Transaction verification method, automatic transaction verification system and transaction verification unit (variants)

Abstract

The invention offers methods and devices in which a clear-back signal and an answer signal of the subscriber device connected to the automated switched telephone network are used as primary or secondary factor of identification of personality and intentions of the transaction initiator. The invention can be used inter alia for confirmation or verification of transactions initiated by the unauthorized person or by the person authorized by existing authorization factors, by means of the subscriber device of the person authorized to make the transaction. The technical result is the fact that an authorization factor is offered that does not require connection traffic in the automated switched telephone network when such network is used for confirmation or verification of transactions.

Description

Field of Invention [0001] The present invention relates to a confirmation method, that is, a multi-factor authentication method and equipment for conducting transactions by telephone. [0002] The trader is generally the first party to initiate a transaction, such as a bank customer, and the second party that has an interest in the transaction verification result, such as a bank, and a third party that performs transaction verification and provides the verification result to the second party, such as a processing center. One of the options in the second party and the third party is to combine. [0003] In the proposed scheme, the on-hook and answering signals of the telephone equipment are used as the main or additional elements for confirming the identity and willingness of the transaction initiator. [0004] In addition, the present invention can be used in private to verify whether a person agrees to perform the act of transferring the rights of the transaction object. Th...

Problems solved by technology

[0009] One disadvantage of this system is the high cost of receiving payment transaction verification due to the high cost per minute in the public switched telephone network, the need to remember a PIN for the customer to use the system, and the fact that the system cannot be used for small payments , because the verification fee may exceed the transaction amount

[0010] The general disadvantages of existing systems are that dial-up connection times are long, the user requires high knowledge of the verification service infrastructure, verification results are dependent on accidental input errors by customers, and verification is multi-level and slow

The existing multi-level approach brings obvious inconvenience to mobile phone users while on the move, such as driving, between subway stations, etc.

These shortcomings make it difficult to implement multi-level transaction verification, such as verification for private daily business (the cumbersome verification makes users annoying), and verification for exchange business requires the instantaneous response of participants to quickly change the transaction status

[0011] Therefore, the method of effective transaction verification with the user having a minimum participation request cost below the instance during the verification process remains unsatisfied
