Abstract: A system and method for selective protection of information items is provided a one or more information elements in an information object may be identified. Selected information elements in an information object may be encrypted. Placeholders may replace selected information elements. Presentation of information included in the information object may comprise a presentation of placeholders substituting information elements. Contingent on an authentication, placeholders may be replaced by associated information elements. Contingent on an authentication, information elements may be viewed and/or manipulated.

Abstract: A method and system including capturing a video stream including embedded data, segmenting the video stream into a plurality of video frames included therein, locating a color mass, denoted C?, for each color element of every individual video frame of the plurality of video frames by summing color value coordinates for a given color element included in the individual video frame, locating a color mass, denoted C, for each color element of a corresponding individual video frame, the corresponding individual video frame corresponding a video frame which does not include embedded data, subtracting C from C?, and deriving, from a result of the subtraction, a value of a first coordinate and a second coordinate, the first coordinate and the second coordinate including coordinates of a vector, the vector corresponding to a string of bits including information embedded in the individual video frame. Related apparatus, methods and systems are also described.

Abstract: A system apparatus and method for protecting information are provided. Embodiments of the invention may detect inactivity related to a computing device. Information and encryption key may be removed from a memory. Subsequent activity may be detected. An authentication procedure may be performed, and, contingent on authenticating a relevant entity, a master key may be generated and installed in a memory.

Abstract: A method and system for embedding data in video frames is described, the method comprising receiving marking information, representing the marking information as a 2-coordinate vector, denoted ?, where the 2-coordinates are denoted, respectively, ?, ?, such that ?=(?, ?), providing a video frame to be marked, the video frame including a plurality of pixels, each pixel of the plurality of pixels being represented as p, where p=(x, y), x and y including coordinates of pixel p, the plurality of pixels being represented as a triad of color elements, denoted, respectively, as R, G, and B, and marking the video frame by transforming each pixel among the plurality of pixels as follows R?(p)=R(p)+R>, G?(p)=G(p)+G>, and B?(p)=B(p)+B>, where R> represents a dot product operation on p and ?R, G> represents a dot product operation on p and ?G, and B> represents a dot product operation on p and ?B.

Abstract: A system, device and method for incapacitating a keylogger. An inactivity of an input device may be detected. A flow of information from an input device to a computing device may be manipulated. A keylogger may be caused to store redundant information by causing the input device to produce redundant input. Other embodiments are described and claimed.

Abstract: A system and method for validating an application and for controlling execution of an application. A plurality of parameters may be computed for an authenticated object and for a tested object. A plurality of comparison and other metrics may be computed based on the computed plurality of parameters. Control of an execution of programs may be based on said metrics. Other embodiments are described and claimed.
