Background
The Blockchain (Blockchain) mainly solves the trust and security problems of the transaction. As broadly understood, the blockchain technology is to utilize a blockchain data structure to verify and store data, utilize a distributed node consensus algorithm to generate and update data, and utilize a cryptographic manner to secure data transmission and access. In order to ensure the security of the user applying the blockchain during the transaction, a private key is usually configured for the user terminal, and the private key configured for the user signs the transaction process of the user applying the blockchain system. If the private key is lost and the user is difficult to trade, the improvement of the security of the private key of the user becomes a problem to be solved urgently.
The private key is a key created by a user who performs a transaction and used only by the private key, and the security of the private key is mainly considered from the aspects of storage, creation and use of the private key. The general private key creation method is that a user inputs a password through an application client, and then the password input by the user is encrypted through an encryption chip to generate a private key. If the user forgets the password or the password of the user is stolen, the private key corresponding to the password can be easily cracked according to the encryption algorithm.

The hardware wallet does not comprise various communication modules, the hardware wallet does not comprise various communication modules such as a WIFI module, a Bluetooth module and a mobile communication module, and the hardware wallet does not comprise the communication module and a communication interface, namely the hardware wallet does not comprise the communication module and does not comprise the communication interface. The networking terminal comprises a controller, a display, a camera, a memory, a wifi module and a processor, wherein the processor comprises a two-dimensional code generation module, a two-dimensional code scanning module, a data encryption and decryption module and a transaction module.
In the embodiment, when a networking terminal receives a transaction request, transaction information corresponding to the transaction request is obtained, the networking terminal generates and displays a first two-dimensional code based on the transaction information, specifically, a user fills transaction information such as a payee address, a transfer amount, a mine cost and remark information in an App of the networking terminal, and triggers the transaction request through a display interface sending button, when the networking terminal receives the transaction request, the networking terminal calls a transaction module to obtain the transaction information corresponding to the transaction request, the networking terminal converts the transaction information into the first two-dimensional code through a two-dimensional code generation module, and the first two-dimensional code is displayed on a display screen of the networking terminal.

Step S102, the hardware wallet carries out transaction signature operation based on the transaction information to obtain signature information, and encrypts the signature information based on a preset public key to obtain encrypted signature information;
in this embodiment, when the transaction information is obtained, the hardware wallet performs a transaction signature operation based on the transaction information to obtain signature information, that is, the hardware wallet performs a transaction signature on the transaction information through a transaction module thereof to obtain signature information. When the signature information is obtained, the hardware wallet encrypts the signature information based on a preset public key to obtain the encrypted signature information, wherein the preset public key is a preset private key and uniquely corresponds to the networking terminal.
Step S103, if the data length corresponding to the encrypted signature information is greater than a preset data length, the hardware wallet splits the encrypted signature information based on the preset data length to obtain a plurality of sub-signature information;
in this embodiment, in order to improve the recognition rate of the two-dimensional code, the content length of the two-dimensional code needs to be reduced, and then when the decrypted signature information is obtained, the hardware wallet obtains the data length corresponding to the encrypted signature information, and determines whether the data length is greater than a preset data length.
If the data length is greater than the preset data length, the hardware wallet splits the encrypted signature information based on the preset data length to obtain a plurality of sub-signature information and also can obtain a splitting sequence, wherein the splitting sequence is the sequence of each sub-signature information in the encrypted signature information, specifically, the data lengths of all sub-signature information except the last sub-signature information in each signature information are the preset data length, and the data length of the last sub-signature information is less than or equal to the preset data length.
And step S104, the hardware wallet generates second two-dimensional codes corresponding to the sub-signature information and displays the second two-dimensional codes in sequence, wherein the networking terminal acquires the two-dimensional code information corresponding to the second two-dimensional code currently displayed by the hardware wallet through a second camera, decrypts the two-dimensional code information based on a preset public key to obtain the signature information, and uploads the signature information to a block chain.
In this embodiment, when the sub-signature information is acquired, the hardware wallet generates the second two-dimensional codes based on the sub-signature information, and sequentially displays the second two-dimensional codes on a display screen of the hardware wallet. The networking terminal acquires the two-dimensional code information corresponding to the second two-dimensional code currently displayed by the hardware wallet through the second camera, specifically, a user can trigger a two-dimensional code scanning request through keys and the like of the networking terminal, and simultaneously, the second camera of the networking terminal is aligned to the display screen of the hardware wallet, and the networking terminal scans the second two-dimensional code currently displayed by the hardware wallet through the second camera to obtain the two-dimensional code information corresponding to the second two-dimensional code.
After the two-dimension code information is obtained, the networking terminal carries out decryption operation on the two-dimension code information based on a preset public key so as to obtain the signature information, wherein the preset public key uniquely corresponds to the preset public key, and finally the networking terminal uploads the signature information to a block chain.
Further, in an embodiment, the step S104 includes:
the hardware wallet generates second two-dimensional codes corresponding to the sub-signature information, the second two-dimensional codes are sequentially displayed based on the signature sequence of the sub-signature information, the networking terminal acquires the two-dimensional code information corresponding to the second two-dimensional code currently displayed by the hardware wallet through the second camera, and when the two-dimensional code information is determined to be complete, the two-dimensional code information is decrypted based on a preset public key to obtain the signature information, and the signature information is uploaded to the block chain.
In this embodiment, the hardware wallet sequentially displays the second two-dimensional codes based on the signature sequence of the sub-signature information. When the networking terminal acquires the two-dimension code information corresponding to the second two-dimension code currently displayed by the hardware wallet through the second camera, whether the two-dimension code information is complete or not is firstly determined, namely whether the two-dimension code information of all the second two-dimension codes is currently received or not is determined, and when the two-dimension code information is determined to be complete, the two-dimension code information is decrypted based on a preset public key so as to obtain the signature information, and the signature information is uploaded to the block chain.
Specifically, when the second two-dimensional codes are generated, the second two-dimensional codes are generated based on the number of the sub-signature information and the sub-signature information, namely the content of each second two-dimensional code carries the total number of the sub-signature information (or the second two-dimensional codes), when the two-dimensional code information is received, whether the number of the two-dimensional code information corresponding to the second two-dimensional code is the same as the total number is determined, namely whether the number of the two-dimensional codes scanned by the second camera through the current networking terminal is the same as the total number is determined, if yes, the two-dimensional code information is determined to be complete, integrity of transaction information is ensured through integrity verification, and further the efficiency of block chain transaction is improved.
It should be noted that the hardware wallet may perform timing display when sequentially displaying each second two-dimensional code, that is, displaying one second two-dimensional code at preset intervals.
In the transaction method based on the hardware wallet, transaction information corresponding to a first two-dimensional code currently displayed by a networked terminal is acquired through the hardware wallet through a first camera, wherein the networked terminal acquires the transaction information corresponding to a transaction request when receiving the transaction request, and generates and displays the first two-dimensional code based on the transaction information; then the hardware wallet carries out transaction signature operation based on the transaction information to obtain signature information, and encrypts the signature information based on a preset public key to obtain encrypted signature information; then, if the data length corresponding to the encrypted signature information is greater than the preset data length, the hardware wallet splits the encrypted signature information based on the preset data length to obtain a plurality of sub-signature information; and then the hardware wallet generates second two-dimensional codes corresponding to the sub-signature information and displays the second two-dimensional codes in sequence, wherein the networking terminal acquires the two-dimensional code information corresponding to the second two-dimensional code currently displayed by the hardware wallet through a second camera, decrypts the two-dimensional code information based on a preset public key to obtain the signature information, uploads the signature information to the block chain, and the transaction is carried out through the preset public key in the hardware wallet, so that the preset public key cannot be out of the hardware wallet, the preset public key can be prevented from being stolen, and the security of a private key in the block chain system is improved. By splitting the signature information, the identification efficiency of the two-dimensional code is improved by reducing the data volume of single transmission.

In this embodiment, in the process that the networking terminal acquires the second two-dimensional code currently displayed by the hardware wallet through the second camera, there may be a situation that the second two-dimensional code currently displayed is not acquired due to movement of the networking terminal or the like, at this time, playback of the two-dimensional code may be performed by touching the display screen of the hardware wallet, that is, the display screen of the hardware wallet is a touch screen, and a sliding touch operation of the playback of the two-dimensional code may be triggered by touching the touch screen.
When a first sliding touch operation triggered by the display screen of the hardware wallet is detected, for example, the first sliding touch operation may be a leftward sliding operation, the hardware wallet determines a first two-dimensional code to be displayed before a second two-dimensional code to be displayed currently based on the signature sequence, and the hardware wallet displays the first two-dimensional code to be displayed, so that playback of the two-dimensional codes is realized, integrity of signature information is improved, and efficiency of block chain transaction is further improved.
