With a total of 2 patents, his work focuses on enhancing the security measures that safeguard critical system processes.

Latest Patents

Yafei Zhang's latest patents include innovative methods for protecting kernel extensions and antivirus daemons in a computer. The first patent outlines a method that protects a daemon in an operating system by detecting access attempts to a plist file. When such access is detected, the operating system executes a callback function that notifies a kernel extension of the attempted access. The kernel extension then returns a value indicating that the access should be denied, ensuring that unauthorized processes cannot access the plist file. Additionally, the kernel extension has self-protection mechanisms that execute an exit function when unloading commands are issued, verifying the authorization of the application making the request.

The second patent similarly addresses the protection of antivirus daemons. It employs the same method of detecting access attempts and executing callback functions to maintain the integrity of the daemon's plist file. This dual approach not only enhances system security but also provides a user prompt for further instructions when necessary.
