The following is a brief description of concepts related to embodiments of the present disclosure.

In order to improve the modification efficiency of a document needing to be encrypted, in the scheme provided by the disclosure, a modification rule may be preset, where the modification rule may include a modification type and a type parameter, so that when the document needing to be encrypted is modified, a modification information document corresponding to modification information corresponding to the document may be generated according to the modification rule, and the modification information document is used to store the modification information of the document. The modification of the information document can be recorded without substantially modifying the original document, so that the original document is not required to be repeatedly encrypted, and the modification efficiency of the document needing to be encrypted is effectively improved. And the safety of the modified information of the original document can be effectively ensured by encrypting the modified information document.
In the scheme provided by the disclosure, the original document can be modified and displayed according to the modification information document, so that the modified document can be directly viewed.
In addition, in the scheme provided by the present disclosure, the modified information document corresponding to the original document may be regenerated in a manner of superimposing or merging the modified information each time according to the displayed modified document, and the modified information of the original document may be saved by using the regenerated modified information document. Through the mode of superposition of the modification information, the modification of the document every time can be recorded, and the integrity of the modification information is ensured. And the number of the modified information can be reduced by combining the modified information, so that the modification efficiency of the original document is further improved.
In addition, in the scheme provided by the disclosure, the original document can be segmented, when the original document needs to be modified, the corresponding relation between each piece of modification information and the segment identifier can be recorded, and the original document can be encrypted in a segmented manner. In this way, the segments can be decrypted, displayed and modified, thereby further improving the modification efficiency of the document needing encryption.
Based on the above description, the embodiments of the present disclosure provide a document processing method, the flow of the steps of which may be shown in fig. 1, including:
step 101, acquiring and displaying a first document.
In this step, the document that needs to be modified and encrypted can be acquired for display, so that the document that needs to be modified can be determined according to the display.
And 102, generating a first modified information document according to the displayed first document.
In the present embodiment, the first modification information document may be generated from the displayed first document. The generated first modification information document may include therein first modification information. The first modification information may be understood as information corresponding to modification of the first document, which is determined according to a preset modification rule, and includes modification type information and type parameter information. The modification type information is used for describing a modification mode of the document, and the type parameter information is used for describing modification content corresponding to the corresponding modification type information.
In one possible implementation, the type of modification may include, but is not limited to, deleting text, adding text, replacing text, and modifying text color. Taking the example of modifying the text color, the corresponding type parameter can be, but is not limited to, represented as (M, N, L, C), which indicates that the color of L characters starting from the nth character of the mth paragraph is modified to C color.
In a possible implementation manner, the first modified information document is generated according to the displayed first document, which may be automatically generating a blank document according to the displayed first document, and receiving input information corresponding to the first document that needs to be modified to obtain the first modified information document.
In another possible implementation manner, the information corresponding to the modification that needs to be made to the first document is identified according to the modification made to the displayed first document, and the first modified information document may be automatically generated.
It should be noted that, in a possible implementation manner, the generated first modification information document may include information corresponding to the first document that needs to be modified, that is, the sequence identifier of each piece of modification information, so as to avoid a subsequent error result in the modification of the first document according to the first modification information document.
In addition, it should be noted that, in a possible implementation manner, the first document may correspond to at least one first modification information document, and each first modification information document may include at least one piece of first modification information.
Step 103, encrypting the first document to obtain a first encrypted document, and encrypting the first modification information document to obtain a second encrypted document.
In this step, the original document that needs to be modified and encrypted may be encrypted to obtain an encrypted document, and the modification information document corresponding to the original document may be encrypted to obtain an encrypted document. Namely, the original document and the modification information document corresponding to the original document are encrypted respectively.
In one possible implementation, in step 101, the first document may be obtained by decrypting a corresponding encrypted document. At this time, the encrypted document can be directly used as the first encrypted document without encrypting the first document again, so that the modification efficiency of the first document is effectively improved.
And 104, generating a third encrypted document corresponding to the first document according to the first encrypted document and the second encrypted document, and storing the third encrypted document.
In this step, an encrypted document including the first encrypted document and the second encrypted document may be generated and stored as an encrypted document corresponding to the original document. Therefore, the modified document of the original document can be obtained subsequently according to the encrypted document without substantially modifying the original document, and the modification efficiency of the original document is effectively improved.
Further, the present embodiment may further include the following steps:
and 105, decrypting the second encrypted document in the third encrypted document, determining the first modification information, and decrypting the first encrypted document in the third encrypted document to obtain the first document.
In this step, the first encrypted document and the second encrypted document may be decrypted respectively according to the third encrypted document, so as to obtain the first document, and determine first modification information corresponding to the first document.
And 106, modifying the first document according to the first modification information, and determining and displaying a second document corresponding to the first document.
In this step, the first document may be modified according to the determined first modification information corresponding to the first document, so that the modified document is determined and may be displayed, so as to facilitate viewing of the modified document.
In a possible implementation manner, the corresponding modification type may be determined according to modification type information (which may be understood as a modification type identifier, for example, a modification type sequence number) in the first modification information, and the corresponding type parameter may be determined according to type parameter information corresponding to the modification type information, so as to modify the first document and determine the second document.
Further, the present embodiment may further include the following steps:
step 107, generating a second modified information document according to the displayed second document.
In this step, a second modification information document may be generated from the displayed second document. The generated second modification information document may include therein second modification information. The second modification information may be obtained by superimposing or combining information corresponding to the first document that needs to be modified and information corresponding to the second document that needs to be modified.
It can be understood that, in a possible implementation manner, on the basis of the first modified information document, the second document may be modified as needed according to the displayed second document, information corresponding to the first document that needs to be modified and the second document that needs to be modified is superimposed, and the second modified information document is obtained by superimposing the information.
For example, in the first modified information document, a piece of modified type information is a deleted word, and the corresponding type parameter is (M, N, L, C), and the type parameter indicates deletion of L characters starting from the nth character of the mth paragraph. If it is determined that a new piece of modification type information is modified character color, the corresponding type parameter is (M, N, L, C), and the type parameter indicates that the color of L characters starting from the nth character of the mth paragraph is modified to C, then the second modification information document may include the two pieces of modification information. The generated second modification information document may further include the sequence identifier of the two pieces of modification information.
For another example, in the first modified information document, a piece of modified type information is a deleted word, the corresponding type parameter is (M, N, L), and the type parameter indicates that the L character at the nth character position of the mth paragraph is deleted. If it is determined that a new piece of modification type information is an added character, the corresponding type parameter is (M, N, L), and the type parameter indicates that an L character is added at the nth character position of the mth paragraph. Then, in the second modification information document, the above-mentioned two pieces of modification information may be included to ensure the integrity of the modification information for each modification. The generated second modification information document may further include the sequence identifier of the two pieces of modification information.
In another possible implementation manner, on the basis of the first modified information document, the second document may be modified as needed according to the displayed second document, information corresponding to the first document that needs to be modified and the second document that needs to be modified is merged, and the second modified information document is obtained in a manner of merging the information.
For example, in the first modified information document, a piece of modified type information is a deleted word, the corresponding type parameter is (M, N, L), and the type parameter indicates that L characters at the nth character position of the mth paragraph are deleted. If it is determined that a new piece of modification type information is an added character, the corresponding type parameter is (M, N, L), and the type parameter indicates that an L character is added at the nth character position of the mth paragraph. Then, the two pieces of modification information can be offset in the second modification information document, and the second modification information document does not need to include the two pieces of modification information, so that the number of the modification information is reduced, and the modification efficiency of the original document is further improved.
For another example, in the first modified information document, a piece of modified type information is a deleted word, the corresponding type parameter is (M, N, L), and the type parameter indicates that the L character at the nth character position of the mth paragraph is deleted. If it is determined that a new piece of modification type information is a deleted character, the corresponding type parameter is (M, N, L), and the type parameter indicates that an L character is deleted at the nth character position of the mth paragraph. Then, in the second modified information document, the two pieces of modified information may be merged into one piece, the second modified information document includes one piece of modified information, the modified type information is a delete word, and the corresponding type parameter is (M, N, 2L), so as to reduce the number of modified information and further improve the modification efficiency of the original document.
Of course, if two pieces of modification information cannot be offset or combined into one piece, two pieces of independent modification information are included in the second modification information document even in the combined manner. At this time, of course, the generated second modification information document may also include the sequence identifier of the modification information.
And step 108, encrypting the second modification information document to obtain a fourth encrypted document.
In this step, the second modification information document may be encrypted, and the encrypted document corresponding to the modification information of the original document may be obtained again.
And step 109, generating and storing a fifth encrypted document corresponding to the first document according to the first encrypted document and the fourth encrypted document.
In this step, the newly generated fourth encrypted document and the generated first encrypted document are used without re-encrypting the first document, so that the re-modified first document can be saved, and the modification efficiency of the encrypted document is effectively improved when the data volume of the first document is large.
Further, before step 102, the present embodiment may further include the following steps:
step 102', segmenting the first document according to the segmentation rule corresponding to the document type of the first document.
In this embodiment, the whole original document may be encrypted, or the original document may be encrypted in segments. If the document needs to be encrypted in a segmented manner, in this step, a corresponding segmentation rule can be determined according to the document type of the document, and the document is segmented according to the determined segmentation rule. Segmentation rules may include, but are not limited to, segmenting by paragraph, segmenting by page number, or separating segments by text and format, among others.
In this step, the first document may be segmented according to the document type of the first document and the corresponding segmentation rule.
If step 102' is performed, then in step 103, each segment of the first document may be encrypted separately to obtain a first encrypted document.
In step 102, the first modification information document may further include a segment identifier corresponding to each piece of first modification information, so that the modification information corresponding to each segment can be quickly found according to the segment identifier, and subsequently, decryption, display and modification can be performed on each segment, thereby further improving the modification efficiency of the document.
The way of decrypting, displaying and modifying again for a segment of a document is similar to the way of decrypting, displaying and modifying again for the whole document and is not described herein again.
It should be noted that, in a possible implementation manner, modification information corresponding to the same segment may be stored in a first modification information document, so that the display and modification of the segment may be implemented by decrypting the first modification information document, and the modification efficiency of the encrypted document is further improved.
In the scheme provided by the embodiment of the disclosure, the modification of the encrypted document can be realized by a method of adding the encrypted text segment, so that the modification efficiency of the encrypted document is effectively improved. In the additional ciphertext fragment, the obtained modification information can be stored in a superposition mode to ensure the integrity of the modification information, or the obtained modification information can be stored in a combination mode to reduce the number of the modification information and further improve the modification efficiency of the encrypted document. In addition, the encrypted document can be encrypted and stored in sections, and each section is decrypted, displayed and modified, so that the modification efficiency of the encrypted document is further improved.
