The Ring Signature pertains to the method of increasing privacy through the fuse of inputs of a number of multiple signers with that of the original ender so as to authorize a transaction.
Produced by cryptographers, Ron Rivest, Adi Shamir, and Yael Tauman, Ring Signatures are used in cryptography. When a transaction is signed with a Ring Signature, it is endorsed by a party from a specific group people.
A Ring Signature could be regarded secured and safe when it is computationally infeasible to tell which among the group members’ keys was used to create the signature.
A Ring Signature is similar to group signatures. It only differs largely from the latter on two counts:
1.Revoking the anonymity of an individual signature is impossible
2.Any group of users can be used as a group without having to use an additional setup
