Twins crack face recognition puzzle

The computer whiz-kids — 22-year-old identical twins, Michael and Alex Bronstein, almost impossible to tell apart — have applied a new technology to recognizing faces in a way that may yet revolutionize international security.

“I said it to them as a joke: if you succeed in building a system that can distinguish between the two of you, you’ll get (a grade of) 100,” said the twins’ professor, Ron Kimmel of the Technion Institute in Haifa. “They succeeded and got 100. They are brilliant.”

The technology scans and maps the human face as a three-dimensional surface, providing a far more accurate reference for identifying a person than current systems, most of which rely on two-dimensional images, Kimmel said.
