Problems solved by technology

Compared with ordinary magnetic cards, the chip card uses the CPU chip of the central processing unit, which has the advantages of independent calculation, encryption and decryption and storage capabilities, and the card itself is not easy to be copied. Card plus PIN payment, and chip card can also be used for non-password payment, but for non-password payment, there are certain security risks. For chip card plus PIN payment, the operation is more complicated and the efficiency is not high

Abstract

The embodiment of the invention discloses a chip card and a password-free authentication method based on the chip card. The chip card comprises a fingerprint recognition module, a CPU module, a storage module and an output module, wherein the fingerprint recognition module, the CPU module, the storage module and the output module are packaged in a card body. The storage module is used for storing pre-stored fingerprint information so that the CPU module can access the pre-stored fingerprint information. The fingerprint recognition module is used for collecting fingerprint information of an operator and transmitting the fingerprint information to the CPU module. The CPU module is used for reading the pre-stored fingerprint information from the storage module, carrying out matching judgment on the fingerprint information and the pre-stored fingerprint information, and transmitting the judgment result to the output module. The output module is used for transmitting the judgment result to a receiving terminal of the chip card so that a processing terminal of the chip card can carry out identity authentication on the chip card. By means of the chip card, the authentication efficiency of the chip card can be improved, and the authentication safety of a card activating person can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of chip cards, in particular to a chip card and a passwordless authentication method based on the chip card. Background technique [0002] Chip card (Integrated Circuit Card, integrated circuit card), also known as smart card (Smartcard), smart card (Intelligentcard), microcircuit card (Microcircuitcard) or microchip card, etc. It is to embed a microelectronic chip into a card base that meets the standard (such as ISO7816 standard) and make it into a card form. Due to its inherent advantages of information security, portability, and relatively complete standardization, chip cards are being used more and more in fields such as identity authentication, banking, telecommunications, public transportation, and parking lot management, such as second-generation ID cards, bank cards, etc. e-wallets for mobile phones, SIM cards for telecom mobile phones, bus cards and subway cards for public transportation, and park...
