    Abstract: An object of this invention is to increase the encoding efficiency of attribute data of each pixel of image data by using the fact that the probability that the attribute flag data of adjacent pixels have the same bit position is higher than the probability that the attribute flag data of adjacent pixels have the same value. In the first phase, to encode 32×32 attribute data having a size of 8 bits corresponding to one pixel, input attribute data is directly output to an encoding unit and encoded. In the second phase, “7” is set in a variable i as the initial value. Eight attribute data are input. Eight-bit data including bits i is generated and output to the encoding unit. The data of bits 7 of 32×32 attribute data are encoded. After that, the variable i is changed to “6”, and the same process described above is executed. This process is repeated until the variable i reaches 0. The amounts of encoded data generated in the first and second phases are compared. Data with a smaller amount is selected and output.

    Abstract: A system authenticates an original hardcopy document using a digital signature generation system and a digital signature verification system. Initially, the original hardcopy document is scanned to provide a bitmap image to the signature generation system. The bitmap image is highly compressed by the signature generation system using compression schemes such as MPEG (for gray images) or a low-fidelity symbol based compression scheme (for bi-level images). A signed hardcopy document is then printed that includes the bitmap image and an authentication token. The authentication token is encoded in the signed hardcopy document using either serpentine halftone patterns or data glyphs. The authenticity of the signed hardcopy document is verified by inputting a scanned bitmap image of the signed hardcopy document into the signature verification system. Once received, the signature verification system decodes, authenticates, and decompresses the bitmap image to define decompressed image data. The decompressed image data is then output to a display or printer and compared with the signed hardcopy document to determine whether it is authentic.

    Abstract: Systems, methods and storage mediums are disclosed for processing images and two-dimensional barcodes for two-way verification of document data. In one exemplary embodiment, image data of a document is obtained, processed and rendered into a barcode for incorporation into a reproduction of an original image of the document. The resolution of the barcode may be higher than the resolution of the original image which allows the size of the barcode to be reduced. Moreover, the amount of data associated with the original image may be decreased which allows for smaller data storage requirements and faster data transfer of the document.
