“the ability of a computer to scan, store, and recognize human faces for use in identifying people.”
Biometrics“Biometrics consists of methods for uniquely
recognizing humans based upon one or more intrinsic physical or behavioral traits.”
Examples of biometric systems are:
• Signature• Finger Prints• Voice• Iris

Geometry• Ear
Geometry• Face
The History of Face Recognition
1964-1965 1970 1973 1988 1991 2001“Connectionist”
Face Recognition first captured the public’s attention
Bledsoe, Wolf, and Bison created the first semi-automated system Goldstein, Harmon, and Lesk use markers to automate the recognition
Fisher and Elshlagerb take a face template and map it onto a global template
Connectionist Approach: uses gestures and identifying markers Kirby and Sirovich pioneered the eigenface
approachTurk and Pentland enabled a reliable real-time automated face recognition system

Benefits1. Checks for criminal
records2. Enhances security by
using surveillance cameras
3. Finding lost children from public cameras
4. Know in advance if a VIP is entering
5. Detection of a criminal at a certain place
6. Pattern recognition7. Used in science to
compare an entity with a set of entities
Question?Name something face recognition is used in our
generation today.
“Once the stuff of science fiction and high-tech crime fighting, facial recognition technology has become one of the newest tools in marketing, even though privacy concerns abound”

Type of person advertising
Tag Suggestio
ns
Uses face recognition software to suggest peoples names to tag in pictures without their permission
Question for discussion:Do you think the tagging feature is perceived as
a positive or negative feature to most of the cyber community?
Facebook and Facial Recognition
“First we added group tagging, so you could type one name and apply it to multiple photos of the same person. Now we're announcing tag suggestions, which will make tagging multiple photos even more convenient” - Facebook
Carnegie-Mellon Facebook study
Facial Recognition in the future could used to..• Identify strangers• Get social security numbers• Gain personal information
Tests performed:-On campus identification via collected
facebook pictures- Dating site profiles matched to faceook
profiles
Goal: "that it is possible to start from an anonymous face in the street, and end up with very sensitive information about that person." The results were "made possible by the convergence of face recognition, social networks, data mining and cloud computing - that [is referred] to as augmented reality."
Facial Recognition Major Risk: Privacy
Handing stalkers their material
“and its new face-recognition feature could become the latest example of a seemingly innocuous development morphing into a serious threat to the privacy of our (visual) data.” “Awesome! Now I can take pictures
of cute girls at the grocery store or at the park, upload them and Facebook will tell me who they are!
Facebook had 60 billion pictures in 2010
“researchers from Carnegie Mellon University recently proved that Facebook's vast photo archive can be used to identify people on the street. Yes, in real life. Yes, we can totally use Facebook's archive to identify people in real life, from photos on the web”
Cloud Based Facial Recognition

Questions
1) What application has Google consistently used face recognition on since 2009?Picasa
2) This local place has same kind of photo database as Facebook and some of them have wisely incorporated facial recognition technology to prevent identity theft (and identity creation)…Your local
DMV
3.) When was face recognition introduced to the world?
