Methods and systems for rules-based data access are described. In some embodiments, a request for access to customer data by a requesting entity is received; the data is categorized; the person's preferences with respect to allowing access to data are compiled; a requesting entity is determined; and the providing entity that collected each requested data item is determined. Data shareability rules are evaluated based on the policies that regulate the access of the customer data and the requesting entity, and the customer data is provided to the requesting entity according to the evaluation.
