True or False: Anonymising personal data is always possible.

Anonymising personal data is not always possible due to various factors, including the nature of the data itself, the context in which it is used, and the potential for re-identification. Anonymisation requires transforming personal data in a way that prevents the identification of individuals, which can be complex.

Factors that can hinder effective anonymisation include:

1. Data Complexity: Some data sets may contain unique identifiers or combinations of attributes that can effectively identify individuals even after attempts at anonymization.

2. Re-identification Risks: With advances in data analytics and the availability of other data sources, there are situations where anonymised data can be re-identified, especially if it is linked with other publicly available data.

3. Specific Use Cases: In some scenarios, particularly when data must retain certain characteristics for analytical purposes, it may not be feasible to fully anonymise without losing essential value.

Considering these aspects, it becomes clear that, while anonymisation is a powerful tool for protecting personal data, it isn't guaranteed to be achievable in all situations, making the assertion that it is always possible inaccurate.
