Abstract

Security is the fundamental requirement for an information society in the distributed network environment. A watermark is a secret message that is embedded into a cover message. Digital watermarks are used to verify the authenticity of the carrier signal for the identity of the owners. In order to provide data integrity, confidentiality and authentication various techniques are available like cryptography, steganography and watermarking. To protect the patient information in telemedicine, watermarking is mainly used. Patient information is embedded within the cover medical image. Digital Imaging & Communications in Medicine is an universal standard of communication for secured medical images. In the proposed technique, to provide authentication the hash value will be generated using SHA and the Huffman compression algorithm(R-S vector) will be used to shrink the size of an image. With the patient information the medical image is protected through Public key cryptography in a secure manner. Compared to the previous system, the proposed technique is more efficient. The original image is completely restored without any loss at the receiver side. The patient information is hidden (protected) from the hackers during transmission.
