Users access the cloud phone through a cloud phone client with security protection mechanisms, and use the application through real-time encrypted video transmission and operation input. All data interaction is executed within the cloud phone system in the data isolation zone, and data does not leave the zone or land on the terminal. The system management platform can comprehensively manage and audit the application, data, and users. IOS cloud phone servers use standard x86 servers, while Android cloud phones use x86/Arm architecture servers.
