Abstract. This work proposed a novel scheme for robust watermarking in the encrypted medical volume data, which protects the original medical volume data from the third party embedders. The original medical volume data is encrypted using a selective partial encryption method based on 3D DCT and Logistic Map. In the watermark embedding phase, the watermark is associated with the feature vector of the encrypted medical volume data, generating a key which will be used in watermark extraction. The feature vector of the encrypted medical volume data is extracted in a way combining 3D DWT and 3D DCT. The watermark extraction is performed on the encrypted domain. The proposed watermarking algorithm realizes zero-watermarking technology in the encrypted domain, which has no effects on the encrypted medical volume data. The experimental results show that the proposed watermarking scheme has good robustness to some normal and geometric attacks. Therefore, it has a good practical value.

While transferring the medical images from one place to another place lot of security issues are raised. The security issues are confidentiality, integrity and authenticity. Combined encryption and watermarking technique used to verify the integrity and authenticity of medical images. Encryption algorithms are operated in stream cipher and block cipher mode. Advanced Encryption Standard (AES) algorithm is one of the block cipher algorithm. The proposed method uses Advanced Encryption Standard Algorithm in Cipher Block Chaining (CBC) mode. To increase the security, the proposed technique uses baker key in the original image before applying the AES algorithm. Based on the baker key the image pixel position has been changed. To increase the data hiding capacity this technique embeds the information in the spatial domain and encrypted domain. The main objective of this method is to provide integrity and authenticity of the medical images at the same time increase the information embedding capacity. Experimental security analysis is taken for the 8-bit ultrasound images and 16-bit Positron Emission Tomography (PET) images.

“…The basic principle of this approach is to share a medical image with knowledge digest (KD). The future KD gives the medical description and interpretation of the image content (Gouenou Coatrieux et al, 2009). To share the medical images with some extra header information, header files are prone to manipulation and information loss, which may occur during file format conversion.…”

Protection of medical image content is more significant in telemedicine. Digital lossless watermarking becomes the auspicious technique to secure the medical content in medical images. To enhance the security, this paper suggests secure hash algorithm , rivest-shamir-adlemen algorithm, novel algorithms additive hash function and advanced classical cipher for replacing the existing algorithm and the production of digital signature to achieve high confidentiality and authentication. An image is compressed using joint photographic experts group JPEG 2000 discrete wavelet transforms for region of interest and joint photographic experts group JPEG for region of non interest. The medical image content electronics patient record and digital signature is embedded in region of non interest of compressed image, using lossless watermarking technique. Watermarking technique increases the integrity and authenticity, when medical images are shared through open network. The peak signal to noise ratio value is up to 72dBs for all types of digital imaging and communications in medicine images. Increase in authentication can be achieved when the medical expert access secured medical images from the web servers using Kerberos technique.
