Title:
MULTI-SOURCE LONGITUDINAL PATIENT-LEVEL DATA ENCRYPTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2005/109294
Kind Code:
A3
Abstract:
Systems and processes for assembling de-itendified patient healthcare data records
in a longitudinal database are provided. The systems and processes may be implemented
over multiple data suppliers and common database facilities while ensuring
patient privacy. At the data supplier locations, patient-identifying attributes
in the dtaa records are placed in standard format and then doubly encrypted using
a pair of encryption keys before transmission to a common database facility. The
pair of encryption keys includes a key specific to the data supplier and a key specific
to the common database facility. At the common database facility, the encryption
specific to the data supplier is removed, so that multi-sourced data records
have only the common database encryption. Without direct access to patient identifying-information,
the encrypted data records assigned dummy labels or tags by which the data records
can be longitudinally linked in the database. The tags are assigned based on statistical
matching of the values of a select set of encrypted data attributes with a reference
database of tags and associated encrypted data attribute values.
