System and method for controlling access to mobile devices
View Patent ↗A system and method for controlling access to, and especially protecting against unauthorized attempts to provide input to, e.g., program, or elicit output from, a vehicular or other mobile device ( 14 ), such as an electronic control unit (ECU), wherein a determined location of the device ( 14 ) or an inputted user acknowledgment provides a basis or an additional basis for allowing or denying the attempt at access.
1. A method of controlling an attempt to access an electronic control unit ( 14 ), the method comprising the steps of:
(a) detecting at least one attempt to access the unit ( 14 ) at a gateway coupled to the device, and temporarily denying the attempt;
(b) determining a current location of the unit ( 14 ), and communicating the current location to the gateway;
(c) electronically comparing the determined current location to a database of authorized locations ( 18 ); and
(d) permanently denying the attempt to access the unit ( 14 ) if the determined current location does not match an entry in the database of authorized locations ( 18 ).
2. The method as set forth in claim 1 , wherein the unit ( 14 ) is a vehicular device.
3. The method as set forth in claim 1 , wherein the access involves providing input to the unit ( 14 ).
4. The method as set forth in claim 3 , wherein the access involves programming the unit ( 14 ).
5. The method as set forth in claim 1 , wherein the access involves eliciting output from the unit ( 14 ).
6. The method as set forth in claim 1 , wherein an attempt at a first type of access results in comparing the determined current location with a first set of entries in the database of authorized locations ( 18 ), and an attempt at a second type of access results in comparing the determined current location with a different set of entries in the database of authorized locations ( 18 ).
7. The method as set forth in claim 6 , wherein the first type of access involves programming the unit ( 14 ), and the second type of access involves eliciting output from the unit ( 14 ).
8. The method as set forth in claim 6 , wherein the first type of access involves eliciting a first type of information from the unit ( 14 ), and the second type of access involves eliciting a second type of information from the unit ( 14 ).
9. The method as set forth in claim 1 , further including the step of requiring satisfaction of at least one other substantially independent access-control mechanism before allowing access to the unit ( 14 ).
10. The method as set forth in claim 9 , wherein said other mechanism is an electronic password or cryptographic access-control mechanism.
11. The method as set forth in claim 1 , wherein the attempt to access is wireless.
12. A method of controlling an attempt to access an electronic control unit ( 14 ) in a vehicle ( 10 ), the method comprising the steps of:
(a) autonomously detecting an attempt to access the electronic control unit ( 14 ), so as to program, elicit output from, or download content to the unit ( 14 ), and temporarily denying the attempt;
(b) autonomously determining a current location of the electronic control unit ( 14 ) at the vehicle ( 10 );
(c) storing a database of authorized locations ( 18 ) at the vehicle ( 10 ), and electronically comparing the determined current location to the database of authorized locations ( 18 );
(d) permanently denying the attempt to access the electronic control unit ( 14 ) if the determined current location does not match an authorized location entry in the database of authorized locations ( 18 ); and
(e) permanently denying access to the unit ( 14 ) by at least one other substantially independent access-control mechanism, if the attempt does not also satisfy the mechanism.
