Abstract

The digital age is here. One creation of the digital era is that digital media copies are the same as the original. This fact has led to great concern for media theft via illegal duplication. Thus, the need for tracing ownership of such artistic works has spawned the digital data hiding technique known as watermarking. The field of digital watermarking has recently seen vast interests covering theoretical studies, novel techniques, attacks and analysis. Watermarking is defined as the process of electronically attaching the identity of the owner of the copyright of an artistic work in such a way that it is difficult to erase. In this paper we utilize a watermark generation technique based on OPTICAL CODE/SOUND CODE as a security key & same key to extract the data. Here we first crop the image then watermarked the cropped image with inserting the OPTICAL CODE/SOUND CODE as a security key.
