Abstract: Image watermarking can be defined as a technique that allows insertion of imperceptible and indelible digital data into an image. In addition to its initial application which is the copyright, watermarking can be used in other fields, particularly in the medical field in order to contribute to secure images shared on the network for telemedicine applications. In this report we study some watermarking methods and the comparison result of their combination, the first one is based on the CDMA (Code Division Multiple Access) in DWT and spatial domain and its aim is to verify the image authenticity whereas the second one is the reversible watermarking (the least significant bits LSB and cryptography tools) and the reversible carte mapping RCM its objective is to check the integrity of the image and to keep the Confidentiality of the patient data. A new scheme of watermarking is the combination of the reversible watermarking method based on LSB and cryptography tools and!
the method of CDMA on the field of spatial and DWT domain to verify the three security properties Integrity, Authenticity and confidentiality of medical data and patient information .In the end ,we made a comparison between these methods within the parameters of quality of medical images Initially, an in-depth study on the characteristics of medical images would contribute to improve these methods to measurements have been done on the watermarked image to verify that this technique does not lead to a wrong diagnostic. The robustness of the watermarked images against attacks has been verified on the parameters of PSNR (Peak Signal to Noise Ratio), MSE (Mean Square Error),MAE (Mean Absolute Error) and SNR(Signal to Noise Ratio ) which show that the resulting quality of combination watermarking method is good in DWT than in spatial domain.
Keywords: watermarking, Reversible watermarking, CDMA, Integrity, Authentification, Confidentiality, Combination.
