Outsmart Risk. Find & Consistently Anonymize PII in Structured, Semi-Structured, and Unstructured Sources.

Classify, Locate, De-Identify, and Prove

Unmasked data can damage your company's reputation and cost it millions in fines. Award-winning data masking tools from IRI have been repeatedly proven in a wide range of data breach nullification, privacy law compliance, and DevOps (test data) environments. Use fit-for-purpose IRI data 'shield' products (or all of them in the IRI Voracity data management platform) to find and mask sensitive data deterministically on-premise or in your cloud, and to prove that you protected it.

Comply with Data Privacy Laws

Data privacy laws require that key identifiers be encrypted, pseudonymized, redacted, or anonymized, or that people cannot be traced by their quasi-identifiers. IRI data masking tools can find and fix PII in any format to meet the data erasure, portability and rectification requirements of the GDPR et al, and score re-ID risk for HIPAA, etc. Inquire about your mandates.

Apply Multiple Masking Methods

Use the IRI Workbench IDE for IRI FieldShield or DarkShield built on Eclipse™ to discover, classify, and mask data quickly and easily. Blur, encrypt, hash, pseudonymize, randomize, redact, scramble, tokenize, etc. Match the data masking function to your search-matched data classes (or column names), and apply it consistently to preserve realism and referential integrity enterprise-wide.

Use Role Based Access Controls

Decide and enforce who can access or use specific data sources and targets; masking rules and job scripts; data classifications and data layout definitions; decryption keys and log files; and, even the masking programs themselves. Establish different roles for different data sources, and different access rights based on those roles. 

Define, Assign, and Follow RBAC Rules →

Leverage Multiple Audit Logs

All IRI data obfuscation tools produces machine-readable audit logs that you can secure, query, and display, or export to SIEM tools, to: reliably document everything that's been changed, verify compliance with data privacy laws without tampering concerns, trigger alerts, and take action. That is how auditing is supposed to work.

Types of Sensitive Data

  • Personally Identifiable Information (PII)
  • Protected Health Information (PHI)
  • Primary Account Numbers (PANs)
  • Other Sensitive Information

Personally Identifiable Information (PII)

While there is no set list of PII across all privacy laws, there are common elements used across these laws. In short, PII is information, when used alone or with other data, that identifies an individual. Government regulations like the CCPA, SSAE 16, SOC 2, and GDPR require that all PII be protected.

Protected Health Information (PHI)

In medical records, PHI identifies a health care recipient. US HIPAA regulations require that 18 key identifiers be effectively de-identified or anonymized.

Primary Account Numbers (PANs)

PANs are identifying numbers used in credit card transactions. The Payment Card Industry Data Security Standard (PCI DSS) requires card issuers, merchants, and testers to encrypt, tokenize, and otherwise protect this information.

Other Sensitive Information

Information like codes and formulas that constitute trade or military secrets need to be protected. You cannot afford to have this critical data lost in a data breach.

Privacy Laws

  • GDPR
  • CCPA


The Health Insurance Portability and Accountability Act of 1996 (HIPAA) implements industry-wide standards for health care information. Health care providers, organizations, and their associates are required to develop and follow procedures for PHI when it is transferred, received, handled, or shared. It applies to all forms of PHI, including written, electronic, and oral.


Under the General Data Protection Regulation (GDPR), all personal data of a citizen from the European Union must be secured. Companies are required to protect any data that can directly or indirectly identify an individual ("data subject"). These identifiers include, but are not limited to:

  • Social Security Number
  • Credit Card Number
  • Bank Account Number
  • First Name
  • Last Name
  • Address
  • Zip Code
  • Email Address
  • Medical Information
  • Genomic Information
  • IP Address
  • GeolocationData
  • Income and Tax Data
  • Race, Ethnicity, and Religious Affiliation
  • Sexual Orientation
  • Trade Union Membership
  • Birth Date
  • Password
  • Military ID
  • Passport Number
  • Driver's License Number
  • Vehicle License Number
  • Phone and Fax Numbers

The law also provides citizens with the Right to be Forgotten, or the ability to request that all information about them be removed from a company's possession. IRI data obfuscation products find that PII and PI you need in text, image, or facial form, and tell you where it is, and (immediately or later) automatically delete, deliver, and fix it so you can comply with GDPR right to erasure, portability and rectification provisions.


The Family Educational Rights and Privacy Act (FERPA) is a federal law that protects the privacy of student records and information. FERPA gives rights and protections to parents and eligible students. Once a student reaches 18 years of age or enrolls in a post-secondary institution, he or she becomes an "eligible student," meaning all rights formerly controlled by the parents transfer to the student.

Under FERPA, a school may not generally disclose PII from an eligible student's records to third parties unless the student has provided written consent. Data protected includes PII and no less than the following additional information:

  • Student Name
  • Student ID Number
  • Family Member Names
  • Place of Birth
  • Mother's Maiden Name
  • Student Educational Records
  • Immunization Records
  • Health Records
  • Individuals with Disabilities (IDEA) Records
  • Attendance Records


The Federal Information Security Management Act of 2002 (FISMA) is a federal law that recognizes the importance of data protection and information security to economic and national security interests. Every federal agency must develop, document, and implement an agency-wide course of action to secure the system and assets that support the agency, including those managed by another agency, contractor, or other sources.

Information that must be protected under FISMA includes PII and other sensitive information from these categories:

  • Medical
  • Financial
  • Contractor Sensitive
  • Security Management
  • Other information specified by executive order, specific law, directive, policy, or regulation


The Federal Financial Institutions Examination Council (FFIEC) is a government inter-agency body that sets uniform principles, standards, and report forms to promote uniformity in the supervisions of financial institutions. Additionally, the Council oversees real estate appraisal.

Banks, credit unions, and other financial institutions are subject to the rules enacted by the Council. In addition to PII and Non-Public Personal Information (NPI), these institutions need to protect:

  • Income
  • Credit Score
  • Collection History
  • Family Member PII and NPI


The California Consumer Privacy Act of 2018 (CCPA) protects the data of Californians from being collected and mishandled. The law grants the citizens of California the rights to know all the information a business collects on them, to forbid companies from selling their data, to delete their data, and more.
