Secure Data Transmission using Content Fingerprinting Digital Watermarking Techniques

다국어 초록 (Multilingual Abstract)

In order to hinder the unauthorized redistribution of digital data, digital watermarking has increasingly applied to conceal information in digital multimedia data, thus enlisting the watermarking technology in the difficult fight against intellectual property rights infringement. Brought up by the crucial issue of copyright, digital watermarking plays a key role in protecting integrity and providing authorization for multimedia. Fingerprinting is a means to trace the illegally redistributed intellectual property (IP) by creating a unique IP instance with a different signature for each user. Existing fingerprinting techniques focus on lowering the design effort to create a large number of different IP instances without paying much attention on the ease of fingerprint detection upon IP integration. A new framework that enhances the Mobile commerce by the use of content fingerprinting and digital watermarking techniques provides security and privacy to the content owner. The content fingerprinting technique is based on active content fingerprinting in which fingerprint can be hided into image using reversible watermarking of haar transform for secure transmission. The performance of this system can be examined based on peak signal to noise ratio and mean square error and it can be compared with existing methods. Thus digital watermarking technology can be introduced into the field of mobile commerce to provide high level of security for online transactions.
