Parabon’s technology “does not tell you the exact number of millimeters between eyes or the ratio between eyes, nose and mouth,” Greytak says. Without this kind of precision, facial recognition algorithms can’t deliver accurate results—but getting such precise measurements from DNA would require fundamentally new scientific discoveries, and “articles trying to predict at this level didn’t have much information success.” Greytak says Parabon only predicts the general shape of someone’s face (though The scientific feasibility of such an estimate has also been questioned.).
Police are known to make forensic sketches based on witness statements through facial recognition systems. A 2019 research from Georgetown Law’s Center for Privacy and Technology It found that at least half a dozen police agencies in the United States “allow, if not encourage,” the use of hand-drawn or computer-generated forensic sketches as entry photos for facial recognition systems. AI experts have warned that such a process is likely. leads to lower levels of accuracy.
Corsight has also been criticized in the past for overestimating the capabilities and accuracy of its facial recognition system, which according to a deck of slides it calls “the most ethical facial recognition system for extremely demanding conditions.” presentation available online. In Technology demo for IPVM Last November, Corsight CEO Watts said that Corsight’s facial recognition system could “identify someone by a facemask (not just a facemask, but also a ski mask)”. IPVM reported that using Corsight’s artificial intelligence on a masked percentage generated a confidence score of 65%, noting that Corsight’s own measure of the probability that the captured face matched in its database, and that the mask was more accurately identified as wool or neck. leggings, unlike a ski mask, which only has mouth and eye openings.
Broader issues with the accuracy of facial recognition technology, well–documented (including MIT Technology Review). These are more noticeable when photos are poorly lit or taken at extreme angles, and when subjects are darker skinned, female, or very old or very young. Privacy advocates and the public have criticized facial recognition technology, particularly systems like the one below. Clearview AI those scraping social media as part of the matching engine.
The use of the technology by law enforcement is particularly worrying—Boston, Minneapolis, and San Francisco are among the many cities that have banned it. Amazon and Microsoft stopped selling facial recognition products to police groups, and IBM removed facial recognition software from the market.
“fake science”
“The level of granularity required to run a face match search and the idea that you can create something with fidelity is mind-boggling to me,” says civil rights attorney and CEO Albert Fox Cahn. Surveillance Technology Surveillance Project, which works extensively on issues related to facial recognition systems. “This is pseudoscience.”
Dzemila Sero, researcher Computational Display Group The science to support such a system is not yet developed enough, at least not publicly, says Centrum Wiskunde & Informatica, the Dutch national research institute for mathematics and computer science. Citing Human Longevity’s 2017 study, Sero says the gene catalog needed to produce accurate depictions of faces from DNA samples is currently lacking.
Additionally, factors such as environment and aging have significant effects on faces that cannot be captured by DNA phenotyping, and research has shown that individual genes do not affect the appearance of a face as much as their sex and ancestry. “Early attempts to apply this technique will likely undermine trust and support for genomic research and yield no societal benefit,” he told MIT Technology Review in an email.
