4. The internet-based contract file cloud synchronization method as recited in claim 3, wherein the process of converting the device into an authorized device includes:
after the synchronous identification in the shared folder in the synchronous transfer database is acquired, the synchronous identification is stored in a set encryption area, the identity identification is input in the encryption area for verification, the synchronous identification is acquired after the verification is passed, and the equipment acquiring the synchronous identification is converted into authorized equipment.
5. The internet-based contract document cloud synchronization method of claim 4, wherein the process of historical data set and final contract document generation includes:
the synchronization service between the authorization devices can generate a plurality of historical version contract files, all the historical version contract files are summarized, contract codes are given to each historical version contract file, the summarized historical version contract files form a historical data set, the corresponding contract codes are also stored in the historical data set, a voting mechanism is set, and a final contract file is drawn according to the voting mechanism and synchronized to the cloud server.
6. The internet-based contract file cloud synchronization method as claimed in claim 5, wherein the voting process of the voting mechanism includes:
reading the historical data set, and respectively setting voters in clients and service providers, wherein the clients and the service providers respectively correspond to different client categories and service provider categories, and the service provider categories and the client categories have corresponding voting weights;
and acquiring a plurality of historical version contract files, if a contract principal selects the historical version contract files, regarding the historical version contract files as votes, correlating voting weights of the votes with contract codes of the historical version contract files, adding the acquired voting weights to generate voting coefficients, and selecting the historical version contract file with the highest voting coefficient as a final contract file.
7. The internet-based contract file cloud synchronization method as claimed in claim 6, wherein said security log and corresponding security measure generation process includes:
recording access time, operation behavior, network IP address and unit time access frequency of a contract principal accessing a contract file, and generating a security log according to the access time, the network IP address and the operation behavior;
the network IP address comprises an internal network address and an external network address, and the operation behavior comprises synchronizing a final contract file and acquiring a historical version contract file;
and carrying out risk analysis on the security log through the set risk prediction model to generate corresponding security measures.
