Abstract
A security system unlocks a locked state, which limits a use of a vehicle device attached to a vehicle, by inputting a preset genuine password. The security system may generate key information by converting the genuine password based on a predetermined rule. The key information is used for generating an alternative password that unlocks the locked state instead of the genuine password. The security system may generate the alternative password based on the key information. The security system may unlock the locked state when the alternative password is input.
Claims5
A security system comprising:
- a vehicle device including a first processor, the vehicle device configured to be attached to a vehicle and configured to be unlocked from a locked state that limits a use of the vehicle device by inputting at least one of a preset genuine password and an alternative password;
- and
- a management device including a second processor, the management device configured to communicate with the vehicle device, wherein
- the first processor is configured to generate key information by converting the preset genuine password based on a predetermined rule, and wherein
- the second processor is configured to generate the alternative password based on the key information and to transmit the alternative password generated by the second processor to the first processor, and wherein
- the first processor is further configured to store the alternative password generated by the second processor in a memory and to unlock the vehicle device from the locked state when the alternative password input to the vehicle device matches the stored alternative password generated by the second processor.
A vehicle device attached to a vehicle and configured to unlock from a locked state that limits a use of the vehicle device by inputting at least one of a preset genuine password and an alternative password, the vehicle device comprising:
- a processor configured to
- generate key information by converting the genuine password based on a predetermined rule,
- receive the alternative password generated by a management device based on the key information, the management device transmitting the alternative password to the vehicle device,
- store the alternative password generated and transmitted by the management device, and
- unlock the vehicle device from the locked state when the stored alternative password generated and transmitted by the management device matches the alternative password input to the vehicle device.
A computer-readable non-transitory storage medium storing a security program, the security program comprising instructions executed by a processor of a vehicle device attached to a vehicle for unlocking the vehicle device from a locked state that limits a use of the vehicle device by inputting at least one of a preset genuine password and an alternative password, the instructions comprising:
- generating key information by converting the genuine password based on a predetermined rule;
- receiving the alternative password generated by a management device based on the key information, the management device transmitting the alternative password to the vehicle device;
- storing the alternative password generated and transmitted by the management device;
- and
- unlocking the vehicle device from the locked state when the stored alternative password generated and transmitted by the management device matches the alternative password input to the vehicle device.
