Businesses, governments, and other entities verify the identity of customers in order to assess their trustworthiness and to avoid potential losses. Identity is often determined by confirming the ownership of an identifier, e.g., phone number. However, successfully determining an individual’s ownership of an identifier is insufficient to assess the reputation or trustworthiness of the individual. This disclosure describes the use of social graphs to robustly determine the identity and trustworthiness of an individual via their associations with other individuals or entities. Data from individuals associated with a potential customer are utilized, with permission from respective users, for the purpose of identity verification and/or determination of trustworthiness.
