ℓ-diversity is an advanced anonymization algorithm. In order to anonymize data more reliably while also loosing less potentially valuable information, implement ℓ-diversity. Other anonymization algorithms could also be taken into consideration.
[ ] write a PHP library that can anonymize arrays of objects with l-diversity (that's the form that returned database records have)
[ ] use the PHP library to anonymize the queried records before storing
[ ] for dataset
[ ] for related_data
[ ] check that relations between tables are kept, while also avoiding them to give away identity
