Secure and efficient DRM watermark algorithm of forensics in mobile internet

Abstract

With the development of mobile Internet technology, the characteristic of easy editing, transmitting, and forging the digital media bring great challenges in authenticity of multimedia. Due to that, the focus on the digital forensics and identification, such as source identification, content authentication, and information integrity, have become an important research content in the field network security, forensic science and other fields. To solve this problem, in this paper, we proposed an image digital rights management scheme for mobile Internet forensics based on watermark with high-level security and traceability. In this scheme, we embed some user-identity-related and device-related information of mobile phones as a source identification of snapped photos and stored pictures; once the forwarded image data from mobile phones are misused such as spreading the image data on Internet without authorization, especially the confidential image data, we can trace the misuse responsibility by extracting the mobile phone data embedded in the mobile photos. Finally, we evaluate the proposed security and efficiency of the DRM watermark scheme for mobile Internet, a large amount of experiments manifest the proposed watermark scheme is robust, secure, and efficient for the protection and misuse tracing of mobile image data.
