Embodiment 1

[0038] An identity authentication system applied to big data voiceprint recognition examinations. 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 equipped with a pickup 1 and a fingerprint. An identification device 6 and an RFID reader 8 , the verification platform 1 is provided with a codec device 2 , a digital signal processing chip 3 and a data storage 4 . 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 2, fingerprint identification device 6 and RFID reader 8 are all connected with digital signal processing chip 3, and this fingerprint identification device 6 is used for collecting the fingerprint information of examinee, and this RFID reader 8 is used for collecting the ID card information o...

Embodiment 2

[0041] On the basis of Embodiment 1, the pickup 1 includes a pickup housing 11, a sound-introducing component 12, a fixed pressure plate 13 and a retaining spring 14, and the sound-introducing component 12 and the fixed pressure plate 13 are mounted on the sides of the pickup housing 11, respectively. Inside, the snap ring 14 is set and fixed on the inner side of the pickup housing 11 above the fixed pressure plate, and the purpose of installation and disassembly can be easily achieved through the snap ring structure, and the component structure will not be damaged during the disassembly process. There is a rotatable turntable 131 in the middle of the fixed platen 13 , and the turntable 131 can rotate around the center of the fixed platen 13 on its plane. Further, a plurality of small holes 132 are uniformly arranged on the disc surface of the turntable 131, and the size of the small holes 132 is consistent with the size of the sound inlet hole 21 of the sound inlet part 12, an...

Embodiment 3

[0043] On the basis of Embodiment 1 or Embodiment 2, the codec device 2 is selected as a codec device 2 produced by TI Company as TLC320AD50C, and the TLC320AD50C codec device 2 is a 16-bit high-performance audio signal codec chip.

Abstract

The invention discloses an examination identity authentication system applied to big data voiceprint recognition, belongs to hardware structures of examinee examination authentication systems in the technical field of identity authentication, and aims to provide a hardware structure of an examinee examination authentication system applied to big data voiceprint recognition. The identity authentication system comprises a sound pickup device arranged at an entrance of an examination room, an encoding / decoding device, a digital signal processing chip, a data memory, a release apparatus and a fingerprint identification apparatus, wherein the sound pickup device is connected with the encoding / decoding device; the encoding / decoding device, the fingerprint identification apparatus, the data memory and the release apparatus are all connected with the digital signal processing chip; and an audio signal acquired by the sound pickup device is subjected to A / D conversion through the encoding / decoding device, the converted audio signal and fingerprint information acquired by the fingerprint identification apparatus are transmitted to the digital signal processing chip, and the digital signal processing chip controls an on or off state of the release apparatus. The identity authentication system is suitable for the hardware structures of the examinee examination authentication systems applied to voiceprint recognition.

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 applied to a large data voiceprint recognition examinee examination 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 candidate...
