Identity authentication method, device and system

Abstract

The embodiment of the invention provides an identity authentication method, a device and a system. The device comprises a boot command input unit, an PIN input unit, a cryptogram mode selection unit, a storage unit, an interference unit, a cryptogram generation unit and a display unit, wherein the boot command input unit receives a boot command which is input by a user according to the external transaction page demands in order to generate a multi-element cryptogram, and executes the boot motion; the PIN input unit reminds the user of the PIN input request and receives the PIN input by the user; the cryptogram mode selection unit reminds the user of a multi-element cryptogram generation mode selection request and receives a multi-element cryptogram generation mode input by the user; the storage unit stores a user key and a cryptographic algorithm; the interference unit acquires an interference factor; the cryptogram generation unit generates a multi-element cryptogram according to the interference factor, the user key and the corresponding cryptographic algorithm; and the display unit displays the multi-element cryptogram which is to be input to the external transaction page. The invention is used for solving the problems in identity authentication and transaction authentication of internet banks and other financial transaction systems.

Description

technical field [0001] The present invention relates to identity authentication and transaction authentication technology, in particular to the identity authentication and transaction authentication technology of financial transaction systems such as online banking, and specifically an identity authentication method, device and system. Background technique [0002] In the prior art, there are several schemes for identity authentication and transaction authorization authentication as follows: (1) Static passwords: users often set weak passwords when using them, such as birthdays, phone numbers, etc.; they are easy to be stolen and monitored, such as through Trojan horses Stealing and network sniffing, etc. (2) Scratch cards and dynamic password cards: realize one-time encryption, but the security of transaction data cannot be guaranteed, and there is a risk of transaction data being tampered with. (3) Time-based dynamic token: a time-based one-time password generator that ca...
