In this paper, we propose a new jointwatermarking/encryptionalgorithm for the purpose of verifying the reliability of medical images in both encrypted and spatial domains. It combines a substitutive watermarkingalgorithm, the quantization index modulation (QIM), with a block cipher algorithm, the Advanced encryption Standard (AES), in CBC mode of operation. The proposed solution gives access to the outcomes of the image integrity and of its origins even though the image is stored encrypted. Experimental results achieved on 8 bits encoded Ultrasound images illustrate the overall performances of the proposed scheme. By making use of the AES block cipher in CBC mode, the proposed solution is compliant with or transparent to the DICOM standard.
