Automatic Pornography Detection in Photos and Videos
The Forensic Studio Ultimate edition of Belkasoft Evidence Center comes with the ability to automatically detect human faces and pornographic content in still images and video files. The ability to automatically find pornography in multimedia files such as pictures and videos is a signature feature of Forensic Studio Ultimate compared to Standard and Professional editions. With Belkasoft Evidence Center Ultimate, forensic specialists can find pornography in pictures and video files in a fully automated way.
Extracting Key Images from Video Files
When scanning the disk, the tool will automatically create a list of still images and video files with pornographic content, and will turn lengthy videos into snapshot galleries of still images by extracting key frames, helping forensic specialists to speed up the investigation a great deal by quickly glancing over detected evidence instead of spending time reviewing each of the many video files. In addition, Forensic Studio Ultimate can discover scanned or photographed documents by detecting the presence of text in the images.

Detecting Pornographic Content in Images and Video Files
Belkasoft Evidence Center employs a neural network algorithm to detect human faces and find pornographic content. While it is not yet possible to create a 100% perfect algorithm, we come very close to detecting most pornographic images and video files captured in reasonable lighting conditions with very few false positives and extremely small change of missed evidence. At the time of the writing, the chance of missing a file containing evidence during automatic porn detection is 4.96%, while the chance of a false positive (reporting pornographic content on a file without it) is about 16.31%.
Please note that any of the following conditions will reduce the chance of successful porn detection:
- Poor lighting conditions and night vision devices
- No or little skin tones appearing in the image
- Heavy post-processing, special effects, monochrome or black-and-white conversion
To help forensic specialists discover more evidence, Belkasoft Evidence Center assigns a scoring factor to each image or video file. Evidence can be sorted by that score factor by clicking the Porn probability column. The most suspicious images will appear in the beginning of the list.
Note: key frame extraction must be performed first before detecting pornography in video files.
Detecting Scanned Text in Pictures and Images
Finding images containing scanned or photographed documents is yet another ability of Belkasoft Evidence Center. By activating image-specific analysis, investigators can automatically locate pictures, photos and images containing scanned documents and photographed text. This feature is often used by corporate security specialists, helping to prevent or investigate information leaks and security breaches.
