the transceiver is further configured to establish a 5G transmission network with the first terminal, insert the encrypted sub-data into a slice, and transmit the plurality of slices carrying the sub-data to the first terminal in parallel by the second terminal.

6. The terminal of claim 5, wherein the transceiver is specifically configured to receive first slice information, first IP address information, and first port information sent by the first terminal, access a corresponding plurality of network slices based on the first slice information, and return second IP address information and second port information of the second terminal to the first terminal.

7. A terminal, comprising:

the transceiver is used for sending a data acquisition request to the second terminal, wherein the data acquisition request carries set characters and/or pictures;

the processor is used for pairing the first terminal and the second terminal through authentication information, wherein the authentication information is predetermined by the first terminal and the second terminal; after the authentication information passes, the first terminal and the second terminal are successfully paired;

the transceiver is further configured to access a network slice through a 5G chip, determine first slice information, first IP address information, and first port information of a plurality of network slices that are accessed, and send the first slice information, the first IP address information, and the first port information to the second terminal;

the transceiver is further configured to receive second IP address information and second port information of the second terminal, which are returned by the second terminal;

the transceiver is further configured to receive multiple slices carrying the encrypted sub-data sent by the second terminal;

the processor is further configured to obtain a plurality of corresponding encrypted subdata from the plurality of received slices, query a locally stored insertion rule jointly agreed by the first terminal and the second terminal according to the data obtaining request, and decrypt the plurality of encrypted subdata according to the insertion rule to obtain the plurality of subdata; and combining the plurality of subdata into data according to the splitting information.
