Abstract

The invention provides a POS device identity recognition method, a POS device and a server. The POS device identity recognition method comprises the steps of sending a POS device serial number to a CAauthentication center; authorizing to generate a corresponding digital certificate by the CA authentication center; verifying the legality of the digital certificate by the server to ensure the POS device to have a payment permission while payment transaction; then sending signature data to the server by the POS device after a random number sent by the server is signed through a private key; andverifying the legality of the signature data based on the digital certificate by the server so as to finish identity recognition of the POS device. Through double-verification mode of the server, thePOS device identity recognition method can ensure the security and reliability of payment of the POS device and can prevent the serial number of the POS device from be tampered; meanwhile, the POS device identity recognition method saves precious storage resources and updating maintenance cost of the server and improves the security and reliability of payment transaction as a white list of the POSdevice is unnecessary.

Description

technical field [0001] The invention relates to the technical field of electronic payment, in particular to a POS device identification method, a POS device and a server. Background technique [0002] In the process of realizing the automatic transfer of electronic funds through the POS device, the POS device first reads the magnetic stripe (chip) information of the cardholder on the bank card through the card reader, and then transmits the consumption information to the back-end server of the merchant through network communication , The information is delivered by the merchant background and the bank or third-party payment, so as to realize the online consumption of credit cards, debit cards and other bank cards. [0003] In this transaction process, identifying legitimate POS devices in the merchant's background is one of the important links to ensure the security and reliability of POS transactions.
