Active data collection refers to data that is collected knowingly and transparently from the user, such as through a web form, check box, or survey.

Data Anonymization is a process that alters personally identifiable data (PII) in such a manner that it can no longer be used to identify an individual. This can be done by removing certain identifying values from data sets, or by generalizing identifying values.

In data security or privacy terms, this is the breach of a legal duty to protect personal information.
