Indirect Identifier

Indirect Identifier:

An indirect identifier is a value which cannot be used to identify an individual on its own, but could be identifying if combined with other indirect identifiers. Indirect identifiers are similar to quasi-identifiers, however some organizations, including Eurostat and Privitar, distinguish between the two on the basis of how likely it is that the value could be used to re-identify an individual. For example, date of birth and postcode would be considered quasi-identifiers, as they are quite likely to be known by others and so could be used in a linkage attack. Whereas a value not widely known, for instance an internally generated value like a payment plan category, might be considered an indirect identifier.
