Detailed Description
The present invention will be further described with reference to the following examples.
The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple modifications of the method of the present invention based on the concept of the present invention are within the scope of the claimed invention.
The embodiment of the invention provides an automatic text selection encryption system. The system mainly comprises: the system comprises a first identity authentication module, a second identity authentication module, a text information decryption module, an automatic sensitive word screening module, a text information encryption module and a manual decryption encryption module.
The encryption system utilizes the first identity verification module to realize primary encryption on an encrypted text, a sensitive word bank is arranged in the encryption system, after new text information is input, the system automatically screens sensitive words according to the text information, and whether the text is encrypted or not is automatically selected according to the screened content. When the existing text is modified, the system requires second identity authentication, automatically screens sensitive words for the modified text information, and automatically selects whether to encrypt the text again.
Specifically, referring to fig. 1, fig. 1 is a flowchart of a text auto-selection encryption system.
In the embodiment of the invention, the first identity verification password is firstly set before the automatic text selection encryption system is used, and then the automatic text selection encryption system is accessed by using the first identity verification module. The first identity password, the second identity password and the decryption text password can be set to be the same or different and can be set according to the needs of the user.
Specifically, after a first identity verification password is input and enters the text automatic selection encryption system, the text information can be newly established and the existing encrypted text information can be checked and modified by entering the operating system.
When the text information is newly established, a text system is directly opened for information input. The automatic selection encryption system is provided with a sensitive word stock, sensitive word information in the sensitive word stock is set by a user according to needs and can be changed at any time according to the needs of the user, and the number of the sensitive words in the sensitive word stock can be one or more, without limitation. When the text system records information, the system automatically starts the sensitive word automatic screening module, compares and screens the recorded information and the sensitive words in the sensitive word library, screens the sensitive words in the text information, automatically marks the file as a sensitive file, automatically starts the text information encryption module, and sets the text as an encrypted text, so that the normal encryption of the text is not influenced when the system is closed due to sudden external reasons, such as sudden power failure, careless system closing of a user and the like, in the text recording process. After the text information is input, clicking and storing, the encrypted text is automatically encrypted and stored. If the user does not want to encrypt the text containing the sensitive words, after the text is stored, the user can start the manual decryption module, input the previously set password and manually decrypt the encrypted text. When sensitive words are not screened in the entered text, the system cannot start a text encryption module for the text, and the text is directly stored after the text information is entered.
After entering the first identity authentication module, when the user checks the existing text information, the user only needs to input the preset password in the popped password input window. At this time, the user can only view the text and cannot modify the text. When a user needs to modify the existing text information, the user needs to click to modify the existing text information after opening and checking, at the moment, the system starts the second authentication module, pops up a second authentication password window, and can modify the text after inputting a second authentication password in the window. When the text is modified, the system starts the sensitive word automatic screening module to check whether the modified content contains the sensitive word or not, if the modified text does not contain the sensitive word, the system automatically releases the encryption setting of the text, and if the modified text contains the sensitive word, the system still keeps the encryption setting of the text.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
