l-Diversity

L-diversity is a method used in data privacy to protect sensitive information. It ensures that within any group of records that share the same characteristics (like age or zip code), there is a variety of sensitive attributes (such as health status or income). The idea is that if a dataset has multiple distinct values for these attributes, an individual's information is less likely to be inferred or re-identified, thus providing stronger privacy protection. Essentially, L-diversity promotes a balance of information, making it harder for someone to learn about someone's private details from the data.
