Abstract
In this thesis we proposed two methods; the first one is used to treat the problem of blind source separation, which consist to approximate a set of signal sources. The application of this algorithm is based on the principle of wavelet decomposition base. The second is also interested in domain signals but otherwise; a signal encryption technique has been proposed (images) using the singular value decomposition
