Definitions

  • the invention is based on a method for recognizing the Authorization to use electrical devices and car radio devices and / or mobile devices according to the genre of the independent Claims.
  • Car radio devices are already known which provide theft protection have, which leads to the fact that after separation of the Car radio from the vehicle power supply the function is interrupted. That from the power supply removed device can only be properly put back in Be put into operation if a device-specific user code is entered. Recently this has become device-specific User code by inserting a chip card in realized the read / write unit provided for this.
  • the user When purchasing such a device, the user receives a special chip card with which his device can be put into operation. There is also the option of purchasing another special chip card and storing the code of this card in the device. If these two device cards are not available at the moment, or if the cards have even been lost, the car radio could no longer be put into operation without problems. The It is not possible to "learn" the code of other chip cards.
  • the independent claim has the advantage that any chip or code card as a key can be used for the electrical device. This allows the Users of the device, in the event of loss of their original chip card, choose any replacement card that also as proof of the authorization to use his device serves. Any data field on the card is read out and saved as a new, additional user code in the device.
  • the user can choose any one second card can use another user code write to the device, e.g. one already with him existing chip card that has other functions.
  • The has the advantage that there is no additional chip card must be introduced, but that from what already exists If a card was selected and an additional card was selected Code can be extracted.
  • second chip card for a personalized card, e.g. is a Euro check card or a mobile network card.
  • the user advantageously has the possibility of additional Maps, or data fields on them as define additional user codes. However, appears it is advantageous if the number of user codes is limited.
  • the user codes should be encrypted Form. This prevents an unauthorized person User can read code numbers from the device.
  • Chip cards can also advantageously be read out without their approval as a code card.
  • the code-protected car radio according to the invention, and the mobile radio device advantageously has Read / write unit that is capable of different Read chip card types and pass on their data fields. The user of the device, whether the contents of the data fields are saved or to be shown on a display.
  • FIG. 1 shows an embodiment of a car radio.
  • FIG. 1 shows a car radio device 5 according to the invention.
  • the device 5 has a read / write unit 7 for chip cards 6, which is connected via a processor 8 to a memory 9 and a display 10.
  • the device has a circuit, not shown here, for interrupting its function, which is connected to the processor 8.
  • the user operates the device via an input unit 14 connected to the processor.
  • the chip card 6 has a microprocessor 12 with integrated memory and a contact surface 13 required for communication with the read / write unit.
  • a suitable software of the processor allows contents of taught-in chip cards to be shown on the display 10.
  • the user inputs via the input unit 14 whether and which content of the chip card 11 is to be displayed in the display 10 of the device. For example, the last bookings made with cash cards can be called up. Alternatively, it is possible to call up card contents of any chip cards without the card being a code card beforehand was learned ".
  • the device 5 can also be a mobile radio device, for example for use in GSM networks or the combination of a car radio and a mobile radio receiver in a vehicle.
  • the user code taken from the chip card is compared in the device itself with the original code stored in the memory. If the two codes match, the user of the code card is authorized to put the device into operation. Any other chip card can now be taught.
  • this second chip card 11 must be inserted by the user into the read / write unit 7 of the device.
  • the device reads one or more data fields from the chip card. These data fields are then stored in the memory as new user codes. This will be any chip cards learned "and the user does not have to purchase an additional card if the original chip card is lost.
  • any chip card that only has to have an identical, contact-based interface.
  • Such cards are specified, for example, in ISO 7816 are used in various designs as health insurance cards, bank cards, cell phone cards, credit cards, etc. All these cards can be used with a suitable design of the device software For example, a health insurance number, a bank secret number, a phone number, etc. would be a new code for the electrical device. However, such codes, which are also relevant to security, should only be stored in encrypted form in order to reduce the risk of misuse.
  • the device software must be able to run the operating system to recognize the chip card and to correspond with it to allow a successful reading of the user code.
  • a certain security is to only accept such cards use a unique assignment to a user show, i.e. which are personalized, e.g. Euro check cards or cellular network cards. With an appropriate statistical risk can also be a not clearly personalized Card such as used a simple calling card will.
  • the number and type of card types allowed is not initially limited. It is safe sensible, a small selection of card types with as possible high prevalence since each supported card type an additional software effort in the device processor causes.
  • any card can be read out, for example to store a new code such as the Eurocheck number etc. in the device as an access code and user authorization, it is easy to read out and display further data stored on the card.
  • the electrical device thus also serves as a card reader, with which card contents can be read and possibly even changed.
  • the card reading function does not have to be accompanied by the simultaneous admission of a card as a code card. If the device is put into operation properly with a code card, further cards can be read out.
