Parabon’s technology “can’t tell you the exact millimeters between the eyes or the proportions of the eyes, nose and mouth,” Gretak said.Without that level of precision, facial recognition algorithms can’t provide precise results, but getting such precise measurements from DNA requires entirely new scientific discoveries, she said, and “papers trying to make predictions at this level have not achieved Too much success. Greytak says Parabon can only predict the approximate shape of a face (although The scientific feasibility of such predictions has also been questioned).
Police have been known to draw forensic sketches based on witness descriptions through facial recognition systems.One Georgetown Privacy and Technology Law Center 2019 Research It was found that at least six police departments in the U.S. “allow, if not encouraged,” to use hand-drawn or computer-generated forensic sketches as input photos for facial recognition systems.AI experts warn that such a process is likely resulting in reduced accuracy.
Corsight has also been criticized in the past for exaggerating the capabilities and accuracy of its facial recognition system, which it calls “the most ethical facial recognition system in very harsh conditions,” the slide shows. Presentations available online. in a IPVM Technology Demonstration In November, Corsight CEO Watts said that Corsight’s facial recognition system can “identify people wearing masks, not just masks but ski goggles.” The IPVM reports that running Corsight’s facial recognition system on a masked face The AI produces a 65 percent confidence score, which Corsight itself measures how likely a captured face is to match in its database, noting that the mask is more accurately described as a balaclava or neck. Leggings instead of a ski mask with only mouth and eye cutouts.
Broader Issues Related to the Accuracy of Facial Recognition Technology OK–record on file (including MIT Technology Review). They are more noticeable when the photo is poorly lit or taken at extreme angles, and when the subject is dark-skinned, female, very old or very young.Privacy advocates and the public have also criticized facial recognition technology, especially systems like this one AI clear view They crawl social media as part of their matching engine.
The use of technology by law enforcement is especially difficult — Boston, Minneapolis and San Francisco are among many cities that have banned the use of technology. Amazon and Microsoft have stopped selling facial recognition products to law enforcement agencies, and IBM has pulled its facial recognition software from the market.
“fake-science”
“The idea that you’re going to be able to create something with the level of granularity and fidelity you need to perform face matching is nonsense, in my opinion,” said Albert Fox Cahn, a civil rights attorney and executive director of surveillance technology at the Oversight Project, Broad Research issues related to facial recognition systems. “This is pseudoscience. »
Dzemila Sero, Researcher Computational Imaging Group Centrum Wiskunde & Informatica, from the Netherlands’ national institute for mathematics and computer science, claim that the science behind such a system is not fully developed, at least not yet publicly. Citing a 2017 study of human longevity, Sero said the catalog of genes needed to generate accurate facial representations from DNA samples is currently incomplete.
In addition, factors such as environment and aging have a significant impact on faces that are not captured by DNA phenotypes, and studies have shown that individual genes have as much influence on facial appearance as gender and ancestry. “Premature attempts to implement this technology could undermine trust and support for genomics research and provide no societal benefit,” she told MIT Technology Review in an email.
