Eye Twitch Patterns as a Biometric
A biometric security system based on how a user moves their eyes is being developed by technologists in Finland. Writing in the International Journal of Biometrics, the team explains how a person's saccades, their tiny, but rapid, involuntary eye movements, can be measured using a video camera. The pattern of saccades is as unique as an iris or fingerprint scan but easier to record and so could provide an alternative secure biometric identification technology.
Martti Juhola of the University of Tampere and colleagues point out that fingerprint and face recognition are perhaps the most usual biometric means to verify identity for secure access to buildings and computer resources and even at international borders. Other techniques such as iris scanning are also occasionally used in some circumstances. The most obvious disadvantage of such biometrics is that they might be forged through the use of an image or prosthetic.
