Ann Cavoukian, Ontario's Information and Privacy Commissioner writes about facial recognition and privacy in today's Globe and Mail.
"Your facial image and identity are your personal information. Being unique in nature, this biometric identifier can represent you in the digital world, and may be misused, lost or stolen, leading to potential matching, tracking, impersonation and other deceptive practices. Accordingly, there are significant privacy and security challenges to facial recognition that must be overcome to ensure that any “unanticipated” negative effects are avoided. Beware of unintended consequences!
The most serious is the linkage of your biometric template across multiple databases, for uses that were never intended. One’s identity may now be routinely shared online by others, as well as one’s personal profile and geo-location data. When facial recognition becomes widespread, your biometric template could be used to identify you in multiple databases."
