Law-Enforcement and Evidential Imaging

Growth in the use of digital imaging in law-enforcement is rapid as new technologies - digital cameras, CCTV surveillance, high-bandwidth transmission - provide new and effective capabilities in the pursuit of criminals. Difficulties occur in the presentation of digital evidence in court in proving that no changes to such evidence have been made prior to its presentation.

Signum's VeriData technology provides a unique solution to the problem of data authentication, enabling in the case of digital images, subsequent modifications to be checked down to pixel level.

Where appropriate, VeriData Plus, an enhanced version of VeriData can be used such that original images can be watermarked with relevant data - date/time, capture device, location, event, etc. - and authenticated.

VeriData therefore provides a powerful solution to ensure that evidential material is clearly identified and confirmed as original material.
