Gretak says Parabon’s technology “does not tell you the exact number of millimeters between the eyes or the ratio between the eyes, nose and mouth.” Without that kind of accuracy, facial recognition algorithms may not give accurate results પરંતુ but to obtain such accurate measurements from DNA would require fundamentally new scientific discoveries, she says, and “papers trying to predict at that level do not have much success.” Gretak says that parabons only predict the normal shape of one’s face (although the scientific possibility of such a prediction has also been questioned).
Police are known for conducting forensic sketches based on witness descriptions through facial recognition systems. A 2019 study by the Georgetown Law Center on Privacy and Technology found that at least half a dozen police agencies in the U.S. allow for facial recognition systems as input photos, using hand-drawn or computer-generated forensic sketches, if encouraged. If not “. AI experts warn that such a process could lead to lower levels of accuracy.
According to a slide deck presentation available online, Corsite has 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 for the most challenging situations.” In a technology demo for IPVM last November, Corsight CEO Watts stated that Corsight’s face recognition system “recognizes anyone with a face mask – not just a face mask, but a ski mask.” IPVM reports that using Corsight’s AI on a masked face has gained 65% confidence, Corsight has its own measure of how likely it is that the captured face will match its database, and notes that the mask is more accurate as a balclava or neck. As described. Gator, just opposite the ski mask with mouth and eye cutouts.
Extensive issues with the accuracy of face recognition technology have been well documented (by MIT Technology Review). This is especially evident when photographs are poorly lit or taken at extreme angles, and when the skin of the subjects is dark, feminine, or too old or too young. Privacy advocates and people have also criticized facial recognition technology, especially systems like Clearview AI that scratch social media as part of their matching engine.
The use of technology law enforcement is particularly prevalent – Boston, Minneapolis and San Francisco are among the many cities that have banned it. Amazon and Microsoft have stopped selling facial recognition products to police groups, and IBM has removed its facial recognition software from the market.
Albert Fox Kane, a civil rights lawyer and executive director, says, “The idea that you’ll be able to create something with the granularity and level of loyalty required to run a face match search – for me, is absurd.” Surveillance Technology Oversight Project, which works extensively on issues related to facial recognition systems. “It’s pseudoscience.”
Dezimila Cerro, a researcher at the Centrum Viscunde and Informatica’s Computational Imaging Group, a national research institute for mathematics and computer science in the Netherlands, says the science supporting such a system is not yet developed, at least not in public. Cerro says the list of genes needed for accurate facial depiction from DNA samples is currently incomplete, citing a 2017 study of human longevity.
In addition, factors such as the environment and aging have a significant effect on the face that cannot be captured by DNA phenotyping, and research has shown that individual genes do not affect a person’s facial appearance based on their gender or ethnicity. “Premature attempts to implement this technique will potentially undermine trust and support for genomic research and will not bring any social benefits,” she told MIT Technology Review in an email.
