A Voice Digital Signature Method

Abstract

The invention discloses a voice digital signature method. The voice digital signature method is characterized by comprising the steps that (1) a client-side obtains transaction factor data to provide a variable value for calculation of a digital signature key; (2) key characters are calculated through a key calculation program package in the client-side and are displayed; (3) a voice acquisition module on the client-side records and reads an audio file of the key characters and uploads the transaction factor data and the audio file jointly to a remote server for storage. According to the voice digital signature method, the voice acquisition module is used for recording and reading the signature key, the audio file and the transaction factor data are correlated and stored so that the audio file and the transaction factor data can be used for follow-up identity determination, and paperless transaction is truly realized; besides, the voice digital signature method is safe and unique and can prevent denial.

Description

technical field [0001] The invention relates to a computer network transaction security technology, in particular to a voice digital signature method. Background technique [0002] With the development of the Internet, e-commerce has gradually become a new mode for people to conduct business activities. Digital signature is currently the most widely used, most mature technology and most operable electronic signature method in e-commerce and e-government affairs. The so-called "digital signature" is to generate a series of symbols and codes to form an electronic password for signature through certain cryptographic operations, instead of writing signatures or seals. Therefore, in network applications, digital signatures are more superior than manual signatures. Digital signatures can be used to solve problems of forgery, repudiation, impersonation, tampering and identity authentication, such as online signing, online ordering, and online public discussion. secure transmissio...

Problems solved by technology

However, this kind of encrypted confirmation method also has flaws, which are reflected in the user listening stage, there are loopholes, there is no comparison record in the later stage, and it is impossible to determine whether there is really a listening confirmation, especially when it is applied to financial transactions, the confirmation process is Very strict, and the current compensation method is to add additional signatures to the vouchers, which are scanned by the staff and recorded for archiving, so that it is impossible to truly achieve electronic paperless
