Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

The invention provides a WIFI data protection processing method, a mobile terminal and a storage medium; the invention mainly aims at the situation that the mobile phone is infected with viruses, and then the WIFI receiving and transmitting data of the mobile phone is rewritten, so that the WIFI of the mobile terminal is safer to use.

Referring to fig. 1, the WIFI data protection processing method provided by the invention includes the following steps:

step S100, a WIFI data cache is preset in the mobile terminal, and the WIFI data cache is used for writing in other mobile terminal WIFI data which need to be sent after the WIFI data cache is written in a preset value; otherwise, other WIFI data of the mobile terminal which need to be sent cannot be written.

According to the embodiment of the invention, the WIFI data cache is required to be preset in the mobile terminal and used for the internal security protection of the WIFI data cache, the WIFI data of other mobile terminals are allowed to be written only when the preset value is written in the WIFI data cache, and otherwise, the value of the WIFI data of the mobile terminal cannot be written in. As shown in fig. 3, which is a WIFI data cache schematic diagram of a mobile terminal, only after writing a preset value into the WIFI data cache, other WIFI data of the mobile terminal that needs to be sent can be written, otherwise, other WIFI data of the mobile terminal that needs to be sent cannot be written, so that the mobile terminal cannot send data through WIFI.

Step 200, when each WIFI is to send data, firstly closing the security detection, firstly writing the preset value into the WIFI data cache and writing the data to be sent, and after the WIFI is to send the data and finishes writing, modifying the preset value of the WIFI data cache by other values to enable the WIFI data cache to enter a write protection state so as to prevent from being rewritten by others;

in the embodiment of the invention, when the mobile terminal needs to send WIFI data, the security detection is closed firstly, and then a preset value is written into the WIFI data cache; writing in a value of WIFI data to be sent by the mobile terminal; after the writing is completed, writing values except the preset values into the WIFI data cache again to enable the values of the WIFI data of the other mobile terminals to be unable to be written; to buffer the WIFI data into a write-protected state to prevent overwriting by others.

In the embodiment of the invention, after other mobile terminal WIFI data needing to be sent in the WIFI chip are written in and a preset value is written in the WIFI data cache, the value is read and stored in the memory, and when the mobile terminal WIFI data is detected to be vulnerable to security threat, the mobile terminal WIFI data value stored before is read from the memory and written in the mobile terminal WIFI data.

Namely, when each WIFI transmits data, the data to be transmitted needs to be written into the WIFI data cache, and the step of writing the data comprises the following steps:

closing WIFI data detection;

And step S300, when the WIFI data cache enters a write-protection state, starting security detection on the WIFI data to be transmitted.

And step S400, when the security detection is started, detecting whether the WIFI data cache is written into the preset value or not at regular time, and if so, indicating that the WIFI data of the mobile terminal has security threat.

In the embodiment of the invention, when the security detection is started, whether the WIFI data cache is written into the preset value is detected at regular time; namely, in order to judge whether the WIFI data of the mobile terminal is locally and internally protected, namely, the value of the WIFI data cache is read, if the value is not the preset value (after the data writing of the WIFI to be sent is finished, the preset value of the WIFI data cache is modified by other values); and if not, indicating that the WIFI data of the mobile terminal do not use the internal security protection of the mobile terminal.

When the security protection is used, the WIFI data cache is written into the preset value through the timing detection, and therefore the fact that the mobile terminal WIFI data are rewritten and the security threat exists is indicated.

And S500, when the WIFI data of the mobile terminal has security threat, reading the previously stored WIFI data value of the mobile terminal from the memory, writing the value into the WIFI data cache of the mobile terminal, and retransmitting the value.

In the invention, the WIFI data is restarted to be detected when the write protection state is adopted;

In the embodiment of the invention, after other mobile terminal WIFI data needing to be sent in the WIFI chip are written in and a preset value is written in the WIFI data cache, the value is read and stored in the memory, and the backup scheme is started when the mobile terminal WIFI data is detected to be vulnerable to security threat: and reading the previously stored WIFI data value of the mobile terminal from the memory and writing the WIFI data of the mobile terminal.

Example 2:

referring to fig. 2, the WIFI data protection processing method provided by the invention includes the following steps:

in step S10, a timer is started, and preferably the timeout period of the timer is 1 second.

Setting the timer to perform the security method of the present invention can save resources, which would be too consumed if the timer was not set to perform all the time.

Step S20, judging whether the timer is overtime, if yes, executing step S30, and if no, executing step S20;

step S30, judging whether the WIFI data of the mobile terminal are internally and safely protected, if yes, executing a step S20, and if no, executing a step S40;

in this embodiment, how to determine whether the WIFI data is secure is specifically described as unsafe if there is a possibility that the data is rewritten by another person. For example, as shown in fig. 3, a WIFI data buffer is set to allow the other WIFI data of the mobile terminal to be written only when a preset value is written into the WIFI data buffer, otherwise, the value of the WIFI data of the mobile terminal cannot be written into, so that the data is prevented from being rewritten by others.

And S40, the WIFI data of the mobile terminal are easy to be subjected to security threat, and the values of all the WIFI data of the mobile terminal are retransmitted.

If the WIFI data of the mobile terminal is easy to be threatened by security, the data sent by the mobile terminal can be rewritten by other people and needs to be retransmitted.

The step S30 is configured with a mobile terminal WIFI data cache for local internal security protection of the WIFI data cache, and only when a preset value is written into the WIFI data cache, the other mobile terminal WIFI data are allowed to be written, otherwise, the value of the mobile terminal WIFI data cannot be written. As shown in fig. 3, the WIFI data of the mobile terminal is shown in the diagram, and only after writing the preset value into the WIFI data buffer (so that other people can be prevented from rewriting the WIFI data received and sent by the mobile terminal to achieve the purpose of security), other WIFI data of the mobile terminal that needs to be sent can be written, otherwise, other WIFI data of the mobile terminal that needs to be sent cannot be written, so that the mobile terminal cannot send data through WIFI.

In the step S30, the method determines whether the WIFI data of the mobile terminal is protected by local internal security, that is, reads the value of the WIFI data cache, if the value is not the preset value, it indicates that the WIFI data of the mobile terminal has used the local internal security, otherwise, it indicates that the WIFI data of the mobile terminal has not used the local internal security.

In a further embodiment, when the mobile terminal needs to send WIFI data, the following steps are performed:

step S50, suspending the timer started in the step S10, and then writing a preset value into the WIFI data cache;

step S60, writing in the value of WIFI data to be sent by the mobile terminal;

and step S70, after the writing is completed, writing values except the preset values into the WIFI data cache again to enable the values of the WIFI data of the other mobile terminals not to be written, and restarting the timer paused in the step S70.

In the step S70, after writing other mobile terminal WIFI data to be sent in the WIFI chip and writing a preset value into the WIFI data cache, the value is read and stored in the memory, and when detecting that the mobile terminal WIFI data is vulnerable to security threat in the step S40, the mobile terminal WIFI data value stored in advance is read from the memory and written into the mobile terminal WIFI data. The step of writing the WIFI data value of the mobile terminal is the same as steps S50 to S70.

The process of writing data in the WIFI data cache in the embodiment of the invention is as follows:

closing detection module

Writing 0xF2 into the WIFI data cache; through the step, the data writing operation can be performed on the WIFI data cache

writing any value (such as 0xAA, 0x66, 0x01, etc.) other than 0xF2 into the WIFI data cache; therefore, the WIFi data can be prevented from being written into the WIFI data cache by other people.

Restarting detection module

In addition, when the detection module is started, whether the WIFI data cache is written into 0xf2 or not can be detected regularly, and if yes, the existence of security threat is indicated.

Such as to send data 123456789 over WIFI

Shut down security detection

Writing WIFI data 123456789 of the mobile terminal;

Restarting security detection

In addition, when the security detection is started, whether the WIFI data cache is written into 0xf2 or not is detected at regular time, and if so, the existence of security threat is indicated.

Referring to fig. 4, fig. 4 is a functional block diagram of a mobile terminal according to a first preferred embodiment of the present invention, as shown in fig. 4, the mobile terminal of the present embodiment includes: WIFI chip 100, processor 200;

the WIFI chip 100, as shown in fig. 3, is internally provided with a mobile terminal WIFI data cache, where the WIFI data cache is used to increase the security of the mobile terminal WIFI data, specifically, only after writing a preset value into the WIFI data cache, other mobile terminal WIFI data that needs to be sent may be written, otherwise, other mobile terminal WIFI data that needs to be sent cannot be written, that is, the mobile terminal WIFI will not be able to send data. For convenience of the following description, the preset value is set to 0xF2 (the beginning of 0x represents hexadecimal, the following is the same meaning as 0xF 2).

With continued reference to fig. 4, the processor 200 includes a detection module 210, a WIFI data module 220, and a WIFI data backup module 230.

The detection module 210 is configured to detect whether the value before writing the WIFI data cache is a preset value (0 xF 2), and if so, indicate that the WIFI data of the mobile terminal may have a security threat. Because wifi data needs to be put into the sending buffer before sending, and the writing of the sending buffer needs to write 0xf2 into the sending buffer, if the writing of 0xf2 before the sending buffer is detected, the sending buffer is indicated to be illegal, and the data in the sending buffer may be illegally rewritten.

Of course, if someone else writes another value (not necessarily (0 xF 2) woolen), it is possible to be illegally rewritten; if someone else rewrites the WIFI data with a value such as 0xa1, then writing is not useful, because writing the WIFI data cache must first write 0xf2, and if not the WIFI data cache is not accessible, then writing must first write 0xf2.

Data transmitted according to the existing WIFI are also firstly put into a cache and then transmitted. For example, when the mobile phone is connected with the USB, other people can change the cached data, and then the data sent by the WIFI are changed by other people. The embodiment of the invention can prevent the overwriting, because the preset value is written into the WIFI data cache when the data is written before the WIFI data is transmitted, then the WIFI data to be transmitted is written into the WIFI data cache, and the preset value is modified to carry out the write-protection state.

The invention can resend the backup data even if the hacker rewrites the backup data, thereby ensuring the safety of the data. The WIFI data of the mobile terminal are easy to be threatened by security, and the values of all the WIFI data of the mobile terminal are retransmitted; and when the WIFI data has security threat, controlling to read the backup mobile terminal WIFI data value stored in the memory and writing the backup mobile terminal WIFI data value into the mobile terminal WIFI data.

That is, there is a wifi data cache in which data to be written must be written first with 0xf2. Then, when wifi sends data once again, the data to be sent needs to be written into the wifi data cache, and the step of writing the data includes:

closing the detection module;

writing 0xF2 into the WIFI data cache; through the step, the data writing operation can be performed on the WIFI data cache;

The detection module is restarted.

However, when the detection module reads that the value of the WIFI data cache before writing is 0xf2, the WIFI data cache is in a state that can be written, and then the WIFI data cache is illegally written, which means that the WIFI data may have security threat.

The method has the advantages that data sent by the WIFI are prevented from being illegally written by others, and the safety of the data sent by the WIFI is guaranteed.

The WIFI data module 220 is configured to configure WIFI data of the mobile terminal; the WIFI data module 2 configures the WIFI data of the mobile terminal, and comprises the following steps:

Step S220-1, closing the detection module 210;

step S220-2, writing 0xF2 into the WIFI data cache;

step S220-3, writing WIFI data of the mobile terminal; the mobile terminal WIFI data written in the method are mobile terminal WIFI data except for WIFI data cache;

step S220-4, writing any value (such as 0xAA, 0x66, 0x01, etc.) except 0xF2 into the WIFI data cache;

step S220-5, reading WIFI data of all the mobile terminals and storing the WIFI data in the WIFI data backup module 230; the WIFI data of the mobile terminal read here are the WIFI data of the mobile terminal except the WIFI data cache;

step S220-6, the detection module 210 is restarted.

The WIFI data backup module 230 is configured to backup the last written WIFI data of the mobile terminal, and is configured to resend the WIFI data when the detection module 210 detects that the WIFI data of the mobile terminal has a security threat.

According to the WIFI data internal security protection method for the mobile terminal based on the embodiment, the following steps are executed every second:

step S1, a detection module 210 detects whether the value of the WIFI data cache is 0xF2, if yes, the step S2 is executed by the mobile terminal WIFI data, if no, the step S1 is executed continuously after waiting for 1 second to arrive;

Step S2, the WIFI data module 220 rewrites the WIFI data value of the mobile terminal backed up by the WIFI data backup module 230; namely, the WIFI data value of the mobile terminal backed up by the WIFI data backup module 230 is retransmitted through steps S220-1 to S220-6.

The WIFI data protection processing method for the mobile terminal provided by the other preferred embodiment of the invention comprises the following steps:

when the WIFI data has security threat, controlling to read the backup mobile terminal WIFI data value stored before from the memory and writing the backup mobile terminal WIFI data value into the mobile terminal WIFI data; as described in detail above.
