Region based undetectable multiple image watermarking

Abstract

Today detectability of Intellectual Property in the digital world is a major issue. And a watermarking is one of them process to secure intellectual rights of digital assets. In our paper we propose a method to insert multiple watermark in spatial and frequency domain to make our assets secure and undetectable by dividing our host image into two regions, called region-A and region-B. In a region-A, an owner information is inserted with the help of LSB technique and in another, region-B, a circular watermarks are inserted with additive watermarking technique in DWT-DFT domain.
