Steganography is the science that can hide messages inside images, videos or sounds where the hiding process is known by the sender and the receiver of the message. In this paper we present the Message Processing-based Steganographic Algorithm (MPSA), a new technique to conceal the secret message in a pseudo-random way inside of the cover object using the Karhunen-Loève transform. The paper describes the algorithm and presents an analysis of the results obtained from experimental tests.
