[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the actual application process of the physical locking device, when the interface of the hard disk body establishes physical connection with the encryption security assembly, the system enters the security protection state.In the data writing stage, the encryption security assembly adopts advanced real-time encryption algorithm, and original plaintext data is dynamically converted into high-strength ciphertext data, and is written into the hard disk storage medium synchronously, and conversely, in the data reading process, the component verifies the user right through the security authentication process, and then calls the corresponding decryption engine to restore the ciphertext data to the available plaintext data, and the end-to-end encryption mechanism effectively prevents the potential risk of data in the static storage and dynamic transmission process.

[0013] In the physical security protection aspect, when the hard disk body is separated from the device due to abnormal situation, the detection head of the precision design loses the physical contact with the hard disk immediately, at this time, the elastic potential energy of the pre-press spring is released rapidly, and the detection slider is pushed to slide along the guide rail, and this mechanical displacement triggers two key safety responses, first, the convex structure at the rear end of the detection slider is separated from the high-sensitivity trigger unit of the detection assembly, and the clear disconnection signal is generated, and second, the circuit system of the detection assembly generates the digital alarm signal immediately, and is transmitted to the monitoring computer through the special communication interface.When the computer system receives the signal, a multi-level alarm protocol is started, including but not limited to: triggering the sound and light alarm device, sending the short message / email notification, displaying the alarm information on the monitoring interface, etc.The fast response mechanism ensures that the safety personnel can find the abnormality in the shortest time, and takes the corresponding disposal measures according to the emergency plan, and effectively prevents the data leakage risk caused by illegal disassembly or accidental falling.
