New image encryption method based on ICA

Résumé

In the last decade, Independent component analysis (ICA) becomes one of the most important signal processing tools. Many algorithms have been proposed to separate successfully monodimensional signals from their observed mixed signals. Recently, ICA has been applied to face recognition problem. In this manuscript, a new idea for image encryption and decryption schemes, based on ICA, is proposed. Using some mixing procedure as an encryption method, one can hide useful information transmitted over wireless channels. The main idea of our approach is to secure the transmitted information at two levels: classical level using standard keys and second level (spatial diversity) using independent transmitters. In the second level, a hacker should intercept not one channel but all of them in order to retrieve the information. At designed receiver, one can easily apply ICA algorithms to decrypt the received signals and retrieve the information. Keywords: Decorrelation, Second order Statistics, Whiteness, Blind separation of sources, Image Encryption / Decryption.
