Public-sector organizations responsible for critical infrastructure and community safety face significant pressure. They must protect people, maintain public trust, and respond transparently, often with limited budgets that do not keep pace with emerging threats.  

For these organizations, the stakes are high. Manipulated or disputed video can cause operational confusion, inflame communities, undermine prosecutions, damage reputations, create legal risks, and erode confidence in public safety institutions.  

SWEAR believes the ability to verify authenticity should be accessible to every organization, not only those with large budgets. That commitment led to the creation of the SWEAR Cities Program, a tailored initiative designed to bring video authentication to the public-sector organizations that need it most.  SWEAR works by establishing an independent chain of custody for digital evidence, ensuring authenticity from the moment of capture through export and investigative processes and into legal proceedings. SWEAR’s approach is unique in that it provides verifiable proof that a recording matches its original cryptographic record.  

It begins working the moment a camera records, generating cryptographic fingerprints for each frame. These fingerprints are stored separately and anchored to a global blockchain network. The original footage remains private and unchanged, while only the proof data is secured remotely.  

That separation is the critical point. A manipulated video can imitate a scene. It can even look perfect to the human eye, but it cannot rewrite the independent record that was created when the original was created. Any copy of the footage can later be verified against the original fingerprints. SWEAR detects any changes, even at the pixel or audio segment level. Successful verification provides tamper-evident proof that the footage remains unaltered since capture.  

This solution offers more than improved storage or access logs. It provides independent, cryptographic evidence of integrity — delivering the proof leaders need when recordings are challenged publicly, during investigations, or in court.
