Preferred embodiment of the invention

In the embodiment of the present invention, a private information field is added to the contact information of the mobile terminal, and the content of the private information field is obtained, and the content of the private information field is encrypted by using a reversible encryption algorithm and stored in the encrypted file system.

The basic processing flow of the method for storing contact private information in the embodiment of the present invention, as shown in FIG. 1 , includes the following steps:

Step 101: Add a private information field to the mobile terminal contact information.

Optionally, a private information field may be added to the contact card of the mobile terminal, or the phone book, or the contact information of the address book.

Step 102: Acquire the content of the private information field.

Here, the content of the private information field may be obtained by using a short message, a call record, a business card holder, a notepad, etc., or the content of the private information field may be manually input;

Optionally, the option of “save to private information” is added to the options of the fields such as the short message, the call record, the business card holder, and the notepad, and the content to be saved is stored by “save to private information”;

The content of the private information field of a contact may be one or more, and the content of the private information field includes: a bank card number, a payment password, a private phone information, a short message information, a notebook information, and the like, which are not desired by other people. Personal information.

Step 103: The content of the private information field is encrypted by a reversible encryption algorithm and stored in an encrypted file system.

Optionally, the content of the obtained private information field is encrypted by using a reversible encryption algorithm such as DES or 3DES; and the content of the encrypted private information field is stored in the encrypted file system of the mobile terminal; the storage path of the content of the private information field may be Is: private\user1\user information1, private\user1\information2, private\user2\user information1...;

In the related art, the contact information of the mobile terminal is stored in the database, and each contact in the database corresponds to an index number; when the content of the private information field is stored, the index number of the contact corresponding to the content of the stored private information field is set. The index number of the contact corresponding to the content of the set storage private information field is the same as the index number corresponding to the contact stored in the database;

Here, after storing the content of the encrypted private information field to the encrypted file system of the mobile terminal, the storage path of the content of the stored private information field and the content of the private information field may be separately set as a hidden attribute or an invisible attribute to prevent Others view the contents of the private information field through other external means.

Before the step 102 is performed for the first time, the method further includes: registering user information related to the private information field;

The user information includes: password information and password prompt information; the password information is saved to an encrypted file system of the mobile terminal by using an irreversible encryption algorithm such as SHA or MD5, and the password prompt information is saved to the mobile by using a reversible encryption algorithm such as DES or 3DES. The encrypted file system of the terminal is prevented from being cracked;

The password information is used to encrypt the content of the obtained private information field and view the content of the obtained private information field;

The password prompt information includes: an answer to the prompt information for retrieving the password, and other mobile terminal numbers except the mobile terminal's own number; when the password is forgotten or the password is lost, the password can be retrieved in two ways. The first type is to enter the registration. When the user information is saved, the answer information of the retrieved password is correct. When the answer of the input prompt information is correct, the mobile terminal number that sends the temporary password is input according to the prompt of the mobile terminal, and the temporary password sent by the mobile terminal to the input mobile terminal number is checked; The second type is to send a temporary password to the mobile terminal number other than the mobile terminal's own number saved when registering the user information; the mobile terminal user can view the content of the private information field after inputting the temporary password, and reset the password information;

Here, it is also possible to set the time when the temporary password expires, that is, the mobile terminal from the mobile terminal to the input. The time at which the terminal number sends the temporary password begins to be calculated, and the temporary password expires for a long time; the time when the temporary password expires can be flexibly set according to actual needs.

After performing step 103, the method further includes:

Step 104, viewing contact information;

Optionally, when the private information field is opened, the content of the private information field is implicitly displayed by using a special symbol; that is, the content of the private information field is displayed by a symbol such as “******”, and the content of the private information field is displayed. If it is empty, there is no display; after entering the password information, the content of the private information field is displayed; after the password information is input, the contents of the private information may be added, deleted, modified, etc.; The content of the information field is empty, and you do not need to enter password information when you need to add private information.

The detailed processing procedure of the method for storing contact private information in the embodiment of the present invention, as shown in FIG. 2, includes the following steps:

Step 201: Add a private information field to the mobile terminal contact information.

Step 202: Register user information related to the private information field;

The encrypted file system of the terminal is prevented from being cracked by unscrupulous personnel;

The password information set here is “000000”, which is used to encrypt the content of the obtained private information field and view the content of the obtained private information field;

The set password prompt information includes: the answer of the prompt information for retrieving the password is “111111”, and the mobile terminal number other than the mobile terminal's own number is 13922222222.

Step 203: Obtain the content of the private information field.

Here, the option of "save to private information" is added to the option of the short message field, and after receiving the short message of the A contact, the content of the short message is stored through the "save to private information" option.

Step 204: Encrypt and store the content of the obtained private information field;

Optionally, the outputted short message content is encrypted by using the MD5 algorithm, and the content of the encrypted private information field is stored in the encrypted file system, and the storage path is private\user1\user information1; setting the index of the A contact in the encrypted file system No. The index number set is the same as the index number corresponding to the A contact stored in the database; the content of the stored private information field and the storage path of the private information field are hidden attributes to prevent others from viewing the privacy through other external channels. The content of the information field.

Step 205: View A contact information.

Optionally, when the private information field of the A contact information is opened, the content of the private information field is displayed with a symbol such as “******”; after the password information “000000” is input, the content of the private information field is displayed;

When the password information is forgotten, enter the prompt information of the password to be retrieved when registering the user information: "111111", according to the prompt of the mobile terminal, enter the mobile terminal number that sends the temporary password as "13533333333", and check that the mobile terminal sends to "13533333333". Temporary password, after entering the temporary password, you can view the contents of the private information field and reset the password information.
