Hong Kong AI application for early detection of suicides or fights in prison

Tram Ho

Hong Kong technology company Wildfaces is seeking to detect cases of suicidal intentions or prison scandals in AI. Since then, the government and private enterprises have applied AI to build a smart industrial city.
Using AI-integrated cameras, Wildfaces developed an image analysis system for the city's Correctional Department to detect suspicious behavior in a large number of prisoners, including self-destructive or self-destructive. fight.

Ivy Li, founder and executive of Wildfaces said that because of the lack of behavioral databases, Wildfaces is forced to skip the "machine learning" step and go into behavioral baseline analysis to detect signs of potential negative behaviors.

The system will conduct a comparison and analysis of suspicious behavior through fully automated cameras without human intervention, such as a prisoner gathering or a prisoner standing by a window with a rope , or bang your head against the wall. In this case, the system will signal to the supervisor that there is a danger for them to intervene.

In February, more than 40 integrated AI cameras were installed in the prison of Pik Uk, a small prison in Sai Kung district, Hong Kong. This is part of a "smart prison" project and many other prisons are expected to be installed in the future.

The company also establishes facial recognition technology in fitness courts or workstations so that it can use technology to monitor and manage large numbers of prisoners at a distance.

The smart prison project was initiated in the policy of building a smart city of Ms. Lam Trinh Nguyet Nga, head of Hong Kong Special Zone in October last year to equip law enforcement officers with technological equipment to help Increase work efficiency.

Companies and community organizations in Hong Kong are accelerating the application of artificial intelligence to the government's encouragement to create an international smart city in the mobile and life sectors. , environment, public services and other areas.

According to figures from the Bureau of Corrections, in 2018, Hong Kong prisons have two cases of suicide deaths, 48 ​​cases of self-injury and a total of 483 fights, including among prisoners. and between the prisoner and the prisoner.

Compared to other countries, Li was impressed by how the Hong Kong government considered security and protected prisoners against the dangers of fighting.

“I have participated in many smart prison projects around the world, but Hong Kong is the only project that cares deeply about the safety and protection of prisoners. We have never received a request to monitor self-destructive behavior elsewhere. ” "Most other projects focus heavily on monitoring fights and fleeing," Li said .

In addition to smart prisons, Wildfaces also implements AI technology to help maintain the metro system by detecting unusual activities of equipment that operate regularly such as escalators or elevators.

Wildfaces is betting on the development of artificial intelligence analyzing images. In addition to video surveillance, the number of cameras is increasing thanks to their presence on mobile devices such as smartphones, glasses, drones … so we can create real-time network of identification and monitoring without too many machines.

In Hong Kong, AI technology is growing but the city government still thinks quite "pragmatically" on this issue, Li said. "In Hong Kong, we need to prove that our technology is cost-effective, not simply applying it to this or that . "
