Information storage method, device, and computer-readable storage medium

A server, comprising:

• one or more processors, memory coupled to the one or more processors, and a plurality of program instructions stored in the memory that, when executed by the one or more processors, cause the server to perform the following operations:
• receiving an information storage request sent by a terminal device, the information storage request carrying a first user identifier, an account address, and a to-be-stored ciphertext, wherein the account address corresponds to a balance amount;
• performing identity authentication on a user according to the first user identifier;
• generating a serving end serialization factor according to preset configuration information after the identity authentication succeeds;
• obtaining a plurality of ciphertext fragments of the to-be-stored ciphertext according to the serving end serialization factor and the to-be-stored ciphertext, wherein obtaining the plurality of ciphertext fragments comprises randomly combining characters included in the to-be-stored ciphertext with random characters using a preset serialization algorithm and the serving end serialization factor, and wherein the serving end serialization factor is generated by the server;
• storing the account address corresponding to the first user identifier, and respectively storing, corresponding to the account address, the plurality of ciphertext fragments into different ciphertext databases;
• obtaining, according to a target account address, at least two ciphertext fragments corresponding to the target account address when receiving a ciphertext obtaining request sent by the terminal device, the ciphertext obtaining request carrying the target account address;
• deserializing the at least two ciphertext fragments according to the serving end serialization factor, to obtain a ciphertext corresponding to the target account address;
• and
• sending the ciphertext to the terminal device, so that the terminal device decrypts the ciphertext according to a second encryption password that is input by the user, to obtain a private key corresponding to the ciphertext.

A non-transitory computer readable storage medium storing a plurality of instructions in connection with a server having one or more processors, wherein the plurality of instructions, when executed by the one or more processors, cause the server to perform a plurality of operations including:

• receiving an information storage request sent by a terminal device, the information storage request carrying a first user identifier, an account address, and a to-be-stored ciphertext, wherein the account address corresponds to a balance amount;
• performing identity authentication on a user according to the first user identifier;
• generating a serving end serialization factor according to preset configuration information after the identity authentication succeeds;
• obtaining a plurality of ciphertext fragments of the to-be-stored ciphertext according to the serving end serialization factor and the to-be-stored ciphertext, wherein obtaining the plurality of ciphertext fragments comprises randomly combining characters included in the to-be-stored ciphertext with random characters using a preset serialization algorithm and the serving end serialization factor, and wherein the serving end serialization factor is generated by the server;
• storing the account address corresponding to the first user identifier, and respectively storing, corresponding to the account address, the plurality of ciphertext fragments into different ciphertext databases;
• obtaining, according to a target account address, at least two ciphertext fragments corresponding to the target account address when receiving a ciphertext obtaining request sent by the terminal device, the ciphertext obtaining request carrying the target account address;
• deserializing the at least two ciphertext fragments according to the serving end serialization factor, to obtain a ciphertext corresponding to the target account address;
• and
• sending the ciphertext to the terminal device, so that the terminal device decrypts the ciphertext according to a second encryption password that is input by the user, to obtain a private key corresponding to the ciphertext.
