FR2652664A1 - Portable device for visual recognition with electronic display pattern - Google Patents

Abstract

Electronic system for visual recognition built into a portable medium, allowing manual or automatic identification of the carrier and capable of being used for access control, for security, for recognition, and enhancing the use of the bankers' card. The digitized photograph of the owner is inserted into the non-volatile memory of the microcontroller or of the specialised circuit (2) via the input interface (1). The display on the liquid-crystal screen (4) is performed manually by means of the control interface (3). When the portable medium is inserted into an external reader (5) equipped with a visual-display screen (6), the control interface (3) signals to the central unit (2) to address the information necessary for this display.

Description

DEFINITION:
The present invention relates to an electronic recognition system
visual integrated in a portable support, allowing the identification of the
carrier.

Portable access control, security, or card systems
are currently based on the storage of codes
more or less complex alphanumeric.

Identification is carried out when there is a match between the code
read by the reader and that indicated by the carrier.

The inviolability of the system is not total because one can read with a
computer system the code stored in the medium.

The novelty of our invention is to memorize the
photo of the owner of the support and to be able to display it on
a liquid crystal screen incorporated into the support, as well as the
display on the screen of an external reader (micro-computer, minitel.) The operation is as follows:
The owner's photograph is transformed into digital values
by an image digitization system associated with a computer or microcomputer. These numerical data are entered in the
non-volatile memory of the microcontroller or specialized circuit (2) by the input interface (1).

The display on the liquid crystal display (4) is carried out by
via the manual baleen control interface (3).

When the portable support is introduced into an external reader (5) equipped with a display screen (6), the control interface (3)
tells the central unit (2) to send the necessary information
to this display.

When programming the memory the software performs a procedure
security prohibiting any new programming by an external system, which guarantees inviolability.

The use of the portable support for automatic control can be
compare the image stored in memory with that taken by the control system. If there is a match, the system allows
processes for which it was designed (access control, security,
pattern recognition and improved job security
bank card, etc.).

Claims (1)

CLAIM. Electronic visual recognition system integrated into a portable support, allowing the identification of its owner, comprising a microcontroller or a specialized circuit (2) with an integrated non-volatile memory and write-protected after programming, in by the input interface (l), in which the photograph of the owner has been introduced in the form of digital data, and which can be displayed via the control interface (3) either on an integrated liquid crystal screen (4) to the portable support, either automatically on a display screen (6) by means of an external reader in order to make more efficient and more secure the portable supports coded for controls, access, security, card banking, etc.
