Due to the need for increased border security, we present a novel system in the form of a digital camera that embeds biometric data into an image. The embedding process is performed using an invisible watermarking algorithm that allows for verification of the image as well as the identity of the carrier. This paper presents an area efficient and high performance VLSI architecture implementing the invisible watermarking algorithm towards the development of the camera.
