4) The called number A shares the contact link of the called number A with the calling number B2;
5) The calling number B2 applies for the server to add the called user A into the personal address book through the contact link;
6) The server judges whether to permit the application according to the credit of the user, after the application passes, the blockchain allocates a serial number for the user, adds the user into the blockchain, records the preamble number of the user, and adds the calling number B2 into the contact blockchain table of the called user A;
7) The calling number B2 and the called user A are contacted normally through a short message or a telephone;
8) The calling number B2 sends a plurality of harassing calls or short message applications to the called user A;
9) The called user A defines the calling number B2 contacted with the called user A as a telephone needing shielding to the server, does not accept the contact telephone any more, and verifies whether the number transmission path is tampered, for example: calling number B, calling number C, calling number D. . . Is the transmission path information on the same? If the two types of data are inconsistent, falsification is proved;
the recorded information is stored on each number side of the transmission path, for example, the information of the calling number B2 added into the blockchain is stored on the mobile phone of the called number A, and can be verified later to confirm that the transmission path is not tampered. It can also be determined whether the number following the number is also masked.
10 The server side performs corresponding operation according to the application of the called user A.
11 The calling number B2 (or the subsequent number) sends a crank call or a short message application to the called user A, and is directly shielded by a communication system.
As shown in fig. 1 and 3, the specific flow of privacy protection for the called number a is as follows:
1) The calling number B22 directly calls the called number A of the called user A under the unregistered condition, and hopes to talk with the called number A;
2) The server side verifies to find that the number is not the number on the called mobile phone number blockchain, refuses the request and prompts that the number is not registered (not registered on the called mobile phone number blockchain);
3) The calling number B22 knows the contact way of the called user A through the calling number B2 (intermediate user), and hopes to add the contact way into the personal address book;
4) Calling number B2 shares the contact link of called number A with calling number B22;
5) The calling number B22 applies for the server to add the called user A into the personal address book through the contact link;
6) The server judges whether to permit the application according to the credit of the user, after the application passes, the blockchain allocates a serial number for the user, adds the user into the blockchain, records the preamble number of the user, and adds the calling number B22 into the contact blockchain table of the called user A;
7) The calling number B22 and the called user A are contacted normally through a short message or a telephone;
8) The calling number B22 sends a plurality of harassing calls or short message applications to the called user A;
9) The called user A defines the calling number B2 contacted with the called user A as a telephone needing shielding to the server, does not accept the contact telephone any more, and verifies whether the number transmission path is tampered, for example: calling number B, calling number C, calling number D. . . Is the transmission path information on the same? If the two types of data are inconsistent, falsification is proved;
the recorded information is stored on each number side of the transmission path, for example, the information that the calling number B22 joins the blockchain is on the mobile phones of the called number A, the calling number B and the calling number B2, and can be verified later to confirm that the transmission path is not tampered. It can also be determined whether the number following the number is also masked.
10 The server side performs corresponding operation according to the application of the called user A.
