Patent ID: 11822375

Abstract:
A method at a controller (112) of a database network (110) is provided. The controller (112) receives (S100) a request for a first set of data entries (200a). The request comprises a public identifier and an identifier of a first database (111a) of the plurality of databases (111) from which the first set of data entries (200a) is to be retrieved, each data entry (210) in the first set of data entries (200a) comprising a respective raw value for each of a plurality of attributes (220). The controller (112) retrieves the first set of data entries (200a) and uses the public identifier to transform (S120) the raw values of at least a first attribute (220a) of the plurality of attributes (220) into respective synthetic values. The controller (112) generates (S130) and outputs (S140) a first dataset (300a) comprising data entries having the synthetic values for the first attribute (220a) and the raw values for at least one of the attributes (220).
