For instance, a ring signature could be used to provide an anonymous signature from "a high-ranking White House official", without revealing which official signed the message. Ring signatures are right for this application because the anonymity of a ring signature cannot be revoked, and because the group for a ring signature can be improvised.
Ring signature: A similar system that excludes the requirement of a group manager and provides true anonymity for signers (several algorithms nevertheless maintain some "restricting" properties, like traceability or linkability) Threshold signature: A threshold signature involves a fixed-size quorum (threshold) of signers. Each signer must be a ...
Criteria to consider would be whether: (1) the subject has published their own signature; (2) secondary sources have reproduced the signature, with the subject's consent; (3) the image of the signature is from a reliable source, (4) the signature is directly relevant to the article in which it is displayed, and (5) the use of the signature ...

Ruby ring. A ring is a round band, usually made of metal, worn as ornamental jewelry.The term "ring" by itself denotes jewellery worn on the finger; when worn as an ornament elsewhere, the body part is specified within the term, e.g., earrings, neck rings, arm rings, and toe rings.
A signature (/ ˈ s ɪ ɡ n ɪ tʃ ər, ˈ s ɪ ɡ n ə tʃ ər /; from Latin: signare, "to sign") is a depiction of someone's name, nickname, or even a simple "X" or other mark that a person writes on documents as a proof of identity and intent. Signatures are often, but not always, handwritten or stylized. The writer of a signature is a ...
The creators of the Ring-based Learning with Errors (RLWE) basis for cryptography believe that an important feature of these algorithms based on Ring-Learning with Errors is their provable reduction to known hard problems. [8] [9] The signature described below has a provable reduction to the Shortest Vector Problem in an ideal lattice. [10]
