Attendees: Wenjing Chu (FutureWei), Angel Li (W3C), 蒋晓黎(寰宇信任),赵峰,赵鹏,杨学轶,沈慧海(华为),郑黎方(寰宇信任),罗夏朴(港理工)
1. Wenjing Chu, C2PA以及如何与DID/VC分布式认证联系起来
赵鹏: C2PA能否防止盗用?例如去除C2PA信息,然后盗用,再发布。Wenjing Chu:不行,无法防止盗用,只能检查真实性。
赵鹏: 关注针对3D模型的C2PA的发展
罗夏朴:照相机需要有私钥来做签名,可能会带来安全隐患。Wenjing Chu:现在相机还未使用,需要安全硬件。
蒋晓黎:C2PA是否有详细的标准?Wenjing Chu:W3C有个标准,也有不少具体实现。
蒋晓黎:公钥管理,CA还是区块链;Wenjing Chu:都可以。
郑黎方:如何验证公钥匙属于某个用户的;Wenjing Chu & Angel Li: DID https://www.w3.org/TR/did-core 把身份和设备关联在一起。Verifiable
credential
https://www.w3.org/TR/2022/WD-vc-data-integrity-20221110/ https://www.w3.org/TR/2022/WD-vc-data-model-2.0-20220811/

2. 蒋晓黎: 视频,数字资产的确权,认证
赵鹏:数字资产是元宇宙的核心资产;数字版权管理的保护和管理能力元宇宙中的数字资产同样需要;数字资产生产即确权,follow C2PA来演进,利用数字指纹/水印来确权;数字资产在线授权;数字资产收益自动结算;数字资产在线维权。Chu:
数字资产如3D模型的格式,如何利用DID。
赵鹏:数字资产的保护。媒体在浏览器基于EME保护,3D模型在浏览器上是否有对应的保护?Wenjing Chu: 加密可能总会被绕过,新技术需要依靠历史来维权;身份是核心。
