Features are disclosed for the validation of an image and the verification of the validation of a validated image. A computing device can receive a request to validate an image. The computing device can validate the image and generate a validated image. The computing device may embed a signed token in the validated image. The signed token may include a digital certificate associated with a publisher of the image, a hash of a portion of the image, and metadata associated with the image. The computing device may store the hash of the portion of the image on a blockchain and provide the validated image. A client computing device may verify the validation of the validated image using the digital certificate, the hash of the portion of the image stored in the signed token, the hash of the portion of the image stored on the blockchain, and the metadata.
