Definitions
- the invention relates to a method for the lawful use of cryptocurrencies in vehicles according to the type defined in more detail in the preamble of claim 1 and a vehicle for carrying out the method.
- Cryptocurrencies such as Bitcoin, Ethereum or Ripple are used in particular to carry out anonymous transactions and for speculation.
- Such cryptocurrencies are based on the so-called blockchain technology, with all transactions carried out by the unit with cryptocurrencies being stored in the blockchain.
- the blockchain is distributed in the form of a so-called ledger to a large number of actors who perform calculations to confirm transactions that have been commissioned. These actors are also called miners. Because the ledger is distributed decentrally, it is also referred to as distributed ledger technology.
- a so-called wallet is required to carry out cryptocurrency transactions.
- This includes a public and private key, with the help of which units of the cryptocurrency can be assigned to actors.
- the public key can be compared to an account number and the private key to access permission to withdraw units of the cryptocurrency from the account.
- wallet types such as so-called hardware wallets, software wallets or paper wallets.
- a hardware wallet the private key is stored on a separate hardware device such as a USB stick. This allows the private key to be stored on a device without an internet or network connection, making it more difficult for an attacker to steal the private key.
- the paper wallet in which the private key is printed out on a piece of paper, also offers a similarly high level of security protection is kept.
- a software wallet the private key is stored on an end device such as a PC, tablet computer or smartphone, which makes it very user-friendly, but also stealing the private key, for example by reading the private key loaded unencrypted into the main memory of the corresponding device, relieved.
- the trading, possession and/or mining of cryptocurrencies is restricted or prohibited in some countries, for example due to the speculative nature of cryptocurrencies and the associated high value volatility, the preferred use by criminals such as extortion in connection with ransomware as well as due to the negative impact on the environment, due to the high power consumption during mining.
- Trading in cryptocurrencies may be permitted in some countries, but there may be special regulations for individual cryptocurrency classes or individual cryptocurrencies. This applies in particular to the initial issue of cryptocurrencies, also known as Initial Coin Offerings (ICO) or Security Token Offerings (STO).
- ICO Initial Coin Offerings
- STO Security Token Offerings
- edge computing With the integration of ever more powerful hardware components in distributed devices and an increasingly higher data transmission rate in mobile communications, such as 5G, the importance of edge computing is also increasing, whereby technical devices such as a vehicle and a toll station, for example, independently conduct transactions with each other using so-called smart contracts carry out.
- Blockchain technology can also be used here, in particular using a decentralized or centrally managed cryptocurrency.
- the applicant's DE 10 2018 006 478 A1 discloses a method for carrying out cashless payment transactions by a vehicle user. An application program that is stored on a vehicle key and includes a private digital key is used to carry out payment transactions with at least one cryptocurrency.
- the applicant's DE 10 2019 005 116 A1 discloses a method for trading cryptocurrencies.
- the method disclosed in the publication enables legally compliant trading of cryptocurrencies in countries where there are restrictions on trading cryptocurrencies.
- a computing unit in a vehicle checks planned transactions for legal compliance. The computing unit only allows transactions to be carried out that are legal in the country in which the vehicle is located.
- the present invention is based on the object of specifying an improved method for the lawful use of cryptocurrencies in vehicles, with the aid of which violations of the law can be prevented even more reliably while maintaining a comparatively high level of user convenience.
- this object is achieved by a method for the lawful use of cryptocurrencies in vehicles with the features of claim 1.
- Advantageous refinements and developments as well as a vehicle with a computing unit and a wireless communication device result from the dependent claims.
- the processing unit can arrange for a copy of the access information stored in the hardware wallet to be transmitted to a vehicle-external temporary memory before the access information is deleted from the hardware wallet.
- the method according to the invention enables the legally compliant use of cryptocurrencies in vehicles while maintaining a particularly high level of user convenience.
- the possibility of accessing at least this cryptocurrency is removed from the vehicle.
- either all units of the corresponding cryptocurrency are removed from the crypto account and/or the access information is removed from the hardware wallet so that the vehicle's processing unit can no longer use it either.
- the crypto account can, for example, be assigned to a vehicle occupant such as the person driving the vehicle or the vehicle owner.
- User comfort is ensured by the fact that the processing unit monitors the relevant country-specific legal provisions itself and, if necessary, automatically initiates or carries out the steps necessary for the legally compliant use of the cryptocurrency itself. As a result, the person driving the vehicle does not have to worry about potential violations of the law.
- the cryptocurrency can be any cryptocurrency such as Bitcoin, Ethereum, Lightcoin, Ripple or the like, or a cryptocurrency managed by a country, community of states or recognized financial institution.
- the units of the cryptocurrency are contained in the blockchain, i.e. in the ledger, which is managed decentrally or centrally.
- the ledger which is managed decentrally or centrally.
- cryptocurrencies will be developed and used in the vehicle, in which the units of the cryptocurrency are stored in the wallet itself.
- the crypto account identifier is in particular a public key, also referred to as a public key. If an actor knows the crypto account identifier, the actor can transfer units of the corresponding crypto currency to the crypto account assigned to the crypto account identifier.
- the access information is in particular a private key, also referred to as a private key, which corresponds to the respective public key identifying the crypto account identifier.
- the private key is stored in the hardware wallet in a secure manner, in particular using cryptographic encryption measures.
- the hardware wallet can be integrated into the computing unit of the vehicle or can be external to the computing unit or even external to the vehicle and can be read out by the computing unit through wired or wireless communication with the computing unit of the vehicle.
- the communication between the hardware wallet and the computing unit is preferably also encrypted. This makes it difficult to read the private key, which could allow an attacker to gain access to the crypto account.
- the processing unit communicates with the vehicle-external infrastructure.
- the vehicle-external infrastructure can be, for example, a mobile radio base station, via which the processing unit communicates with the Internet.
- transactions can be carried out with a cryptocurrency trading exchange.
- the off-vehicle infrastructure can also be edge computing-enabled devices, such as a toll station or an electric vehicle charging station. Any conceivable wired or wireless communication technology such as mobile communications, WiFi, Bluetooth, NFC or the like can be used for communication.
- the hardware wallet can also be integrated into a smartphone, for example, which enables the computing unit to be connected to the Internet via tethering.
- the third party account in the form of a trustee account and/or the temporary memory for storing the copy of the access information is managed by a service provider. It is generally possible for the third-party account to be assigned to a vehicle occupant, for example, like the actual crypto account, to the person driving the vehicle. The person concerned does not carry any access authorization for the third-party account, e.g. in the form of a private key. If the units of the cryptocurrency are then transferred to the third-party account, the person does not actually own the banned cryptocurrency, since they do not have access to the third-party account and therefore do not violate the relevant laws of the country. In order to transfer the corresponding units of the cryptocurrency back into the vehicle, i.e.
- the third-party account is managed by a service provider
- user convenience can be increased.
- position data of the vehicle can be transmitted to the service provider, whereby the service provider can arrange for the units of cryptocurrency to be automatically transferred back to the vehicle when the vehicle enters a country in which the corresponding cryptocurrency is legal.
- the service provider can be a vehicle manufacturer, for example.
- the position of the vehicle can be determined using GPS, for example. In this way, the vehicle can transmit its GPS position to the vehicle manufacturer via mobile communications.
- the memory to which the copy of the access information is transferred can also be managed by the service provider.
- Any storage system for example the e-mail inbox or the cloud storage of the vehicle occupant, can generally be used as temporary storage for storing the typically encrypted copy of the access information.
- the encryption prevents misuse. If the temporary memory is operated by the service provider, user convenience can be increased analogously to the statement made above, since the service provider takes over the administration of the access information.
- the execution of transactions provides for the signing of smart contracts.
- Some cryptocurrencies such as Ethereum support the use of smart contracts.
- the transactions can be supplemented with withdrawal conditions. If the payout conditions are met, for example leaving the country in which the cryptocurrency is considered illegal, an automatic refund to the vehicle is initiated.
- temporal specifications such as a specific date and/or a specific time can also be stored.
- a further advantageous embodiment of the method also provides that the transaction is linked to the service provider's escrow account with a vehicle identifier and/or a message sent to the service provider to transmit the copy of the access information is encrypted with a public key of the vehicle.
- the public key of the vehicle is a cryptographic key that differs from the public key of the hardware wallet and can be used in the vehicle for various cryptographic processes.
- the corresponding private key of the vehicle which is only known to the vehicle itself, is then required for renewed access to the copy of the access information.
- the linking with the vehicle identifier or encryption with a public key of the vehicle enables transactions to be assigned to vehicles or the corresponding hardware wallets to which the vehicle's processing unit has access. This facilitates the automated return transfer of the cryptocurrency units.
- Using the vehicle's public key has very special advantages.
- the encrypted access information can only be decrypted in the vehicle itself, which makes it difficult or impossible for an attacker to access the cryptocurrency units assigned to the crypto account, even if the attacker should come into possession of the access information encrypted using the public key of the vehicle .
- a central processing unit operated by a service provider determines a recommendation for transaction fees depending on the time required by the vehicle to enter the country in which possession of at least one cryptocurrency is considered illegal, the amount of the transaction fees is chosen so high that the transaction can be completed before the vehicle enters the country.
- the miners calculate the currently queued commissioned transactions. Only after the miners have confirmed the transaction will it be executed. The more transactions that have been commissioned, the longer it will take for them to be executed. This can result in a lack of time for the person driving the vehicle, since the person driving the vehicle has to enter the vehicle when there is a high volume of transactions of the country where the cryptocurrency is banned before the transaction required to transfer to the third-party account has been completed.
- the central processing unit of the service provider determines, depending on the estimated travel time of the vehicle until entering the relevant country, the lowest transaction fee that must be paid at least so that the transaction for transferring the units of the cryptocurrency to the third-party account is completed before the vehicle leaves the country where cryptocurrency is banned.
- the amount of the transaction fee can be selected so high that a certain time buffer is maintained so that the transaction will be completed earlier if the vehicle should arrive at the national border faster. Such a buffer can be, for example, 10 minutes, 20 minutes or fractions or multiples thereof.
- the service provider's central processing unit is, for example, a cloud server, also known as the backend.
- the trustee account can also be present on the cloud server or the memory can be provided for temporarily storing the copy of the access information.
- the service provider's central processing unit and/or the vehicle's processing unit monitor the commissioned transaction so that the person driving the vehicle can be informed when the transaction has been confirmed. For example, push messages can be sent to the person driving the vehicle every x minutes. This informs the driver of the vehicle whether the units of the prohibited cryptocurrency have been transferred to the third-party account, so that the person driving the vehicle can safely cross the national border.
- the units of the crypto currency remain assigned to the crypto account and instead the access information is removed from the hardware wallet, this results in some advantages for the person to whom the crypto account is assigned. On the one hand, they do not have to pay any transaction fees. On the other hand, there is no risk that the transaction will be carried out too late, i.e. only after crossing the national border. Furthermore, there is a risk that during the stay of the person, i.e. the vehicle, in the country where the cryptocurrency is considered illegal, an actor transfers units of the cryptocurrency considered illegal in the country to the corresponding crypto account. By doing so, the person to whom the crypto account is assigned would be violating the relevant law of the country. This can only be avoided if the access information stored in the hardware wallet is deleted from it. This also has the advantage that the units of the cryptocurrency cannot be confiscated by third parties, for example state authorities, since it is technically not possible to carry out transactions without the access information being available.
- deleting the access information from the hardware wallet has a major disadvantage. If the access information is removed from the hardware wallet, there is a general risk that the access information will be lost due to a human or technical error, for example because the person who owns the crypto account does not have a copy of the access information in a safe place and no recovery Seed has to restore the access information, or the access information is stolen by third parties, for example when transferring the copy of the access information from the vehicle.
- the person to whom the crypto account is assigned must therefore consider for themselves which solution they would like to take, i.e. whether the units of the crypto currency should preferably be transferred to the third-party account or whether the access information should be temporarily removed from the hardware wallet. In general, of course, both measures could also be carried out simultaneously.
- a further advantageous embodiment of the method according to the invention also provides that when entering a country in which possession of the at least one crypto currency is permitted, the units of the crypto currency previously removed from the crypto account are transferred back to the crypto account by carrying out a corresponding transaction and/or or, depending on the chosen procedure, the copies of the access information deleted from the hardware wallet are transferred back to the hardware wallet.
- the vehicle owner or corresponding vehicle occupants when leaving the country in which the possession of the cryptocurrency is prohibited and entering a country in which the possession of the corresponding cryptocurrency is allowed, the corresponding units of the cryptocurrency are transferred back to the crypto account or the access information is integrated back into the hardware wallet.
- This action can take place automatically or information can be output to the person driving the vehicle as to whether the reverse transformation of the units of the cryptocurrency to the cryptocurrency account should be initiated. If the person confirms this, the corresponding transaction or retransmission of the access information is initiated.
- the restriction that transactions can only be initiated automatically depending on the whereabouts of the vehicle has the advantage that the person to whom the crypto account is assigned cannot be forced to use the units of the crypto currency while staying in the country in which the at least a cryptocurrency is forbidden to transfer.
- the steps carried out to remove and/or transfer back the units of cryptocurrencies and/or the access information are carried out by the Computing unit automatically carried out or initiated again.
- the comfort for the person driving the vehicle can be increased even further.
- the person driving the vehicle is a businessman who commutes across national borders several times a week for professional reasons, with possession of the cryptocurrency being permitted in a first country and possession of the cryptocurrency being prohibited in the second country, the of the laws to grant or restrict access to the corresponding cryptocurrency for each commute.
- the person driving the vehicle can then specify how the corresponding restriction should take place. This procedure can be saved and carried out automatically by the vehicle, i.e. the computing unit, using the same method when recognizing the repeated change of country.
- the processing unit can conclude from this that this is a standard case that is carried out particularly frequently and therefore the same procedure for granting or revoking access permission to the cryptocurrency should take place. For example, if an input request is to be issued to the person driving the vehicle each time before a transaction is carried out or the access information is copied, this can be done automatically for each trip. However, it is also possible for the input request to be issued only on the first trip and for the transaction to then be automatically initiated by the processing unit on each subsequent trip, without the need for the person driving the vehicle to first have to confirm the initiation of the transaction. If the journey with the vehicle leads through several countries and a country in which the possession of at least one cryptocurrency is permitted is only passed comparatively briefly, the units of the cryptocurrency can also be transferred back to the crypto account or the access information to the hardware Wallet to be waived.
- a further advantageous embodiment of the method according to the invention also provides that the computing unit automatically issues a warning to a person driving the vehicle if it detects that the vehicle is approaching a country in which the possession of cryptocurrencies that can be used from the vehicle is prohibited is.
- the processing unit can initiate the transfer of the units of the cryptocurrency and/or the transmission of the access information from the hardware wallet in an automated manner or only after a person driving the vehicle or vehicle occupant has confirmed this. For this purpose, the person concerned is warned before entering the country.
- An approach to the corresponding country can be recognized in different ways. For example, a programmed navigation route can be evaluated.
- the navigation route can be programmed into a navigation system of the vehicle, for example, or also into a mobile terminal such as a smartphone or a mobile navigation device, which communicates with the computing unit of the vehicle. If no navigation route has been programmed, a geo-position of the vehicle can also be monitored. If the vehicle approaches a national border of a country in which the possession of at least one cryptocurrency is prohibited within a specified distance, the warning is issued or automatically caused by the processing unit that the corresponding transaction is transferred to the third-party account and/or the Transferring the copy of the access information and deleting it from the hardware wallet is carried out.
- the processing unit preferably retrieves or receives information from a central processing unit in order to update the country-specific legal provisions on the ownership of cryptocurrencies stored in the processing unit.
- the computing unit can also call up or receive information for countries that the vehicle is not currently in the vicinity of. This is useful for the driver who owns banned cryptocurrencies in the relevant distant country and plans to visit that country soon.
- the person driving the vehicle can also specify which cryptocurrencies can be used from the vehicle. If the processing unit itself is not able to determine this, the processing unit can still be informed by manual input as to which cryptocurrencies can be used from the vehicle.
- the processing unit can call up or receive the information from the central processing unit regularly or irregularly.
- the legal provisions can be updated according to fixed time intervals.
- a time interval can be 10 minutes, 30 minutes, 6 hours or multiples or fractions thereof.
- the legal provisions can also be updated after driving a specific route with the vehicle, for example every 100 km, 1000 km or even fractions or multiples thereof, as well as when staying at a specific location.
- the specific location can be, for example, a place of residence of the vehicle owner, his place of work or also a national border.
- updating the legal Provisions are event-based. Such an event is, for example, starting the vehicle or carrying out a maintenance interval in a workshop.
- the computing unit and the wireless communication device are set up to carry out a method described above.
- the vehicle is any vehicle such as a car, truck, van, bus or the like.
- the computing unit is permanently integrated into the vehicle and can be formed, for example, from a telematics unit, a central on-board computer, a control unit of a vehicle subsystem or the like.
- the processing unit is able to exchange information with other devices wirelessly and, if necessary, also via cables.
- the processing unit can receive information for updating the country-specific legal provisions via mobile radio, and can arrange for the transactions of the units of the cryptocurrency to be carried out and/or the transmission of the access information to be carried out.
- Communication with vehicle-external hardware wallets is also possible.
- the hardware wallet can also be integrated into the vehicle. The hardware wallet can thus be integrated into the computing unit itself.
- FIG. 1 shows a schematic representation of a vehicle according to the invention in a plan view
- FIG. 2 shows a schematic section from a map showing a vehicle that is in a country in which possession of a specific cryptocurrency is permitted
- FIG. and 3 shows a schematic detail from a map showing a vehicle that is on a route through several countries.
- FIG. 1 shows a vehicle 1 according to the invention, here in the form of a car.
- the vehicle 1 includes a computing unit 3 which is in communication with a wireless communication device 7 .
- the computing unit 3 can use the wireless communication device 7 to exchange information with other devices such as a mobile radio base station 8 which can be linked to the Internet 9 .
- the processing unit 3 has access to at least one hardware wallet 2, in which access information for a crypto account of the person driving the vehicle is kept.
- the hardware wallet 2 can be integrated, for example, in the computing unit 3 itself, or also in a USB stick (not shown) or a mobile terminal device 10, such as a smartphone.
- the mobile terminal 10 can also exchange data with the processing unit 3 via the wireless communication device 7 .
- the processing unit 3 can also set up a communication connection to the Internet via tethering via the mobile terminal device 10 .
- the wireless communication device 7 can be a telematics unit, for example.
- the vehicle 1 includes a man-machine interface 11, for example in the form of a touch display.
- the computing unit 3 can output information to the person driving the vehicle via the man-machine interface 11 and, on the other hand, the person driving the vehicle can enter operator control actions in order to issue commands to the computing unit 3 .
- the hardware wallet 2 allows access information to be carried, typically in the form of a private key for a crypto account.
- the crypto account can have a crypto account identifier, typically in the form of a public key, via which the crypto account can be addressed.
- Units of at least one cryptocurrency can thus be assigned to the crypto account.
- the access information is typically stored in the hardware wallet 2 in cryptographically encrypted form. It can now be the case that the crypto account whose access information is carried in the hardware wallet 2 is prohibited in a specific country.
- the computing unit 3 initiates a transfer of the units of the at least one crypto currency prohibited in the specific country B (see Figure 2) to a if there is a risk of violation Third-party account and/or the transfer of the access information to a vehicle-external temporary memory 4.
- the temporary memory 4 itself can be a persistent memory, in which context "temporary" means that the access information is back in the hardware wallet after a certain time has elapsed 2 of the vehicle is transferred, so that the copy of the access information can be safely deleted from the temporary memory 4.
- the third party account and/or the temporary storage 4 can be managed by a service provider.
- FIG. 2 shows a schematic representation of a map.
- the vehicle 1 is in a country A in which cryptocurrencies that can be used in the vehicle 1 are owned is allowed, at a location 12.
- the vehicle 1 is in a vicinity of a country B where possession of the corresponding cryptocurrency or cryptocurrencies usable from the vehicle 1 is prohibited. If vehicle 1 enters country B, there is a risk of a violation of the law.
- the computing unit 3 therefore checks whether entering country B is imminent. For this purpose, the processing unit 3 checks, for example, whether the vehicle 1 is on a route 6 to the country B, or whether a national border to the country B is located within a radius around the vehicle 1 described by a radius r.
- the vehicle 1 issues a warning to the person driving the vehicle that a violation of the law is imminent and that an action must be taken.
- Either the corresponding units of the cryptocurrencies are to be transferred to the third-party account and/or the access information is to be removed from the hardware wallet 2.
- the processing unit 3 can also initiate the corresponding action automatically, so that it is not necessary to enter a manual operator action.
- the computing unit 3 can then output corresponding information to the person driving the vehicle that the corresponding action was carried out automatically.
- FIG. 3 shows a journey of the vehicle 1 on a route 6 through several countries A, B, C. Possession of a corresponding cryptocurrency is permitted in countries A and C and prohibited in country B.
- An exemplary method sequence could appear as follows: First, the computing unit 3 issues a corresponding warning to the person driving the vehicle via the human-machine interface 11 that a possible violation of the law is imminent. The person driving the vehicle then decides to outsource the access information, ie the private key of the hardware wallet 2, to the vehicle-external temporary memory 4. The processing unit 3 then generates an encrypted message that contains the access information and sends it to a cloud server of the service provider via the wireless communication interface 7 .
- this message can be encrypted with the public key of vehicle 1, so that this message can only be decrypted again in this vehicle 1.
- the corresponding message is received by the service provider's central processing unit 5 and stored in encrypted form in an encrypted memory, ie the temporary memory 4 external to the vehicle. If necessary, the successful transmission can be acknowledged to the vehicle 1 become.
- the access information is then deleted from the processing unit 3 or the hardware wallet 2 to which the processing unit 3 has access. This only affects the hardware wallets 2 with the corresponding access information, whose cryptocurrencies are banned in country B.
- the vehicle 1 can therefore also generally have access to more than one hardware wallet 2 . However, access to the cryptocurrencies not affected by the ban and the corresponding hardware wallets 2 is not restricted. Now the vehicle 1 can enter the country B without violating the law.
- the person driving the vehicle After leaving country B, the person driving the vehicle triggers the retransmission of the access information.
- the corresponding access information or a plurality of access information it may be necessary for the person driving the vehicle to authenticate himself. Any method can be used for this, such as biometric authentication, authentication using a user name and password, scanning an optoelectronic code or the like.
- the computing unit 3 can also initiate the retransmission of the access information itself as a function of an automatically detected vehicle position.
- the service provider then checks the corresponding request and, after successful authentication, transmits the access information to the computing unit 3. The copies of the access information are then deleted from the temporary memory 4.
- FIG. 3 shows four vehicle positions P1, P2, P3, P4.
- the computing unit 3 issues the warning message to the person driving the vehicle for the first vehicle position P1.
- vehicle 1 the person driving the vehicle is offered solution variants, i.e. the question is asked whether the units of the cryptocurrency should be transferred to the third-party account and, if so, whether a personal third-party account should be used or a trust account managed by the service provider, and whether so-called smart Contracts are to be used.
- the access information can also be extracted from the hardware wallet 2 .
- the arithmetic unit 3 or the central arithmetic unit 5 after the choice of a solution variant by the person driving the vehicle, estimates transaction costs that are so high that when the units of the cryptocurrency to the third-party account, the transaction is completed before vehicle 1 crosses the border to country B. This is an estimate because it can only give a probability of how reliable the execution of the transaction is. For example, such high transaction costs can be selected that the transaction will be completed with a 90% or 95% probability when vehicle 1 enters country B.
- the arithmetic unit 3 After the arithmetic unit 3 has received a confirmation from the person driving the vehicle via the man-machine interface 11, the corresponding transaction is initiated.
- the transaction was successfully executed at the third vehicle position P3.
- the hardware wallet 2, to which the processing unit 3 has access, then no longer holds any stocks of the cryptocurrency.
- the units of the cryptocurrency extracted from the vehicle 1 are transferred back, possibly automatically, back to the crypto account from which transactions are possible if the access information stored in the hardware wallet 2 is present.
