The fifth and final stage is a declaration of matches based on the strength of the sco res generated from the comparison (Woodward et al. 8) Security of biometric facial recognition Despite the many benefits associated with the use of this engineering science there are also some risks pertaining to its use. Like any other technology requiring the use of the internet for data transmission, privacy is a major concern.
