verify UI has some issues

[ttbuffey]

Hi,

I noticed a issue in the verify page: previously it's working fine, but inrecent days it shows some issues: like APP used it get the signature name and the AI tools used is a [object,object]. please check below image.

the code I used is

try:
            signer_info = C2paSignerInfo(
                alg=b"ps256",
                sign_cert=cert_chain,
                private_key=private_key,
                ta_url=b"http://timestamp.digicert.com"
            )
            signer = Signer.from_info(signer_info)
        except Exception as e:
            logger.error(f"Error creating signer: {e}")
            raise RuntimeError(f"Error creating signer: {e}") from e
        logger.info(f"signer created in {time.time()} duration {time.time() - starttime}")
        # add source file as an ingredient file.
        builder = Builder(manifest)
c2pa_data = builder.sign_file(signer=signer, source_path=image_path, dest_path=output_path)

the manifest I used is as below

{
    "claim_generator_info": [
            {
                "name": "Analytical Cloud",
                "version": "1.0"
            }
        ],
        "assertions": [
            {

                    "actions": [
                        {
                            "action": "c2pa.created",# asset was first created

                            },
                            "digitalSourceType": "http://cv.iptc.org/newscodes/digitalsourcetype/trainedAlgorithmicMedia",
                        }
                    ]
                }
            },
            {
                "label": "c2pa.training-mining",
                "data": {
                "entries": {
                    "c2pa.ai_generative_training": { "use": "notAllowed" },
                    "c2pa.ai_inference": { "use": "notAllowed" },
                    "c2pa.ai_training": { "use": "notAllowed" },
                    "c2pa.data_mining": { 
                        "use": "constrained",
                        "constraint_info" : "Contact eamail for more information."
                    } 
                }
                }
            }
        ]
}

@ttbuffey Please share the asset you signed (if you can), or a signed test asset that triggers the UI issue in Verify for the AI tool used field.

This is likely an issue with the verify UI (which is not powered by the Python SDK). But I'd need an example of a signed asset to confirm and hand over to someone who can look into this.

In the meantime, you can check if https://contentauthenticity.adobe.com/inspect has the same behavior or not. Thanks.

ps: For the app/device used showing the name in the certificate (I assume that's what is called "signature", in the report?), it may be correct depending on the claim versions you sign. If it's v2 (which is the SDK default now), it would show the information from the signing certificate rather than from the claim generator. This relates to the Conformance efforts.

(You should also switch c2pa.training-mining to use the matching CAWG assertions instead, whose spec is here: https://cawg.io/training-and-data-mining/1.1/)
