Comparative Study
Among the different biometric techniques, facial recognition may not be the most reliable and efficient. However, one key advantage is that it does not require aid (or consent) from the test subject. Properly designed systems installed in airports, multiplexes, and other public places can identify individuals among the crowd. Other biometrics like fingerprints, iris scans, and speech recognition cannot perform this kind of mass identification. However, questions have been raised on the effectiveness of facial recognition software in cases of railway and airport security.

Famous quotes containing the words comparative and/or study:
“If you believe that a nation is really better off which achieves for a comparative few, those who are capable of attaining it, high culture, ease, opportunity, and that these few from their enlightenment should give what they consider best to those less favored, then you naturally belong to the Republican Party. But if you believe that people must struggle slowly to the light for themselves, then it seems to me that you are a Democrat.”
—Eleanor Roosevelt (1884–1962)
“Oh, London is a man’s town, there’s power in the air;
And Paris is a woman’s town, with flowers in her hair;
And it’s sweet to dream in Venice, and it’s great to study Rome;
But when it comes to living, there is no place like home.”
—Henry Van Dyke (1852–1933)
