ATM cryptosystem

Abstract

The present invention provides an ATM cryptosystem. The ATM cryptosystem comprises: a processing module, a verification module, a publicity module, and a display module. After receiving a transactionrequest, the processing module calls at least one cryptographic element to randomly arrange a cryptographic element combination, sends the cryptographic element combination to the display module for display, and sends position information of the cryptographic element to the verification module; the display module sends received customer input password information to the verification module; the verification module generates a verification result according to the position information of the cryptographic element and the customer input password information; if the verification result is correct,the processing module obtains customer information sent by a banking system, uses the customer information to generate a customer portrait, and sends the customer portrait to the publicity module; and the publicity module determines personalized recommendation content according to the customer portrait and sends the personalized recommendation content to the display module for display. Accordingto the ATM cryptosystem provided by the present invention, the types of cryptographic elements can be flexibly selected, the mode of fixed digital positions is changed, the security of passwords is enhanced, personalized products are pushed, and the functions are more abundant.

Description

technical field [0001] The invention relates to the technical field of ATM encryption, in particular to an ATM encryption system. Background technique [0002] At present, bank ATMs still use the traditional metal password keypad. When the password is pressed with a finger, the temperature of the keyboard will change. If a photo is taken with a thermal sensor immediately after the transaction, the password can be obtained by observing the color depth of the photo. Moreover, the password keyboard only provides ten digits of 0-9, and the customer needs to set a 6-digit password for deposit and withdrawal, transfer, inquiry and other services. The position of the digits is fixed, and the security of the password is poor. In addition, a protective cover is added to the password keyboard, which affects the aesthetics, and the traditional metal password keyboard has a single function and cannot promote product promotion. Contents of the invention [0003] In order to solve the ...
