US 8,788,679 B2 · Method for exchanging data

Abstract

The present invention relates to a method for exchanging data between at least two servers with use of a gateway. Preferably the method is applied to healthcare systems. Each server holds a unique federated identifier, which identifier identifies a single patient (P). Thus, it is possible for the servers to communicate with each other without having to reveal the true identity of patient. By creating one session pseudonym for each pair of providing server (12) holding relevant patient data and a requesting server (10) and by formatting an inbound session identifier related to the requesting server and an outbound session identifier related to the providing server for each session pseudonym the servers may communicate anonymous data with each other. The patient data is transferred from the at least one providing server to the requesting server and all session pseudonyms are replaced, in the requesting server, with the identifier of the requesting server for the patient (P).

Dependent claims

A method for exchanging data between at least two servers with use of a gateway, wherein each server holds a unique federated identifier, which identifier identifies a single patient and may act as a requesting server or providing server comprising the steps of;

sending an original request requesting data of the patient from the requesting server to the gateway;
resolving federated identifiers related to the patient with use of the gateway;
creating, by the gateway, one session pseudonym for each pair of providing server holding relevant patient data and the requesting server;
formatting an inbound identifier array that includes the federated identifier of the patient at the requesting server and an outbound identifier array that includes the federated identifier of the patient at each providing server for each session pseudonym;
relaying each session pseudonym and the identifier arrays to each server, respectively;
transferring the patient data from the at least one providing server to the requesting server, the patient data including the corresponding session pseudonym, and not including an identifier of the patient;
and
replacing all session pseudonyms with the identifier of the requesting server for the patient.

A non-transitory computer readable medium that includes a computer program that, when executed by a processor, causes the processor to:

receive a first request that requests data of a patient who is identified by a first federated identifier at a requesting server,
resolve a second federated identifier related to the patient at a providing server,
create a session pseudonym corresponding to the requesting and providing servers,
create an outbound identifier array that includes the second federated identifier,
form a second request by removing the first federated identifier from the first request,
send the session pseudonym, the outbound identifier array, and the second request to the providing server, and
receive the requested data of the patient from the providing server in a message that includes the session pseudonym and does not include an identifier of the patient.
