摘要：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.
关键词：multiple letters; tamper detection; text documents; text watermarking.
