Personally identifiable information

The legal term for the type of personal data that means an individual can be identified. There is much complexity in the interpretation of what both ‘personal’ and ‘identifiable’ mean, such that some regulators have taken a view that this includes cookies and IP addresses, while others have argued that PII can only exist if there is a ‘real world’ identifier. Seek advice from a legal specialist for the current types of personally identifiable information. See also: Cookie, IP address, Information Commissioner
