DNA fingerprinting is a technology that analyzes an individual's DNA to help law enforcement departments quickly and accurately identify suspects. This approach has proved its worth over time.
However, privacy and data accuracy remain major issues with facial recognition technology. Furthermore, its usage raises many ethical concerns, specifically its application for facial image collection.
Predictive policing
Predictive policing uses data collected by police departments to identify crime hot spots and target areas with high crime rates but low reporting to law enforcement. Predictive algorithms also help predict which individuals are most likely to commit criminal acts; all with the goal of reducing violent crime by targeting communities most at risk; however, critics have raised objections that such practices are unjust and biased.
Facial recognition technology uses various parameters to accurately recognize individuals. For instance, it compares captured images against databases of facial profiles, using parameters like eye distance and forehead-chin distance as criteria for identity verification and paternity testing. Corsight has created a facial-matching tool which uses DNA samples with person photos or videos; its software detects movement and voice. They plan to commercially release their technology this year.
India recently passed the Criminal Procedure Identification Act which permits police to collect DNA samples and face-matching measurements from anyone charged or suspected of criminal behavior. The National Crime Records Bureau serves as the central organization responsible for rolling out these new measures at 1,300 police stations as well as for creating standard operating procedures to record these measurements.
Real-time crime detection
Law enforcement officials can use DNA and face-matching systems as an invaluable asset, and their popularity is steadily growing as technology becomes more widely accessible. These tools enable law enforcement officers to rapidly identify people in real time for police investigations or private sector companies looking for suspects or victims; but these technologies also raise serious privacy and civil rights concerns, particularly since it can be utilized without prior consent of those being studied; it has even been employed to track individuals who refuse to cooperate with authorities, prompting fears it might be misused against innocent parties.
Police departments frequently employ face recognition software, yet it's essential for officers to assess its accuracy before using it in the field. Software could miss features that distinguish each individual and match them incorrectly with others resulting in false positives that lead to officers stopping innocent individuals or wrongly detaining them.
To combat this issue, software can be configured to exclude certain characteristics - for instance, eye, nose, and mouth shapes - as well as limit matches to just a single individual; this will improve accuracy while decreasing false positives.
Corsight AI claims to have developed a system that can identify people based on their DNA samples. The technology employs this DNA sample as part of an algorithm which compares facial features against a database of images to find potential matches for identification; however, experts have criticized its efficacy as scientifically untenable.
Identifying crime spots
Facial recognition technology often produces many false matches due to incomplete and inconsistent facial data derived from different lighting conditions or camera resolution. Therefore, police must set a high confidence threshold so as to avoid reporting false matches as this reduces misidentification risk but limits crime hot spot identification capabilities.
This system compares a photograph of an individual to his or her DNA profile to identify their ideal match, and then uses a face-to-DNA classifier to verify their identity. These classifiers were trained on a validation dataset with genuine and impostor instances labeled; finally fusing these classifiers together produced one overall matching score for identification analyses.
Corsight AI claims to have created an AI system which combines facial recognition and DNA profiling in order to accurately identify people by their genetic traits, however this approach is deemed scientifically unfeasible by experts.
India's Criminal Procedure Identification Act empowers central investigating agencies to collect physical and biological samples such as retina and iris scans of those arrested by law enforcement, replacing the 100-year-old Identification of Prisoners Act which permitted police officers to capture fingerprint impressions under court order. The National Crime Records Bureau is charged with carrying out this measure.
Identifying suspects
DNA fingerprinting has long been a useful tool for police officers, but using computers to recreate suspect faces could prove even more effective in uncovering crimes. This technology, known as DNA facial mapping, has raised some privacy issues among advocates who fear that it could lead to racial profiling or violate individuals' rights; however, its effectivity remains uncertain.
Genetic detectives can currently accurately predict an individual's eye and hair colors; however, they do not yet have the technology necessary to create an accurate face image of their suspect. Scientists are working on this, however; eventually their technology could enable the ability to accurately discern features like freckling, baldness, hair curliness and tooth shape in addition to age prediction.
One company, Corsight, claims it has created a system to identify faces from DNA samples. Their CEO and VP presented the system at an investors conference in New York last month in a presentation given by CEO and VP Yaniv Erlich from genealogy site MyHeritage who provided an alternative view by writing an extensive response that detailed major flaws with Corsight's technology.
