Human body chip is an implantable medical device, which is used to monitor the physiological and health status of human body. It communicates with external devices through wireless signals, and these devices can analyze the data and give corresponding diagnosis and treatment suggestions. However, this kind of communication is encrypted, and some specific encryption algorithms are used to protect the privacy and security of users. Therefore, the sound monitored by the human body chip cannot be deciphered. In addition, the communication protocol of the human body chip is also strictly protected to ensure that the user's data will not be illegally obtained or tampered with.
