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.
