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

Tag Suggestio

ns

Uses face recognition software to suggest peoples names to tag in pictures without their permission

Page 19: Sit powerpoint

Question for discussion:Do you think the tagging feature is perceived as

a positive or negative feature to most of the cyber community?

Page 20: Sit powerpoint

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

Page 21: Sit powerpoint

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”
