As employers and executives, it is crucial to prioritize the protection of personal information within your organization. One effective method for protecting against inappropriate disclosure is through de-identification, a process that alters personal information to render it non-identifiable to individuals. This approach provides a layer of privacy protection while still enabling data use for research or other purposes. However, it’s essential for organizations to grasp the intricacies of de-identification and its relationship to privacy laws to ensure compliance and protect data subjects.
What is de-identified information?
De-identification involves altering personal information in a way that no longer identifies an individual or can be used to identify them in foreseeable situations. Common direct identifiers, like names, social insurance numbers, and driver’s license numbers, are removed or modified to achieve de-identification.
In Canada, the definition of de-identified information centers on the absence of direct identifiers, ensuring it no longer allows the person concerned to be directly identified. Similarly, in the US, the California Consumer Privacy Act (CCPA) defines de-identified information as data that cannot reasonably identify, relate to, or be linked to a particular consumer.
In the European Union’s General Data Protection Regulation (GDPR), de-identified data is not explicitly defined. However, the GDPR distinguishes between “identified” and “identifiable” natural persons. Personal data used to identify an individual cannot be considered de-identified. Partially de-identified data occurs when the person is not identified but remains identifiable, making it an intermediary level known as pseudonymous data.
Preserving utility while protecting privacy
The main objective of de-identification is to safeguard personal information while still maintaining its utility for research or legitimate purposes. Striking this balance is critical as strong de-identification techniques may reduce data utility significantly. Hence, the level of de-identification applied should align with the data processing purposes.
Anonymous vs. de-identified data
Anonymous data contains no identifiable information and cannot be linked to any individual. De-identified data, on the other hand, lacks identifiable information but can potentially be linked back to an individual alone or in combination with other data. Understanding this difference is crucial for handling the data appropriately and ensuring compliance with privacy laws and regulations.
Applicability of privacy laws
Privacy laws generally protect personal information, which is data that can identify a natural person or data subject. In most jurisdictions, personal information that has been anonymized is no longer subject to privacy laws since it cannot be linked back to an identifiable individual. However, de-identified information may still be subject to privacy laws in some jurisdictions due to the risk of re-identification, which could potentially harm individuals.
In Canada’s proposed Consumer Privacy Protection Act, de-identified information is considered a subset of personal information, subject to some obligations or exemptions. The GDPR treats pseudonymized data as personal data, but it relaxes some requirements for its use. In contrast, the CCPA excludes de-identified information from its scope entirely, provided that certain technical safeguards and processes are in place.
Complying with privacy laws
To effectively manage de-identification practices and meet regulatory expectations, employers must carefully assess their techniques and align them with compliance and business objectives. It is essential to seek the guidance of privacy lawyers to navigate the legal requirements in their jurisdiction and ensure their data practices remain in compliance.
In conclusion, a thorough evaluation of de-identification methods and their strategic relevance is essential for organizations, ensuring alignment with both compliance and business goals. Moreover, a comprehensive comprehension of the legal obligations within their jurisdiction is vital for businesses to abide by pertinent privacy laws. For expert guidance on managing de-identification practices and meeting regulatory standards, seeking counsel from privacy lawyers is strongly advised.
