For example, a high-pass chip itself has a Secure File System (SFS) area, which is a portion of the inaccessible memory partitioned from an Embedded File System (EFS) area. If the terminal is the system terminal, a small section of area is divided from a memory area of the terminal to serve as an un-suspended file system (umount) area, and the small section of area serves as a security domain of the terminal, and the security domain of the terminal cannot perform mount operation, namely cannot be mounted to be readable and writable. The dual-system terminal has two independent memory spaces, and one of the two memory spaces is selected as a safe storage space. The safe storage space is used for storing the communication information for differential encryption, and the safety of the communication information for differential encryption is ensured.

It should be noted that the differentiated decryption matching instruction is preset to be similar to the unlocking instruction of the terminal, and the privacy and safety of the terminal communication information are further ensured by performing the matching authentication on the differentiated decryption matching instruction on the terminal.
Fig. 2 is a block diagram of a terminal for implementing data processing according to the present invention, as shown in fig. 2, including: a differentiation encryption unit and a decryption display unit; wherein,
the differential encryption unit is used for carrying out differential encryption on the obtained communication information through the differential identification;
and the decryption display unit is used for carrying out differential decryption when the communication information is displayed.

Preferably, the differential encryption unit is specifically configured to encrypt the obtained communication information with an IMEI or a MAC address of the terminal or an IMSI number of an SIM card loaded by the terminal as the differential identifier and with the differential identifier as the encryption parameter.
The terminal also comprises an information storage unit which is used for storing the communication information which is encrypted in a differentiation way and is completed by the differentiation decryption unit in a safe storage space.

301, carrying out differential encryption on the general encrypted communication information; specifically, the unique identifier of the terminal or the unique identifier of the SIM card loaded by the terminal is used as an encryption parameter for encryption, that is, only the terminal with the same unique identifier is configured to perform the decryption process.
It should be noted that, in practical applications, the unique identification information is generally encoded and decoded accordingly, i.e., no plaintext is used for display.
Step 302, after completing the differential encryption, the terminal deletes the communication information of the universal encryption; that is, only the differentially encrypted communication information is stored in the terminal, and the other terminals cannot obtain the unique identifier for decryption, so that decryption cannot be performed, and the security of the communication information is ensured.
Step 303, storing the differentially encrypted communication information in a safe storage space of the terminal; specifically, the secure storage space is a storage space that cannot be mounted as readable and writable storage space. For example, a high-pass chip has its own SFS area, which is a portion of inaccessible memory partitioned from an Encrypted File System (EFS) area. The mobile phone with the security domain divides a small section of area on the memory area as an un-mounted file system (umount) area, and the area cannot carry out mount operation, namely cannot be mounted as readable and writable. In a dual system, there are two independent memory spaces, and the secure storage space occupies a dedicated memory.

Step 401, the receiving end performs receiving end differentiation encryption on the received general encrypted communication information.
Step 402, after completing the differential encryption, deleting the received general encrypted communication information.
And step 403, storing the differentially encrypted communication information in a secure storage space of the terminal.
And step 404, when the communication information is displayed, the terminal performs differential decryption and display through decryption information corresponding to the differential encryption.

Here, different random numbers may be used each time to secure the communication information during transmission. In addition, when the general encrypted communication information is sent to the receiving end, according to the processing method in the prior art, the decryption public key of the general encryption is carried in the sending process.
601, a sending end carries out differential encryption on the general encrypted communication information, and encryption is carried out by taking the sent unique identifier as a parameter in an encryption algorithm in the encryption process; for example, an IMEI number or an MEID number is used as a parameter for encryption, and decryption information is added to a message file after encryption and is used for identification in a decryption process. It should be noted that, for the decryption process, which completely corresponds to the encryption process, the encryption parameter is encrypted by the unique identifier, and the decryption information decrypted by the unique identifier is inevitably provided in the decryption information for the terminal that allows decryption, so as to perform differential decryption.
And step 602, after differential decryption is performed on the decryption information, obtaining and displaying the communication information.

step 701, decrypting the differentially encrypted communication information according to the decryption information; the decryption information is generated by the unique identifier of the differential encryption of the sending end when the sending end carries out differential encryption, so that the decryption can be realized. For the decryption information of other terminals, the transmitted unique identifier cannot be obtained, and the decryption information capable of decrypting the differentially encrypted communication information cannot be generated.
Step 702, after completing the decryption of the communication information differentially encrypted by the sending terminal, deleting the analysis information, and performing receiving terminal differential encryption on the decrypted communication information; namely, the IMEI number or MAC address of the receiving terminal and the IMSI number of the SIM card are used as encryption parameters to carry out differential encryption of the receiving terminal.
