1.5 Privacy and sensitive data concepts in relation to security
Privacy enhancing technologies
Privacy Enhancing Technologies (PETs) are techniques and tools used to protect the privacy of individuals by minimizing or transforming sensitive data. PETs are an important aspect of data privacy and security, and help organizations meet regulatory requirements and reduce the risk of privacy breaches.
1. Data Minimization: This involves collecting and storing only the minimum amount of data necessary for a specific purpose. This reduces the amount of sensitive data that is at risk of being exposed in the event of a breach.
2. Data Masking: This involves obscuring or replacing sensitive data with false information that cannot be used to identify individuals. Data masking helps prevent unauthorized access to sensitive data.
3. Tokenization: This involves replacing sensitive data with a unique, non-sensitive representation known as a "token". Tokens cannot be used to identify individuals and are used instead of sensitive data in transactions and processing.
4. Anonymization: This involves removing personally identifiable information (PII) from a data set, making it impossible to identify individuals. Anonymized data can be used for research and analysis, but cannot be linked to specific individuals.
5. Pseudo-anonymization: This involves obscuring or masking PII in a data set, making it difficult to identify individuals, but not impossible. Pseudo-anonymization is sometimes used for testing and development purposes.
