Embodiment 1

[0042] A real-time certificate storage system for electronic data based on block chain 20. This system is installed in electronic equipment and stores the operating data of electronic equipment in real time. The electronic equipment has a unique number. Please refer to the attached figure 1 , this example includes:

[0043] The data buffer module 11, the incremental electronic data of the operation data of the electronic equipment is written into the data buffer module 11 in real time, and the data buffer module 11 has several data buffers. Several data buffers are used interleavedly, and for the data flow generated in real time, the data can be received without omission, ensuring the smooth and complete reception of electronic data.

[0044] The data storage module 12 is connected with the data buffer module 11. When the buffer area of ​​the data buffer module 11 is filled, the electronic data therein is taken out, and the serial number and time stamp of the associated electr...

Embodiment 2

[0089] A real-time certificate storage system for electronic data based on blockchain 20. This embodiment adds a backup storage module 15 on the basis of Embodiment 1 to further improve the security of electronic data and avoid loss of electronic data. Please refer to the attached Image 6 , the backup storage module 15 is connected to the data storage module 13 , and when the data storage module 13 stores data, it makes a copy of the data and sends it to the backup storage module 15 .

[0090] The working method of backup storage module 15 comprises:

[0091]Step E1) The backup storage module 15 includes a data receiving unit 151 and several data storage units 152. The data receiving unit 151 is connected to the data storage module 13 to receive the data sent by the data storage unit 152. Several data storage units 152 are connected to the data receiving unit 152. The unit 151 is connected, and the data storage unit 152 divides its storage space into space segments of a pres...

Abstract

The invention relates to the technical field of block chains, in particular to an electronic data real-time evidence storage system and method based on a block chain, and the system comprises a data buffering module which is provided with a plurality of data buffering regions; a data storage module which is used for extracting the electronic data, the serial number of the associated electronic equipment and the timestamp as data blocks when the buffer area of the data buffer module is fully written, extracting a hash value from the data blocks and the hash value of the previous data block, and storing the extracted hash value; an uplink module which packages all the Hash values generated by the data evidence storage module in the period into an evidence storage packet, associates the Hash values of the evidence storage packet with serial numbers and timestamps and then uploads the Hash values to a block chain for storage; and a data storage module which is used for obtaining and storing the data blocks, the hash values, the evidence storage packets, the block heights and the block hash values in a linear storage mode. The method has the substantive effects that the credibility of the operation data of the electronic equipment is powerfully improved, and the authenticity of the electronic data is reliably guaranteed through the proof of workload.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a system and method for real-time electronic data deposit certificates based on block chains. Background technique [0002] With the development of electronic technology and information technology, more and more electronic devices are used in various fields of production and life. Electronic equipment can automatically and even intelligently complete work content independently, and operation data will be generated during the execution process. The operation data of electronic equipment includes control data or monitoring data, and the control data and monitoring data can record and restore the operating status of the equipment. These data not only provide a data reference for improving electronic equipment, but also are an important basis for finding the cause of the accident or determining the responsibility for the accident after a failure or accident occurs. Although ele...
