HOSPITAL MATCHING OF DE-IDENTIFIED HEALTHCARE DATABASES WITHOUT OBVIOUS QUASI-IDENTIFIERS

摘要

Electronic processors (14) are programmed to perform the N anonymous health cares database (10) of integrated (16). A pair of of database (i, j) N anonymous health care databases, one group of feature are identified a pair of of database (i, j) of each two databases i and j included in (44). Conversion table, a pair of of database can be endured based on similarity measure by generating (46 48) matching patient, pass through this feature collection. It is each uniquely database N anonymous health cares database to generate N 1 that identification and generation operation, which repeat (50))/2 conversion tables (20). Patient's N anonymous health care databases contained in the patient of N anonymous health cares database and retrieval patient that electronic processors are further programmed to perform patient data's retrieving (18) reception patient use N number of (N-1)/2 conversion table.
