20100100971 | SYSTEM FOR EMBEDDING DATA - A method and system including receiving marking information, determining, at least in part, based on the marking information, a plurality of color element additives, adding the plurality of color element additives to at least one color element of a video frame, wherein the at least one color element includes a color element R, a color element G, and a color element B. Related methods and systems are also described. | 04-22-2010 |
20100146284 | SYSTEM FOR EMBEDDING DATA - 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 | 06-10-2010 |
20120155755 | SYSTEM FOR EMBEDDING DATA - 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. | 06-21-2012 |

20110197276 | SYSTEM AND METHOD FOR VALIDATING AND CONTROLLING APPLICATIONS - 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. | 08-11-2011 |
20110219457 | SYSTEM AND METHOD FOR INCAPACITATING A HARDWARE KEYLOGGER - 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. | 09-08-2011 |
20120137140 | SYSTEM AND METHOD FOR PROTECTING INFORMATION AND RELATED ENCRYPTION KEYS - 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. | 05-31-2012 |
20120233671 | SYSTEM AND METHOD FOR SELECTIVE PROTECTION OF INFORMATION ELEMENTS - 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. | 09-13-2012 |
20120246472 | SYSTEM AND METHOD FOR SECURED BACKUP OF DATA - A system and method of selectively providing encrypted data is provided. Embodiments of the invention may store data in encrypted form on a storage device. Embodiments of the invention may selectively provide encrypted or decrypted data to a requestor of data based on configuration or other parameters. A filter driver or other module or unit may examine a request for, or communication of data from the storage device and may determine if data is to be provided in encrypted or decrypted form. Decrypted data may be provided to a caching system. A filter driver or other module or unit may examine a request for, or communication of data from the caching system. Data provided from the caching system may be selectively encrypted based on configuration or other parameters. | 09-27-2012 |
20130061284 | SYSTEM AND METHOD FOR EFFICIENT INSPECTION OF CONTENT - A system and method of efficiently inspecting content is provided. Embodiments of the invention may inspect files accessed by an application prior to an activation of the application. Selective inspection of files accessed by an application may be based on a previous inspection. Inspection of files accessed by an application may be postponed or performed concurrently with the access. A prioritized queue may include references to files, a priority may be related to a risk level and an inspection order may be according to a risk level. | 03-07-2013 |
