This invention discloses a method for maximizing the task completion rate of a UAV-assisted multi-MEC server, primarily addressing the problems of severe channel fading and limited computing resources of a single MEC server in existing technologies. The method includes: 1) constructing a UAV-assisted multi-MEC server network system model; 2) employing a time-division multiple access (TDMA) protocol, where users offload part of their task input data to the UAV, and the UAV offloads part of its unfinished task input data to multiple ground base stations for computation; 3) finding the optimal task completion rate, CPU computing frequency, transmission power, offloading decision, and UAV trajectory by maximizing user task completion rate and minimizing system energy consumption; and 4) optimizing system operating parameters based on the optimization results. This invention effectively improves network computing resources, achieves stability in environments with high computational workloads, and reduces energy consumption for both UAVs and users, making it applicable to edge computing systems.

In one embodiment, a method includes transmitting, by a privacy component, to a first server, a privacy communication request consisting of device data and server data associated with a second server, receiving, by the privacy component, from the first server, a privacy communication string tagged to the second server, wherein the privacy communication string and a privacy communication string record are generated in response to the privacy communication request identifying the second server based on the server data, transmitting, by the privacy component to the second server the privacy communication string, configured to be transmitted to the first server as an approval request, identifying the second server as a requesting server associated with the secure exchange, and receiving, by the privacy component, from the second server, an indication that the approval request was validated based on the requesting server matching the second server identified in the privacy communication string record.

A system for changing a user's password across multiple servers accesses a master server within a multiple-server system architecture. The master server has a user database and a connection database. The system accesses a target server via a remote log in from the master server. The target server includes a user database and a connection database. The system changes an existing password within the user database of the target server. The system reads the connection database of the target database to determine which additional servers the target server connects to. The system updates the connection database of the target server with updated connection information. The system can alternatively receive a file upload containing information pertaining to which servers the target server can connect to, and subsequently update the connection database of the target server. This process is repeated for multiple servers and / or user accounts to perform mass password updates.

The application discloses a multi-terminal non-susceptible login access method based on tokens and device fingerprints and an electronic device, and relates to the technical field of electronic devices. The method comprises the following steps: when a first user accesses multiple servers through a first terminal, the first terminal obtains a first token for accessing a first server according to a device fingerprint of the first terminal and login information for the first server, and stores the device fingerprint of the first terminal in a user device fingerprint set of the first user; the first terminal generates a second token for accessing a second server according to the device fingerprint of the first terminal and the fact that the first token exists in the user device fingerprint set of the first user; the user device fingerprint set comprises device fingerprints of part or all terminal devices corresponding to part or all login information of the user, and the device fingerprint is a unique identifier of the terminal device. The application can realize non-susceptible login and access of the user in a multi-terminal multi-server system.
