Conditional access method and device
First Claim
1. A conditional access device, intended to be used in liaison with host electronic equipment, made up of a peripheral pointing device incorporating at least one coupler for a microcircuit card characterized in that there are personal information acquisition means particular to each user, in that personal information is locally compared with information stored in the microcircuit card without this personal information being transmitted to the host electronic equipment, and in that the personal information acquisition means are constituted by a device for showing a display on a virtual screen of the host electronic equipment and also by a virtual keyboard having graphical representations with a layout that varies in a random way with each activation, so that personal information acquisition is carried out by graphical representation pointing with validation when a position of the peripheral pointing device is on the graphical representation and processing of pointing information with validation on the virtual screen is implemented exclusively in the conditional access device.

Abstract
A conditional access device for use in connection with a host electronic equipment. The device includes a pointer peripheral containing one or more integrated circuit card coupler units. In addition, it also includes a device for acquiring personal information about a user. The personal information is locally compared with information stored in the integrated circuit card without passing through the host equipment.

15. A securization process for access to host equipment by setting into operation a conditional access device, characterized in that certain functions at least of the host equipment are only accessible after capture, by a user, of personal information which conforms to information recorded on a microcircuit card and verification of conformity between the personal information and the information recorded on the microcircuit card is realized by a peripheral device linked to the host equipment, without the personal information being transmitted to the host equipment, and further characterized in that all information and commands are transmitted in a framework of a communication protocol in wave form constituting a whole, made up of fields each formed by a coded sequence having a predetermined number of bits, each frame incorporating an identification field (FID) and at least one of the following fields:
- a pointing information field; and
a field of information relative to a secured device for storage, management and execution of a security application.
- a pointing information field; and
-
16. A process of secured data transactions comprising the steps of comparing a user'"'"'s personal information and data contained in a microcircuit card, and setting in operation a conditional access device, characterized in that a control step is carried out by the conditional access device which forms a protective barrier against computer fraud, and further characterized in that all information and commands are transmitted in a framework of a communication protocol in wave form constituting a whole, made up of fields each formed by a coded sequence having a predetermined number of bits, each frame incorporating an identification field (FID) and at least one of the following fields:
- a pointing information field; and
a field of information relative to a secured device for storage, management and execution of a security application.
- a pointing information field; and

17. Process for management and execution of security applications within host interactive electronic equipment equipped with peripheral equipment, said electronic equipment comprising a screen and means for allowing local and remote execution of applicative software and having a graphical user interface with visual objects which a user can act upon manually by activating the peripheral equipment, characterized in that said process includes a communication protocol between a part at least of the applicative software and a secured device for storage, management and execution of a security application, cooperating with at least one coupler for receiving a microcircuit card incorporating a distribution application of the security applications, said communication protocol being an extension of a communication protocol specific to a pointing means for the peripheral equipment, and in that all information and commands are transmitted in a framework of the communication protocol in waveform comprising a whole, made up of fields each constituted by a coded sequence having a predetermined number of bits, each frame incorporating an identification field (FID) and at least one of the following fields:
-
A pointing information field; and A field of information relative to the secured device. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
