New Observation of the Year of the Tiger ｜ Alarm algorithm has increased Xinxiang's procuratorial "Hui Eye" mana greatly

Henan Daily client reporter Ren Na Correspondent Mao Pei Zhang Fang

"Personnel gathering alarms!" Recently, the real -time alarm function of the unusual behavior analysis system of the Xinxiang Procuratorate of Henan Province, Henan Provincial Procuratorate of the Procuratorate of Henan Province, was on the red light. The scope of the fighting behavior once again won a "digital empowerment" supervision and cooperation battle.

In 2018, the Supreme Procuratorate deployed the reform of the inspection of the inspection. As a pilot unit of Henan, Xinxiang explored the patrol procuratorial model. How to improve the depth and accuracy of supervision under the premise of ensuring the breadth of supervision? Xinxiang City Procuratorate decided to "combat effectiveness" from big data, and developed "anomaly analysis systems for supervision venues", making it a "wisdom eye" that is deeply penetrated into the large wall.

Treating the "small earthquake" of regulatory venues

"This is the clothes sent by the family." In the regulatory place in Xinxiang City, the police took the initiative to raise the items in their hands and presented in front of the camera. In recent years, it has been shown in front of the camera in front of the camera, which has become the "conventional action" of the police of the regulatory venue of Xinxiang City.

At the end of 2018, in response to the call for the construction of the Supreme Procuratorate Smart Inspection, the Xinxiang City Procuratorate started to develop an abnormal behavior analysis system. On the basis of the video data of 6 prisons and 9 detention centers in the jurisdiction, Xinxiang City Detention Center was piloted. Once abnormal behavior analysis systems, once abnormal behavior in the regulatory area, the system will automatically alert prompts.

"Personalized alarm!" In August 2019, the Xinxiang City Procuratorate conducted a patrol inspection of the county's detention center. The abnormal behavioral analysis system captured the picture of three law enforcement officials in the data imported data. After further investigation and verification, it was found that many law enforcement officers in the detention center had violations of laws and regulations. In the end, six personnel, including the director of the detention center, were held accountable.

A stone staged the thousands of waves. This once "inconspicuous" analysis system has triggered a "small earthquake" in the regulatory venue of Xinxiang City.

"Since we have an abnormal behavioral analysis system, we have paid attention to regulating our own behavior." According to the police's report, although there have been video surveillance, some irregular law enforcement behaviors have been easily drowned in massive video data. The anomalous behavior analysis system can automatically identify, intelligent analysis and judgment on massive data, such as retention timeout, abnormal contact, personnel gathering, and personnel fall to the ground. fish".

The "Motivation of Motivation" that can not be stunned

After a long time, what should I do if the key video evidence is damaged? How to win the "opportunity" for the investigation? How to reduce the misunderstanding rate of the system alarm?

If the road is long, the line will come. Facing the difficulties and blockages encountered in the application of actual case handling, the Xinxiang City Procuratorate focuses on the problem -oriented and continuously improves the system model. On the one hand, it enhances the "brain power" of the analysis system. In the context of business logic Expand the scenarios of intelligent identification to 13 to make the analysis system more intelligent; on the other hand, enhance the "eye force" of the analysis system. The accuracy rate is further improved to make the analysis system more accurate.

"The biggest feature of the upgraded analysis system is to increase the simultaneous review function." According to the prosecutor, the Xinxiang City Procuratorate was added to 48 roads based on the original 16 videos of the city detention center. Realize synchronous real -time censorship.

"Monitoring room leaving the police!" In January 2021, the abnormal behavior analysis platform turned on the red light. The prosecutor looked at the video in real time and found that there was no one -time duty in the women's monitoring room in the detention center. Immediately, the prosecutor notified the situation to the detention center, and the detention center sent hands that day to regulate the duty behavior.

People will be stunned, and the machine will not. After having a synchronous real -time censorship function, once there is an abnormal behavior, the analysis system can be monitored as soon as possible, and automatically intercepted the video video of key frames and 15 seconds before and after, screening and identifying abnormal violations of regulations and disciplinary abnormal behaviors, and pushed to the prosecutor in real time.

"Fighting power" to big data

In 2021, the Xinxiang City Procuratorate conducted a inspection inspection of the county's detention center. After receiving the reaction clues of the detainer, the prosecutor introduced the video introduction system review system of nearly 15,000 minutes during the key period, and found that the detainees were fighting each other. In the subsequent investigation, the prosecutor also touched the vine and found that the county's public security bureaus existing 11 major categories 11 issues were finally held accountable.

With the empowerment of procuratorial big data, Xinxiang Criminal Implementation Prosecutor's Supervision, Integration, and Investigation was optimized under the combination of review, investigation, and investigation.

"With this platform, the supervision is more accurate, and the combat effectiveness is greatly improved." According to the prosecutor, according to regulations, the inspection prosecution needs to view the video within 3 months. The month can't be seen, but through an abnormal behavioral analysis system, artificial intelligence and big data technology can be used to identify the alarm. It can automatically generate review results in less than half a day. Not only can the prosecutors "get away" from a large amount of video information, but also improve the accuracy of supervision.

The efficiency is improved, the clues have been more, and the success rate has also increased.Since 2021, the analogy of anomalous behavior analysis system in the supervision venue has been monitored in real time, and the anomalies of illegal violations of discipline and disciplinary abnormal behaviors were used to introduce more than 10,000 hours, analyzed 2472 analysis alarms, screening and identifying the supervisory police officer's violations of disciplinary abnormal behaviors 27 timesEssence"Prosecutor's big data strategy, empowering the high -quality development of procuratorial work in the new era, and solving the pain points and difficulties that the traditional supervision methods are difficult to solve." According to Wu Yan, deputy prosecutor of Xinxiang City Procuratorate, the abnormal behavior analysis system developed by the institute is inBased on the video module, it is actively exploring the voice module and upgraded to an abnormal behavior analysis system that "see+hear", and then builds an analysis of abnormal behavior analysis, "online prosecutor", duty crime investigation and judgmentIntelligent review and remote contract of mining of torture and parole cases, the criminal implementation of the procuratorial holographic perception system that integrates the system in one to achieve the "digital revolution" drives the overall quality improvement of legal supervision of the new era.
