Hitachi tested the new technology in house and calculated its authentication accuracy. Specifically, the company verified that the technology correctly authenticates registered people and that it does not authenticate people that have not been registered. The company carried out the former test about 1,000 times and the latter test about 15,000 times, but no error occurred.
"We became confident that we can perform high-accuracy authentication," Hitachi said.
This time, Hitachi did not clarify when to commercialize the new technology, but it said, "We will go forward with the evaluation of the new technology and so forth so that we can commercialize it in one or two years."
For the evaluation results announced this time, Hitachi used VGA images taken by an 8-Mpixel camera. Though the technology was realized with Android, the company plans to support iOS at the time of commercialization.
Also, this time, Hitachi transferred images taken by a smartphone camera to a tablet computer that carries out authentication, which took one second. But the company intends to use a smartphone or a cloud server for authentication at the time of commercialization.
According to Hitachi, smartphone-based personal authentication is also advantageous in terms of cost.
"Currently, one-time passwords are often used for personal authentication at the time of monetary transactions," the company said. "But the technology we developed this time can reduce costs more."
Hitachi will exhibit the new technology at Hitachi Social Innovation Forum 2016 Tokyo, which will take place from Oct 27 and 28, 2016, at Tokyo International Forum.
