摘要： A system and method for marking, coding and tracking a film print in an efficient, adaptive and customized manner for providing unique and robust identification of each individual film print and for facilitating accurate tracking of the origin of a pirated copy is described herein. A film print to be marked is calibrated and provided in computer-readable form for input to a prescreening device. The calibrated film print is reviewed and ideal locations on each frame of the film print are chosen for applying a mark. A unique coding scheme is generated for each desired print. If a pirate copy is found, all marks are located and a matching serial number (e.g., coding scheme) is determined for the pirated copy based on marks found in the pirate copy when compared to a database storing film print mark information generated during the marking and coding process.

摘要： An apparatus and a method for controlling distribution of digital content from an device attached to a network to another device outside the network. The device receives a digital signal containing content, the digital signal having an authorization field indicative of a first transport mode authorizing the content for distribution outside the network, and of a second transport mode wherein the content is not authorized for transmission outside the network. The method comprises the steps of receiving location information of a router on the network for routing content to devices outside the network, receiving destination data indicative of location information associated with a destination device to which the device intends to distribute the content, determining whether the destination device is outside the network based on the router location information and the received destination data examining the authorization field and, inhibiting transmission of the content if the destination device is outside the network and the digital signal is in the inhibit mode.

摘要： A method for providing local security of audio and video content during transmission and storage within digital home networks. Scrambled content may be recorded in all conditions, however, only authorized copies are processed for descrambling and viewing. Content is protected within a network by rebundling the keys required for descrambling, e.g., the TDES keys, into a new ECM (LECM), which is protected by a local public key.

摘要： An apparatus for marking a film copy includes a mapper and a coder. The mapper maps a print identifier to be associated with the film copy into a serial number comprising a sequence of J numbers. The coder creates at least two-error correcting numbers, e.g. Y and Z, as a function of one, or more, of the J numbers. The film copy is then marked in accordance with L numbers, which comprise at least the two-error correcting numbers Y and Z.

摘要： A method and a system for identifying a copy of an image sequence which is presented on a screen. At least one identifier distinct from the image sequence can be projected through the screen such that the identifier is displayed using visible light along with the image sequence. The identifier can be presented at periodic intervals and can define a theater location, a date and/or a time. A color and/or an illumination of at least a portion of the image sequence presentation can be measured. Based on the measured illumination and/or color, a projection brightness and/or color can be determined for the identifier. Also, a location on the screen through which the identifier should be projected can be determined.

摘要： A device for sensing unauthorized use of an electronic security device has a host device and a detector with a loop antenna associated with the port that receives the electronic security device, such as a smart card. The host device comprises a housing having the port formed therein. In one embodiment, the port detector senses radiation emitted from unauthorized use of the electronic security device by attachment of hot-wire conductors to the security device, which conductors carry currents through the port and the detector. In an alternate embodiment, the dielectric constant of the electronic security device is measured and compared to a predetermined value for distinguishing a nominal device from one with attached hot wiring.
