Application Status of Face Recognition Products for Chinese Public Security

As one of the bio-metric identification technologies, face recognition is widely used in the field of public security due to its non-contact collection characteristics and good user acceptance. Currently, mature and typical face recognition products companies on the market include: Google companies and Facebook companies in the United States; Yitu Technology, Beijing Kuangshi Technology Co., Ltd., Jinshi Technology Co., Ltd., Zhongke Vision Co., Ltd.,Yuncong Technology Co., Ltd., Guangzhou Pixel Co., Ltd., Haixin Kejin Co., Ltd., Shangtang Technology Co., Ltd.in China and so on. They have in-depth cooperation with the public security organs, providing a variety of face recognition products, which makes the power of face recognition in the public security work to the fullest. Through the investigation, this paper sorts out the face recognition products of several face recognition technology companies that cooperate with public security criminal investigation in the market and related products applicable to public security criminal investigation work. 1. The Basic Category of Face Recognition Technology Face recognition technology refers to the technique of comparing and confirming one or more people in an image using an existing face database given a still or moving image. There are three distinct stages in the development of face recognition. Since the beginning of the 1960s, the research work of face recognition has experienced more than 50 years of development, and has became one of the most popular research contents in the field of image analysis and recognition [1], while China's face recognition research started in the 1980s . Although China start late, it has achieved a lot of research results, and some companies and products have reached the world advanced level. In recent years, the rapid development of bio-metrics technology has become a mature means of identification and has received widespread attention. Face recognition, by virtue of its direct, friendly and convenient features, has become the most accepted bio metric method, and has become one of the most active research areas in bio-metrics [2]. With the development of science and technology and the popularity of surveillance, the role of face recognition in public security criminal investigation work has become increasingly important. Through the face recognition to determine the identity of the offenders and conduct search and tracking, the means of inserting the face information into the library to crack other cases have became weapons for the public security organs to crack down the crimes . Therefore, the understanding and investigation of the face 2018 2nd International Conference on Innovations in Economic Management and Social Science (IEMSS 2018) Published by CSP © 2018 the Authors 57 recognition products for public security criminal investigation and their current status is of great significance to the development of public security work [3]. 2. Face Recognition Products and Application Status of Public Security 2.1 Yitu Technology Co., Ltd. and Blink Intelligent Security Platform Shanghai Yitu Network Technology Co., Ltd.'s blinking portrait platform technology is widely used in the public security system's identity screening, synthetic pursuit, detection and resolution, service for people's livelihood and other businesses. Through the system, the public security organs can quickly judge the consistency of the object and the carrying documents, can effectively identify the unidentified objects, and can re-position the bleaching identity personnel by breaking through the limitations of the traditional pursuit means, and can fully depict the working objects. The technology also can provide real-time monitoring and control for important personnel, can help the lost elderly to find family members, can provide verification services for the Internet + police, and can facilitate the masses to ask for help online [4]. At present, Yitu Technology has reached cooperation with the Ministry of Public Security, China Border Inspection, China Marine Police and dozens of public security agencies, and has successfully completed security at major events such as the 2016 Hangzhou G20 Summit and the 2017 BRICS Leaders Summit. It’s work has already unanimously recognized by all parties. 2.2 Kuangshi technology Co., Ltd. and its intelligent security solutions Kuangshi technology corporation’s intelligent security solutions based on face recognition technology, can be widely used in video surveillance, intrusion alarm, access control, access control, electronic patrol, network alarm and other major security areas, which can effectively help government security related agencies, including public security, customs, airports, railways identify suspicious person, certificate real name, set down face electronic fence and accuse key personnel. Its products ,including portrait recognition series (sky system, massive portrait search system), video structured series (video structured engine, structured research and judgment system), pro-detection series (portrait temporary bayonet system, structured service box), vehicle identification system ( vehicle bayonet system and vehicle model evaluation platform) are widely used in three-dimensional security control, intelligent border inspection, intelligent prevention and control, public transportation, temporary deployment control, prison monitoring, military traffic management and vehicle management [5]. In the application scenarios of key places management and control, comprehensive treatment and group stability incidents, portrait bayonet retrofits, camp and perimeter security, three-dimensional prevention and control, etc., Kuangshi Technology ,relying on its high-speed modeling and storage, high-precision identification and second-level response , gains superior performance . 2.3 Shangtang Technology Co., Ltd. and SenseFace face combat platform Shangtang Technology independently develops face static comparison server, face dynamic comparison server, face control actual combat platform, view intelligence research and judgment system, video structured analysis server, identity verification service, face recognition machine (gate machine version), etc. Services and products are gradually establishing close cooperative relations with local public security organs. One of successful case of cooperation is a public security bureau in Guangzhou City use the Shangtang view intelligence research and judgment system. The public security bureau in Guangzhou City use the search function of the map search to compare the face of the crime scene with the standard library photos, conduct the identity check of the personnel, and crack down on the crimes
