I nformation Hiding in Email Services Based on Confused Document Encrypting Schemes
We-Shyun Pan, Quincy Wu · Proceedings of the Asia-Pacific Advanced Network · 2010
Confused Document Encrypting Scheme (CDES) is a document protection technique for information hiding (steganography), and it uses meaningful cheating text to confuse attackers. It is a simple and effective file protection scheme. In this paper, we proposed a new web application based on CDES, which apply with the email service, and we focus on the web service development and improve some known issues in CDES by a new method which is adding image-hiding technique to protect the position index file (PIF), and we choose a suitable compression and encryption algorithm to increase performance for CDES in my system.
