JP2007070999A - System for unlocking and locking key by issuing qr code from cellular phone - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To form this system under the same condition even in any expensive and high-degree authentication system when reversely stated due to being unuseful in power failure and when a portable terminal is lost by forming a key itself in a system superior in usability without becoming complicated by changing an authentication code every time when going out in an extreme instance since an information source is fixed and a device is also complicated and expensive though authentication of a safely arranging key is the highest peak in using a number, vital reaction and DNA. <P>SOLUTION: This problem can be solved by receiving a battery-driven circuit by 2 to 3 circuits as a fail-safe circuit on the fixed key side since output for reading an authentication RQ code from the cellular phone is very feeble. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

    In the present invention, a two-dimensional bar code and a QR code of a three-dimensional code are used for a medium as key authentication.

    An arbitrary combination of numbers, letters, symbols, etc. from a mobile phone or mobile terminal is converted into a QR code alone, and it is recognized as a code for authentication on a key fixed to a building or article by the issued QR code and locked And unlocked, and locks and unlocks by re-recognizing the same code.

    Mobile phones and portable terminals have built-in QR code creation applications or are stored in storage devices, through which QR codes can be freely created and issued, and those codes can be simultaneously transmitted to mobile phones and portable terminals. It can be displayed on the display.

    Cellular phones and portable terminals are provided with a barcode reader function, and a newly issued code is read and stored by an attached camera or the like so that the QR code with the same key can be shared and used.

    The fixed key has a function that first reads and stores a newly issued QR code from the display screen of the mobile terminal that issued the QR code, and locks or unlocks the same code when it is recognized. It is mechanically or electrically connected to the crane part that is mechanically or electrically connected to the crane, but the information of the authentication part can be locked and opened mechanically or electrically. . The first memory part must be done inside a fixed object. That is, in the case of a door, only the barcode-reader inside the door can be memorized. It is assumed that the outer barcode reader simply has the function of a recognition device.

    Bar codes can mainly show a large amount of complex information in a very small range, can easily issue new information, and can always ensure safety with a new code.

    A portable application that can easily issue a barcode is built in as a system, or downloaded and stored in a storage device.

    The issuance of two-dimensional barcodes is done through devices such as personal computers and these devices, and mobile terminals and mobile phones themselves could only recognize them, but the terminals incorporate or store dedicated applications. This is what gives the 2D barcode issue function itself.

    Since the portable terminal itself produces and issues information as a key, there is no need for complicated storage devices and mechanical devices such as conventional biometric authentication and fingerprint authentication for the fixed-side key.

    It is safe to issue the QR code for authentication because it is easy for the portable terminal and the key authentication can be changed every day. In addition, the combination of complicated symbols and the text itself are authenticated, so it is very difficult to duplicate and safe.

    This can be realized by incorporating an application for a mobile terminal issued and produced by a QR code. A bar code reader is installed on the fixed key side, and the machine is operated by memorizing and matching the first code.

    Since it is possible to easily create an authentication code, it can be changed to a new code whenever necessary and is safe.

    Hereinafter, embodiments of the present invention will be described with reference to FIGS.

    Any place where it is important to ensure safety when locking places that are easy to see in social life.

    This is effective not only for buildings and boxes, but also for vehicles, equipment, and robots.

2 is a general system diagram of a two-dimensional barcode key system issued by a mobile terminal. The path | route system figure of the issue of the two-dimensional barcode in a mobile telephone. A figure in which QR codes are converted into barcodes by identifying letters, pictograms, figures, etc. The figure which memorize | stores a code from a portable terminal taking a door as an example.

Claims (7)

    A key that can be opened and closed using a barcode such as a two-dimensional barcode or a three-dimensional code as a medium.     The machine used as the key for the barcode medium must be a mobile terminal such as a mobile phone.     The mobile terminal has a bar code reader function, and after the code for identification as a key medium is freely issued, the data is displayed on the display so that the bar code reader of the fixed key can correctly recognize the data. Things.     Keys on the side that is fixed to buildings and objects that require locking have bar code readers on the front and back or both outside and inside.     The key according to claim 4 has a function of simultaneously recognizing information from a portable terminal and mechanically or electrically opening and closing the key.     In the terminal of claim 4, the part for recognizing the bar code and the part for mechanically locking and opening and closing are integrated and separate, but mechanically and electrically connected and interlocked.     The method of passing data from the mobile terminal to the fixed lock is to authenticate the QR code figure displayed on the display of the mobile terminal on the fixed key side.
