The first file can be uploaded to a cloud database for storage through a cloud database administrator, and the rule setting and the authority distribution can be carried out on the first file in the cloud database. The rule setting is mainly to set a specific operation flow when the first file is required to be accessed. The authority distribution mainly sets an identity information list of the user terminals capable of accessing the first file, that is, sets which user terminals can access the first file. When the authority of the user side needs to be verified, the authority of the user side can be verified through the identity information of the user side. When the user side needs to access the first file, an access request for the first file can be sent to the cloud database.
S102, receiving a second file corresponding to the first file issued by the cloud database according to the access request; specifically, the second file may be a document file, a video file, an image file, or the like. The rules set for the first file in the cloud database may include: when the cloud database receives an access request aiming at a first file sent by a user side, the cloud database automatically generates a second file corresponding to the first file, automatically inserts prompt information, characteristic information of the first file (unique identification information of the first file or path information of the first file) and the like into the second file, and then sends the second file to the user side. The prompt message may be that the first document is protected and the identity information of the user side needs to be verified. The prompting message can be in the form of characters, videos, pictures and the like. The user side can receive a second file corresponding to the first file issued by the cloud database according to the access request after sending the access request aiming at the first file to the cloud database.
S103, acquiring identity verification information of the user side according to the second file; specifically, the identity verification information of the user side is information obtained by verifying the identity information of the user side by the cloud database. After the user side receives the second file, the user side can analyze the second file, and under the prompt of the prompt information of the second file, the identity information of the user side can be sent to the cloud database for authority verification. The rule set for the first file in the cloud database may further include: after the cloud database receives the identity information of the user side, the identity information of the user side can be matched with an identity information list of the user side capable of accessing the first file, when the identity information of the user side is in the identity information list of the user side, the identity information of the user side passes verification, and the user side has the authority of accessing the first file. When the identity information of the user side is not in the identity information list of the user side, the identity information of the user side is not verified, and the user side does not have the authority of accessing the first file.
