The invention relates to a node authentication method and system of a distributed AI collaborative computing system. The method comprises: a central server sends authentication instructions to each distributed node; each distributed node completes the corresponding real-time computing capability verification task according to the authentication instruction and sends a response message to the central server; the response message includes task completion time and node equipment information; the real-time computing capability verification task includes a real-time computing capability verification task and a real-time storage capability verification task; the central server receives the response message. If the time of receiving the response message exceeds the expected time, or the difference between the task completion time and the task completion time of the real node of the same device type completing the real-time computing capability verification task is greater than the preset threshold, the node is identified as a suspicious node; the central server sends authentication instructions to the suspicious node for many times and receives the response message returned by the suspicious node. If the time of receiving the response message exceeds the expected time or the difference between the task completion time and the task completion time of the real node of the same device type completing the real-time computing capability verification task is greater than the preset threshold, Then it is judged that the node is forged.
"Thin as paper and sound as chime" is the reputation of the two important characteristics of optical and acoustics of Chinese porcelain. On most online display platforms, porcelain is only displayed in two dimensions, and the sound display is relatively single. This paper studies and proposes a simulation method for visual and auditory multidimensional interaction in a distributed environment. Based on the porcelain photo acoustics of virtual simulation, in the 3D simulation porcelain model, by adjusting the intensity coefficient of the light source, the light propagation model on the surface and inside of the porcelain is established to realize the thinness and light transmittance of the porcelain. This research combines the fundamental frequency, harmonic frequency technology and volume with the 3D porcelain model, and use its structural characteristics and the principle of chime to synthesize the percussion sound of porcelain in a virtual simulation environment. The research conclusions can be applied to fields such as art online platform display.
