US Patent 10042680 Cross-domain data sharing with permission control

An electronic device may maintain separate OS domains associated with security permissions. The OS domain may implement separate corresponding clipboard services. A clipboard agent or clipboard mediator service may receive a clipboard data request from a first application. The clipboard agent may determine which OS domain has most recently processed a store command associated with storing data in a corresponding clipboard service of the OS domain. The clipboard agent associated with the OS domain that most recently stored content may determine whether to send the data from the corresponding clipboard service based at least in part on permissions associated with the OS domain. Security of the clipboard access may be enforced on a per domain basis. Access to clipboard content may be mediated at the time of the request without a need to share data prior to the request.
