Ring signatures are similar to group signatures but differ in two key ways: first, there is no way to revoke the anonymity of an individual signature; and second, any set of users can be used as a signing set without additional setup.

Even though both are group-oriented and protect user anonymity, group and ring signatures differ in several ways. For instance, although both schemes provide user anonymity, group signature schemes have revocable user anonymity, and ring signatures have non-revocable user anonymity.

Threshold signatures are digital signatures where signers can establish groups such that only certain subsets of the group can produce signatures on behalf of the group. The collection of subsets that are authorized to produce signatures is called the access structure of a threshold scheme.

Multisignature: A multisignature represents a certain number of signers signing a given message. Number of signers is not fixed and signers identities are evident from a given multi-signature. A multisignature is much shorter (sometimes constant) than the simple collection of individual signatures.

In the context of Monero, ring signatures are used to sign transactions. More specifically, you can think of coins with different amounts having public keys, which can be used to authorize spending them. With a ring signature, you can hide which coin you're actually spending, by dissimulating it among many others.

A ring signature enables an individual of a group to sign a message on behalf of the group without revealing the identity of the real signer. It is useful in the application of leaking authoritative secrets in an anonymous way.
