Abstract: This invention relates to a scheme for storage of private information on a cloud computing platform without contravention of territorial privacy laws. A method of anonymising a database of personal data is described whereby data identifiers are assigned to data items and deviation identifiers are assigned to deviations for selected data items derived from reference records. Such information can then be uploaded to a cloud based storage platform. A translation table maps the data items, data identifiers and deviation identifiers to the original data entries. This translation table is stored locally and separate to the anonymised information uploaded to the cloud. The invention further describes a method of decoding the database anonymised according to the above method.
