Secure multimedia objects management in medical information system

Secure and efficient management of multimedia objects in medical information system have become a necessity in today's global environment. To strengthen the security level already present in the database management system and to avoid illegal access to comprehensive content of database including patient's information, we propose in this article a mechanism using the content-based watermarking technique. Information of patient and a digest are encrypted, before being embedded into LSB's bitplane of image associated to the patient. This image is directly integrated into the database. The edge map and invariant moments are used to check the integrity of the image.
