A high density information concealment technique for digital rights management of MPEG coded video

As multimedia commerce grows, content distributors' needs for digital rights management schemes that provide flexible access control becomes more and more eminent. This paper proposes a digital rights management scheme that can provide pay-per-play access control in pre-distributed video applications. The paper explains the scheme and proves through an evaluation of its communication overhead, computational overhead and security that this scheme provides a favorable solution for pay-per-play access control requirements.
