A method of providing to an individual (28) selected personal data (136) relating to an entity (26) is described. The method comprises: encrypting a plurality of fields (132) of personal data, each data field being encrypted with a unique cryptographic key; storing each of the encrypted data fields (134) in a data record (130) at a central location such as a data storage service provided by an Internet Service Provider; and supplying a specific cryptographic decryption key associated with a respective one of the unique cryptographic keys which relates to a selected field (132) of the entity's personal data to the individual, such that the individual is only able to decrypt the selected field of the entity's personal data by accessing the stored data record (130).
