Securly Unveils Nudity Detection Feature Led By Screen Scanning AI

Share Article

Securly has added a new screen scanning feature to its Filter product that detects nudity without the need for text indicators.

Securly, the Silicon Valley-based student safety company, is excited to announce an upcoming enhancement, named Screenscan, to the company's flagship Filter product that enables advanced nudity detection by using imagine-analysis AI on screenshots of web pages. Screenscan is a supplement to Pagescan, Securly’s proprietary technology that is used in Filter. Previously, Pagescan required text to scan for nudity. With Screenscan, Filter can now flag and block access to foreign-language porn websites, as well as sites with nudity that contain ambiguous or limited textual context.

Securly launched its cloud-based web filtering product, Filter, in 2013 in the K-12 market for school districts to use to achieve CIPA compliance by blocking porn, gambling, and proxy sites. Filter has so far used Pagescan technology to detect and block nudity online by automatically detecting new pornographic sites and adding them to an internal database. Once added, students will be blocked from accessing that site from their school devices. In order to detect these websites, Pagescan technology would primarily scan the text on the website to determine the pornographic and inappropriate nature of the site. Pagescan uses AI to run statistical models of what text on pornographic sites look like and compares that to the unknown site. Using this approach, Pagescan was excellent at detecting porn sites featuring English text. However, escort sites, where images clearly indicated inappropriate content but the text would be relatively vague, or non-English porn sites with foreign-language text or little to no text at all would be more challenging for Pagescan to detect and flag. In addition, sites with a minimal level of nudity, making them age-inappropriate for K-12 students, could also pose a challenge to a pure text-based approach.

Now, with Screenscan, Pagescan has the capability to detect nudity using screenshots of the website. Not only does this allow for the detection of non-English porn sites, image-heavy porn sites, and escort sites, this allows Pagescan to assess these websites using a process that is closer to the experience of the human brain - where adult content is identified visually first. This significant extension of Pagescan will allow Securly to provide more comprehensive filtering for nudity and porn on school-issued devices, and ensure students in schools are enjoying a safer, more protected online experience.

“Pagescan was built to allow Securly to perform AI-based text-classification of websites in the cloud. Today, Screenscan extends that technology to AI-based image-classification of websites, again 100% in the cloud, and allows the millions of iPads, Chromebooks, Windows, and Mac devices that Securly serves to instantly benefit from a single unknown website being flagged by our Screenscan technology,” said Vinay Mahadik, co-founder and CEO.

This enhancement reinforces Securly’s commitment to its mission of enhancing and protecting students’ digital experiences.
