WSQ is well-suited for preserving the very high resolution fingerprint images while achieving high compression ratios of typically 12:1 to 15:1

A typical fingerprint card results in approximately 10 megabytes of scanned bitmap data, thanks to our WSQ implementation this can be massively reduced to less than 1megabyte in size. The FBI's Integrated Automated Fingerprint Identification System (IAFIS) is part of a project to design and implement a national standard for the collecting, encoding storing, and retrieving digitized fingerprint images. It is a requirement that fingerprints submitted to the FBI conform to their strict standards. Most lossy compression methods, such as JPEG, discard the smallest (highest frequency) details in images, and at these higher compression ratios unacceptable distortions are introduced into the image. Contained within fingerprints are tiny details that are considered admissible points of identification in a court of law. Compressing a fingerprint image using JPEG may remove these fine details regarding them as noise, blocking artefact's may also be introduced at compression ratios above 10:1.
