Hiding digital information using a novel system scheme

This work builds on Lin and Lee's document protection scheme, termed as Confused Document Encrypting Scheme (CDES), to present a novel strategy that could hide digital information and provide secret communication between two communication parties. Lin and Lee invented a document protection scheme to transmit large quantities of secret information. However, their design strategy is only suitable for single-byte character-based text document. The proposed scheme presents a novel strategy that modifies the restrictions in Lin and Lee's work. Any kind of digital data, not only the plain text, can be employed as a carrier or as a secret in the proposed system. The proposed method utilizes the hexadecimal representation of digital data in a manner that ensures it will have many practical applications. In addition, the procedure is easy to implement and capable of transmitting large quantities of secret information.
