Abstract
The techniques herein provide for “time-shifting” of intercepted system calls to enable a one-to-many (1:n) or a many-to-one (n:1) mapping of intercepted-to-real system calls. Any action that needs to be applied on the logical boundaries of the data (instead of the physical boundaries) presented upon system call interception spools (buffers) the data before taking the action and then unspools the result when finished. The action may be quite varied, e.g., examining the data, redacting the data, changing the data, restricting the data, processing the data, and updating the data, among others. The technique may be implemented in a database access control system.
