Secure Electronic Document Interchange Arithmetic Based on Image Disguise
Guangyong Gao · Jisuanji gongcheng · 2008
Focusing on security problems in electronic document interchange and encryption bringing attention of attacker,this paper proposes a secure electronic document interchange arithmetic based on image disguise.It builds BP model with the vicinity pixels relation of image,transforms output signal of BP model and document into redundancy signal by wavelet transform,and makes them unitary,coding,adding operation.It hides operation result and parameters of BP model into the image after encrypted,and sends the image to receiver.Experimental results show the method has some advantages such as easy operation,unapperceiving,preventing modifications and good security.
