This document proposes a machine-readable Hypertext Transfer Protocol (HTTP) response header field, AI-Disclosure , to disclose the presence and degree of Artificial Intelligence (AI) generated or AI-assisted content in web responses. The header is designed for compatibility with HTTP structured field syntax and provides metadata for user agents, bots, and archiving systems. It supports layered disclosure strategies alongside human-readable and structured metadata formats.| www.ietf.org
The BBS Signatures scheme defined in , describes a multi-message digital signature, that supports selectively disclosing the messages through unlinkable presentations, built using zero-knowledge proofs. Each BBS proof reveals no information other than the signed messages that the Prover chooses to disclose in that specific instance. As such, the Verifier (i.e., the recipient) of the BBS proof, may not be able to track those presentations over time. Although in many applications this is desira...| www.ietf.org
This document defines an extension to the BBS Signature scheme that supports blind digital signatures, i.e., signatures over messages not known to the Signer.| www.ietf.org
BLS is a digital signature scheme with aggregation properties. Given set of signatures (signature_1, ..., signature_n) anyone can produce an aggregated signature. Aggregation can also be done on secret keys and public keys. Furthermore, the BLS signature scheme is deterministic, non-malleable, and efficient. Its simplicity and cryptographic properties allows it to be useful in a variety of use-cases, specifically when minimal storage space or bandwidth are required.| www.ietf.org
