When it comes to private investigations, processing personal data without the individual’s knowledge, commonly known as invisible processing, is a frequent practice. This article explores what invisible processing entails and the responsibilities private investigators must uphold under data protection laws.
What is Invisible Processing?
Invisible processing involves collecting and using personal data without the individual being aware of it. Examples include obtaining information through third-party sources or tracking data via online activities. While invisible processing is often essential for investigative work, it carries significant risks. If individuals are unaware their data is being processed, they cannot exercise their data protection rights or control how their data is used.
Professional investigators must carefully evaluate their legal basis for such processing and ensure they can justify its necessity. Even when invisible processing impacts an individual, it may be permissible if the investigator’s legitimate interests outweigh those of the individual, provided it is handled with care and consideration.
Exceptions to Providing Privacy Information
Under UK GDPR, investigators are usually required to inform individuals how their data is being used. However, exceptions exist in cases where:
- Providing privacy information would be impossible.
- It would involve disproportionate effort.
- It would undermine the purpose of the investigation.
Even when these exceptions apply, investigators must ensure transparency by publishing general privacy notices and conducting a Data Protection Impact Assessment (DPIA).
The Role of Data Protection Impact Assessments
DPIAs are vital tools for balancing individual rights and the investigator’s objectives. When privacy information cannot be provided directly, a DPIA helps assess risks, identify mitigations, and demonstrate compliance with data protection principles.
Examples of Invisible Processing in Investigative Work
- When Providing Privacy Information is Impossible
An investigator tracing a person without current contact details must attempt to provide privacy information within a reasonable period (usually one month). If it takes longer to locate the individual, the investigator can rely on the exception until contact is made. - When Providing Privacy Information is Disproportionate
Searching publicly available records for an investigation may not always yield relevant results. In such cases, contacting individuals based on irrelevant data may be deemed disproportionate if it causes unnecessary impact or has no effect on those individuals. - When Privacy Information Impairs the Objective
Covert monitoring for suspected misconduct may fail if the individual knows they are being monitored. Informing them in advance would compromise the investigation. In such cases, a DPIA justifies the use of this exception.
Exemptions in Legal or Criminal Contexts
Certain exemptions under data protection law apply, such as:
- Cases involving crime prevention or detection.
- Situations where informing individuals would hinder ongoing legal proceedings or obstruct legitimate investigative goals.
These exemptions ensure that investigators can pursue lawful activities without jeopardising their objectives, while still upholding compliance with data protection principles.
Invisible processing is an essential aspect of professional investigations, but it comes with significant responsibilities. Investigators must ensure compliance with data protection laws, maintain transparency wherever possible, and balance their objectives with individuals’ rights. By using tools like DPIAs and adhering to GDPR requirements, investigators can minimise risks and maintain ethical practices in their work.
