Abstract

The embodiment of the invention discloses a text encryption method and device. The method comprises the following steps: after a user terminal receives a text file sent by a network side, conducing encryption on the text file by utilizing identification information of the user terminal or set part information in the identification information, and generating a unique encrypted image on the text file; converting the text file and the encrypted image into an image file to be outputted. Or, the method comprises the following steps: when the network side sends the text file to the user terminal, conducing encryption on the text file by utilizing the identification information of the user terminal or the set part information in the identification information, and generating the unique encrypted image on the text file; converting the text file and the encrypted image into a graphic file, and sending the graphic file to the user terminal. According to the embodiment, through the setting of a graphic password on the text file, the identity of an infringer can be accurately positioned.

Description

technical field [0001] The embodiments of the present invention relate to encryption technology, and in particular to a text encryption method and device. Background technique [0002] At present, in the existing text distribution system, the text information is mainly encrypted, and after being distributed to the user, the user decrypts the key to view the relevant text information. Alternatively, the text is directly graphically distributed to users on the network side. By making the text graphical, it prevents the user from directly copying the text file and eliminates the piracy of the text file. However, the existing text distribution system can only prevent piracy of text files. For graphical text files, browsing users can directly download graphical files and publish them on the Internet. That is to say, there is currently no effective means to supervise the phenomenon of piracy for graphically processed text files. Contents of the invention [0003] In order to ...
