ABSTRACT:
Various aspects of data security such as validation, authentication and encryption are accomplished by the combinations of encoding and decoding employing a mapping or inverse mapping controllable by a key k, between a source document x and a transformed document y or a highly compressed transformed document v. In the preferred embodiment, a single mapping module is the basis for an expedient and economic implementation of a unified and comprehensive data security system.
