Proposed Definition

  1. One of multiple attributes that together identifies an entity in context.


See note for identifier and distinguish from unique-identifier. Example: A common example of using multiple attributes to identify an entity is asking for name and address. Given the size of the overall population, most individuals will have names that they share with other people. Adding the address to the name enables differentiation and much higher confidence that a unique person has been identified. Different combinations of common attributes result in different levels of confidence in the uniqueness of the resulting identity.
