【 摘 要 】

In healthcare industry, the patient`s medical data plays a vital role because diagnosis of any ailments is done by using those data. The high volume of medical data leads to scalability and maintenance issues when using health-care provider`s on-site picture archiving and communication system (PACS) and network oriented storage system. Therefore a standard is needed for maintaining the medical data and for better diagnosis. Since the medical data reflects in asimilar way to individuals? personal information, secrecy should be maintained. Maintaining secrecy can be done by encrypting the data, but as medical data involves images and videos, traditional text based encryption/decryption schemes are not adequate for providing confidentiality. In this paper, we propose an algorithm for securing the DICOM format medical archives by providing betterconfidentiality and maintaining their integrity. Our contribution in this algorithm is of twofold: (1) Development of Improved Chaotic based Arnold Cat Map for encryption/decryption of DICOM files and (2) Applying a new hash algorithm based on chaotic theory for those encrypted files for maintaining integrity. By applying this algorithm, the secrecy of medical data is maintained. The proposed algorithm is tested with various DICOM format image archives by studying the following parameters i) PSNR - for quality of images and ii) Key - for security.
