Anonymize is the process of protecting people's privacy by removing or changing their personal information from data sets. Simply put, anonymizing makes data anonymous so it cannot be connected back to any individual.

Why Anonymize Matters

In today’s digital world, a lot of sensitive information is collected and used in areas like healthcare, finance, and customer service. Anonymizing data is important to keep personal details private, protecting people from privacy breaches and the misuse of their information.

Key Techniques for Anonymizing Data

1. Data Masking
   • Description: Replaces sensitive information with fake or generic values.
   • Example: Changing a specific birthdate to just an age or age range.
2. Generalization
   • Description: Makes specific details more general.
   • Example: Changing an exact address to just the city or region.
3. Pseudonymization
   • Description: Replaces private identifiers with fake names or codes.
   • Example: Using a unique code instead of a person’s name.
4. Noise Addition
   • Description: Adds random data to hide the original data.
   • Example: Slightly changing financial numbers to protect exact amounts.
