Research of secure transaction model based on integrated technique
Fei Yu-lia · 2004
The security gap in network secure transaction model based on digital signature was found out by analyzing mechanism of digital signature.The security gap is that the model didn’t authenticate information’s integrality and facticity.Because a fragile watermarking wen an advantage over authentication of multimedia information’s integrality and facticity,a novel network secure transaction model combining fragile watermaring,steganographia and encryption was proposed.According to the analysis, entity authentication of the digital signature and content authentication of the fragile watermarking was achieved,and at the same time,the sender’s denial and receiver’s falsification could be avoided.Transaction information could be secretly and securely ex- changed each other in the internet.
