Abstract
Disclosed is improved technology for authenticating electronic images and storing proof of tampering or non-tampering on the blockchain. An image authentication application of a user device may generate an image. The user device may generate an image hash of the image using a hash function. The image hash may be written to the blockchain. This may occur immediately after the image has been taken. The user device may upload the image to an authentication server, which authenticates the image. At various times, such as after receipt, during authentication, and/or after authentication, the authentication server may generate an image hash of the image using the hash function. The authentication server may write the image hash(es) to the blockchain. As such, a state of the image at various times may be recorded on the blockchain to determine whether or not the image has been tampered with between various times.
