Does technology offer peace of mind?

TWO PEOPLE IN NINGBO, East China's Zhejiang province, were reported to have stolen a roommate's money from his bank account by unlocking his smartphone via facial recognition while he was asleep. Science writer Zhang Tiankan comments:

The local police have already solved the case. According to their analysis, the facial recognition of the victim's smartphone had a major flaw: it can function even when the owner's eyes are closed, which is uncommon for the facial recognition software of smartphones.

The case sends a warning about facial recognition technology, which has many flaws and deficiencies that are yet to be solved. The shape of a human face varies with the changes in light and observation angle. Wearing glasses, shaving, or a different hair cut, all these can result in the failure of human face recognition technology.
