ABSTRACT:
A method, apparatus and computer program product for transmitting data secures the data by adaptively transforming it and spreading the transformed data piecewise over plural transmission channels. The method, apparatus and computer program product may select low-cost channels preferentially to transmit greater amounts of the data; may disorder the data and transmit ordering information separately over a preferred channel of higher security; may conceal data in a lower-security channel by steganographic methods; and may conceal the sequence of the data by placing segments of it statically, for example, in a WWW website, while providing sequencing data on the preferred channel of higher security. A receiving method, apparatus and computer program product may also be provided for recovering information content from signals on the plural channels.
