Difference between personal and anonymous data.
A distinction is made between personal data and anonymous data.
Personal data is data which allows conclusions to be drawn about individuals. This includes, among other things, the last name, first name, address and telephone number. The Data Protection Act applies to this data.
Anonymous data does not allow any conclusions to be drawn about individuals. It refers to statistics, such as the number of people on a train. The Data Protection Act does not apply to the processing of anonymous data.
