Prudentina dual creates software to combat pedophilia – Globo.com

In seeking to assist in the fight against pornography, one of Presidente Prudente pair developed a software capable of identifying the origin of photographs found on computers and mobile people who commit this crime. Danillo Roberto Pereira, professor and doctor, and Guilherme Fernandes Sekine, bachelor in computer science, started the project in early 2014, however, due to a problem with their computer, which meant that all content was deleted, the system can only be used from now on.

According to Pereira, it all started in 2013, after seeing a similar research in a lab where he worked, but it was very complex, which sparked interest in creating something easy to understand. “Along with William, who was my student at the time, we decided to start this work. The tool can identify, through the pixels of which machine it was taken. That’s because, however good the camera is, there will always be a clearer point or darker than the others, “he explains.

The comparison is made through” calculations, “says the professor. “The system makes a comparison of pedophilia photography, with images posted by the author in social networks, for example. Thus, it analyzes and can point out if the photos were taken by the same device. “

This search tool help punish those who produce illegal content to children. “When you are a pedophile, he often claim that the images on their computers have been obtained by other means, saying it is only a user because the crime for anyone who uses the images is lower than for those who do. It is not always possible to prove the authorship of pictures. Now this system gives to point the author, as a ballistics examination “, he said.

The aim of the double, as the teacher and doctor, is available, free of charge, to the police and other people can use the software. “Our intention is to patent the idea, so that it is not copied. However, let you free, so that the tool is for public use, “says.

Even ready to use, Pereira claims will meet with Sekine to know when to put the system on the network. “After the problem we had were about three months until we get it. Now we need to look at how do we make it accessible, “he concludes.
