Copyright Protection Using Non Linear Forward Feedback Shift Register And Error-Correction Technique

Copyright Protection Using Non Linear Forward Feedback Shift Register And Error-Correction Technique

Summary and Conclusion
In this paper, we have presented a review of the field of Steganography and concentrated on improving the security of the data hidden by first crypting data by strong crypting mechanism using NLFFSR and then further error coding it for much improved security. After it we hide this data in the image using the LSB insertion technique. This technique of hiding secret information is highly safe and reliable to hide the Copyright in the Images. By choosing the best techniques of different fields we achieve the best security in the method of Steganography to hide Copyright. Illustration of this Technique using a Image of a sample map.
