Federal Privacy Commissioner Issues Biometrics Guidance for Public and Private Sectors
In a significant move to address growing concerns over the use of biometric technologies, the Office of the Privacy Commissioner of Canada (OPC) has released comprehensive guidance for both public and private sector organizations. This detailed framework outlines their privacy obligations when collecting, using, and disclosing biometric data, such as facial recognition, fingerprint scanning, and voiceprint technologies.
The guidance follows an extensive public consultation process conducted between November 2023 and February 2024. During this period, the OPC gathered input from a diverse range of stakeholders, including academia, civil society, businesses, legal associations, and individuals. The result is a clear roadmap for organizations to navigate the complex landscape of biometric data privacy.
Understanding Biometrics
Biometrics refers to the process of quantifying human characteristics into measurable data. These characteristics can be broadly categorized into two types:
- Physiological biometrics: These are stable, unique features such as fingerprints, iris patterns, facial geometry, and DNA.
- Behavioural biometrics: These are patterns derived from movements or actions, such as keystroke dynamics or gait.
Importantly, photographs, videos, or observed behaviours only qualify as biometric information if they are processed into quantifiable data. This distinction underscores the evolving nature of biometric technologies and their potential privacy implications.
The Sensitivity of Biometric Data
Biometric information is considered highly sensitive because it is deeply tied to an individual’s identity. Unlike passwords or PINs, biometric data is unique, immutable, and often impossible to change. This makes it a prime target for malicious actors.
If biometric data is breached, the consequences can be severe. It can enable mass surveillance, expose individuals to fraud and identity theft, and even reveal sensitive personal information about health, race, disability, gender, or biological family relationships. Additionally, concerns about the accuracy of biometric technologies persist, particularly when they are used for automated decision-making. Errors in these systems can lead to unfair outcomes, exacerbating existing biases and discrimination.
These risks highlight the urgent need for robust safeguards and clear guidelines to ensure responsible use of biometric technologies.
Key Privacy Principles from the Guidance
The OPC’s guidance establishes several key principles that organizations must adhere to when handling biometric data. These principles are designed to ensure that the collection, use, and disclosure of biometric information are conducted responsibly and with respect for individuals’ privacy rights.
Appropriate Purpose
Organizations must demonstrate a legitimate need for collecting biometric data, tied to a valid business or public interest. The guidance emphasizes four key criteria for evaluating the appropriateness of biometric data collection:
- Legitimacy: The collection must serve a valid purpose that aligns with the organization’s mandate or business needs.
- Effectiveness: The technology must be proven to be reliable, with low error rates and high accuracy.
- Minimal Intrusiveness: Organizations should opt for less invasive alternatives unless the use of biometrics is strictly necessary.
- Proportionality: The privacy impact of biometric data collection must be proportionate to the anticipated benefits.
No-Go Zones
The OPC has identified certain uses of biometric technologies as generally inappropriate. These include:
- Unlawful collections of biometric data.
- Profiling that leads to discrimination or unfair treatment of individuals.
- Surveillance that causes significant harm to individuals or groups.
- Surveillance via personal devices without proper justification and safeguards.
Consent and Transparency
Informed consent is a cornerstone of Canadian privacy law, and organizations must obtain meaningful consent from individuals before collecting, using, or disclosing their biometric data. This requires:
- Clear and understandable disclosure of how biometric data will be used.
- Robust consent mechanisms that are ongoing and allow individuals to withdraw their consent easily.
- Transparency about the purposes and risks associated with biometric data collection.
Security and Training
Given the sensitivity of biometric data, organizations must implement special security measures to protect it. This includes:
- Adopting strong security controls to prevent unauthorized access or breaches.
- Training staff who handle biometric data on privacy best practices and security protocols.
- Supervising employees to ensure compliance with privacy obligations.
Accuracy and Testing
Organizations are required to regularly test the reliability and accuracy of biometric systems. This is particularly important because errors in biometric technologies can lead to serious privacy and ethical issues, such as unfair or discriminatory outcomes. Regular testing helps ensure that these systems operate fairly and transparently.
Application to Public and Private Sectors
The guidance applies differently to federal institutions and private sector businesses, reflecting the distinct legal frameworks that govern each sector.
Federal Institutions
For federal institutions, the guidance is grounded in the Privacy Act and emphasizes compliance with all relevant laws, regulations, and policies. The OPC, in collaboration with provincial and territorial privacy authorities, has issued additional guidance for specific contexts, such as the use of facial recognition by law enforcement. These resources help federal agencies understand their obligations and align their practices with evolving privacy standards.
Businesses
Under the Personal Information Protection and Electronic Documents Act (PIPEDA), businesses are required to take a privacy-first approach to biometric data. While some provinces have introduced explicit statutory language on biometric data, PIPEDA’s principles-based approach means that compliance requirements may evolve over time. Businesses must be prepared to meet a higher bar for privacy protection and adapt to new developments in privacy law.
International Context
Canada’s biometrics guidance aligns with global trends in privacy regulation. For example, New Zealand has recently introduced a biometric privacy code that emphasizes transparency, proportionality, and technical safeguards. Like Canada’s framework, New Zealand’s code prohibits certain high-risk uses of biometric technologies, such as predicting emotions or inferring protected characteristics like ethnicity or health status.
These international developments highlight the growing recognition of the need for robust privacy protections in the digital age. By aligning with global standards, Canada’s guidance ensures that Canadian organizations can operate effectively in international markets while maintaining high standards of privacy protection.
Practical Steps for Organizations
To comply with the OPC’s guidance, organizations should take the following practical steps:
- Evaluate Necessity: Assess whether biometric technologies are truly necessary for the intended purpose.
- Prefer Less Intrusive Alternatives: Choose less invasive methods unless biometrics are strictly required.
- Obtain Informed Consent: Ensure individuals understand how their biometric data will be used and provide meaningful consent.
- Restrict Retention and Use: Limit the retention and use of biometric data to only what is strictly necessary.
- Implement Advanced Security Measures: Protect biometric data with robust security controls to prevent breaches.
- Regularly Review and Test Systems: Periodically assess biometric systems for accuracy, fairness, and compliance with privacy obligations.
By following these steps, organizations can adopt biometric technologies responsibly, balancing innovation with the protection of individuals’ privacy rights. The OPC’s guidance reflects the increasing expectations for transparency, accountability, and ethical use of biometric technologies as they become more prevalent in society.
Conclusion
The Office of the Privacy Commissioner’s guidance on biometric data underscores the importance of responsible innovation in an increasingly digital world. By emphasizing key principles such as appropriate purpose, minimal intrusiveness, and informed consent, the OPC provides a clear framework for organizations to navigate the complexities of biometric technologies. As these technologies become more prevalent, organizations must prioritize transparency, security, and ethical considerations to maintain public trust and comply with evolving privacy standards. By following the practical steps outlined in the guidance, organizations can harness the benefits of biometrics while safeguarding individuals’ privacy rights.
