Device and method thereof for producing and verifying voice signature of message

Abstract

The invention relates to a device and a method thereof for producing and verifying a voice signature of a message. Both a producing end and a verifying end use the same diacritic group containing a plurality of diacritic units inside, wherein each diacritic unit comprises an index value and a diacritic. The producing end converts the message into a message digest by utilizing a hashing function, and captures a plurality of diacritics capable of representing the message from the diacritic group according to the message digest. Then a user reads the captured diacritics to produce the voice signature, and the corresponding relationship between the message and the voice signature can be verified by semantic identification so as to judge whether the voice signature is produced by the user aiming at the message or not.

Description

technical field [0001] The present invention relates to a device and method for generating and verifying an electronic signature for a message; more specifically, the electronic signature of the present invention is a voice signature associated with the user's voice. Background technique [0002] In recent years, with the advent of the Internet age, the commercial behavior of people-to-people transactions through the Internet has become increasingly common, and will become the mainstream of the trading market in the future. However, due to the prevalence of online transactions, there have been many cases of fraud and data theft by hackers, such as: counterfeit identities for online transactions, electronic information content has been altered, and personal accounts have been embezzled and so on. [0003] Currently, there are many security protection technologies for network transactions on the market, among which the most popular one is the digital signature of Public Key In...

Problems solved by technology

However, this digital signature technology based on a set of public keys and private keys still has risks to the user's transaction security, for example: the user loses the private key

[0004] At present, there are risks in PKI digital signatures on the market. The reason is that the technology of PKI digital signatures only provides the link relationship between digital signatures and electronic messages. There is no correlation between the user and the private key, so even if the private key is stolen To illegally generate digital signatures, it is not easy to be detected
