Abstract

A data security system for digitized data that can use both encryption and steganographic techniques. Encrypted data (14) is steganographically encoded into a secondary data stream (16), the least significant bit of selected bytes of which are replaced with bits of the encrypted data. Byte selection (15) is performed via ciphertext created separately that uses an encryption key (13) as both key and data to be encrypted. The resulting secondary data stream (17) chosen such that it does not resemble any modification can be stored or transmitted. Decoding is accomplished by using the cypertext to find the selected bytes in the modified secondary data stream, extracting the least significant bits, and reassembling those bits into the original data. Data can be backed up by first encrypting it, then splitting it into multiple parts and storing each part on separate floppy disks in locations selected by separate encryption process which produces a selection ciphertext. The original data is restored by merging the data blocks from each floppy.
