How it works — simple matching example
Record Linking
The BMPI performs this matching process for all demographic fields to determine which records belong to the same individual. It minimizes false positives by only linking records when there is high confidence of a match.

Hashing
Before storing a record, the BMPI performs an irreversible hash operation on the demographic data. The BMPI only stores and performs match operations with the hashed values, not the original values. This is the “blinded” nature of the BMPI.
Secure. Private
The BMPI API platform complies with the security and privacy controls defined by NIST 800-53 Rev. 4 at the FISMA Moderate baseline. We regularly undergo external formal assessments by a FedRAMP-accredited Third Party Assessment Organization (3PAO). Our platform has been granted an Authorization to Operate (ATO) by the National Institutes of Health (NIH) and is FDA Part 11 Compliant.
The CareEvolution BMPI uses only FIPS compliant hash functions (HMAC/SHA256) with a unique client-specific key to ensure privacy and guard against brute force or dictionary attacks.
