METHOD OF ENCODING INFORMATION USING A POSITION-BASED ENCODING SCHEME

Data sequences comprised of figure-coded units, such as text comprised of ASCII characters, are encoded into another data entity, such as a pixel based image. The encoding implements a positionally-based encoding scheme in which values of the data entity (basic matrix) upon which the data sequences are to be encoded is used. The position for values to be changed in the basic matrix are determined by a reversible function, and the encoding value that these values are changed by may be 1, another arbitrary number, or determined by a formula. The counterpart to the reversible function is known by an intended receiver of the encoded data for decoding purposes. The basic matrix may be generated utilizing a suitably complex function, such as a chaos function, with parameters known only to the sender and receiver.
