LTU-Finder enables advanced image and video search in forensic investigations using Guidance Software's EnCase® .
Hash sets only identify exact matches of images and videos. LTU-Finder works by analyzing the visual features in the image or video to assess its visual content.
With LTU-Finder you can:
- Identify duplicate and modified versions of images,
- Identify scanned documents and screenshots,
- Extract keyframes of video files to quickly summarize content,
- Identify images, videos and folders which may contain pornography, and
- Identify images with faces
LTU-Finder is available for EnCase Forensic or EnCase Enterprise.

Image Matching
LTU-Finder uses LTU "image DNA" to identify duplicate and modified images. Instead of using a hash code, which will only identify exact matches, the image DNA will identify matches as well as modified versions of an image. Using image DNA, LTU-Finder will find matches to images that have undergone common manipulations such as resizing, color changes, file type changes, the addition of text or slight crops and rotations.
LTU-Finder can search for image matches from a set of local reference images, or from a dataset generated by another LTU-Finder user or by Image-Seeker server.

Image and Video Classification
LTU-Finder can classify some of the images and videos found within EnCase. For example, LTU-Finder highlights those folders which contain pornography, images of scanned documents, and images which contain faces.
This technology works by comparing images against an image profile which defines a category of images. For example, LTU's pornography profile has been trained on more than 30K pornographic images.
