Embodiment
In technical scheme of the present invention, creatively proposed to be converted to picture by the text message with user input, guarantee in the transmittance process of this information to ensure information security not by behavior monitorings such as text monitoring, filtrations.
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Fig. 1 is the process flow diagram of the method for anti-text filtering monitoring in the embodiment of the invention.The picture translation function is set in the input method instrument, and then as shown in Figure 1, this method comprises:
101, when receiving the text message of user's input, described input method instrument is saved in the text message of user's input in the internal memory;
102, when receiving user's output order, the picture translation function in the described input method instrument is converted to picture with the text message in the described internal memory, with the output of the picture after the conversion.
In this step, user's output order is generally " carriage return " key in actual applications.
In one embodiment of the invention, before the described reception user input text of step 101 information, further comprise: judge whether the user has started the picture translation function;
If start, then when receiving user's output order, the picture translation function in the described input method instrument is converted to picture with the text message in the described internal memory, with the output of the picture after the conversion;
If do not start, then when receiving user's output order, described input method instrument is directly exported the text message in the described internal memory.
As seen, in the present embodiment, if the user is not activated the picture translation function, then acquiescence is text output, need not text message is converted to picture, but directly exports text.This mode makes the user can independently select whether to enable the function that text changes picture.
Method shown in Figure 1 is converted to picture by the text message with user input, guarantees in the transmittance process of this information to ensure information security not by behavior monitorings such as text monitoring, filtrations.
In said method, can realize by the following method the text message in the internal memory is converted to picture: the picture translation function in the input method instrument is mapped as picture with the dot matrix of text message correspondence.
In order to prevent the filtration monitoring of some text identification software, can also after being converted to picture, text message carry out the scrambling operation to this picture, comprising:
