PETs are increasingly important in Europe, where protecting user privacy and data security is a top priority. Although, we’re not talking about dogs, cats, or hamsters. Privacy Enhancing Technologies (PETs) are tools and techniques that limit access to personal data and control its use. Some examples of PETs include encryption, anonymisation, and access controls.

PETs help prevent data breaches, identity theft, and other privacy violations, building trust between users and organisations. Regulatory frameworks related to PETs are evolving. Therefore, organisations must comply with these regulations to avoid penalties and build trust with their users. In today’s digital age, personal data collection, use, and sharing are ubiquitous, making safeguarding user privacy and security imperative.

Common themes in PET regulations

While some European countries have different regulations and requirements related to PETs, some common themes emerge from the GDPR – which applies throughout the EU. These themes include obtaining informed consent for data collection and use, being transparent and providing adequate information to users, and implementing technical solutions, staff training, and policies and procedures related to data privacy and security.

Germany: obtaining informed consent for third-party tracking

In Germany, website operators must obtain user consent before using third-party tools to track user behaviour for advertising purposes. Consent must be informed, meaning users must know what they agree to, and transparency is critical.

France: valid user consent for targeted advertising

The French Data Protection Authority, CNIL, has provided guidance about obtaining proper consent for targeted advertising in France. It is a legal obligation and an ethical responsibility. Being transparent and providing adequate information to users is crucial for building trust and maintaining a healthy online environment.

The Netherlands: PETs in the healthcare sector

In the Netherlands, PETs are used in the healthcare sector to protect patient data. The Dutch Data Protection Authority, AP, has provided guidance on implementing measures to ensure patient data’s confidentiality, integrity, and availability.

Sweden: Privacy risks of facial recognition in education

In Sweden, privacy concerns related to facial recognition technology in the educational sector have led to cautionary guidance regarding the improper use of PETs. Therefore, organisations should limit facial recognition technology to specific areas and purposes, provide clear information to individuals about how their data is being collected and used, and implement strict access controls to limit who has access to the data. The Swedish Data Protection Authority, IMY, has provided guidance about implementing these measures and has the power to enforce penalties for non-compliance.

PETs are essential in safeguarding user privacy and building trust

PETs are critical in protecting user privacy and data security in Europe, because they are necessary for preventing privacy violations and building trust between users and organisations. So, by adhering to regulations and implementing PETs, organisations can avoid penalties and build trust with their users. Some might say that PETs are our best friends, just like our furry companions.
