Adoption of Security Mechanisms in DICOM Images

In our day to day life, health and its issues play a vital role. Developing health care institution has to modernize the patient diagnosis report in secure manner. The increased adoption of information system may lead to inefficient security. To overcome this inefficiency, the security level should be optimized. Health care institution uses three kinds of clinical data, like demographic data, images and textual data (e.g. Report). Medical images play a important role in diagnosis, treatment and research, therefore it is vital to take measures in order to prevent tampering and determine their provenance. Existing work provides information integrity and authenticity for medical images by the use of metadata and watermarking. However, still there are limitations for both approaches that must be properly addressed. This paper uses the basic cryptographic techniques and DICOM standard to provide the information integrity, authenticity, and confidentiality for medical images.
