IOCTL_HID_ENABLE_SECURE_READ IOCTL (hidclass.h)
The IOCTL_HID_ENABLE_SECURE_READ request enables a secure read for open files of a HID collection. Only a "trusted" user-mode application (an application with SeTcbPrivilege privileges) can successfully use this request. Kernel-mode drivers have SeTcbPrivilege privileges by default, but user-mode applications do not.
A client uses an IOCTL_HID_DISABLE_SECURE_READ request to cancel an enable secure read request.
For information about how to use enable and disable secure read requests to enforce a secure read for a collection, see Enforcing a Secure Read For a HID Collection.
