Abstract
For effective digital rights management (DRM) of multimedia in the framework of embedded systems, both watermarking and cryptography are necessary. Here, we present a novel system in the form of a digital camera that embeds biometric data into an image. Incorporation of encryption and watermarking together in the digital camera will assist in protecting and authenticating image files and Watermarking the digital content with origin information or intended recipient identification secures content from electronic data theft. The invisible watermarking algorithm used here allows for verification of the image as well as the identity of the carrier. In this paper, we present an architecture and a hardware efficient FPGA based invisible watermark module towards the development of the complete digital camera.
Introduction:
In order to improve document and border security, it is proposed to include biometric data such as fingerprints, signatures, etc., in the electronic passport . The key objectives of the passport are to identify the owner, authenticate the document, and copyright the passport [1]. However, there are continuous risks of unauthorized access and modification to the data contained within the passport. We propose that an effective solution to combating unauthorized access such as “skimming” and “eavesdropping” is the judicious use of watermarking [2] and encryption [3]. We have introduced the concept of a secure digital camera (SDC) that has both watermarking and encryption capabilities in [2]. In this paper we present a novel architecture of an invisible watermarking unit which will be integrated in our previous SDC work. We employed the use of parallelism and resource-sharing to meet the timing and area constraints.
