Embodiment 1

[0056] figure 1 It is a schematic flowchart of a data storage method provided by the embodiment of the present application. The method can be as follows.

[0057] Step 101: Determine the first check value of the first data version of the target object.

[0058] In the embodiment of this application, the target object here can be any form of data, it can be a business form, a book manuscript, a software source code; it can also be a set of pictures, a piece of music, a video, No specific limitation is made here.

[0059] The data version of the target object here may refer to the different data content evolved during the entire life cycle of the target object, and an identification can be set for each data content, which can be called the version identification of the data version.

[0060] For example: for a video, each part (or each season) of the video can be called a data version, assuming that the first part of video A corresponds to data version 1.0, then the second pa...

Embodiment 2

[0105] Based on the same inventive idea, image 3 It is a schematic flowchart of a data verification method provided in the embodiment of the present application. The method can be as follows.

[0106] Step 301: Receive a data verification request.

[0107] The data verification request includes the version identifier of the data version of the data to be verified and the verification value obtained based on the data content of the data to be verified.

[0108] In step 301, the execution subject of the embodiment of the present application may be a blockchain or other devices, which are not specifically limited here.

[0109] Specifically, when the data demander receives the data provided by the data provider, it can regard the provided data as the data to be verified, and determine the version identification of the data version of the data to be verified, and based on the obtained data to be verified The data content of the data is calculated to obtain the verification val...

Embodiment 3

[0124] Figure 5 It is a schematic flowchart of a data traceability method provided in the embodiment of this application. The method can be as follows.

[0125] Step 501: Receive a data backtracking request.

[0126] The data traceback request includes a version identifier of the first data version of the data to be traced back.

[0127] In step 501, when the evolution process or evolution history of the target object needs to be searched, the operation of the embodiment of the present application can be started, that is, a data traceback request is sent, and the data traceback request includes the version of the first data version of the data to be traced back logo.

[0128] The version identifier of the first data version here may be the version identifier of the current data version, or the version identifier of any data version, which is not limited here.

[0129] Here, the version identifier of the first data version is used to determine the starting point of the tra...

Abstract

The invention discloses a data storage method and device, a data check method and device, and a data tracing method and device. The data storage method comprises the steps of determining a first check value of a first data version of a target object, and searching for a second check value of a second data version, adjacent to the first data version, of the target object; and creating data blocks according to the first check value and the second check value, and storing the data blocks in a block chain. The first check value of the first data version of the target object is stored in the block chain in a data block form; the block chain cannot be tampered, so that whether data contents corresponding to the first data version are modified or not can be verified through the first check value stored in the block chain when a data demander obtains the data contents corresponding to the first data version of the target object, and then the authenticity of the data contents corresponding to the first data version is determined; and therefore, the problem that the authenticity of the data contents cannot be determined due to the fact that the data contents are easily tampered is effectively solved, and the data analysis efficiency of the data demander is improved.

Description

technical field [0001] The present application relates to the technical field of Internet information processing, and in particular to a method and device for data storage, data verification, and data traceability. Background technique [0002] In the digital information age, data is no longer a cold text record, but an information resource that contains production value. In order to accurately analyze the information resources contained in the data, it is necessary to ensure the authenticity of the data storage. That is to ensure that the data stored in the database is the original data. [0003] The so-called data traceability can be understood as recording the evolution information and evolution processing content of the original data throughout the life cycle (from generation, dissemination to extinction). Then through the research on the original data, it is possible to track the evolution of the original data throughout the life cycle and determine the data traceabil...
