Enabling access to data
Methods, systems, apparatus and computer programs for enabling access to data by a requesting party. A plurality of sets of data are generated. A one one-way function is then used to generate a plurality of keys each associated with a respective one of the plurality of sets. Information associated with the data in a given set is used as an input to the one-way function when generating the key for that set. The keys are distributed to requesting parties. Subsequently, a requesting party may make a data access request using the received key. Upon receipt of a key, access may be enabled to the data. The requesting party may then generate validation data from information associated with at least a part of the received data and validating the received data by comparing the validation data to data derived from the received key.
