  • System and method for proxy-based data access mechanism in enterprise mobility management
    Patent number: 10776520
    Abstract: A system and method include a shield application executing on a processor. The shield application can convert a business application to provide data isolation between the business application and personal applications, and data sharing between the business application and other business applications, e.g., in the bring-your-own-device and enterprise mobility management scenarios.
    Type: Grant
