UnverifiedSigning, auditing, and hash pinning must be used in combination; none of the three can be omitted.65% similarUnverifiedOne approach to resolving legitimate editing boundaries is hash commitment with selective disclosure: signing only the original RAW data, declaring standard processing through a predefined list of permitted transformations, and replaying the transformation chain for verification.58% similarUnverified哈希链保证的是内容一致性而非身份认证,Merkle 树设计目标是完整性验证而非不可伪造性,后者需要非对称密码学58% similarUnverifiedThe capability of citation anchors has a clear upper limit: text matching can only prove that the characters exist in the document, it cannot prove that those characters are the correct source of the field, nor can it capture misreadings by OCR itself.56% similarUnverifiedAER-1 specifies what to capture, how to hash inputs and outputs, how receipts are chained, and how third parties can complete verification using only the records and a hash function; it remains a draft rather than a final standard and already has implementations in multiple languages.55% similar
