Step 206: and sending the encrypted data, the data display setting parameter set and the first identity identification of the first data receiver to a server.
After receiving the encrypted data, the data display setting parameter set and the first identity identifier of the first data receiver, the server generates a first data browsing link and a first data browsing key according to the encrypted data and the data display setting parameter set, and sends the first data browsing link and the first data browsing key to the first data receiver corresponding to the first identity identifier.
The first data receiving party accesses the server to view data through the received first data browsing link and the first data browsing key, and when the data are displayed on the first data receiving party, if the server detects that the management mechanism of the encrypted data contained in the data display setting parameter set is that the encrypted data are transmitted to the first data receiving party and then destroyed on the server side, the content is automatically destroyed. And if the server detects that the management mechanism of the encrypted data contained in the data display setting parameter set is that the encrypted data is transmitted to the first data receiver and then stored on the server side, temporarily storing the encrypted data. The time length for temporarily storing the encrypted data at the server side can be set by a sender user, and the server side can also control the temporary storage time length of the encrypted data.
It should be noted that the first data receiver may be a single mobile terminal or a group of mobile terminals.
Step 207: and receiving a data forwarding request sent by a first data receiver.
If the first data receiver is a mobile terminal group, any data receiver in the mobile terminal group may forward the checked data, and the specific forwarding process is as shown in steps 207 to 209.
And the data forwarding request carries the second identity of the forwarding object.
After the first data receiver finishes data checking, if the management mechanism of the encrypted data is that the encrypted data is transmitted to the first data receiver and then stored on the server side, a data forwarding option can be displayed in the data checking interface, and a user of the first data receiver can determine whether to trigger the option to forward the data according to requirements. If the management mechanism of the encrypted data is that the encrypted data is destroyed at the server side after being transmitted to the first data receiver, the data forwarding option in the data viewing interface is in a forbidden state or is not set in the data viewing interface.
Step 208: and responding to the data forwarding request, and determining whether the management mechanism of the encrypted data is stored on the server side after the encrypted data is transmitted to the first data receiver.
If yes, step 209 is executed, if no, no response is made to the data forwarding request.
Step 209: and if so, sending a data sending instruction to the server.
And the data sending instruction carries the second identity.
And after receiving the data sending instruction, the server generates a second data browsing link and a second data browsing key according to the encrypted data and the data display setting parameter set, and sends the second data browsing link and the second data browsing key to a second data receiving party corresponding to the second identity, wherein data downloading is prohibited in an interface corresponding to the second data browsing link. After the server forwards the data to the second data receiver, the server can immediately destroy the temporarily stored data, or continue to temporarily store the data so as to forward the data after receiving the data sending instruction of the sender again.
According to the data transmission method provided by the embodiment of the invention, the data to be transmitted is encrypted, so that the data can be prevented from being leaked after being intercepted illegally in the transmission process; the method comprises the steps of obtaining a data display setting parameter set by receiving second operation on a display mode of encrypted data and setting the display mode according to the second operation, sending the encrypted data, the data display setting parameter set and a first identity mark of a first data receiver to a server, and sending a first data browsing link and a first data browsing key to the first data receiver corresponding to a first identity mark after the server generates the first data browsing link and the first data browsing key according to the encrypted data and the data display setting parameter set; on the other hand, the encrypted data is associated with the first data browsing link, and the browsing link only supports data browsing to prohibit data downloading, so that data leakage caused by forwarding the data to a third party after being downloaded by the first data receiver can be avoided. In addition, the data transmission method provided by the embodiment of the invention can also be used for forwarding the data to the second data receiver by the server under the condition of authorization of the data sender, so that the data forwarding efficiency can be improved compared with the data sent by the second data receiver to the sender.
