摘要
Software applications are provided for integrating individual multi-sourced patient healthcare transaction data records in a longitudinal database. The data records are processed in a manner which preserves patient privacy by encrypting patient-identifying attributes in the data records and thereby rendering sensitive personal information inaccessible. The applications, which may be organized as modules using common frame work components, are designed to process the multi-sourced data records at data supplier sites and at a common database assembly facility. The applications provide the data supplier sites and the database facility with methods for acquiring attributes, standardizing formats, encryption key generation, and encrypting and decrypting attributes in the data records. The encryption application provides methods for double encryption of the data records at data supplier sites using a key specific to a data supplier and a key specific to the database facility.
