In other embodiments, the user information may further include an identification number of the user, an account number, a device identification code of the mobile terminal, a work unit, a home address, and the like.
In one embodiment, the electronic device 1 performs an emergency warning on the user through an emergency warning program installed on the mobile terminal 3. When the user starts the emergency early warning program for the first time through the mobile terminal 3, the user information is required to be used for registration, and after the registration is successful, the early warning of the emergency can be received through the mobile terminal 3. When a user registers, the electronic apparatus 1 establishes a communication connection with the mobile terminal 3 through a content distribution network, and collects information of each user through the mobile terminal 3.
In an embodiment, the mobile terminal 3 has a private key and a public key, wherein the public key is to be generated by encrypting the private key. The mobile terminal 3 encrypts the user information through the public key and then sends the encrypted user information to the electronic device 1, and the electronic device 1 writes the encrypted user information into the block chain 100.
