  • Publication number: 20110194690
    Abstract: A watermarking system uses distinct bit patterns to identify a logic 0, a logic 1, and a marker bit, which demarcates segments of logic bit information. Marker bits, which are printed on both foreground and background areas of an image, outline message blocks. In message extraction, a preprocessing step removes any white boarders, identifies the best defined corner of a message block, crops the image, and rotates the image to place the identified corner at the top-left corner. Message extraction scans the rotated image in window segments of increasing size during multiple cycles. During each cycle, if a bit pattern cannot be identified as a data bit, then the size of the examined bit area is increased and rechecked to see it specifically is a marker bit. If no bit information can be definitively identified, then it is assigned a logic bit value based on a 50% random assignment.

  • Patent number: 7539871
    Abstract: Conventional virus detection software monitors incoming arrivals of network traffic. Retroactive analysis and/or monitoring of previously accepted traffic is not included in the scope of protection. A retroactive virus detection and propagation history tracking mechanism provides identification of successive recipients of a newly discovered virus which may have eluded detection during the lag time prior to effecting the detection of a new virus. A propagation history maintains a set of recipients receiving a potentially harmful transmission. Upon detection of a particular transmission or portion thereof as being a virus, the propagation history contains a set of infected recipients, which the tracking mechanism notifies so as to perform remedial action and contain the virus to the known set of infected recipients. In this manner, configurations of the invention maintain a set of successive recipients of a virus, and retroactively track and contain the newly propagated virus once detected.

  • Publication number: 20090022314
    Abstract: In a personal information access system 1, a bar-code information output 106 of an information processing device 10 makes bar-code information by associating personal information with term information defining a valid period of the personal information, a password, and terminal-identification information unique to an access terminal 20 permitted to gain access, and the bar-code information is printed on a paper medium M. The access terminal 20 displays only the personal information permitted to output by an output controller 204, on a display part 205. When the personal information is bar-coded with the valid period being set, in addition to encryption, the security level of personal information is synergistically enhanced and it is feasible to ensure prevention of leakage of personal information to third parties.

  • Patent number: 7415612
    Abstract: An image decrypting apparatus derives spectral reflectance of the face of an original on the basis of obtained original image data, built-in light source data and basis function data, and obtains weighted coefficients of each pixel as object color component data. The apparatus stores a file including the basis function data used at the time of obtaining the spectral reflectance as a key file, and stores a file including the object color component data as an encrypted file. From each of the key file and the encrypted file, the original image data cannot be reproduced. By using the key file and the encrypted file in a correct combination, the original image data can be reproduced. In such a manner, the original image data can be protected.

  • Patent number: 7409555
    Abstract: A system and method are presented for assuring electronic documents containing active content. Aspects of the system and method are directed to storing a copy of input data called by the active content in a first invocation of the electronic document, then, on subsequent invocations of the electronic document, using the stored copy of the input data instead of calling for input data from the computing environment. In this way, the output from the subsequent invocations of the electronic document are the same as the output from the first invocation of the electronic document.
