Embodiment 1

[0041] A big data iris recognition voiceprint recognition examinee identity authentication system, the hardware structure is installed at the entrance of the examination room, which includes a verification platform 7 and a release device 5 arranged at the entrance of the examination room, the verification platform 7 is provided with a pickup 1, an iris Collector 10, fingerprint identification device 6, RFID reader 8, and examination admission ticket scanner 9, the verification platform 7 is internally provided with codec device 2, AD converter 21, digital signal processing chip 3, data memory 4 and ARM processor twenty two. The iris collector 10 is connected to the AD converter 21, and the iris image information collected by the iris collector 10 is input into the AD converter 21 to be converted into a digital image. The pickup 1 is connected to the codec device 2, and the audio signal collected by the pickup 1 is input into the codec device 2 for A / D conversion. Codec device...

Embodiment 2

[0044] On the basis of the first embodiment, the iris collector 10 is IRISPASS, BM-ET300 or BM-ET500, and the front end of the lens of the iris collector 10 is equipped with an infrared cut filter device. The infrared cut-off filter device can be used to filter out infrared light to collect iris color images.

Embodiment 3

[0046] On the basis of Embodiment 1 or Embodiment 2, the AD converter 21 is an AD converter 21 produced by AD Company whose model is AD7705. AD7705 is an AD converter suitable for low-frequency measuring instruments produced by AD Company. It can directly convert the weak iris image information received from the iris collector 10 into a serial digital signal output without an external instrumentation amplifier. And the AD7705 has achieved good performance of 16-bit error-free code, and the on-chip programmable amplifier can set the input signal gain. The first notch of the digital filter can be set by adjusting the off time and update rate of the internal digital filter through the on-chip control register. With a +3V power supply and a 1MHz master clock, the AD7705 consumes only 1mW. AD7705 is an ideal circuit based on microcontroller (MCU) and digital signal processor (DSP) system, which can further save cost, reduce volume and reduce system complexity. Applied to micropr...

Abstract

The invention disclose a big data iris recognition voiceprint recognition candidate identity authentication system, comprising a validation table and a release device at the entrance of examination rooms; an iris collector, a fingerprint recognition device, a RFID reader and an admission ticket scanner are arranged on the table surface of the validation table; an AD convertor, a digital signal processing chip, a data storage unit and a ARM processor are arranged in the verification table, wherein the iris collector is connected with the AD convertor; the AD convertor, the data storage unit, the fingerprint recognition device, the RFID reader, the admission ticket scanner and the release device are connected with digital signal processing chip; the iris image information collected by the iris collector is converted into digital images by the AD convertor, and then the fingerprint information collected by the fingerprint recognition device, the candidate identity card information read by the RFID reader and the admission ticket information collected by the admission ticket scanner are input into the digital signal processing chip, and the signal is input the ARM processor to control the open and close of the release device.

Description

technical field [0001] The invention belongs to the technical field of identity authentication, and relates to a hardware structure of an examinee examination authentication system, in particular to a hardware structure of a large data iris recognition voiceprint recognition examinee identity authentication system. Background technique [0002] As the scale and number of various examinations increase year by year, although the examination management organization has taken various measures to prevent them, it still cannot effectively eliminate the phenomenon of substitute examinations. The fairness and impartiality of the examination violated the interests of candidates and disturbed the social order. At present, in all kinds of examinations, candidates enter the examination room with the admission ticket, and the monitoring teacher can only judge whether the photos of the candidates on the admission ticket are consistent with the naked eye, and there is no guarantee that can...
