[0002] In recent years, with the development of science and technology, cloud computers have been widely used in many fields such as remote office, online education, video conferencing, and gaming entertainment due to their convenience, efficiency, and resource saving. Cloud computers generally use embedded Linux operating systems, which concentrate a large number of computing tasks on cloud servers. Users only need to connect to the network to access media resources such as images, sounds, and videos stored on cloud servers, which effectively saves the performance configuration of users' local hardware devices, as well as resource overhead such as hardware updates and maintenance, and reduces the cost of use and maintenance. However, due to the insufficient privacy protection measures of cloud computer hardware devices, the risk of user data being stolen by third parties is also greatly increased. For example, the lack of privacy protection design leads to privacy violations such as being easily monitored and recorded by third parties when users use cloud computers. In addition, when using cloud computers, users may also need to stay connected for a long time to ensure the continuity of services such as video conferencing and online education, thereby increasing the power consumption of the battery and affecting the endurance of cloud computers.
