senderrecipient

In information technology, senderrecipient is a term used to describe the two parties involved in a message exchange: the sender and the recipient. The term is commonly used when discussing message routing, access control, auditing, and data schemas that model communication as a paired relationship rather than a one-way entity.

In data formats and network protocols, senderrecipient may refer to a combined field or object that stores identifiers for both participants. Some systems keep separate fields for sender and recipient, while others expose a consolidated view for easier logging or analytics. A composite representation can simplify middleware routing logic and allow unified handling of message metadata.

Common representations include separate fields such as sender and recipient (e.g., JSON: { "sender": "alice", "recipient": "bob" }), or a single encoded string such as 'alice|bob' or 'alice->bob' used by legacy systems. The choice affects validation, access control, and privacy considerations.

Security considerations emphasize authenticating the sender and ensuring the recipient is authorized to receive the content. Logging should preserve the senderrecipient context for audits while protecting sensitive addresses. In privacy-focused systems, access to recipient data may be restricted or masked.
