Definitions
- the invention relates in particular to a method for documenting service measures on a motor vehicle using an electronic memory according to the preamble of the corresponding main claim.
- the invention is particularly concerned with the task of providing a reliable method for documenting service measures that have been carried out on a motor vehicle using an electronic memory.
- Advantageous refinements of the invention are specified in the dependent claims.
- An essential aspect of the method according to the invention is to generate a hash value of an entry in a first step, which has at least one concrete service measure, preferably in plain text.
- This service measure involves, for example, an oil change, the replacement of a wearing part and / or a vehicle inspection.
- the hash value of the entry is encrypted with a personal key as part of a public key process and assigned to the entry or stored with it in the electronic memory.
- the entry for the service measure preferably in plain text, the encrypted hash value and a certificate of the key holder are written into the electronic memory or stored therein.
- the certificate preferably has at least the public key that is complementary to the personal key and further details of the key holder.
- the encrypted hash value is stored in such a way that the encrypted hash value cannot be exchanged for another hash value.
- a further essential aspect of the invention consists in that the hash value for the entry, which specifies the specific service measure, is generated again in a fourth step in order to check the authenticity of the entry.
- the encrypted hash value written into the electronic memory is decrypted using the public key specified in the certificate.
- the decrypted hash value is compared with the newly generated hash value. If both hash values match, the entry is considered to be unadulterated.
- the hash value is a bit cross-sum, in particular a bit cross-sum of the entry for the specific service measure.
- This can be implemented in a technically uncomplicated manner, e.g. by a device in the motor vehicle that generates a hash value of the entry, such as in particular a bit checksum.
- the current date and the current mileage of the motor vehicle at the time of the service measure and the hash value for at least the entry, the date and the mileage in the electronic Memory is saved.
- the hash value at least for the entry that designates the service measure, the date and the mileage, prevents manipulation of the data characterizing the condition of a vehicle in a simple but very effective manner.
- the electronic memory in the motor vehicle in particular in a control device of the motor vehicle, and / or in a removable mobile data carrier in the motor vehicle, such as in particular a chip card, and / or in a Device external to the vehicle, in particular at the manufacturer of the motor vehicle, is provided.
- an electronic memory which is arranged in the motor vehicle, has the advantage that it remains in the vehicle even when the vehicle is sold and / or each time the vehicle is visited to save the service or maintenance measure by a service engineer. Technician is available in the workshop.
- the content of the electronic memory can be used, for example, for the vehicle owner via a display provided in the vehicle or a vehicle computer for control and / or other purposes, e.g. in a sales conversation about the vehicle.
- the advantage of using a chip card is that the documentation of service measures or the content of the electronic memory outside the vehicle, e.g. can be viewed on a screen on the home PC using a chip card reader.
- the service measures are documented in an embodiment of the invention, preferably immediately after the service measure, in a device external to the vehicle, in particular at the manufacturer of the motor vehicle. This ensures that the two hash values are checked by the vehicle manufacturer or an institution commissioned by him, in a safe and reliable environment.
- one embodiment of the invention provides that the service measure, the date of the service measure, the current mileage at the time of the service measure and the certificate are stored in plain text in the electronic memory. With this, it is already possible to document service measures to a large extent in a way that cannot be falsified.
- the generation and / or encryption of the hash value using the personal key of a workshop and / or a service Technician is carried out, which preferably uses a chip card, in which at least the personal key is preferably stored securely against unauthorized reading.
- a complementary public key and a certificate with which a so-called trust center confirms that the public key is assigned to the key holder specified in the certificate ensure the authenticity of the data of the service measures in a reliable manner. It can therefore be determined without any doubt who has confirmed what, when, in which workshop or the like on the vehicle.
- the content of the electronic memory in particular the service measures stored in the electronic memory, on a screen provided in the motor vehicle and / or on a screen located in a workshop or at a vehicle dealer and / or be displayed on the screen of a PC in the home.
- the documentation can be displayed in a flexible manner whenever it is needed.
- the renewed formation of the hash value, the decryption of the encrypted, already formed hash value and the comparison of the two hash values in the motor vehicle, and / or in the workshop or at is carried out by the vehicle dealer and / or by the vehicle manufacturer or an organization working for him and / or by the PC in the home.
- the invention further enables the provision of a device for documenting service measures on a motor vehicle using an electronic memory, in which the device carries out a method according to one of the preceding method claims.
- the invention makes it possible to provide a computer program product for documenting service measures on a motor vehicle using an electronic memory, in which the computer program product prompts the execution of a method according to one of the preceding method claims.
