Enterprise data sharing method and system based on big data

The invention provides an enterprise data sharing method and system based on big data, and relates to the technical field of data sharing. The system comprises a data receiving module used for receiving to-be-shared data; the data analysis module is used for acquiring propagation data of the to-be-shared data based on a big data technology, and performing circulation analysis on the propagation data of the to-be-shared data; the authority authentication module is used for acquiring identity information of a data uploader corresponding to the to-be-shared data and performing identity authentication on the data uploader; and the data storage module is used for storing the to-be-shared data in the shared database. According to the method, the process of uploading the to-be-shared data to the shared database is managed by analyzing the propagation data of the to-be-shared data, authority authentication is performed on the data uploader, and the storage record data and the authority data are added to the to-be-sha
