[0052] The flowcharts in Figures 5-6 illustrate how the schematic system 300 in Figure 3 can be operated according to a first embodiment of the present invention.

[0053] According to a first step 510 in the flowchart of FIG. 5 , the security unit 400 in the information carrier device 310 prohibits access to information and / or applications in the carrier device 310 . The disable signal may be provided from the controller 410 to the information storage unit 315 and / or the application in the carrier device 310 eg via the output connection 415 .

[0054] According to the second step 520 in the flow chart of Fig. 5, the security unit 400 in the information carrier device 310 preferably sends intermittent wireless request signals, that is, sends request signals within predetermined time intervals. Generally, transmission or reception is preferably implemented by the controller 410 instructing the transceiver 420 to transmit or receive.

[0070] The flowcharts in FIGS. 7-8 illustrate how the exemplary system 300 in FIG. 3 can be operated according to a second embodiment of the present invention.

[0071] According to the first step 710 in the flowchart of FIG. 7, the security unit 400 in the information carrier device 310 prohibits access to the information and / or applications in the carrier device 310 in a similar or identical manner as previously described in connection with step 510 in FIG. program.

[0072] A timer is then started and started in a second step 720 in a similar or identical manner as previously described in connection with step 520 in FIG. 5 .

[0073] The timer start and start in step 720 is followed by a third step 730 in which the controller 410 commands the transceiver 420 to receive a possible enable signal. If a signal is received, it is converted by the transceiver 420 and provided to the controller 410 via the input connector 412 . The controller 410 then processes the received sign...

Abstract

The invention provides for a portable device, a system comprising at least two portable devices and a method according to which at least a first portable device and at least a second portable device can be arranged so that said devices have to be located within a short distance from each other if access to the contents in said first device should remain enabled and / or access to the contents in said second device should remain enabled.

Description

technical field [0001] The present invention relates to an automatic protection system and a method of using such a system. In particular, the present invention relates to an automatic information protection system having a wireless information carrier device equipped with an enabling / disabling control function and a method for using the same A wireless control device that performs wireless communication to automatically perform enable and disable functions. Background technique [0002] The development of powerful portable devices has continued for some time. A non-exhaustive list of such portable devices are laptops, personal digital assistants (PDAs), digital notebooks, mobile phones, and even road-to-ground radios (eg, walkie-talkies), among others. These powerful devices often carry large amounts of information that must be protected from access by unauthorized users. These powerful devices may also include computer programs or other applications that must be protect...
