Abstract

Large amount of medical information of patients to be maintained in online, hence more uploading is needed, which may reflects the problem in amount of time and privacy of information. This can be solved by watermarking which provide privacy and cryptography provides security. The proposed algorithm provides a single system of cryptographic watermarking method. Initially the patient information is encrypted using the symmetric key and then while hiding, the key will be extracted to retain the quality of the medical image after copyright extraction. During authentication the embedded information is extracted and decrypted. Further, the decrypted information is compared with the patient information. Finally, the extracted key is used to recover the medical image.The algorithm gives high payload capacity, less computational complexity, privacy of the patient and good reversible quality.
