8. The computer data encryption method according to claim 7, wherein the specific steps of the computer obtaining the identity information of the intelligent terminal and generating the corresponding public key and the public key encryption algorithm include:
the communication module establishes communication connection with the intelligent terminal, acquires a user wechat account logged in by the intelligent terminal, and feeds the user wechat account back to the verification module;
the verification module verifies the user wechat account number and judges whether the user wechat account number is one of the user identity information white lists in the storage module, and if so, the user wechat account number is transmitted to the key generation module;
the key generation module converts the user WeChat account number into a decimal number according to an ASCII character table, iterates the decimal number for N times through a chaotic iterative algorithm to obtain a key factor Pn and judges whether the key factor Pn is a prime number, if not, adds 1 to the key factor Pn to judge whether the number added with 1 is a prime number, if not, adds 1 to the number added with 1 again to repeat the operation process of adding 1 until the number obtained after operation is a prime number, and expresses the prime number by p;
the key generation module iterates the obtained decimal number for N +1 times through a chaotic iterative algorithm to obtain a key factor Qn and judges whether the key factor Qn is a prime number, if not, the key factor Qn is subjected to 1 addition operation, whether the number subjected to 1 addition is a prime number is judged, if not, the number subjected to 1 addition is subjected to 1 addition operation again, the 1 addition operation process is repeated until the number obtained after the operation is a prime number, and the prime number is represented by q;
and selecting a public key e, enabling 1< e < (p-1) > q-1 and the e and the (p-1) > q-1 to be in prime number relationship, and calculating a public key, a private key, a public key encryption algorithm and a private key decryption algorithm corresponding to the user wechat account number by utilizing the e, the p, the q and an RSA algorithm.
9. The computer data encryption method according to claim 8, wherein a data information list is stored in the computer, and the intelligent terminal generates the data information requested to be transmitted through the data information list.
10. A computer-readable storage medium, characterized in that it stores a computer program which, when executed, implements the computer data encryption method according to any one of claims 5 to 9.
