Generation of digital signature from multi-feature biometric traits for digital right management control

Abstract

This paper addresses the issue of ownership of digital images by embedding imperceptible digital pattern in the image. The digital pattern is generated from multiple biometric features in a strategic matter so that the identification of individual subject can be done. The features from iris image and fingerprint image are strategically combined to generate the pattern. This digital pattern was embedded and extracted from the host image and the experiments were also carried out when the image was subjected to signal processing attacks. Experimental results indicate that the insertion of this digital pattern does not change the perceptual properties of the image, and the digital pattern survives signal processing attacks and can be extracted for unique identification.
