Privacy Protection

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 cost-benefit motivations instead of diligent and ethical practices for collecting, storing, sharing and using personally identifiable information (PII).

Attain Insight Intrinsic is a unique technology that enables organizations to anonymize user identity information, including everything from driver’s licenses to facial recognition biometric data.  Anonymized 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 protected.

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 eliminates regulatory and custodial burdens while preserving the ability to securely search and match biometric identifiers. This anonymized data can be used for a number of important functions:


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

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
  • Find individuals in common with another organization without sharing any personally identifying data
  • Create trust frameworks – selective attributes can become part of the verifiable credential or digital wallet applications
  • Review PII concerns related to Age and Liveliness

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. SPAn is compliant with privacy policies in most countries and jurisdictions, including Canada, USA, UK, Australia, member countries of the European Union, and New Zealand.
