henkilöllisyyskriteerit

Henkilöllisyyskriteerit refers to the criteria used to define and verify an individual's identity. These criteria are fundamental in various social, legal, and administrative contexts to ensure that a person is who they claim to be. In a broad sense, personal identity is a complex interplay of physical characteristics, personal history, social roles, and self-perception.

Legally, personal identity is often established through official documentation. Examples include passports, driver's licenses, and national identification cards. These documents typically contain a unique identifier, such as a personal identification number, along with biographical information like name, date of birth, and place of birth. Biometric data, such as fingerprints, facial features, or iris patterns, is increasingly used as a supplementary or primary means of identification due to its inherent uniqueness to an individual.

In everyday life, identity is also shaped by a person's name, relationships, memories, and experiences. Social identity, for instance, is derived from group affiliations, cultural background, and societal roles. Psychologically, personal identity is tied to a continuous sense of self over time, encompassing beliefs, values, and personality traits. Understanding and applying personal identity criteria are crucial for security, trust, and the functioning of society.
