AI Technical Summary

Problems solved by technology

However, if the user loses the right little finger or the fingerprint of the right little finger is destroyed due to an accident, identity authentication will not be possible, and cumbersome procedures are required to modify the fixed password or re-encode the fingerprint
In addition, each person may use more than one network platform or electronic device. When operating different platforms, such as multiple financial accounts or other online trading platforms, it is often necessary to set different fixed passwords for authentication, so users must memorize multiple passwords. Password, easy to confuse and cause inconvenience to users
Furthermore, the average person has only ten fingers, so the fingerprint encoding method in the prior art can only correspond to the numbers 0-9, and the password can only be completely composed of numbers, resulting in a small number of passwords that can be set

Embodiment Construction

[0042] figure 2 The sensor 2 for detecting fingerprints is displayed, which has a turning reference point 4. image 3 Show the flow chart of fingerprint encoding of the present invention. Reference figure 2 and image 3 When performing fingerprint encoding, as shown in step S100, the system will prompt numbers or English letters (hereinafter referred to as alphanumerics) or symbols and display them on a display device 14. The user selects the finger corresponding to the prompted alphanumeric, as shown in step S102. Then, step S104 is performed to touch the selected finger to the sensor 2, and the sensor 2 detects the fingerprint of the finger to generate a fingerprint image to a communication interface 6. In step S106, the communication interface 6 channel-encrypts the fingerprint image to transmit the fingerprint image to the remote memory controller 8. The communication interface can be the signal transmission and reception channel in the device or between the device and th...

Abstract

A fingerprint encoding method, and a fingerprint authenticating method and system are provided; the fingerprint encoding method shows an alphanumeric character or a symbol offered by a system first. Then, users select a desired finger corresponded with the alphanumeric character or symbol to touch the sensor, thereby acquiring a fingerprint image or a fingerprint characteristic value of the finger to save the fingerprint image or the fingerprint characteristic value in a memory area corresponded with the alphanumeric character or the symbol in a memory. A fingerprint authenticating method does not need to set a preset password, while showing a random verification code offered by the system, and users enter the correspondent fingerprints in order according to the random verification code.

Description

Technical field [0001] The invention relates to a fingerprint encoding method and a fingerprint authentication method and a system for fingerprint sensing. Background technique [0002] Some network platforms and electronic devices require identity authentication to avoid illegal embezzlement. The security and operation convenience of identity authentication is a trade-off. The balance of the trade-off depends on its importance. The traditional authentication method is that the user sets a password composed of English letters and / or numbers. Only by entering the correct password can you enter the network platform or use the electronic device. Although the authentication method using a fixed password is more convenient in operation, But it is easy to crack. The current safer identity authentication method is to use fingerprints, which use a sensor to detect the characteristic value of the fingerprint of the finger. When the characteristic value matches the characteristic value of...
