In simple terms, Signum Technologies' innovative VeriData data validation technology is designed to guarantee the integrity of digital data from the point of acquisition right through to final end use.

VeriData ensures that if a data file which has been validated by the VeriData process is subsequently modified in any way, that modification will be detectable and highlighted by the VeriData detector software.

VeriData is designed for use where visual or audio records are captured as digital data and which may be required to stand up to judicial or ethical scrutiny. Applications for VeriData embrace scenes-of-crime recording, law-enforcement, accident investigation, surveillance, security monitoring, smart-card systems, document management, medical imaging, scientific research and critical component testing.

The sophisticated VeriData algorithm has been specifically designed for incorporation into software programs, typically used in secure imaging workstations, or alternatively, embedded into hardware devices, such as digital cameras.

In either application, digital image, video or sound records are safeguarded by being encoded with a unique and highly secure signature which prevents the VeriData validation from being undone by an unauthorised party.

For users who need the highest level of data authentication, an enhanced version of VeriData will also allow users to embed encoded provenance information such as date, time, location, serial number, etc. into their digital records.
