How many times have
your smart phone failed to recognize you when you try to use face unlock
system??
University of York researchers have found that face
recognition security can be significantly improved if users store an average
photo of themselves.
Research group led by dr.david Robertson, of department of
psychology’s facevar laboratory at York found that combining several images to
create an average leads to greater recognition rate across a range of daily
settings.
The
researchers examined the performance of the 'face unlock' system on Samsung
Galaxy smart phones.
They chose to study the Samsung Galaxy because it is a very
popular phone which comes with working face recognition technology,"
Researchers found that while the
system was usually consistent in rejecting impostors, it often failed to
recognize the actual smartphone owner.
However,
when researchers morphed several different photos of the user to create an
‘average’, the performance of the facial recognition feature’ significantly
improved, often to perfect levels
The
researchers’ technique is based on studies of human face recognition in which
the brain forms abstract representations of the faces it recognizes, as well as
the fact that humans are typically able to recognize their family and friends
under various conditions.
"We expect this
technique to work across a wide range of
phones and other automated recognition
devices. It is very
interesting that performance can be so much improved by
copying a simple trick performed by the brain.
so to conclude using an average image of yours is the best
way to improve the face recognition security system of
your smartphone.
