Business model in Web environments is usually provided by multimedia data. Information exchange between users and service providers should be made in encrypted data. Encrypted data are secure from being hacked. Application of DB encryption is a main technology for contents protection. We have applied the access control based on RBAC and prevented the unauthorized users from using the contents. In this paper, we propose a new DB encryption scheme which uses RHAC and digital signature based on PMI.
