Detailed Description
The invention will be further explained with reference to the drawings.
For example, in the present embodiment, unstructured data storage of the block chain is implemented by FaaS + S3 object storage, and FaaS uses the lambda cloud function of AWS in the following description. FaaS + S3 object storage is a non-service architecture, realizes the transparency and automation of non-structural data storage, and the lambda cloud function supports flexible management, so that required resources can be automatically allocated and expanded, and the development cost and the operation cost are effectively reduced.
In the FaaS + S3 object storage scheme, a user can directly operate the S3 server to store (read) files, and automatically trigger the lambda cloud function to send related information to the blockchain through the S3 service to ensure the reliability of the system, and at the same time, the lambda cloud function records information of users, content, time and the like of each operation to ensure data traceability. In addition, the MD5 check value of the data is transparently realized through a lambda cloud function, and the illegal MD5 value is prevented from being invaded or maliciously uploaded by a user.
In order to ensure that the lambda cloud function is not illegally tampered, the lambda cloud function is safely and reliably operated, the lambda cloud function needs to be checked every time the lambda cloud function is executed, and the function name of the lambda cloud function and the MD5 need to be stored in a block chain in advance. The S3 object memory stores a correspondence table in which lambda function names and source code paths corresponding to the lambda function names one by one are recorded. The cloud function server may obtain a path of the source code from the correspondence table according to the function name, and then obtain the source code corresponding to the function name according to the path of the source code. Since the cloud function server also checks the source code after acquiring the source code, and the check code is already stored in the block chain, this check operation already ensures the reliability of the source code, so that the source code does not need to be also stored in the block chain, but only stored in the object storage of S3.
The blockchain-based unstructured data manipulation method is used for manipulating unstructured data, including but not limited to reading data, storing data, and modifying data. The blockchain-based unstructured data manipulation method may be executable on a blockchain-based unstructured data manipulation system. The unstructured data operating system comprises a cloud function server and an object storage. The cloud function server comprises a memory for storing a computer program and a processor for executing the block chain based unstructured data manipulation method when executing the computer program.
The object storage unit is used for triggering the first cloud function for storing data and sending storage information of a file after storing the file sent by a user terminal, wherein the storage information comprises one or more of a path of the file in the object storage unit, an MD5 value of the file, user information of the file and a timestamp of the file, or is used for triggering modification information of the file after responding to a request sent by the user terminal for modifying the file, wherein the modification information comprises one or more of a path of the file in the object storage unit, an MD5 value of the modified file, user information of the file, a timestamp of the file, or is used for triggering the first cloud function for reading data and sending reading information of the file after responding to a request sent by the user terminal for reading the file, wherein the read information comprises one or more of a path of the file in the object storage unit, an MD5 value of the file, user information of the file, and a time stamp of the file.
