A Zero-Watermarking algorithm on multiple occurrences of letters for text tampering detection
Journal Title: International Journal on Computer Science and Engineering - Year 2013, Vol 5, Issue 5
Abstract
Electronic publishing has gained importance with the widespread use of Internet. It involves transmission of digital data in bulk from one place to another. It brings various threats to the data in form of illegal copying, redistribution of copyright contents and forgery. Watermarking provides authentication and copyright protection to the multimedia contents over the Internet. This paper presents a zero- watermarking technique that uses multiple occurrences of letters in a word for generation of watermark. This work will help in tampering detection in the text documents.
