Co.

artificial intelligence identifies if the person seeking access is
authorized.

not a panacea, has a lot of strengths that other authentication methods
don’t."
百度首席科学家Andrew Ng告诉CNNMoney，“面部识别虽然不是灵丹妙药，但是有很多其他身份验证方法没有的优势。”
Using biometrics for authorization is nothing new. Fingerprint scanners
have long been used, but they aren’t always effective.
