passport photos for future use. In this manner these surveillance cameras could monitor,
recognise and follow ʹpotential terroristsʹ and other individuals.
3.8 History of Facial Recognition System
The first computer to recognise human faces was developed during 1964 and 1965. The
pioneers of this automated facial recognition system were Woofy Bledsoe, Helen Chan Wolf
and Charles Bisson. An intelligence agency funded this work, but did not allow much
publicity.
The technology works as follows; a large database of images and a photograph, the
problem was to select from the database a small set of records such that one of the image
records matched the photograph. The difficulty with this system was the recognition
problem, because of the “great variability in head rotation and tilt, lighting intensity, angle,
facial expression and aging etcetera. Some other attempts at facial recognition by machine
have allowed for little or no variability in these quantities. Yet the method of correlation [or
pattern matching] of unprocessed optical data, which is often used by some researchers, is
certain to fail in cases where the variability is great. In particular, the correlation is very low
between two pictures of the same person with two different head rotations” [Wikipedia,
May 2007].
3.9 Efficacy and Reliability
Facial recognition is not the most reliable and efficient technique among the different
biometric technologies. Its advantage is that is does not require any aid from the user. If a
system is designed properly it could detect the presence of criminals among crowds. Other
biometric techniques such as fingerprints, iris scans and speech recognition cannot perform
this form of mass scanning. However it is not considered as a very reliable technique and
questions have been raised about the effectiveness of facial recognition software in cases of
railway and airport security.
3.10 Secure Access Road B.V.
Company
Secure Access Road BV [SAR BV] was founded in 2001 and has an office nearby Rotterdam,
in Puttershoek. SAR BV has implemented various biometric bases access systems in several
companies in different branches of industry.
SAR BV is the provider of biometric based access systems. In combination with biometric
technologies they develop several applications which allow the customer to see time and
attendance, customer loyalty and electronic payment. The main links between these
applications are stored on a smart card.
SAR BV has several partners such as Alcazar Pleasure Village and B+P Computersystems.
In 2000 these two parties aimed to develop a biometric access control system for the
catering industry in order to keep out troublemakers.
