When developing a HarmonyOS application, a developer receives the following product request: If a user...

The developer can do this with the help of DVID, as the application can access and manage distributed devices based on the DVID

The developer can use the UUID to do this, because the app can uniquely identify the same device with the UUID during its lifetime

If the developer uses the UUID to achieve the above requirements, the UUID flag will still exist after the application is uninstalled

If the developer uses the DVIDto achieve the above functions, the DVID is strongly associated with the HarmonyOS account and application information, so it can prevent other applications from accessing the current application data
