Authorizing multiparty blockchain transactions via one-time passwords
View Patent ↗An example operation may include one or more of creating a proposed transaction including one or more assets, transmitting the proposed transaction to a user device for authorization, receiving authorization from the user device via an asynchronous one-time password to authorize the proposed transaction, and creating a blockchain transaction including the asynchronous one-time password and content of the proposed transaction responsive to receiving the authorization.
1. A method, comprising:
creating, via an Internet of Things (IoT) device, a proposed transaction comprising identifiers of one or more assets;
receiving, via the IoT device, a wireless transfer of a one-time password by near-field communication from a hardware token disposed within a predetermined physical proximity to the IoT device, the one-time password being verifiable based on a public key of a user;
generating, via the IoT device, a blockchain transaction comprising the one-time password that is verifiable based on the public key of the user, a public key of the IoT device, the public key of the authorized user, and content of the proposed transaction, responsive to receiving the wireless transfer;
signing the blockchain transaction with a private key of the IoT device; and
transmitting the signed blockchain transaction to a blockchain network.
2. The method of claim 1 , further comprising:
hashing the public key of the user, the public key of the IoT device, and the content of the proposed transaction, and storing a verifiable hash identifier of the hash in the blockchain transaction.
3. The method of claim 1 , wherein the blockchain transaction comprises a list of the one or more assets generated by the IoT device.
4. The method of claim 1 , wherein the receiving comprises receiving the one-time password via one or more of a near field communication (NFC) message, a radio frequency identification (RFID) message, and a Bluetooth message, transmitted by the hardware token being brought within the predetermined physical proximity of the IoT device.
5. The method of claim 1 , wherein the blockchain transaction further comprises a timestamp, a hash ID, an origin address, and a destination address.
6. A system, comprising:
a processor configured to
create, via an Internet of Things (IoT) device, a proposed transaction comprising identifiers of one or more assets;
receive, via the IoT device, a wireless transfer of a one-time password by near-field communication from a hardware token disposed within a predetermined physical proximity to the IoT device, the one-time password being verifiable based on a public key of a user;
generate, via the IoT device, a blockchain transaction comprising the one-time password that is verifiable based on the public key of the user, a public key of the IoT device, the public key of the authorized user, and content of the proposed transaction, responsive to the wireless transfer,
sign the blockchain transaction with a private key of the IoT device, and
transmit the signed blockchain transaction to a blockchain network.
7. The system of claim 6 , wherein the processor is further configured to hash the public key of the user, the public key of the IoT device, and the content of the proposed transaction, and store a verifiable hash identifier of the hash in the blockchain transaction.
8. The system of claim 6 , wherein the blockchain transaction comprises a list of the one or more assets generated by the IoT device.
9. The system of claim 6 , wherein the processor is configured to receive the one-time password via one or more of a near field communication (NFC) message, a radio frequency identification (RFID) message, and a Bluetooth message, transmitted by the hardware token being brought within the predetermined physical proximity of the IoT device.
10. The system of claim 6 , wherein the blockchain transaction further comprises a timestamp, a hash ID, an origin address, and a destination address.
11. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:
creating, via an Internet of Things (IoT) device, a proposed transaction comprising identifiers of one or more assets;
receiving, via the IoT device, a wireless transfer of a one-time password by near-field communication from a hardware token disposed within a predetermined physical proximity to the IoT device, the one-time password being verifiable based on a public key of a user;
generating, via the IoT device, a blockchain transaction comprising the one-time password that is verifiable based on the public key of the user, a public key of the IoT device, the public key of the user, and content of the proposed transaction, responsive to receiving the wireless transfer;
signing the blockchain transaction with a private key of the IoT device; and
transmitting the signed blockchain transaction to a blockchain network.
12. The non-transitory computer readable of claim 11 , wherein the processor is further configured to perform:
hashing the public key of the user, the public key of the IoT device, and the content of the proposed transaction, and storing a verifiable hash identifier of the hash in the blockchain transaction.
13. The non-transitory computer readable storage medium of claim 11 , wherein the blockchain transaction comprises a list of the one or more assets generated by the IoT device.
14. The non-transitory computer readable storage medium of claim 11 , wherein the receiving comprises receiving the one-time password via one or more of a near field communication (NFC) message, a radio frequency identification (RFID) message, and a Bluetooth message, transmitted by the hardware token being brought within the predetermined physical proximity of the IoT device.
