Detailed Description
In order to make the technical solutions in the present specification better understood, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the accompanying drawings in one or more embodiments of the present specification, and it is obvious that the one or more embodiments described are only a part of the embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.
Example one
Referring to fig. 1, a schematic step diagram of a block chain transaction uplink method provided in an embodiment of the present disclosure is shown, it should be understood that the method is applied in a block chain service system using radio frequency identification RFID, that is, an RFID technology is combined with a block chain technology to implement uplink processing for block chain transactions. Referring to the architecture diagram of the blockchain business system shown in fig. 2, the executing entity participating in the blockchain uplink transaction scheme may include: an electronic tag 202, a read-write device 204 and a blockchain service node 206; the electronic tags 202 are composed of coupling elements and chips, each electronic tag 202 has a unique electronic code, and a high-capacity electronic tag has a user writable storage space; it should be understood that the electronic tag 202 may be attached to an object to identify a target object, where the object may be a target operation object related to a blockchain service, and is described in detail later through a specific service scenario, which is not limited herein. The read-write device 204 is a device for reading or writing tag information, and the read-write device 204 can be used by being attached to a terminal device. It should be noted that, inside the electronic tag 202 and the read/write device 204, antennas for receiving and/or transmitting signals are uniformly arranged, but not shown in fig. 2. The blockchain service node 206 may be any node device in the blockchain network that exists as an access point for transactions in the blockchain network.
Still referring to fig. 1, the block chain uplink transaction method may include the following steps:
step 102: the read-write device carries out identity recognition on the electronic tag which is close to and can trigger the transaction initiation.
The chip is arranged in the electronic tag, and the chip stores a target object identifier which is associated with the electronic tag and used for triggering related transactions of the block chain service, wherein the target object identifier can be a name or a code of a target object and can identify the uniqueness of the target object. In fact, in general, the target object may be a carrier of an electronic tag, that is, the electronic tag is attached to the target object to "give" the target object a function of the electronic tag. Meanwhile, a private key generated by a user based on a target object and a signature algorithm for performing signature operation on the received corresponding transaction by using the private key are also stored in the chip. It should be understood that all the electronic tags may use the same signature algorithm for the same RFID system; signature algorithms used by different RFID systems may or may not be distinguished, and are not limited herein.
Antennas are further arranged in the reading and writing device and the electronic tag, and when the electronic tag is close to the reading and writing device, the reading and writing device and the electronic tag are in wireless connection in a wireless radio frequency mode. And after the non-contact bidirectional data communication link is established, reading and writing the electronic tag by using a wireless radio frequency mode.
In this embodiment of the present description, the reading and writing device reads and writes the electronic tag, and first obtains the identity of the electronic tag or the identity of a target object represented by the electronic tag. Here, the identity information may be a target object identification. That is, the read-write device reads the identity information in the electronic tag, so as to identify the identity of the target object capable of initiating the transaction.
In an implementation manner, when the read-write apparatus performs identity recognition on an electronic tag that triggers a transaction initiation, the implementation is specifically as follows: and the read-write device reads the identification information which is stored in the electronic tag and can represent the unique identity of the electronic tag through an RFID technology. Therefore, a transaction related to the block chain service can be accurately constructed and initiated based on the identified identity.
Step 104: and after the transaction related to the service is constructed based on the identified identity information, the read-write device sends the constructed transaction to the electronic tag.
In embodiments of the present description, the manner of constructing the transaction may include:
the first method is as follows: the read-write device constructs the transaction related to the current service based on the identified identity information and the current service application type; in other words, the transaction construction process is mainly completed by the read-write device, that is, after the read-write device recognizes the identity information, the transaction is constructed based on the identity information and the current service application type. For example, the reader-writer constructs the transaction "Zhang Sandi Tianjin Dongdong station 13 o 03 registers identity card at the entrance of the station"
The second method comprises the following steps: and the read-write device cooperates with the electronic tag to construct a transaction related to the current service based on the identified identity information and the current service application type. That is, the transaction construction process is performed by the read/write device and the electronic tag, and the calculation and storage functions of the electronic tag are weaker than those of the read/write device, so that the transaction construction process is performed by the read/write device in most cases.
Step 106: and the electronic tag signs the transaction and sends the transaction to the read-write device.
In an implementation manner, a private key and a signature algorithm corresponding to the electronic tag are stored in a chip of the electronic tag; then, the signing of the transaction by the electronic tag may be implemented as:
the electronic tag signs the transaction by using the locally stored signature algorithm based on a corresponding private key.
Considering the wireless radio frequency link communication established between the electronic tag and the read-write device through the RFID, the read-write device can send the constructed transaction to the electronic tag through the wireless radio frequency link, and the electronic tag which is not connected with the network signs the transaction. Therefore, the read-write device is directly connected with the network, and the electronic tag for signature is communicated with the read-write device only through the wireless radio frequency link established by the RFID, so that the leakage of the private key for signature stored in the electronic tag is effectively isolated, and the security risk brought by the fact that the read-write device intensively hosts the private key is avoided.
It should be understood that the specific implementation of the signature operation described in this embodiment of this specification may be performed in the existing manner, and is not described herein again.
Step 108: and the read-write device uploads the signed transaction to a block chain service node for transaction chain linking processing.
Optionally, in this embodiment of the present specification, the block chain service using radio frequency identification RFID at least includes:
identity recognition service, anti-counterfeiting verification service, asset management service, information management service, and security control service. Some of the services are detailed later by specific examples.
Through the technical scheme, a new block chain transaction uplink mode is provided, and in the scheme, the reading and writing device identifies the identity of the electronic tag; after the transaction related to the service is constructed based on the identified identity information, the read-write device sends the constructed transaction to the electronic tag for signature; and returning to the read-write device for transaction uploading after the signature is completed. Because the electronic tag is not connected with the network, when the electronic tag is used as a transaction sending terminal and indirectly sends the signed transaction to a block chain scene, the private key stored in the electronic tag is relatively safe, so that the block chain transaction chaining submitted by RFID equipment is realized in various application scenes in which the RFID and the block chain are combined, and meanwhile, the risk of intensively hosting the private key is avoided.
The following describes a specific application scenario related to the uplink block chain transaction scheme based on the above-mentioned block chain service.
1. Logistics service
Logistics warehousing is one of the most potential application fields of RFID, and UPS, DHL, Fedex and other international logistics are actively experimenting RFID technologies, so that the logistics technology can be applied to the improvement of logistics capacity in the future on a large scale. Specific services that can use the uplink block chain transaction scheme of the present application may include: cargo tracking, automatic information acquisition, warehousing management application, port application, postal packages, express delivery and the like in the logistics process. Under the service scenes, the block chain transaction uplink scheme can be adopted to process the logistics information so as to realize effective management and allocation of goods.
2. Traffic control system
Specific services that can use the uplink block chain transaction scheme of the present application include: taxi management, bus hub management, railway locomotive identification and the like, so as to carry out cochain storage on traffic management information.
3. Identity recognition
Specific services that can use the uplink block chain transaction scheme of the present application include: electronic passport items, second generation identity cards, student cards, and other various electronic documents.
4. Anti-counterfeiting method
Specific services that can use the uplink block chain transaction scheme of the present application include: the anti-counterfeiting of valuables (cigarettes, wine and medicines), tickets, and the like.
5. Asset management
Specific services that can use the uplink block chain transaction scheme of the present application include: valuables, large numbers of items with high similarity, or dangerous items, etc.
6. Food product
Specific services that can use the uplink block chain transaction scheme of the present application include: fruits, vegetables, fresh foods, medicines and the like. For example, tracing is implemented.
7. Information statistics
The inquiry software of the file informatization management platform transmits a statistical clearing signal, and the reader quickly reads the data information and the related storage information of the collected files and intelligently returns the acquired information and the information in the central information base for proofreading. If the files which cannot be matched are targeted, the manager uses the reader to perform field verification, and adjusts the system information and the field information, thereby completing the information statistics work.
8. Look-up application
When inquiring the file information, the file manager finds out the file number by the inquiry management platform, the system reads the data information in the central information base according to the file number, after checking, the file is transmitted out of the base, the intelligent file identification function module of the storage position management platform can find out the specific part stored by the file by combining the file number with the corresponding storage position number. After the manager sends out the file delivery signal, the indicator lamp on the storage site is immediately lighted. When the data is delivered out of the warehouse, the radio frequency identification reader feeds back the acquired information to the management platform, the manager checks again, and the delivered archive and the checked archive are checked to be the same and then delivered out of the warehouse. Moreover, the system will record the time of the information going out of the warehouse. If the feedback file is not matched with the query file, an alarm module in the safety management platform transmits abnormal early warning.
9. Safety control
The security control system can realize functions of timely monitoring and abnormal alarming of the archives so as to prevent the archives from being damaged and stolen. When the files are borrowed and returned, particularly the physical files are often used for exhibition, evaluation and inspection and the like, managers carefully inspect the returned files and verify the returned files with the information before the files are borrowed, and whether the files are damaged or lost or not can be timely found.
Next, taking identification as an example, the process of using the uplink block chain transaction scheme of the present application is briefly described. Specifically, a signature algorithm module and a private key storage module can be arranged in an 'identity card' chip serving as an electronic tag, or the signature algorithm and the private key can be directly written into the chip to enable the chip to become an independent block chain account. When the ID card is close to the certificate reader-writer, a transaction data can be constructed, the ID card completes the transaction signature, the signature is sent to the certificate reader-writer, and the signature is submitted to the block chain by the certificate reader-writer, so that the chain chaining processing of one transaction is completed. In the whole process, a main body (identity card) sending the transaction does not need to be connected with a network, so that a private key stored in the identity card is safe, a certificate reader-writer is not required to be centrally managed, the risk of leakage is effectively reduced, and meanwhile, the block chain transaction uplink submitted by RFID equipment is realized in various application scenes of combining the RFID and the block chain.
Example two
Another uplink block chain transaction method is further provided in an embodiment of the present specification, and as shown in fig. 3, the method includes:
step 302: the method comprises the following steps that a first terminal carries out identity recognition on a second terminal which is close to and can trigger transaction initiation, wherein the first terminal and the second terminal carry out message transmission through a communication link established by an RFID technology.
Step 304: after constructing a transaction related to the current service based on the identified identity information, the first terminal transmits the constructed transaction to the second terminal.
Step 306: and the second terminal signs the transaction and sends the signature to the first terminal.
Optionally, a private key and a signature algorithm corresponding to the second terminal are saved in a chip of the second terminal; the signing of the transaction by the second terminal specifically comprises:
and the second terminal signs the transaction by using the locally stored signature algorithm based on a corresponding private key.
Step 308: and the first terminal uploads the signed transaction to a block chain server for transaction uplink processing.
Optionally, the service using radio frequency identification RFID at least includes: identity recognition service, anti-counterfeiting verification service, asset management service, information management service, and security control service.
It should be understood that, in the second embodiment, the first terminal may be a terminal device having all functions of the electronic tag described in the first embodiment. The second terminal may be a terminal device having all the functions of the read/write apparatus described in the first embodiment. The first terminal and the second terminal can carry out RFID communication, the first terminal is not connected with a network, and the second terminal can directly connect with the network to upload data. Therefore, the first terminal can safely conduct transaction signature, the private key does not need to be leaked, and the security risk caused by the fact that the second terminal centrally trusts the private key is avoided.
