A computer-implemented method of implementing information security. The method can include receiving a user input comprising a first user identifier and at least a second user identifier, determining whether the first user identifier corresponds to at least one of a plurality of existing user profiles, and determining whether the second user identifier corresponds to at least one of the plurality of existing user profiles. When it is determined that the first user identifier does not correspond to at least one of the plurality of existing user profiles, but that the second user identifier does correspond to at least one of the plurality of existing user profiles, the method can include selecting the user profile to which the second user identifier corresponds, automatically generating a unique user identifier, and associating the unique user identifier with the selected user profile.
