A server receives target data sent by a mobile terminal, the target data carrying a parameter set, the parameter set including at least a target posture parameter of the mobile terminal. When the amount of change in posture variation is smaller than the preset variation threshold, such fact indicates that the posture when the mobile terminal sends the target data hardly changes compared with the postures that the mobile terminal historically sends the target data to the server. As the posture of the mobile terminal is frequently changed during the process of normal use of the mobile terminal, the target data sent by the mobile terminal without posture change is regarded as false data. Thus, the present techniques ensure the fairness and efficiency of data processing.
