Still Image and Video Fingerprinting
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 and texture  descriptors,R-trees and Linear Discriminant Analysis (LDA). The second is a two-step, coarse-to-fine video fingerprinting method that involves color-based descriptors, R-trees and a frame-based voting procedure. Experimental performance evaluation is provided for both methods.
