Electronic equipment data credible acquisition and evidence storage method based on blockchain technology

Abstract

The invention discloses an electronic equipment data credible acquisition and evidence storage method based on the blockchain technology, and the method comprises the steps: generating a unique public and private key pair for electronic equipment according to an equipment manufacturer name, an equipment model and an equipment SN number; through a private key signature and public key signature verification mode, guaranteeing that the server can confirm the identity of the device when the data collected by the device is sent to the server in real time, and guaranteeing that the data is not tampered. A strict progressive increase operation sequence number is maintained for each device, and a timestamp synchronization mode is adopted, so that the data uploading sequence of the devices is consistent with the collection sequence. And the data uploaded by the equipment is not lost or deleted in an offline period in a mode of maintaining a strict progressive increase operation sequence number for each piece of equipment. And the server stores the public key of the electronic equipment and is bound with the information of the electronic equipment. The whole process of data from collection to storage is transparent, credible and non-tampering through the block chain and encryption technology.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method for credibly collecting and storing certificates of electronic device data based on block chain technology. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Due to the characteristics of decentralization, openness and transparency, each computing device can participate in database records, and fast data synchronization between computing devices, blockchain technology has been widely used in many fields. to apply. [0003] Electronic equipment such as electronic recorders and surveillance cameras integrate real-time video and audio recording, photography and audio recording, and must ensure data reliability. Existing collection and storage solutions often ...

Problems solved by technology

However, such devices are often maintained by grassroots users and run in a changeable natural environment. There are the following problems: when the device is offline in a weak network environment, the data cannot be uploaded to the server in real time, and the data may be modified before being connected to the network; The inaccurate time of the device leads to disordered data collection sequence, greatly reducing the use value of the data; before the intervention of the superior department, the grassroots personnel may artificially interrupt the recording of the device and artificially delete the data stored locally

On the other hand, when the data is incomplete due to problems such as abnormal shutdown of the equipment, it is often difficult for equipment maintenance personnel to prove their innocence, causing trust issues
