This work presents a new approach of a joint Watermarking/ Encryption algorithm applied in medical domain such as telemedicine, hence the need to keep the visual aspect of medical images and other conservation of the various substituted data. For hiding information, the proposed method uses the Discrete Cosine Transform (DCT) space. For more robustness, the Advanced Encryption Standard (AES) encryption algorithm is proposed. To control identification and eventually the correction (if possible) of the data inserted, it should be noted that we used the serial turbocode to recover the data inserted and after application of several attacks. For evaluation, the IRM images are used. Our proposed method is tested against several attacks, such as the compression, noise, filtering and geometric transformations attacks.
