Abstract
Embodiments of the invention are generally directed to systems, methods, devices, and machine-readable mediums for implementing gesture-based signature authentication. In one embodiment, a method may involve generating a data protection policy from an un-trusted software environment to govern access to protected data stored in memory in the local computer system. Then the method maps the data protection policy to an enforceable system-level data protection policy managed by an Information Flow and Tracking Protection (IFTP) logic. Next, the method flags the first memory page containing the protected data. Finally, the method enforces the generated data protection policy for the first memory page containing the protected data using the IFTP logic and the enforceable system-level data protection policy.
