Watermarking text document image using pascal triangle approach

Emergence of internet and other modern digital applications such as electronic publishing and digital library make it easy to reproduce and re-distribute digital contents thus give room to so many copyright violations including plagiarism and other illegal use of contents that need to be resolved.
