Why Privacy by Design?
The idea behind Privacy by Design is that data protection can best be guaranteed at the point when it is built into the technology. However, there is also a lot of uncertainty about how Privacy by Design can be implemented. This is partly due to the fact that the GDPR, which includes the principle of Privacy by Design, does not specify exactly what measures must be taken to implement Privacy by Design, and partly due to the fact that this principle is incompletely implemented by member states that must comply with the rules laid down in the GDPR.
An important feature of Privacy by Design is that it takes a proactive and preventative approach to reducing data protection risks. Because data protection is taken into account from the outset, it offers very strong safeguards that are of great importance in the protection of privacy. This is also called end-to-end security, "from cradle to grave".
Several points should be taken into account when developing technologies
User authentication and technical implementation of the user's right to object should be taken into account and precautions should be considered. In addition, the type, extent, circumstances and purpose of the processing should be weighed against the possibilities of the occurrence of data processing risks and the seriousness of those risks.
Compliance with legal requirements
In practice one often sees that several of the above mentioned points, or even all of them, are implemented in the technology through Privacy by Design. In this way, the technology can meet the requirements of the law from the outset. Certification is often used to prove that the developers have met the requirements of Privacy by Design.
