Description
TL;DR: A focused survey of blind signatures: how a signer can authorize a message without learning the message being signed.
About This Document
The paper discusses blindness, unforgeability, unframeability, and several variants of blind-signature schemes. Its practical examples center on electronic coins and electronic voting, where authentication is required without exposing the user’s underlying message or identity relationship.
Why Bitcoin People May Care
Blind signatures are foundational digital-cash history. Bitcoin does not use Chaumian blind signatures in its base protocol, but the privacy problem they address—and their influence on later electronic-money systems—makes this a useful piece of the pre-Bitcoin cryptography shelf.
