Only combining encryption with fingerprinting together can provide comprehensive content security protection for visual media. Joint fingerprinting and decryption (JFD) framework solves encryption and fingerprinting simultaneously and has high efficiency, but several problems still remain to be tackled in JFD, including poor encryption security, severe fingerprinted image distortion, etc. An im...

Digital fingerprinting is a technology for tracing the distribution of multimedia content and protecting them from unauthorized redistribution. Collusion attack is a cost effective attack against digital fingerprinting where several copies with the same content but different fingerprints are combined to remove the original fingerprints. In this paper, we investigate average and nonlinear collus...

Audio fingerprinting is the process to obtain a compact content-based signature that summarizes the essence of an audio clip. In general, existing audio fingerprinting schemes based on wavelet transforms are not robust against large linear speed changes. The authors present a novel framework for contentbased audio retrieval based on the audio fingerprinting scheme that is robust against large l...

An audio fingerprint is a compact content-based signature that summarizes an audio recording. Audio Fingerprinting technologies have attracted attention since they allow the identification of audio independently of its format and without the need of meta-data or watermark embedding. Other uses of fingerprinting include: integrity verification, watermark support and content-based audio retrieval...
