Hong Kong's Customs and Excise Department has planned to study the introduction of artificial intelligence to its computer forensic lab - a system that aims to improve efficiency in analysing evidence. It would help the department in tackling crimes linked to digital evidence.
A report by South China Morning Post (SCMP) mentioned that the system can process hours of surveillance camera footage or about 6,000 images within seconds.
As quoted in the report, Wong Wai-kei, who is a senior inspector of the computer forensic lab, said: "In the past, our approach involved a colleague sitting in front of a screen for an hour to watch a one-hour closed-circuit television footage."

"With the use of an AI system, we only need to input relevant commands, conduct a search, and potentially process the case in just a few seconds," Wong added.
The inspector said that the officials can process a case in a "matter of seconds" after entering several relevant commands for a particular search after the implementation of the AI system.
As quoted in the report, Chiu Kat Wu-lan, who is an acting assistant staff officer in the department, said that it was not immediately clear when customs would incorporate the AI system into its daily operations.

She said that the customs was "proactively exploring the use of new technologies" in order to better its potential to handle digital evidence and help it combat tech crimes.
Chiu claimed that the rise in cybercrimes has complicated their forensic work. The crimes include the development of smartphone technology and the frequency of infringement actions on auction platforms.
"In the era of big data, the computer forensic laboratory also started to handle cases such as money laundering and smuggling, in addition to infringement and dangerous drugs," Chiu, who specialises in computer forensic and information technology security, said as quoted.
"The amount and complexity of digital data processed by the computer forensic laboratory have skyrocketed, posing a considerable challenge to the laboratory’s work," she added.
Chiu said that the AI system would not replace officers. But is the system reliable? As per the report, Francis Fong Po-kiu, honorary president of the Hong Kong Information Technology Federation, said that the quality of outcomes can't be guaranteed despite the fact that AI is much faster. He added that the department would need to have the knowledge to validate materials generated by AI for better quality.
