The first subsequent operation is as follows: as long as the authority of one of the electronic device 9A, the electronic device 9B and the electronic device 9C is determined to be permitted, the processor 15 will define at least a part of the information stored in the storage 13 according to the authority. The protection status of 20 is public. Otherwise, that is, if the rights of the electronic device 9A, the electronic device 9B, and the electronic device 9C are all judged as not permitted, the processor 15 defines the protection status of at least a portion of the information 20 stored in the storage 13 according to the authority. It is private.

The second subsequent operation is as follows: as long as the authority of one of the electronic device 9A, the electronic device 9B and the electronic device 9C is judged as not permitted, the processor 15 will define at least a part stored in the storage 13 according to the authority. The protection status of the information 20 is private. Otherwise, that is, if the electronic device 9A, the electronic device 9B, and the electricity The authority of the child device 9C is determined to be permitted, and the processor 15 defines the protection status of the at least part of the information 20 stored in the storage 13 as public according to the authority.

The third subsequent operation is as follows: if most of the rights of the electronic device 9A, the electronic device 9B, and the electronic device 9C are determined to be permitted, the processor 15 will define at least a part of the information stored in the storage 13 according to the rights. The protection status of 20 is public; on the contrary, if the majority of the rights of the electronic device 9A, the electronic device 9B, and the electronic device 9C are judged as not permitted, the processor 15 defines at least one stored in the storage 13 according to the rights. The protection status of some information 20 is private.

If the protection status of at least a portion of the information 20 stored in the storage 13 is defined as public, it indicates that the at least part of the information 20 is not protected; otherwise, if at least part of the information is stored in the storage 13 The protection status of 20 is defined as private, indicating that at least a portion of the information 20 is protected. The protected at least part of the information 20 may have different protection aspects such as, but not limited to, encryption protection, hidden protection, limited read range protection, and the like. Encryption protection means that the protected at least part of the information 20 will be encrypted; the hidden protection means that the protected at least part of the information 20 will be hidden; and the restricted read range protection means that the protected at least part of the information 20 cannot be read completely.

Thus, even if the user lends the mobile device 1 to another person or loses the mobile device 1, the at least part of the information 20 stored in the storage device 13 is caused by the absence of the licensed specific electronic device. The state of protection continues to be defined as private and cannot be stolen.

For another example, the mobile device 1 may preset a rule that the processor 15 will automatically define the storage as long as the sensor 11 senses any electronic device and the processor 15 determines that the authority of the electronic device is not permitted. The protection status of at least a portion of the information 20 in the storage 13 is private. Thus, when the user uses the mobile device, if there are other people or other electronic devices at the same time, the protection of at least a portion of the information 20 stored in the storage device 13 is caused by the presence of the unauthorized electronic device. The state continues to be defined as private and cannot be stolen.
