NetClean ProActive:
two new exiting developments PhotoDNA searches and NetClean Web Console

The latest NetClean ProActive release (19.1.0) includes two new exciting developments. The first is the possibility to do manual, scheduled or on-incident searches, using robust hashing technique PhotoDNA. This makes it possible to detect more files than previously. The second development is a new web-console, which is the first step towards a modern web-based management interface.

Widening the search with PhotoDNA

To make NetClean ProActive even more efficient at finding child sexual abuse material (CSAM), we are adding more methods to identify CSAM, that will complement the NetClean hash. Adding PhotoDNA for scheduled and manual searches is the first step in this development. It has previously been possible to do PhotoDNA scans on nearby files after an incident, but the development widens the possibility to detect more files.

What is PhotoDNA?

PhotoDNA is a so-called robust hashing technique. Like the NetClean hashes, PhotoDNA only detects images that have been classified as CSAM by law enforcement. PhotoDNA can detect images that have been very slightly altered e.g. changed to a different filetype, scaled to a different size or changed from colour to black and white. This widens the search field and the number of images that the software now can detect. The reason why PhotoDNA is not used in all searches has to do with performance.

A new web-console

The new web-console is the first step towards a web-based management interface, aimed at making the management and handling of the NetClean ProActive installation easier and more flexible. In this first version the web-console is a dashboard where the user can, for example, see the number of active agents and which version the system is running on. We will continue to add functionality to this with the aim to introduce a full-scale web-based management console.
