20140177836 | PICTURE DELIVERING SYSTEM BASED ON VISUAL CRYPTOGRAPHY AND RELATED COMPUTER PROGRAM PRODUCT - A picture delivering system is disclosed including: a picture generating device for outputting a flat picture corresponding to an encrypted picture and for providing a picture ID corresponding to the encrypted picture; and a picture presenting device for utilizing an optical imaging device to capture an image of the flat picture to generate a captured picture, for obtaining the picture ID, and for transmitting the picture ID to the picture generating device. When the picture presenting device passed an entity identification procedure, the picture presenting device obtains a decryption information, processes the captured picture according to the decryption information to obtain a decrypted picture, and then utilizes a display device to display the decrypted picture. The decryption information comprises at least one of a seed key, a mask picture, and a transposition table corresponding to the picture ID. | 06-26-2014 |
20130166916 | DUAL-CHANNEL ELECTRONIC SIGNATURE SYSTEM USING IMAGE CODES AND RELATED COMPUTER PROGRAM PRODUCT - A dual-channel electronic signature system is disclosed, having a signature verification server, a signature requester device, and a hand-held device. The signature requester device calculates a characteristic value related to content of a target document, encodes the characteristic value and a destination message to generate a first graph, and outputs the first graph The hand-held device captures and decodes an image of the first graph to obtain the characteristic value, performs an electronic signature operation on the characteristic value to generate a signature data, encodes the signature data to generate a second graph, and transmits the second graph to a destination network address. If the signature data contained in the second graph passes a verification procedure of the signature verification server, the signature verification server transmits a verification graph corresponding to the second graph to the signature requester device. | 06-27-2013 |
