Section 1 of the Data Protection Act contains the main definitions which are to be used in its interpretation.

This section sets out the key definitions in the Act, explains what they mean, and shows how they often relate to each other.



** Public authorities specified in the Freedom of Information Act 2015 should note that the definition of "data" has been extended to include "unstructured data".

This change impacts on compliance with the Act, the data protection principles and the rights of individuals, in particular the extension of the right of access to personal data. **
