There has always been a lot of controversy around all kinds of biometric technology, especially face recognition which is relatively new to the field.
However, for instance, most of Australians seem to accept the usage of biometrics by the police, as The Sydney Morning Herald reports. The study shows that 61 percent of Australians assume biometrics serve a great purpose of ensuring public safety. Almost half of the interviewed, 49 percent, expressed some concern of the technology usage being an invasion of privacy. Yet they do not mind it as long as data storage and use is transparent.
In some other parts of the world, citizens would happily hand in their biometric data if that meant quicker processing. As Korea JoongAng Daily mentions, Koreans prefer to line up and check-in for flights using palm vein technology to reduce human contact and make the boarding process faster.
