The Next Generation Identification programme will include a nationwide database of criminal faces and other biometrics
"FACE recognition is ’now’," declared Alessandro Acquisti of Carnegie Mellon University in Pittsburgh in a testimony before the US Senate in July.
It certainly seems that way. As part of an update to the national fingerprint database, the FBI has begun rolling out facial recognition to identify criminals.
It will form part of the bureau’s long-awaited, $1 billion Next Generation Identification (NGI) programme, which will also add biometrics such as iris scans, DNA analysis and voice identification to the toolkit. A handful of states began uploading their photos as part of a pilot programme this February and it is expected to be rolled out nationwide by 2014. In addition to scanning mugshots for a match, FBI officials have indicated that they are keen to track a suspect by picking out their face in a crowd.
Another application would be the reverse: images of a person of interest from security cameras or public photos uploaded onto the internet could be compared against a national repository of images held by the FBI. An algorithm would perform an automatic search and return a list of potential hits for an officer to sort through and use as possible leads for an investigation.
Ideally, such technological advancements will allow law enforcement to identify criminals more accurately and lead to quicker arrests. But privacy advocates are worried by the broad scope of the FBI’s plans. They are concerned that people with no criminal record who are caught on camera alongside a person of interest could end up in a federal database, or be subject to unwarranted surveillance.
The FBI’s Jerome Pender told the Senate in July that the searchable photo database used in the pilot studies only includes mugshots of known criminals. But it’s unclear from the NGI’s privacy statement whether that will remain the case once the entire system is up and running or if civilian photos might be added, says attorney Jennifer Lynch of the Electronic Frontier Foundation. The FBI was unable to answer New Scientist’s questions before the magazine went to press.
The FBI hasn’t shared details of the algorithms it is using, but its technology could be very accurate if applied to photographs taken in controlled situations such as passport photos or police shots.

Artists ’have structurally different brains’ 2014 04 17
Artists have structurally different brains compared with non-artists, a study has found.
Participants’ brain scans revealed that artists had increased neural matter in areas relating to fine motor movements and visual imagery.
The research, published in NeuroImage, suggests that an artist’s talent could be innate.
But training and environmental upbringing also play crucial roles in their ability, the authors report.
As in many areas ...
