Discuss ISCC (new ISO standard) and how it might fit here
🎥 4'46": Discuss #113: Consider how to reference ISCC in identity assertion or somewhere in C2PA ecosystem.
🎥 8'41": Olaf gave a brief overview of ISCC as it was introduced in ISO meetings last week.
The ISCC standard is a global content identifier that describes content in visual and binary hash terms.
Lindsay, Olaf and Eric discussed a perceptual hash alternative to cryptographic hash. Lindsay explained that the ISCC code combines four things, including perceptual hash for the actual image, metadata hash, data similarity score, and interesting tools.
Nigel pointed out that there are many different fields in the data, ranging from high-level descriptive letter down to hard hashing.
The following links were shared in the chat during this discussion:
ACTION: No concrete proposal at this time. Eric to discuss with Leonard as to whether this is a better fit for C2PA or CAWG.
Journalist and editorial impact
🎥 14'56": Review Notes from call two weeks ago
Truman and Lindsay discussed the readout from the journalist and editorial impact meeting held a couple of weeks ago. The high-level takeaway was the need for privacy and contextualization in creator assertions. They discussed challenges in maintaining trust across different contexts and industries. They will be working with Patrick to schedule follow-up meetings in the next few weeks.
Move to approve endorsement assertion specification
🎥 18'55": MOTION: As per Community Specification License process §4: Specification development process, I move to promote the Endorsement Assertion from draft to approved (version 1.0 final) status:
4.2. Draft. Each Pre-Draft document of a Working Group must first be Approved to become a “Draft Specification.” Once the Working Group approves a document as a Draft Specification, the Draft Specification becomes the basis for all going forward work on that specification.
4.3. Working Group Approval. Once a Working Group believes it has achieved the objectives for its specification as described in the Scope, it will Approve that Draft Specification and progress it to “Approved Specification” status.
ACTION: Eric to reach out to Charlie Halford of BBC for final review and approval. Group approves this specification, conditional on approval from Charlie.
Review open identity assertion PRs
Discussion on the following PRs:
🎥 19'45": #103: Add optional protections against unexpected claim and unexpected claim generators
Eric and Nigel discussed expected countersigners and the inclusion of referenced assertions in identity assertions. They agreed to include the naked reference claim structure in the final claim box instead of zeroing out the representation of other identity assertions. Eric proposed modifying the definition of expected countersigners to include the signer payload.
ACTION (✅): Eric to merge #103.
ACTION (✅): Eric to close #96 without merging.
ACTION (#114): Eric to revise definition of expected_countersigners
to include a copy of signer_payload
from other identity assertions. Expect PR for this next week.
🎥 34'44": #107: Revise Overview section to include new trust signal diagrams
Eric discussed two new diagrams that were added per a suggestion from last week, giving a visualisation of the identity assertion structure and how that compares to the C2PA Manifest structure.
ACTION (✅): Eric to merge #107.
🎥 37'09": #98: Introduce an optional signer_payload.role
field.
Eric discussed one change made since previous review, which was to allow multiple roles to be specified.
Group discussed the values that could be accepted for signer_payload.role
and agreed to continue the current strategy of a fairly simple built-in list of roles. There was a general discomfort with the “reviewer” role as insufficiently specified, so we agreed to delete it. A variant of this may be introduced later.
ACTION (✅): Eric to delete the cawg.reviewer
role.
ACTION (✅): Eric to merge #98.
A new 1.0-draft version of the identity assertion has been published with the above changes merged.
Heads up on training and data mining assertion
🎥 48'40": Expecting some feedback in next week or two that may lead to requested revisions to the Training and Data Mining Assertion. If you have concerns or questions, this would be a good time to raise them.
European Identity Conference invitation
🎥 49'24": If you’ll be at EIC 2024 next week, please say hi. I’ll be making three presentations or panel discussions during the conference.
Next week’s CAWG meeting will proceed as normal. I’ll have arrived in Berlin in time to host the meeting. |
Before the recording started, some of us discussed the Mobile Ecosystem Forum Connects ID & Data 2024 conference, organized by Michael Becker and in which Eric was a presenter. |
