Digital security: who takes care of data from facial recognition cameras? A facial recognition system integrated into the state database began to be used in Porto Alegre to help locate missing people. The technology is synchronized with electronic fence cameras and generates automatic alerts when it identifies someone registered as missing. In one of the cases, a person who had been missing for more than 15 years was located by the city hall. According to the secretary, the technology can compare current images with old records of missing people. Her identity has not been released. "We now have an aging system. So, we have already found people 15 years old after their disappearance. The AI ??looked for similarity, aged that person and matched it and we were able to approach it," he said. ? Access the g1 RS channel on WhatsApp Notices are received at the Integrated Coordination Center of the City of Porto Alegre, the CEIC-POA, located in the Azenha neighborhood. After that, the incident is directed to the security forces, who go to the location where the person was identified. According to Porto Alegre's municipal security secretary, Alexandre Aragon, the system began to be tested in January and was expanded in April. Currently, 25 cameras are enabled for facial recognition in the city. In the last 30 days alone, according to him, 93 alerts were recorded. "Facial recognition was once a very difficult thing, but today your cell phone has facial recognition. And why not use this to help people on the street too?", said the secretary. The referral depends on the situation identified in the incident. When the person located is a child or teenager, they are taken to the responsible agency. In these cases, referral occurs even when the child or adolescent is accompanied by a family member, if there is a record of the disappearance. In cases involving adults, the procedure is different. If the person located says that they do not want to be found, this manifestation is recorded on video and forwarded to the Civil Police so that the disappearance record can be removed. "Often the person wants to disappear. They fought with their family, but we take footage of the person saying they don't want to be found, send it to the Civil Police's missing person section and the person is discharged," he said. The secretary also highlighted that integration between security agencies has been expanded. In addition to the Metropolitan Civil Guard, the Military Brigade and the Civil Police began to receive alerts in real time and share information. The Military Brigade also began to operate within the CEIC. According to Aragon, the system's accuracy has increased since testing began. In January, according to the secretary, the rate was between 50% and 70%. Now, he claims that the technology works with accuracy between 96% and 99%. The secretary also said that the city hall is talking to municipalities in the Metropolitan Region to expand integration between facial recognition systems. The intention, according to him, is to form a "belt" in Greater Porto Alegre with cities that already use the technology. Aragon stated that other steps are being studied. One of them is integration with fugitive databases. Another involves the use of technology in cases related to domestic violence.
