Abstract

A method for preventing information from being stolen includes: pre-establishing a sensitive character database in a mobile terminal; monitoring screen recording content when a screen recording function is activated by the mobile terminal; determining whether a sensitive character in the sensitive character database appears in the screen recording content; and if yes, the screen recording function is paused or a screen recording result is displayed by a black screen. A storage device and a mobile terminal are also provided.

First claim

1 - 15 . (canceled)

16 . A method for preventing information from being stolen, comprising:
pre-establishing a sensitive character database in a mobile terminal; monitoring screen recording content when a screen recording function is activated by the mobile terminal; determining whether a sensitive character in the sensitive character database appears in the screen recording content; and in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying a screen recording result by a black screen.

17 . The method for preventing the information from being stolen of claim 16 , wherein the sensitive character comprises at least one of numerals, letters, and Chinese characters.

18 . The method for preventing the information from being stolen of claim 16 , wherein the step of monitoring the screen recording content when the screen recording function is activated by the mobile terminal comprises:
detecting, by a backend of the mobile terminal, whether the mobile terminal activates the screen recording function; and when it is detected that the mobile terminal activates the screen recording function, the screen recording content is monitored in real time.

19 . The method for preventing the information from being stolen of claim 16 , wherein the step of determining whether the sensitive character in the sensitive character database appears in the screen recording content and the step of in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying the screen recording result by the black screen comprise:
acquiring the screen recording content which is monitored; and comparing the screen recording content to the sensitive character in the sensitive character database; in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying the screen recording result by the black screen.

20 . The method for preventing the information from being stolen of claim 16 , wherein a warning is generated by the mobile terminal when the screen recording function is performed by an android debug bridge (ADB) command.

21 . The method for preventing the information from being stolen of claim 20 , wherein the step of generating the warning comprises:
popping up, by the mobile terminal, a dialogue box to generate the warning to remind the user that a backend of the mobile terminal performs the screen recording function, when the screen recording function is performed by the ADB command.

22 . A storage device, comprising instructions stored therein, wherein the instructions are loaded by a processor to execute:
pre-establishing a sensitive character database in a mobile terminal; monitoring screen recording content when a screen recording function is activated by the mobile terminal; determining whether a sensitive character in the sensitive character database appears in the screen recording content; and in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying a screen recording result by a black screen.

23 . The storage device of claim 22 , wherein the sensitive character comprises at least one of numerals, letters, and Chinese characters.

24 . The storage device of claim 22 , wherein the instructions are loaded by the processor to execute:
detecting, by a backend of the mobile terminal, whether the mobile terminal activates the screen recording function; and when it is detected that the mobile terminal activates the screen recording function, the screen recording content is monitored in real time.

25 . The storage device of claim 22 , wherein the instructions are loaded by the processor to execute:
acquiring the screen recording content which is monitored; and comparing the screen recording content to the sensitive character in the sensitive character database; and in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying the screen recording result by the black screen.

26 . The storage device of claim 22 , wherein the instructions are loaded by the processor to execute:
generating a warning when the screen recording function is performed by an android debug bridge (ADB) command.

27 . The storage device of claim 26 , wherein the instructions are loaded by the processor to execute:
popping up a dialogue box to generate the warning to remind the user that a backend of the mobile terminal performs the screen recording function, when the screen recording function is performed by the ADB command.

28 . A mobile terminal, comprising:
a processor configured to implement instructions; and a storage device comprising the instructions stored therein, wherein the instructions are loaded by the processor to execute steps of: pre-establishing a sensitive character database in the mobile terminal; monitoring screen recording content when a screen recording function is activated by the mobile terminal; determining whether a sensitive character in the sensitive character database appears in the screen recording content; and in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying a screen recording result by a black screen.

29 . The mobile terminal of claim 28 , wherein after the step of pausing the screen recording function or displaying the screen recording result by the black screen, the instructions are loaded by the processor to execute steps of:
continuing the screen recording function when a page not including the sensitive character is switched to.

30 . The mobile terminal of claim 28 , wherein the sensitive character comprises at least one of numerals, letters, and Chinese characters.

31 . The mobile terminal of claim 28 , wherein the step of monitoring the screen recording content when the screen recording function is activated by the mobile terminal comprises:
detecting, by a backend of the mobile terminal, whether the mobile terminal activates the screen recording function; and when it is detected that the mobile terminal activates the screen recording function, the screen recording content is monitored in real time.

32 . The mobile terminal of claim 28 , wherein the step of determining whether the sensitive character in the sensitive character database appears in the screen recording content and the step of in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying a screen recording result by a black screen comprise:
acquiring the screen recording content which is monitored; and comparing the screen recording content to the sensitive character in the sensitive character database; in response to the sensitive character appearing in the screen recording content, pausing the screen recording function or displaying the screen recording result by the black screen.

33 . The mobile terminal of claim 28 , wherein a warning is generated by the mobile terminal when the screen recording function is performed by an android debug bridge (ADB) command.

34 . The mobile terminal of claim 33 , wherein the step of generating the warning comprises:
popping up, by the mobile terminal, a dialogue box to generate the warning to remind the user that a backend of the mobile terminal performs the sc
