a reading mode of a user of a client device, a selector for selecting one of the differing versions of the secondary content for display on the client device display, the selection being a function, at least in part, of matching the determined reading mode with the reading mode associated with the one of the differing versions of the secondary content and the connection mode of the client device, and a display for displaying the selected one of the differing versions of the secondary content on the client device display. Related methods, systems, and apparatus are also described.
