Description

A financial level security password input device

technical field

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

Background technique

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.

In order to solve the potential safety hazards of fixed physical digital keyboard devices, in recent years, there have been further devices that use software to realize virtual random password keyboards on pure touch screens, and devices that use fixed key positions and use various segment digital tubes to realize digital random numbers. The password keyboard device can relatively effectively solve the problem of being peeped at the input password and potential safety hazards, but there are still some other problems:

1. For the virtual random soft keyboard based on the touch screen implemented by pure software, the user interface experience is not realistic enough as an independent password input device, and it needs to meet certain industry standard anti-attack points in terms of physics and logic, such as It is necessary to use true random numbers that comply with NIST (National Institute of Standards and Technology) standards, no fingerprints can be left when inputting, and the buttons implemented by the software cannot have changing effects when inputting, and the input numbers cannot be displayed , the digital signal of the touch screen must be physically protected; in addition, the screen will be turned off after the device is turned off, and there is no experience of a physical password keyboard for the outside world.

2. Segment code digital tubes to realize fixed keys and random digital display keyboard devices need to occupy hardware resources such as GPIO (General Purpose Input Output) in design, and the product design thickness is relatively thick. In addition, digital Although the combination of light-emitting devices will cause some damage to the user's eyes, in addition, there is no corresponding key value display after the keyboard is turned off, the user experience is average, and the service life of the physical keys is not long.

6. financial level security password input unit as claimed in claim 2, which is characterized in that the real random number generator from Register obtains 10 random numbers between 0~255, is stored in corresponding array, define a size be 10 be used to store with Machine number generates corresponding number key, and whether duplicate Mark Array opens the correspondence array of the deposit from first random number Begin to carry out sequential processes, arbitrary one corresponding digital random number deposit in 0 to the 9 of generation is finally shown to corresponding key mapping The deposit correspondence array in, and to the Mark Array set, indicate used；Circulation includes 0 to 9 until generating 10 digital randomly ordered correspondence arrays in, generate random number.

7. financial level security password input unit as described in claim 1, which is characterized in that the security control unit with Breaking-proof switch is set in the connection line that the touch-control input display unit is connected, and the breaking-proof switch ensures the safety control Interactive information between unit processed and touch-control input display unit is not intercepted and attacks.

8. financial level security password input unit as described in claim 1, which is characterized in that it is single to input display in the touch-control Peep-proof film is set in member, and the peep-proof film inputs the display information that display unit is shown for the touch-control and provides limited visual view Angle ensures that the display information of the display is not peeped.

9. financial level security password input unit as described in claim 1, which is characterized in that it is single to input display in the touch-control Electromagnetism signature screen is embedded in member, the electromagnetism signature screen electronic signature realizes that former person's handwriting compares the demand of business.

10. financial level security password input unit as described in claim 1, which is characterized in that the financial level security password Input unit further includes：

The fingerprint module being connected with the security control unit, the fingerprint module configure fingerprint, realize to intelligent door lock It opens.
