PIPEDA Report of Findings #2018-003: Facebook agrees to stop using non-users’ personal information in users’ address books
The Office of the Privacy Commissioner of Canada (OPC) investigated a complaint against Facebook Inc. following a 2013 privacy breach where contact information, including that of non-users, was inadvertently disclosed via the 'Download Your Information' (DYI) tool. The investigation focused on Facebook's safeguards, consent practices for its 'matching across address books' process for both users and non-users, and the ability for individuals to access and correct their personal information. The OPC found Facebook's safeguards inadequate prior to the breach, but deemed the issue resolved after Facebook implemented a new Privacy Framework. While Facebook's use of user contact information for matching was found not to contravene consent principles, the OPC determined Facebook was not sufficiently open about these practices, an issue conditionally resolved by Facebook's commitment to revise its notices. The OPC also found Facebook used non-users' personal information for matching without meaningful consent, an issue resolved by Facebook's agreement to stop maintaining such data. Finally, Facebook was found not to be providing adequate access to and correction of matched data, which was resolved through an interim solution.
