Device and method for controlling access to computer peripherals
First Claim
1. Device for sharing and controlling access to peripherals for a computer system comprising a central processor (CPU) and at least one input/output peripheral having a physical control interface accessible to the central processor, characterised in that said device has:
- means for the faithful reproduction, in the form of a virtual interface, of the physical interface of at least one peripheral, means of interception, by said virtual interface, of all the requests and data exchanged between the central processor and the peripheral, controlled by a pre-determined application executed in the system, means of possible modification of said requests and data intercepted according to at least one pre-determined criterion.

Abstract
The invention concerns a device for sharing and controlling access to peripherals for a computer system comprising a central processor (3) and at least one input/output peripheral (6, 9, 10) having a physical control interface (6A, 9A, 10A) accessible to the central processor (3),
characterised in that said device has:
means for the faithful reproduction, in the form of a virtual interface, of the physical interface of at least one peripheral,
means of interception, by said virtual interface, of all the requests and data exchanged between the central processing unit (3) and the peripheral, controlled by a pre-determined application executed in the computer system,
means of possible modification of said requests and data intercepted according to at least one pre-determined criterion.

16. Method of sharing and controlling access to peripherals for a computer system comprising a central processor (CPU) and at least one input/output peripheral having a physical control interface accessible to the central processor, characterised in that it includes:
-
a step of reproducing, in the form of a virtual interface, the physical interface of at least one peripheral, a step of interception by said virtual interface of all the requests and data exchanged between the central processor and the peripheral, controlled by a predetermined application executed in the system, a step of possible modification of said requests and data intercepted according to at least one predetermined criterion. - View Dependent Claims (18, 20, 21, 22, 23, 24, 25, 26)
