Artificial Intelligence（AI） is making it possible for companies to monitor workers' behavior in great detail and in real time.Start to slack off（懈?。?，and AI could talk to your boss.
   One company offering such services is Londonbased startup Status Today.Its AI platform relies on a regular supply of employee data，including everything from the files you access to when you use a key card.From this，it builds a picture of how employees normally function and signals any unusual performance.The idea is to spot when someone might become a security risk by doing something different from their usual behavioral patterns."All of this gives us fingerprint of a user，so if we think the fingerprint doesn't match，we raise a warning，"says Mircea Dumitrescu，the company's chief technology officer.
   The system also aims to catch employee actions that could accidentally cause a security breach（漏洞），like opening malware（惡意軟件）．"We're not monitoring if your computer has a virus." says Dumitrescu."We're monitoring human behaviors."
   But catching the security breach means monitoring everyone，and the AI can also be used to track employee productivity."It seems like they are just using the reputation of AI to give an air of lawfulness to oldfashioned workplace surveillance（監(jiān)視），" says Javier Ruiz Diaz of digital campaigning organization the Open Rights Group."You have a right to privacy and you shouldn't be expected to give that up at work."
   Exactly how companies use the system will be up to them，but it's hard to shake the picture of an AI constantly looking over employees' shoulders."It will bother people，and that could be counterproductive if it affects their behavior，" says Paul Bemal at the University of East Anglia.
   Phil Legg at the University of the West of England says it will never catch every security risk."If people know they're being monitored，they can change their behavior，" he says.
