  • Another alternative is to store the data in encrypted form on the respective storage medium.
  • the files stored on the storage medium can be encrypted individually or the entire files as a whole.
  • US Pat. No. 6,804,699 discloses a system and a method for preventing unauthorized access to such a device.
  • the unauthorized accesses occur mostly when the mobile device has been stolen or lost.
  • the authorized user registers the device on a central website within a database and deposits a unique identification pattern, such as a serial number. If the device has been lost or stolen, this information will be entered on this website by the authorized user. If the device is unlawfully used by an unauthorized user after the loss has been registered, the mobile device has the property of always transmitting its corresponding identification pattern via the Internet. This allows the device to be located. Also corresponding data could be transmitted in this way.
  • this method and the device has the disadvantage that any unauthorized person can access the corresponding data. If this uses a stand-alone host, so there is no connection to a web database, so that no corresponding localization can be determined.

  • a storage medium with a storage unit, a Universal Serial Bus (USB) interface for accessing the contents of the storage unit and an input device is known.
  • the input device has a fingerprint sensor for authenticating a user.
  • the read and write access to the memory contents is usually locked and the lock is released only by authenticating a user who has previously been registered.
  • This has the advantage that when a loss of such a storage medium on the Storage medium stored data can not be read by any third party.
  • the fingerprints necessary for the legitimate users are stored on a memory of the host. As soon as the authentication takes place, a comparison is made between the fingerprints stored on the host and the actual fingerprint.
  • a signal indicating this will return to an access and monitoring unit and release the readout of the data.
  • a special program is needed that is installed on the host and called when the storage device connects to the host.
  • a disadvantage of the storage unit described above is that a hardware element is additionally provided for the storage medium, which is not directly attachable to a small USB stick.
  • the fingerprint solution is a very sensitive design for detecting the surface structure of the finger, so that these portable devices are exposed to the environmental influences and the other mechanical processing.
  • the detection field can be scratched, so that the recognition of the stored finger is considerably more difficult and is assigned a high error rate.
  • the fingerprint sensor is to be arranged inside the housing of the mobile device and to be released by a sliding mechanism. Since this is only possible to a limited extent due to the existing size relationships, an electrical cable is connected to the fingerprint sensor, which in turn forms a separate element. Again, moving parts are provided, the for daily use rather lead to a vulnerability of the mobile device.
  • the object of the invention to provide a mobile device with a storage medium, the code-dependent releases the stored data, the release should be independent of a host.

After successful verification, a connection to a host is established.
  • the envisaged connection element for example a USB interface, then establishes a corresponding connection to a host. If no release takes place, the USB interface is not recognized by the host, so that no data transfer can take place.

  • Joggles or select wheels, jumpers or dip switches can also be used as a communication point between the user and the mobile device.
  • joggles and select wheels have the property of entering a plurality of code numbers on an input element and confirming them by pressing the input element.
  • a further preferred embodiment provides that the mobile device has its own energy supply.
  • This power supply can be provided to design the input device electronically, so that the release of the readout of the elements can not be done mechanically but electronically.
  • An additional power source also has the advantage that the mobile device may include one or more memories, with a memory provided to operate, for example, an MP-3 player. A correct identification of the code, which is entered by a user, can be confirmed optically and acoustically, for example.
  • One way is to interrupt the electrical connection between the connecting element and the controller or device by means of an input element in the form of a switch. Only when the code number is set correctly is this electrical connection made between the connecting element and the controller. If the connection element is connected to an interface and thus to a host, the data transmission can take place. Thus, the operation of this embodiment corresponds to a simple switch, wherein the switch is actuated by entering the correct code. A significant advantage of the invention is thus that no power supply is needed.

Abstract

L'invention concerne un dispositif mobile pour mémoriser et extraire des données et des informations similaires par le biais d'un ordinateur central. Ce dispositif mobile peut se présenter sous forme de clef USB ou de mémoire USB, mais également sous forme de carte de circuit mobile. Afin d'éviter tout accès illicite auxdites données mémorisées, le dispositif (1) selon l'invention présente un dispositif de saisie (6) qui présente la propriété de permettre la saisie d'un code, qui est comparé dans le dispositif mobile (1), avec un code en mémoire. Les données ne peuvent être transmises à un ordinateur central par l'intermédiaire d'un élément de connexion (3), qu'après établissement de la conformité du code. Ce système permet d'assurer la sécurité et la libération de données indépendamment d'un ordinateur central. La libération peut s'effectuer indépendamment d'un ordinateur central et de toute autre unité de visualisation. La libération codée peut également intervenir aussi bien mécaniquement qu'électroniquement.
