Forward anonymity is a concept related to privacy and data protection, particularly within the context of cryptographic systems and communication protocols. It refers to the ability of a system to ensure that past communications or transactions remain private even if a user's current identity is later compromised. In a system exhibiting forward anonymity, if an adversary were to learn a user's current identity or key, they should not be able to retroactively determine the identities or details of past interactions.
