Description

How to protect mobile phone information content

technical field

The invention relates to the communication field, in particular to a method for keeping mobile phone information secret.

Background technique

At present, some mobile phones have encryption functions, which are mainly divided into two types of encryption. One is the encryption of information, which is mainly protected by setting a password for one piece of information or multiple pieces of information. The protected information is still kept in the information list. When anyone To open the encrypted information, you need to enter a password, usually a four-digit numeric password. Although this encryption protection method can play a certain role, there are still deficiencies in the protection of privacy. First, the encrypted information is still kept in the list, so that even if you cannot see the content, you can still know who the sender or caller is. Basic information such as who, sending time or call time; Secondly, even if there is password encryption protection, there is a risk of being deciphered. After all, the encryption level of four digits is not enough, and the probability of being deciphered is relatively high. The other is to lock the specified information to prevent accidental deletion. Everyone can browse the information, but it cannot be deleted. Moreover, most information encryption can only encrypt text messages and phonebooks at present, and other information such as call records, pictures, and multimedia information cannot be encrypted.

For the idea of information encryption, we can continue to dig deeper. The current encryption form is encryption but not encryption, which cannot effectively keep important and key information confidential. Many deep-seated encryption needs of users cannot be met. More effective encryption methods are needed to meet the needs of users. In today's era of pursuing privacy, monotonous encryption functions have long been unable to meet people's inner demands for truly protecting important information.

Contents of the invention

The purpose of the present invention is to provide a method for protecting mobile phone information content, which can protect personal information to the greatest extent.

The invention protects the information content of the mobile phone by encrypting all the information associated with the user's set phone number.

Specifically, the method for protecting mobile phone information content of the present invention comprises the following steps:

The user enters the set phone number associated with the information to be encrypted into the encrypted number list;

scan said list of encrypted numbers;

The information associated with all set phone numbers in the encrypted number list is encrypted and stored in a memory such as a mobile phone SIM card or a mobile phone memory.

In addition, the present invention can further improve the effect of protecting mobile phone information by hiding the information associated with the set phone number.

Wherein, the step of hiding the encrypted information includes that the mobile phone checks in real time whether the phone number in the incoming call or text message is the set phone number in the encrypted number list, and if it is found, it does not respond.

Method of the present invention also comprises the following steps:

The user presets the encrypted password;

Check the encrypted password entered by the user. When the encrypted password entered matches the encrypted password set, the encrypted number list accepts the user's set phone number input, otherwise it does not accept the user's set phone number input.

Wherein, the information includes all information associated with the set phone number, such as short messages, multimedia messages, communication records, business card holders and the like.

Among them, the encrypted information is restored by verifying the input password and decrypting the encrypted information, that is to say, after inputting the correct password and decrypting, the user can browse the encrypted information.

The effect of the invention is: when a set number calls or a short message, the information is hidden in a confidential state, and the mobile phone does not make any response, thereby improving the confidentiality effect of the information.

The present invention will be described in further detail below according to the accompanying drawings.

Detailed ways

The invention protects the information content of the mobile phone by encrypting all the information associated with the number set by the user.

More specifically, realize the method of the present invention through the following steps:

The user enters the set phone number associated with the hidden information that needs to be encrypted into the encrypted number list, so that the set phone number can be used to encrypt the relevant information;

Scan the entire encrypted number list, that is, the encrypted information module or the mobile phone program automatically traverses the entire encrypted internal table, and traverses all relevant information in the encrypted number list;

The information associated with all set phone numbers in the list is encrypted and stored in a memory, and the memory is a mobile phone SIM card or a mobile phone memory.

In order to achieve a more confidential effect, the mobile phone can not respond to the set phone number when an incoming call or a text message is received, thereby achieving the effect of improving the confidentiality by hiding the information of the incoming call and incoming text message. For the information of hidden incoming calls and incoming text messages, only after entering a specific viewing module can viewing and browsing be performed. That is to say, the present invention utilizes the encrypted information module to check in real time whether the phone number in the incoming call or short message is the set phone number, and once the two are found to be the same, no response is made, thereby realizing the hiding of information.

On the other hand, the present invention can also store the encrypted information in a hidden area of the memory so as to hide the encrypted information.

The method of the present invention also includes the step of hiding the encrypted information.

The information described in the present invention includes all information associated with the set phone number, usually including short messages, multimedia messages, communication records, and name card holders.

Fig. 1 has shown the flow chart that realizes above-mentioned method of the present invention, as shown in Fig. 1, the flow process that realizes method of the present invention comprises: (1) input password; (2) judge whether input password is identical with setting password, continue if input correctly In the next step, if it is incorrect, the process will end; (3) The user enters the encrypted number list, and can add, delete, and edit numbers; (4) After the setting is completed, the program automatically traverses the entire encrypted number list, and will be displayed in the number list All associated information is traversed; (5) All traversed information is encrypted and hidden. In addition, information encryption can adopt displacement encryption or other simple encryption algorithms, so as to ensure that the information stored on the SIM card cannot be seen after changing the mobile phone.

In addition, in order to prevent others from abusing encryption and concealment, the method of the present invention also includes the following steps:

The user presets the encrypted password;

Check the encrypted password entered by the user. When the encrypted password entered matches the encrypted password set, the encrypted number list accepts the user's set phone number input, otherwise it does not accept the user's set phone number input.

In addition, the present invention utilizes the encrypted information module to restore encrypted and hidden information.

That is to say, the encrypted and hidden information needs to be viewed, edited and deleted in a specific module. Fig. 2 is a flow chart of the method for viewing, editing and deleting encrypted hidden information of the present invention. As shown in Figure 2, the user checks, edits and deletes the encrypted hidden information as follows: (1) input password; End this process; (3) the user enters the encrypted information viewing module, and can view all encrypted hidden information; (4) in the encrypted information viewing module, the user can edit and delete the encrypted information.

When the user uses a mobile phone with this design, after the encryption process is performed, the encrypted information will be hidden from the information list. Only after the user enters the password on a specific interface can the encrypted information be viewed. In this way, when other people look at the user's mobile phone, they will not know the existence of encrypted information at all, which also protects the user's personal encrypted information to the greatest extent. The invention changes and perfects the encryption method of the existing mobile communication terminal, can deeply satisfy the user's demand for encrypted information, fully protect the user's privacy, confidentiality or other sensitive information, and bring the user a safe use experience.
