Abstract:
1. A device for encoding visual information comprising: filtering means to process the input information; image processing means coupled to filtering means configured to extract and process information from the visual information frame by frame; a pattern reader to store and convert each extracted frame into a predetermined number of patterns; and an encryption means coupled to the image processing means to (a) rearrange the patterns into new positions within the pattern of the original aspect ratio and (b) rearrange the patterns rearranged into new positions within the original aspect ratio into a new pattern having a predetermined aspect ratio that is different from the original aspect ratio to generate encoded visual information, wherein the aspect ratio is the ratio of a longer dimension to a shorter dimension of a two-dimensional shape the encryption means also generates a symmetrical encryption key to decode the encoded visual information, the symmetrical encryption key recording the corresponding relationship between positions of the pattern before and after rearrangement by the encryption means.
