Secure interaction method and device for terminal and E-bank U-key

Abstract

The invention provides a secure interaction method and device for a terminal and an E-bank U-key, and the method comprises the steps: a detection step: judging whether E-bank U-key verification needs to be carried out or not when a user is detected to carry out operation at a bank APP of the terminal, and if yes, detecting whether the terminal is connected with the E-bank U-key or not by the bank APP; a redirection step: when the bank APP detects that the terminal is connected with the E-bank U-key, acquiring a calling instruction for the E-bank U-key, and redirecting the calling instruction to a secure memory space; an analysis step: performing security analysis on the calling instruction in the secure memory space to determine whether the calling instruction is sent by the bank APP; and a calling step: when the calling instruction is from the bank APP, calling the E-bank U-key based on the calling instruction. According to the invention, illegal calling instructions can be tracked, and the security of the E-bank is ensured.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a secure interaction method and device for a terminal and an online banking U-key. Background technique [0002] With the popularity of smart phones, online banking APPs are gradually becoming popular, which can save users a lot of time and costs. However, hacker technology is also gradually improving, and there are more and more fake online banking APPs. Therefore, how to prevent online banking U-key It is an important technical challenge for the online banking APP to be called by other APPs other than the bank. [0003] In addition, when the online banking U-key is obtained and called by an illegal APP, it is difficult for the existing technology to track the behavior data of the illegal online banking, and it is difficult to analyze and process the illegal online banking. [0004] In addition, in the prior art, the activation function of the neural network is suitable f...

Problems solved by technology

[0002] With the popularity of smart phones, online banking APPs are gradually becoming popular, which can save users a lot of time and costs. However, hacker technology is also gradually improving, and there are more and more fake online banking APPs. Therefore, how to prevent online banking U-key It is an important technical challenge for online banking APPs to be called by other APPs other than the bank

[0003] In addition, when the online banking U-key is obtained and called by an illegal APP, it is difficult to track the behavior data of the illegal online banking with the existing technology, and it is difficult to analyze and process the illegal online banking.

[0004] In addition, in the existing technology, the activation function of the neural network is suitable for the situation where the data is relatively concentrated, but for the behavior data of illegal online banking, the effect is poor, which is caused by the discreteness of illegal online banking data.
