Securing medical images : A crypto-watermarking and biometrics based scheme

The protection of medical images during their trans-mission is imperative in healthcare applications. It is essential to provide authentication, integrity control, non-repudiation, and data confidentiality for security purposes. Therefore, we developed in this paper a crypto-watermarking and biometrics scheme. An AES-CFB encryption algorithm using a 256 bits key generated from hashed extracted biometric feature. We processed medical images and obtained relevant performance metrics. The results show that the proposed scheme provides all security requirements and can resist several attacks.
