HIPAA Security Rules

De-Identifying Protected Health Information

Through field-level encryption and other anonymization functions in the IRI FieldShield and CellShield data masking products, or the IRI Voracity platform, you can de-identify protected health information (PHI) subject to HIPAA regulations, which include 45 CFR 164.312 and 170.210 (requiring encryption, hashing, etc.).


IRI software supports the HIPAA Safe Harbour standard directly by redacting or otherwise obfuscating key identifiers. And, through integrated re-ID risk scoring technology and data generalization technologies, you can determine re-identifiability risk and blur quasi-identifiers to comply with the Expert Determination Method standard, too.

IRI can also deliver professional services and refer you to expert statisticians, HIPAA consultancies, and regulatory attorneys with whom we partner. You can leverage these tools and teams as needed to obtain compliance certification and cybersecurity insurance, and to defend against fines or breach-related claims. See our free course details below.


De-identification refers to processes that disassociate personally identifiable information (PII) within protected health information (PHI) repositories and other "data at risk."

PHI de-identification is a specific requirement in the healthcare industry, where for example, it is used in both "safe harbor" and "expert determination method" practices in medical research (to remove patient identities from study models). De-identification is also a blanket term referring to the anonymization or masking of PII in many other industries.

The most recent Security Rule in HIPAA regulations (45 CFR Parts 160 and 164) spell out the compliance requirements for those entities managing PHI. HIPAA rules apply to 18 specific identifiers:




Phone #

Fax #

Email Address

Social Security #

Medical Record #

Health Insurance Beneficiary #

Account #

Certificate #

Vehicle ID #

Device ID #

Personal URL

IP Address

Biometric ID

Facial Image

Other Unique ID Code


Each of the data masking software products in the IRI Data Protector suite helps you find and classify, and then  protect PII, PAN, PHI, etc. in multiple data sources for Safe Harbor rule compliance. They also work hand-in-hand with free, advanced re-ID risk scoring technology for compliance with the Expert Determination Method rule.
