Development of an Efficient Watermarking System
for Information Hiding and Protection of DNA sequences

Introduction

Due to vast growth of internet, information production rates are increased. Every day large amount of information is produced as compared to previous day. The use of internet has also made the data vulnerable. Several redundant copies of same data can be produced and there is no evidence that whether these copies are generated from the original licenser or by any plagiarist. In order to keep track of our data on the internet and retain the rights of patent-ship, we need a mechanism that can make an association between the product and its owner. The most common utilization for DNA watermarking is to embed ancestor information in the offspring. These signatures can be extracted from the data at any place to trace back the roots of different generations. Such signatures can also help in the use of genetically modified organisms (GMOs) in order to check whether these, task oriented, organisms belong to the original owner or any intruders. In the domain of biotechnology, genetically modified organisms are created specific to their utilization purposes. The GMOs find their functionality in primarily in agriculture, pharmaceuticals and drug development industry. These organisms can also be used illegally by any third party. So, in order to embed the patents information, we intend to develop a DNA watermarking system. DNA sequences of these organisms are watermarked, so that they can be tracked by the authority to legalize their use and counter intercept any illegal actions. In the same way as the storage of watermark, any user data can be stored in the genetically crafted organisms, in order to use them as information storage devices. very purpose of this project is to develop a system that can successfully watermark the required information of parent or race etc. into the organisms. Such a system will allow us to store secret information in the living organisms and store them for a number of generations. Many kinds of spontaneous reactions are taking place at molecular level in the constituent bases of DNA sequences. These changes alter the sequence of bases, hence disturbing the functionality of a DNA. Therefore, these mutations may destroy the data stored in watermarks. The purpose of project also extends to avoid the effects of these mutations causing the loss of data. We tend to increase robustness of the method to minimize the loss of data because of any unwanted adverse effects.
