US Patent:

7865935, Jan 4, 2011

Filed:

Jan 17, 2007

Appl. No.:

11/653902

Inventors:

Minoru Harada - Kobe, JP
Hiroyuki Watabe - Kobe, JP
Masaru Kamino - Rancho Palos Verdes CA, US

Assignee:

Fujitsu Ten Limited - Hyogo

International Classification:

H04L 9/00

US Classification:

726 2

Abstract:

When an electronic apparatus is forcibly put into an inoperable state by theft, the inoperable state is canceled using a code from a dealer, without carrying the electronic apparatus into the dealer. After electric power is supplied again, a CD reproduction apparatus is used to playback a CD, and TOC information is used as a code C. When code C is identical to an authorized code A the electronic apparatus is made operable. To cancel the inoperable state after the number of inconsistencies becomes 10 or more, a code A is notified to the dealer. The dealer carries out a calculation using the code A and a result B of the calculation is notified to the user. An individual code calculating means carries out the same calculation as the above-mentioned calculation and obtains calculation result B When calculation result B coincides with calculation result B the inoperable state is canceled.

US Classification:

340568100, 709224000

Abstract:

In the event that an electronic apparatus having a security function is forcibly put into an inoperable state because electric power is shut off once by an operation equivalent to theft, the inoperable state can be canceled by using a code notified by the dealer by telephone, without carrying the electronic apparatus into its dealer. After electric power is supplied again, the vehicle-mounted compact disc (abbreviated as CD) reproduction apparatus is used to play back a CD, and its TOC information is used as a judgment identification code C. When the code Cis identical to the authorized identification code A, the electronic apparatus is made operable. In order to cancel the inoperable state after the number of inconsistencies becomes 10 or more, the individual code Aof an EEPROM is indicated and notified to the dealer. The dealer carries out calculation by using the individual code A, and a result Bof the calculation is notified to the user. The user inputs the calculation result B. Individual code calculating means carries out the same calculation as the above-mentioned calculation and obtains the calculation result B. When the calculation result Bcoincides with the calculation result B, the inoperable state can be canceled.
