Disclosed is a method of storing information concerning an entity, the method comprising the steps executed by computing means of receiving information concerning an entity; receiving (with or separately to the information concerning an entity) an identifier of the entity which the information concerns; causing key preparation computing means to prepare a key dependent on the identifier of the entity using an irreversible computational procedure; and storing, in first data storage means, relatably to the key prepared by the key preparation computing means, some or all of the received information concerning the entity, but not including any information identifying the entity. There is also disclosed a method of transferring data related to an entity and identifying information identifying the entity, the method comprising the steps of ensuring that the data does not include said identifying information, and is hence anonymous, but does include a key, the key being relatable to identifying information identifying the entity to which the data relates by privacy control computing means; receiving the anonymous data at a recipient computing means; before, during or after said receiving, determining whether the recipient computing means or a user thereof is authorised to match the data to the identifying information and, if so, exchanging the key and the identifying information between the privacy control computing means and the recipient computing means separately from said data; thereby enabling the recipient computing means to match the anonymous data and the identifying information identifying said entity. |
