Steganography over Redundant Residue Number System Codes

Abstract

In this paper we define steganography over Redundant Residue Number System (RRNS) Codes. We describe distortion-less RRNS based steganographic schemes, analyse their corresponding embedding capacities, discuss their linearity and compare them with well known steganographic protocols. Specifically, we take advantage of the redundancy and correction capacity of these codes to hide secret information in such way that the number of the altered residues does not exceed half the redundancy of the code.
