Nine groups of data streams are divided into different open data streams and hidden data streams, the open data streams are filled in the open data stream grid template, the hidden data streams are filled in the hidden data stream grid template, the two groups of grid templates are filled in the storage space, and enterprise information is replaced. Enterprise information of different enterprises in the information storage database is encrypted in sequence, when an external hacker intrudes into the system, only two groups of corresponding grid templates can be seen, but the internal splicing logic is not clear, the safety protection effect of the enterprise information is improved, and the enterprise information is prevented from being stolen by external personnel.
