"Despite its core role in the EU system of data protection, the meaning of identification remains unclear" @Nadya_Purtova aims to clarify the "legal meaning of identification under the GDPR" by providing a "socio-technical typology of identification":

@Nadya_Purtova "In addition to the established [identification] types, I will identify targeting as a new identification type, where to identify by way of targeting means to select a particular individual from a group as an object of attention or treatment in a single moment of time"
Building on existing socio-technical accounts of identification, the typology distinguishes five identification types:
(i) look-up or civil identity identification where persistent identifiers such as a name, passport or social security number, a phone number or address link to a person in a real world
(ii) recognition identification where a person is recognized as known from a previous interaction by a token or another persistent identifier that does not connect to the real-world civil identity
(iii) session identification where a person is reached or linked to an identifier of a limited lifetime for a duration of one interaction
(iv) classification identification where a person is identified as a member of a certain existing group or category by displaying characteristics of that group or category
(v) targeting ... ie selecting in a single moment of time a particular individual from a group as an object of attention or treatment, which can be done either on the basis of a single unique identifier which does not have to be persistent, or on the basis of a rich dataset ...
