System and method for securing computer-executable program code using task gates

摘要

A system, method and apparatus including a security-related computer-executable module, preferably embodied as software that operates in combination with a computer to secure arbitrarily located application program code. The system is capable of performing the method of inserting or placing at a location in a computer program defining a computer-executed task, security-related computer-executable information denominated as a task gate defining predetermined security conditions that must be meet to proceed past the task gate. The task gate is invoked when encountered during execution of the computer program. The gate is used to determine whether the predetermined security conditions have been met before allowing any further computer execution of the program.
