1. A method, performed by a terminal, comprising:
receiving request information for accessing a first device identifier by a target application;
determining first access permission in association with the target application accessing the first device identifier; and
returning, in response to determining that the first access permission is allowing access to a dummy value of the first device identifier, the dummy value of the first device identifier to the target application,
wherein the dummy value of the first device identifier is a preset value different from a real value of the first device identifier, or
wherein the method further comprises:
obtaining the dummy value of the first device identifier by performing anonymization processing on the real value of the first device identifier using at least one of a randomized algorithm or a generalization algorithm.
