An optical element driving device is provided with at least one optical element, a moving member, a fixed member, a first actuator, a first detection element, a second actuator, and a second detection element. The vibration element includes at least one superimposed layer structure comprising a pair of electrical energy to mechanical energy conversion elements and an elastic member sandwiched between the pair of electrical energy to mechanical energy conversion elements. Moreover, the present invention uses the arrangement of antenna diversity to install two antennas on a base board at the same time, thereby obtaining better antenna performance. The message to be encrypted can be obtained via performing a hash function on the source data on the digital object to obtain a message digest.
