If the first permission level is larger than or equal to the second permission level, the access user passes the verification and is allowed to access, and if the first permission level is smaller than the second permission level, the permission verification does not pass.
The invention provides a data exchange platform based on electronic files and electronic archives, as shown in fig. 2, comprising:
step 1: the method comprises the steps of obtaining an electronic file stored in a preset service node at regular time, and obtaining service node information of the service node at the same time;
step 2: generating first exchange data corresponding to the service node based on the electronic file and the service node information;
and 3, step 3: acquiring second exchange data pre-received by the file node;
and 4, step 4: performing exchange verification on the second exchange data according to the first exchange data based on a timestamp technology and a digital summarization technology;
and 5: and if the data passes the exchange verification, carrying out corresponding data exchange.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
