Abstract

A framework for protecting multimedia content based on user biometric information and a layered encryption/decryption system is proposed in this chapter. Encryption schemes that require a password are susceptible to issues with illicit key exchange. It is feasible to reduce the unauthorized use of protected content by using hardware identifiers and biometric data as keys. This is achieved by combining the symmetric and asymmetric key systems. The proposed method’s computational needs and applicability are also discussed. The results of experiments involving time-measurement-related encryption and decryption are also presented. Watermarking technologies can be utilized in addition to the suggested approach to allow for the creative uses of protected multimedia data.

Keywords: Multimedia, multimedia content, content protection, encryption, decryption
