Providing Biometric Protection for Iris using Watermark and Visual Cryptography
Abstract: This paper presents a novel security architecture which protects the iris using watermarking and visual cryptography techniques. The iris region is protected using watermarking technique where we are using DCT to embed the watermarked text image into the iris image in the low frequency band. After performing watermarking, the watermarked image is further processed to generate a template using Daugmans method and Gabor filter. The generated template is then gone …
