Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
FIG. 1 is a method flow diagram of a blockchain cold wallet based transaction method of the present invention. In step S1, a non-networking wallet server and a networking wallet server are configured, wherein a first scanning device and a first display device are additionally installed on the non-networking wallet server, and a second scanning device and a second display device are additionally installed on the networking wallet server. In a preferred embodiment of the invention, the non-networked wallet server may be any server that is unable to communicate with the external internet in any way. Therefore, the first scanning device and the first display device attached thereto can communicate only through the USB interface connector directly connected thereto. The first scanning device and the first display device are also not networked. The networked wallet server is responsible for local private key storage. Because it can't connect with external network, its local private key will not contact with network, so the security of private key can be ensured. The networked wallet server is connected with an external network through a blockchain. The second scanning device and the second display device which are additionally arranged on the device can communicate with each other through a USB interface connector which is directly connected with the device, and can also communicate with the device through the Internet. Preferably, the first scanning device and the second scanning device may be a code scanning gun, and the first display device and the second display device may be liquid crystal display screens. The first scanning device is arranged opposite to the second display device, and the second scanning device is arranged opposite to the first display device.
In step S2, the wallet server receives transaction data to be signed from the internet, encodes the two-dimensional code, encrypts the obtained two-dimensional code with a public key, and displays the encrypted two-dimensional code on the second display device. In a preferred embodiment of the present invention, the networked wallet server may employ any known encoding method to encode the obtained transaction data into a two-dimensional code that may be displayed by a display device. Further, any encryption method may be used to encrypt the obtained two-dimensional code. For example, a common DES and RSA hybrid encryption algorithm may be employed. Preferably, the encrypted two-dimensional code is updated and displayed at intervals of a set time, for example.
In step S3, the first scanning device scans and obtains the encrypted two-dimensional code, the non-networked wallet server decrypts the encrypted two-dimensional code by using a local private key to obtain the transaction data and signs by using the local private key, then two-dimensional code encoding is performed on the signed data to generate a signed two-dimensional code, and the first display device displays the signed two-dimensional code. Preferably, the first scanning device may scan and acquire the encrypted two-dimensional code in a timing polling manner. Of course, in another preferred embodiment of the present invention, the first scanning device may also keep the scanning device all the time, so as to acquire the two-dimensional code at the first time. In this step, the signature two-dimensional code may be encrypted again. In this step, the first scanning device can only obtain the encrypted two-dimensional code by means of two-dimensional code scanning, and transmit the encrypted two-dimensional code to the non-networking wallet server through the USB interface connector. After the non-networking wallet server generates the signature two-dimensional code, the first display device can only obtain the signature two-dimensional code through the USB interface connector. Thus guaranteeing the safety of the whole process.
In step S4, the second scanning device scans and acquires the signature two-dimensional code to obtain the signature data, and then the networked wallet server broadcasts the signature data through a blockchain. In this step, the second scanning device scans to obtain the signature two-dimensional code by means of timing polling. In another preferred embodiment of the present invention, the second scanning device may also keep the scanning device all the time, so as to acquire the two-dimensional code at the first time. In this step, the second scanning device can only obtain the signature two-dimensional code through a two-dimensional code scanning mode, but cannot communicate with the non-networking wallet server through other modes, so that the safety of the whole process is further ensured.
According to the transaction method based on the block chain cold wallet, disclosed by the invention, the encryption process is complex and the security degree is high through encryption of the public key of the networking wallet server and decryption and signature of the private key of the non-networking wallet server, and the networking wallet server and the non-networking wallet server can only communicate through two-dimension code scanning, so that the security is further improved. Further, by arranging the two scanning devices and the display device, scanning display can be automatically performed, so that the automatic scanning device is high in automation degree and convenient to use.

In a further preferred embodiment of the present invention, a peep-proof housing may also be provided external to the non-networked wallet server 200 and the networked wallet server 200. Of course, peep-proof films may be attached to the display screens of the first display device 120 and the second display device.
