Combination of face recognition methods with watermarking technology for authentication of digital images

As the substantial challenge in providing security of digital images is owners authentication in many security schemes based on cryptography, steganography and watermarking technology, biometric recognition methods are introduced. In the sequel to these studies in presented methodology the combination of biometric recognition methods based on facial images with watermarking technology to perform automated authentication of digital images owners/users is elaborated. Presented approach involves computing reduced face image representation (feature vector) and embedding it in some cover image in a few watermarking schemes. The robustness of watermarking algorithms is measured by identification accuracy results obtained using neural networks (NN).
