To prevent "activation" photos from being muddled through, databao "live detection + face recognition" makes face brushing safer

With the development of face recognition technology , More and more commercial applications , Face login 、 Face payment 、 Face lift 、 Face gate, etc , In security 、 Finance 、 education 、 Widely used in medical and other fields , The intelligent and fast face recognition technology has developed rapidly in China .

But face recognition is easy to be photographed 、 video 、 Simulation mold and other ways to muddle through , The public security department has been in Shanghai in recent years 、 Zhejiang 、 anhui 、 Jiangsu and other places found , Several suspect use deep synthesis technology , Illegally stolen or paid for photos and audio “ activation ”、 Synthesize into dynamic video for illegal profit .

“ In vivo detection + Face recognition ” Become a confrontation “ activation ” Photo The key technology

To prevent “ activation ” Your photos muddle through , Data treasure is providing “ Face recognition ” Data service , It provides customers with “ In vivo detection ” Algorithm .

Based on data treasure " In vivo detection " The algorithm can judge the face captured by the camera , Is it a real face or a fake face , Generally, it is used in application scenarios with high security requirements , Can use face recognition + The method of combining living body detection to carry out identity verification , After using in vivo detection , It makes up for the deficiency of single face recognition , Can effectively identify photos 、 video 、 Mask and other fake human faces , Avoid fraud to the greatest extent .

Data treasure as “ Internet +” Trusted authentication platform （CTID platform ） Our first tier partner , Data resources are directly connected to the public security database , After obtaining the user's authorization , By name 、 ID number 、 Portrait photos 、 In vivo detection can verify the authenticity of user identity information in real time . Identity verification as a more secure standard , Data treasure “ Face recognition comparison interface + In vivo detection SDK” The verification process is as follows ：

1. Portrait information collection

adopt SDK、H5 page 、 Wechat applet and other application scenarios obtain the verified face information 、 ID information , Users upload ID photos , System use certificate OCR Recognition technology automatically extracts information , Users take live video and upload it for comparison and verification .

2. Living determination

By using speech recognition 、 Lip recognition 、 Technologies such as living body judgment automatically detect video , Judge whether you are a real living body and upload the human image in the video with high quality .

3. Public security big data verification

be based on https+MD5 Signature authentication + Symmetric encryption technology will portrait image 、 full name 、 The ID number information is encrypted and transmitted to the interface authorized by the Public Security Bureau , And then automatically connect with the portrait image in the public security big data 、 full name 、 Carry out authoritative comparison and verification of ID number .

4. Output verification results

After the verification of public security big data interface , Return the verification result , If the verification is consistent, it will be approved by default , If not, return to the certification homepage , Let the user re operate .
