US 2013/0156256 A1 · STEGANOGRAPHIC ENCODING AND VERIFICATION

Abstract

Multi-Dimensional Statistical Patchwork Steganographic Encoding and Verification uses fluctuations in image density and brightness to encode a binary cipher and decode the same in the absence of prior knowledge other than that of the existence of encoding and encoding party source. Once encoded, the image can be deciphered without any prior knowledge outside the encoding preference or hallmarks. This allows a party to encode and image, release it publicly, retrieve it at a later time, and decode it without any other knowledge than it was an image they encoded. Using a statistical representation of a defined segment of the image in a mated pair is used to define either a “I” or “0”. The addition of stereoscopic, alternate frequency bands, or harmonic stacking allows multiplication of available bits without degradation of image appearance. Using any pre-defined hallmarks of origin and pattern allow for non-cataloged reference of the encoded image.

Dependent claims

A computer-based method to encode an image, comprising:

converting an image to an encoding format;
parsing the image into proportional segments;
encoding a plurality of dimension layers of the encoded image with a cipher key, beginning with the smallest dimension layer;
comparing a set of specifications of the encoded image with a corresponding set of specifications from of the original image;
and
releasing the encoded image when a difference between the set of specifications of the encoded image and the set of specifications from the original image is less than a threshold amount.
