A method and system for determining the extent of deterioration of a bill includes generating transmitted and reflected light images. The reflected and transmitted light intensities of the transmission and reflection light intensity images are used to determine one or more disorder curve lengths for each image of the bill. Each disorder curve length is compared with a corresponding predetermined disorder curve length for a corresponding image of a reference bill to generate an evaluation factor. The positions of the evaluation factors on an evaluation map indicate the extent of deterioration of the bill.

A method and apparatus for dynamic assigning I/O device in virtual machine system, the virtual machine system comprises a service OS, a hypervisor and at least one guest OS. The service OS contains a device model module, the device model module providing an access platform for I/O device to the guest OS. The guest OS access the device model module through the hypervisor. One device state module for dynamic reflecting the device's state is increased in the device model module, the device state module dynamic altering the register condition of the device in hardware space. It is possible to dynamic control the access to I/O device by the guest OS by using the control panel in the service OS to dynamic alter the device's state in the device state module. One agent module is increased in guest OS, for altering the device's state in guest OS anytime based on the change of the device state.

The present invention provides a system and method for hardware access control comprising a virtual machine system including a client operating system, a virtual machine monitor and a hardware device, the system further comprises: an access control module provided in the virtual machine monitor and configured to send an authorization request via a network after intercepting a device access instruction from the client operating system; and an authorization management server configured to receive the authorization request from the access control module, judge whether the authorization request satisfies a predetermined authorization strategy and feed back a response corresponding to the authorization request to the access control module; wherein the access control module determines whether the client operating system is permitted to access the hardware device based on the feedback from the authorization management server. With the present invention, the access to the hardware device from the client operating system can be effectively controlled, and thus legal data copy can be guaranteed while prohibiting any illegal data copy.
