Evidence Tamper Detection

How does VIDIZMO tamper detection works? How do you make sure that the evidence has not tampered with? Which algorithm does VIDIZMO use for Tamper Detection?

VIDIZMO uses cryptographic algorithm for tamper detection, when a user uploads certain evidence into the VIDIZMO portal, it goes through an encoding workflow that transcodes the uploaded evidence producing various qualities and renditions for multi-platform playback. At the end of the encoding activity, another process is initiated which downloads all evidence renditions from the storage and generates their original hash to be stored in the database for future reference. Multiple hashes are generated for multiple evidence renditions using the SHA (Secure Hashing Algorithm) Algorithm.
