This paper presents, a new technique for compression and secure image coding that is based on IFS. A multiresolution access control algorithm based on the convergence control of iterative image reconstruction process is investigated. For multimedia applications an icon representation of low image quality is extracted directly from the encrypted data ow thanks to the partial self-anity properties inherent to Local-IFS. The robustness of our scheme is due to the inherent high correlation of image data and to the non-linear decoding process.
