A Novel Selective Encryption DWT-Based Algorithm for Medical Images

The remarkable development of the medical imagery is due to the large use of telecommunications and information technologies in the medical domain. However, since the telemedicine is a medical act that must answer to stern rules, and follow the easiness that is offered by the informatics sciences to violate the confidentiality and authenticity of medical data. To resolve this problem, a lot of methods combining compression and encryption have been developed in the literature to secure the transmission and the storage of medical images. In this paper, we propose a new approach of partial encryption based on the Discrete Wavelet Transform (DWT) and compatible with the norm JPEG2000 in order to assure an optimal and a secure transmission and storage of medical images. This approach is, on one hand, faster since it permits a very important gain in the encryption-decryption processing time (only 6.25% of the DWT matrix coefficients will be encrypted), and on the other hand more efficient because it permits to get an encrypted medical image.
