• The AI cameras that spot shoplifters before they lift

  It is watching, and knows a crime is about to take place before it happens.

  Vaak, a Japanese start-up, has developed artificial intelligence (AI) software that hunts for potential shoplifters, using footage from security cameras for fidgeting, restlessness and other potentially suspicious body language.

  While AI is usually envisioned as a smart personal assistant or self-driving car, it turns out the technology is pretty good at spotting nefarious behavior. Like a scene out of the movie Minority Report, algorithms analyze security camera footage and alert staff about potential thieves via a smartphone app.

  The goal is prevention; if the target is approached and asked if they need help, there is a good chance the theft never happens.

  Vaak last year made headlines when it helped to nab a shoplifter at a convenience store in Yokohama. Vaak had set up its software in the shop as a test case, which picked up on previously undetected shoplifting activity. The perpetrator was arrested a few days later.

  CRIME-FIGHTING AI

  “I thought then: ‘Ah, at last!’” Vaak founder Ryo Tanaka, 30, said. “We took an important step closer to a society where crime can be prevented with AI.”

  Shoplifting cost the global retail industry about US$34 billion in lost sales in 2017 — the biggest source of shrinkage, according to a report from Tyco Retail Solutions. While that amounts to about 2 percent of revenue, it can make a huge difference in an industry known for razor-thin margins.

  The opportunity is huge.

  Retailers are projected to invest US$200 billion in new technology this year, according to Gartner Inc, as they become more open to embracing technology to meet consumer needs, as well as improve bottom lines.

  “If we go into many retailers whether in the US or UK, there are very often going to be CCTV cameras or some form of cameras within the store operation,” Gartner retail analyst Thomas O’Connor said. “That’s being leveraged by linking it to an analytics tool, which can then do the actual analysis in a more efficient and effective way.”

  Because it involves security, retailers have asked AI software suppliers, such as Vaak and London-based Third Eye not to disclose their use of the anti-shoplifting systems.

  However, it is safe to assume that several big-name store chains in Japan have deployed the technology in some form or another.

  Vaak has met with or been approached by the biggest publicly traded convenience store and drugstore chains in Japan, Tanaka said.

  Big retailers have already been adopting AI technology to help them do business. Apart from inventory management, delivery optimization and other enterprise needs, AI algorithms run customer-support chatbots on Web sites. Image and video analysis is also being deployed, such as Amazon.com Inc’s Echo Look, which gives users fashion advice.

  “We’re still just discovering all the market potential,” Tanaka said. “We want to keep expanding the scope of the company.”

  Founded in 2017, Vaak is testing in a few dozen stores in the Tokyo area. The company this month began selling a market-ready version of its shoplifting-detection software, and is aiming to be in 100,000 stores across Japan in three years.

  It has ￥50 million (US$450,000) in funding from SoftBank Group Corp’s AI fund, and is in the middle of its series A round, seeking to raise ￥1 billion.

  What makes AI-based shoplifting detection a straightforward proposition is that most of the hardware — security cameras — is usually already in place.

  “Essentially this is using something that’s been underutilized for decades,” Third Eye business development manager Vera Merkatz said.

  Founded in 2016, the start-up offers services similar to Vaak in the UK market, where it has a deal with a major grocery chain. Third Eye is looking to expand into Europe.

  The ability to detect and analyze unusual human behavior also has other applications.

  Vaak is developing a video-based self-checkout system, and wants to use the videos to collect information on how consumers interact with items in the store to help shops display products more effectively.

  Beyond retail, Tanaka envisions using the video software in public spaces and train platforms to detect suspicious behavior or suicide jumpers.

  At Third Eye, Merkatz said she has been approached by security management companies looking to leverage their AI technology.

  “The potential is broad, since it can be applied outside of shoplifting prevention and outside of retail — such as with manufacturing or other types of marketing,” said Hiroaki Ando, a retail consultant at Ernst & Young Advisory & Consulting Co in Tokyo.
