<p>PROBLEM TO BE SOLVED: To attain a system that enables a personal identification non-visible type linkage for easily obtaining corresponding linkage information without taking out all linkage information associating with personal identification information and clinical research data and without decoding a plaintext.SOLUTION: A management method for clinical research data and personal identification information is configured to: generate an open key for coding data and a secret key corresponding to the open key; by using medical information transmitted by a user device 10-i and the open key as an input, generate and store linkage information, a retrieval tag, personal identification information and clinical research data; by using a user query received from the user device 10-i and the secret key as an input, generate a retrieval query. A linkage information storage device 50 retrieves by using a set of the stored retrieval tag and the retrieval query as the input, transmits corresponding linkage information to a data browse device 40, and the data browse device 40 obtains corresponding personal identification information on the basis of the received linkage information and clinical research data thereon.</p> |
