Security is still weak Although face recognition technology has evolved


Face recognition technology has emerged as a means of authentication for Smartphones following fingerprint and iris recognition technology. Face recognition technology has become more sophisticated, but the problem is that facial information is as well known to others as to the users.

Apple’s recently released iPhone X has a face recognition feature.

Lee Hana/iPhone X user:  “I bought iPhone X because I wanted to take advantage of features that change my emoticon face through face recognition technology.”

Apple’s 3D camera accurately analyzes faces and even allows financial transactions.


South Korean businesses such as Samsung also use face recognition technology for a variety of electronic devices.

When tens of thousands of dots measure up to the height of the face, artificial intelligence improves accuracy through constant learning.

[Kim Jung-bae / Alchera inc. CEO: Even if the user wears sunglasses or disguises, face recognition technology uses different parts of the face to unlock the entire face because it registered the entire face during the initial registration process, and AI continues to learn.]

However, facial information has a fundamental weakness.

The problem is that it’s always exposed, unlike fingerprints, iris, or intravenous information.

Anyone can collect and exploit information on other people’s faces whenever and wherever they want.

Lim Jong-in/Professor of the Graduate School of Information Security at Korea University: There are now a lot of security cameras. It is exposing a lot of facial information without consent. There is also considerable concern that the user’s face may be used for purposes other than those specified.]

In addition, even if foreign companies like Apple keep their customers’ facial information, they cannot be restricted by domestic law yet.
Some point out that it is too early to conduct financial transactions with face recognition.
