Can a data collection process claim to be anonymous?
If data is in any way identifiable, or can be connected to the user (directly or indirectly), the data collection process cannot make the claim of being anonymous. Confidential data is usually coded so that the subject is assigned a unique identifier. The subject’s identity is kept separate from the code and data.
Can a person retrace a data anonymization process?
However, even when you clear data of identifiers, attackers can use de-anonymization methods to retrace the data anonymization process.

Is it possible to use anonymous tracking data?

What are the pros and cons of anonymization?
The GDPR stipulates that websites must obtain consent from users to collect personal information such as IP addresses, device ID, and cookies. Collecting anonymous data and deleting identifiers from the database limit your ability to derive value and insight from your data.
What’s the difference between anonymous and confidential data?
Confidential vs anonymous data collection The difference between confidential and anonymous data collection is that confidential data contains a link that can be used later to retrieve user’s identity, while anonymous data is recorded so that the information can never be linked to the subject who supplied it.
Can a study be both anonymous and confidential?

What is anonymous data required for the use of GDPR?
