The use of telecommunications and information technologies in the medicine domain evolved these last years breathtakingly. This involves the development of the applications bound to the telemedicine. Seeing the importance of this discipline in the improvement of the care quality and in the reduction of treatment costs, the optimization of medical applications performances remains a necessity. In this work, we propose a new and efficient cryptocompression scheme applied to the telediagnostic sector for a secure and authentic medical image transmission. Since only 15% of discrete cosine transform components are encrypted in our approach, a significant reduction in processing time during the encryption and decryption, without tampering the high compression rate of the compression algorithm, can be performed by the proposed scheme.
