Financial-level security password input device

Abstract

The invention discloses a financial-level security password input device. According to the control of a security control unit, a touch input display unit in the device can simulate a physical entity key in a fixed screen display area to draw key positions of corresponding numeral keys to fixedly display the key positions of the numeral keys and simulate the physical entity key in the fixed screendisplay area to draw key positions of corresponding functional keys to fixedly display the key positions of the functional keys, when the device is in a state that a password needs to be input, numbers displayed on the key positions of the fixedly-displayed numeral keys are random and disordered, and when the device is in a state that the password does not need to be input or in a shutdown state,the fixed numbers corresponding to the positions of the numeral keys are displayed on the key positions of the fixedly-displayed numeral keys. In this way, the problems of difficult actual user embodiment, overall security, scheme implementation and the like of existing pure touch screen random key equipment and segment-code digital entity random keyboard equipment can be effectively solved.

Description

technical field

[0001] The invention relates to the technical field of safe input, in particular to a financial-level safe password input device. Background technique

[0002] At present, in the field of financial payment security, such as banks and other financial places, most of the password input devices for users to enter personal PIN (Personal Identification Number, SIM card personal identification password) to complete transactions are traditional fixed physical keypads, namely The position of the number keys is fixed. This kind of keyboard is relatively weak in terms of confidentiality and security. When the user uses it, it is easy for others to steal the password by observing gestures. It is solved by adding a privacy cover, which increases the cost of the password input device and limits the appearance.

[0003] In order to solve the potential safety hazards of fixed physical digital keyboard devices, in recent years, there have been further devices that use softw...
