Method and device for preventing text filtering and monitoring

Abstract

The invention discloses a method and a device for preventing text filtering and monitoring. The method comprises the steps as follows: setting an image conversion function in an input method tool; when receiving text information input by a user, storing the text information into a memory by the input method tool; and when receiving an output instruction from the user, converting the text information in the memory into an image by the image conversion function in the input method tool, and outputting the converted image. According to the technical scheme, the text information input by the user is converted into the image, so that the information is guaranteed to be not subjected to behavior monitoring such as text monitoring, text filtering and the like in the transmission process and the information safety is guaranteed; and meanwhile, the content of the text information is presented on the image, so that a receiver can directly read and view the text information without processes of key exchange, decoding and the like.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for anti-text filtering and monitoring. Background technique [0002] In the prior art, the system converts the user's input into character output by receiving the user's input and querying the character-code mapping table. Since it is directly output as text, there is a security risk of being monitored and filtered by a third party during the input, transmission, and reception processes. [0003] In order to eliminate the above hidden dangers, the prior art proposes a text encryption method, which encodes the text information or isolates the transmission medium by a certain method, so that unauthorized visitors cannot obtain the information contained therein. However, this text encryption method has great defects: 1) the cost of isolating the transmission medium is too high; 2) the encrypted text needs to be exchanged in some form between the communication...

Problems solved by technology

Since it is directly output as text, there is a security risk of being monitored and filtered by a third party during input, transmission, and reception.

[0003] In order to eliminate the above hidden dangers, the existing technology proposes a text encryption method, which encodes the text information or isolates the transmission medium by a certain method, so that unauthorized visitors cannot obtain the information contained therein.

However, this text encryption method has great defects: 1) the cost of isolating the transmission medium is too high; 2) the encrypted text needs to be exchanged in some form between the communication parties to carry out the key; 2) the application of the text encryption is restricted It is very limited, and it cannot support this encryption function in many general occasions, and it cannot even be used, such as instant messaging software that does not support text confidentiality
