Protect PII Data with Search-Preserving Anonymization

With the advent of privacy legislation in nearly every jurisdiction, the legal and reputational risks of unethical or insecure data practices are unfortunately often being driven by motivations to contain cost instead of diligent and responsible practices for collecting, storing, or sharing personally identifiable information (PII).

Attain Insight Intrinsic is a unique technology that enables organizations to protect user identity information, including everything from driver’s licenses to facial recognition biometric data.  Protected data is low risk from a security perspective because it cannot be ‘decoded’ or linked back to any specific individual, meaning that an individual’s privacy has been safeguarded, while still satisfying the business need.

Intrinsic protects privacy with Search-Preserving Anonymization (SPAn) – a Biometric Privacy Enhancing Technology (B-PET) that transforms data in a one-way process. By removing all Personally Identifiable Information (PII), SPAn simplifies regulatory and custodial obligations while preserving the ability to securely search and match biometric identifiers. This transformed data can be used for a number of important functions:


Attain Insight Intrinsic provides anonymity for both biometric and non-biometric data.

Search-Preserving Anonymization (SPAn)

Traditional privacy controls often focus on restricting access to biometric data. Search-Preserving Anonymization (SPAn) takes a different approach by transforming biometric templates into a format that can still be searched, matched, and verified without exposing personally identifiable information.

SPAn is designed to retain only the proximity information required for biometric comparison while preventing re-identification and the derivation of secondary characteristics such as age, gender, ethnicity, or eye colour. The result is a privacy-first approach that supports authentication, verification, classification, collaboration, and other biometric use cases while significantly reducing privacy risk.

By minimizing the biometric information that is retained SPAn helps organizations simplify compliance efforts and reduce exposure to data breaches.

Privacy Protection Features

Intrinsic’s Search-Preserving Anonymization enables organizations to:

  • Secure and anonymize Personally Identifiable Information (PII) data, including facial recognition, biometric and non-biometric data
  • Match anonymized PII data with other organizations
  • Support inter-agency collaboration between multiple organizations with independent databases without exposing PII (E.g. Which agencies know this person?)
  • Work together with other organizations, leveraging one centralized biometric database, or, separate databases managed by each organization, or, fully decentralized (no database) solutions
  • Find individuals in common with another organization without sharing any personally identifying data
  • Support trust frameworks, verifiable credentials and digital wallet applications
  • Address PII concerns related to Age and Liveliness checks

This capability, offered only by Attain Insight, can assist with intelligence collection, public safety, anti-fraud practices, improved government programming and citizen privacy protection.

Note: Intrinsic’s new anonymization component, announced in 2024, is the only solution in a new and distinct class of Biometric Privacy Enhancing Technologies (B-PETs) called Search-Preserving Anonymization (SPAn) that significantly reduces regulatory and custodial responsibilities by removing PII while still enabling searching and matching against biometric datasets. Many global privacy regulations implicitly require SPAn by necessitating optimal data minimization. These include the European Union GDPR, California CCPA / CPRA, Texas TDPSA, Utah UCPA, Brazil LGPD, Canada PIPEDA, United Kingdom UK-GDPR, Australia APP and New Zealand IPP.
