Image and video fingerprinting for digital rights management of multimedia data
Nikos Nikolaidis, Ioannis Pitas · 2006
Multimedia fingerprinting, also know as robust/perceptual hashing and replica detection is an emerging technology that can be used as an alternative to watermarking for the efficient Digital Rights Management (DRM) of multimedia data. Two fingerprinting approaches are reviewed in this paper. The first is an image fingerprinting technique that makes use of color-based descriptors, R-trees and Linear Discriminant Analysis (LDA). The second is a video fingerprinting method that utilizes information about the appearances of actors in videos along with an efficient search strategy. Experimental performance analysis is provided for both methods.
