Fingerprint KEY device

Abstract

The invention discloses a fingerprint KEY device, comprising a chip, a memory, a housing, a power supply, a fingerprint collecting unit, a fingerprint verification unit, a modulation and demodulation module, and an audio plug, wherein the fingerprint collecting unit, the fingerprint verification unit and the modulation and demodulation module are connected with the chip; the audio plug is connected with the modulation and demodulation module; the chip has a chip operation system; the memory is used for storing a private key, a digital certificate, and a fingerprint template; the audio plug includes an MIC (microwave integrated circuit) pole and a sound track pole; the modulation and demodulation module is used for converting an analogue data received from the audio plug into a digital data and then transmitting to the chip, and converting the digital data to be conveyed by the fingerprint KEY device into the analogue data and then transmitting to the audio plug; and the chip can authorize to use the private key and the digital certificate in the memory after the fingerprint verification unit verifies. The fingerprint KEY device replaces PIN code verification with fingerprint verification, and can achieve information interaction of the fingerprint KEY device and electric equipment with an audio interface through the modulation and demodulation module and the audio plug. Therefore, the security and the reliability of identity authentication of a user are improved; and meanwhile, the adaptability and the convenience are also enhanced.

Description

technical field [0001] The invention relates to the field of electronic security, in particular to a fingerprint KEY device. Background technique [0002] With the rapid development and wide application of Internet e-commerce, the communication security of electronic information is increasingly threatened by hackers, network monitoring equipment and viruses. When using the traditional "account name + password" method for user identity verification, hackers can detect the user's keyboard input through video surveillance or Trojan horse monitoring programs, and then steal user account information, causing great harm to the user's privacy and property security. hidden dangers. [0003] The USB KEY device is a relatively common electronic KEY security hardware device. Its built-in chip, memory and chip operating system can store the user's private key, digital certificate and user personal information, etc., and realize the digital certificate and private key through the PIN co...
