Proventsure develops software to search computers for sensitive and confidential information based on algorithms used by molecular biologists to map DNA, as well as many custom developed algorithms for decoding files and data to ID information and clustering file owners. Some of this research has applications in other areas, as is the case with PhotoSeek. This application is useful for law enforcement personal since it can identify similar photos, without the need for cryptographic file hashes, which are very frequently inaccurate at detecting image files. Images are easy to change without visible detection to the human eye, yet completely defeat file hash detection mechanisms.
PhotoSeek can identify similar images, even when they've been resized, compressed, or changed to other formats like bmp, jpg, and gif.
