PURPOSE: A call authentication method and a computer readable recording medium which records a call authentication program in an e-business transaction by using a call authentication terminal providing a non-repudiation function with connection of a trusted party are provided to confirm authenticity of the e-business transaction with a call for the call authentication terminal. CONSTITUTION: A call authentication request terminal(10) transmits a personal identification number(PIN) to a trusted third party(TTP) server(40) through an e-business server(30). The TTP server compares the stored PIN with e-business history information and an inputted PIN corresponding to an e-business transaction of the call authentication request terminal and the e-business server. The TTP server encodes combination data of the e-business history information and the inputted PIN number. The e-business server transmits a call approval request for a call authentication terminal(80) to an interactive voice response(IVR) server(50).
