You
don't need to bring a ticket of any kind of identification, get your hand stamped or flash a driver's license
for admission to one tourist destination in China. All visitors need is
something they can't lose — their face.
Baidu, a Chinese tech company, began
testing facial recognition technology last week in Wuzhen, a historic town with
classic canals and architecture.
The area receives millions of visitors each
year. The technology has shortened wait
times and added convenience for guests. So far feedback has been positive,
according to Baidu (BIDU, Tech30) and the Wuzhen Tourism Co.
When a visitor arrives, their photo
is taken and uploaded to a database as seen above. When he or she attempts to
access certain parts of the town, a tablet attached to the entry gates records
video.
It then send a few frames to the cloud, where
artificial intelligence identifies if the person seeking access is authorized.
This all happens in 0.6 of a second, according to Baidu. The technology is
accurate 99.77% of the time.
You always
have your face with you," Baidu chief scientist Andrew Ng told CNNMoney.
"Facial recognition, while not a panacea, has a lot of strengths that other
authentication methods don't." Meanwhile, some iris-scanning technology
can be tricked by printing out a photo of a human eye.
Baidu's technology, however,
detects when a person isn't live so someone can't beat the system. Baidu isn't
the only company using a person's face for authentication. Microsoft lets users
sign into some of its Surface tablets with facial recognition technology.
