Paper Abstract:
|
The transmission and the transfer of images, in free spaces and on
lines, must satisfy two objectives which are: the reduction of the
volume of information to free, the maximum possible, the public
networks of communication, and the protection in order to guarantee
a level of optimum safety. The standard techniques of encryption
are not appropriate for the particular case of the images. For
this we have proposed a new hybrid approach of encryption-
compression (FMT-AES), which is based on the AES encryption
algorithm of the dominant coefficients, in a mixed-scale representation,
of compression by the Faber-Schauder Multi-scale
Transformation. The comparison of this approach with other
methods of encryption-compression, such as Quadtree-AES and
DCT-partial-encryption, showed its good performance. |
