A method for associating a web event with a member of a group of users is implemented at a first computing device. The method includes: receiving a data access request from a second computing device; determining whether the user has previously provided personal information and authorization to the first computing device through the second computing device; if the user's personal information and authorization are found: generating a record for the data access request; if the user's personal information is found but the user's authorization is not found: generating a record for the data access request; and if neither of the user's personal information and authorization is found: identifying one or more user identifiers that are associated with the second computing device; and returning personal information associated with the one or more user identifiers to the second computing device.
