In order to solve the above problems, embodiments of the present invention provide a text information protection method, apparatus, and system in a webpage. After the browser client sends the webpage request information to the server, the text in the webpage is mixed on the server side, that is, the order of the text arrangement in each piece of text is disordered, and the shuffling method is encrypted and mixed with the webpage to be transmitted to the webpage. Browser client. After the browser client receives the webpage, it performs normal parsing and layout. The text is also mixed in the internal storage of the browser. However, when the text is displayed, the text is back-mixed according to the shuffle rule given by the server. The text to be in the normal order. When a user copies a piece of text, the text stored from inside the browser is also shuffled.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other. First, the first embodiment of the present invention will be described with reference to the accompanying drawings. The embodiment of the invention provides a method for protecting text information in a webpage. The specific process is shown in FIG. 1 and includes:

Step 101: The information requested by the client for the combination request, in addition to the original content of the webpage request information, the information related to the encryption is also included in the webpage request information. For example, using the RSA algorithm as the encryption method, the client should generate a public key and combine the public key in the web page request information to send to the server.

Step 102: The client sends webpage request information to the server.

Step 103: The server receives webpage request information, where the webpage request includes normal request content and encryption related information (such as a public key) of the browser client.

Step 104: The server organizes the webpage data according to the content of the webpage request information.

Step 105: The server generates a shuffling algorithm, and the shuffling algorithm is a method of scrambling the text order.

2 is a shuffling algorithm used in the steps. It should be noted that the algorithm for the purpose of scrambling the text is within the scope of the present invention, which is not limited by the embodiment of the present invention.

The following describes the text shuffling process in conjunction with Figure 2:

Step 201: Take out a piece of text in the webpage, and the extracted text should be in a label. Step 202: Select a shuffling algorithm, and set the maximum sortable length of the shuffling algorithm to L. If the block text length is N, and N is greater than L, the text is divided into several segments (set to M segment), the length of the first M-1 segment is L, and the length of the last segment is less than or equal to L;

Step 203: Take out the first piece of text;

Step 204: Calculate the shuffling algorithm under the length according to the length of the extracted text, and Figure 3 lists a shuffling algorithm through the mapping relationship. The shuffle mapping relationship can be expressed as follows:

F(n) = m, l≤n, m≤ L me Z ne Z ^.^ F(n _l )≠ F(n ₂ ), n _x ≠ n ₂ where n is the position of a certain text in the original text block , m is the location of the text after the shuffle.

As shown in Figure 3, the text length is 13, and the maximum mix length is 8, you need to divide the text into two For the segment, the first segment has a length of 8, and the second segment has a length of 5.

The text 301 of the first paragraph is "I want to enter a piece of text", the length is 8, which is exactly the same as the maximum mixed length, and the mapping relationship is 303. After the shuffle, the text changes to "Segment I want to enter the text", as shown in 302.

The second paragraph of text is "row chaotic ordering", the length is 5, less than 8, first find out the length of 5 mixed mapping. As shown in FIG. 3, 304, F(3), F(4), F(7) are removed, and the sequence numbers are rearranged to obtain a mixed-length mapping relationship of length 5, as shown by 305. Through the shuffle mapping, you can get the shuffled text as "chaotic sorting mix".

Step 205: Perform mixing on the text according to the mixing algorithm;

If the text has not been taken, the text is removed and the process proceeds to step 204. Until all the text has been taken.

Step 106: Complete text mixing. When the text is mixed, the text is divided into blocks according to the label. For example, the following text, each p label is a piece of text, and a total of 3 pieces of text are mixed: " Although some reasonable requirements put forward by developing countries are not obtained. Satisfied, but the Chinese delegation stated that regardless of the progress of the negotiations, China will unswervingly follow the green and low-carbon development path.

According to the Chinese delegation, this conference made a final decision on the three major issues that all parties are concerned about - the Durban platform process, the compensation mechanism for loss damage, and the funding problem. The result.

The meeting was held on the 11th and was scheduled to close on the 22nd. However, due to the huge disputes between developed and developing countries on key issues such as the basic principles of climate change, compensation mechanisms for loss and damage, and funds, the conference had to continue. The consultation was postponed until the evening of the 23rd. ,,.

Step 107: Encrypt the shuffling algorithm, such as RSA encryption.

Step 108: Combine the mixed webpage data with the encrypted shuffling algorithm. Step 109: The server sends the webpage data and the encrypted shuffling algorithm to the client. Step 110: The client receives the webpage data sent by the server and the encrypted shuffling algorithm. Step 111: The client starts to parse the webpage data, and the parsed data has a DOM tree. In , the text is still mixed text.

Step 112: The client decrypts the shuffling algorithm. The anti-mixing algorithm is obtained by decrypting using the private key of RSA.

An example of an anti-mixing algorithm is shown in FIG. 4. It should be noted that the algorithm for restoring the mixed text to the original sequence can be used as the anti-mixing algorithm, which is not limited by the embodiment of the present invention.

The anti-mixing method shown in Figure 4 is as follows:

Step 401: Take a piece of text in the webpage, and the extracted text should be in the same webpage label; Step 402: If the text length is N, and N is greater than L (L is the maximum sortable length of the shuffling algorithm), then the text is divided into For several segments (set to M segment), the length of the first M-1 segment is L, and the length of the last segment is less than or equal to L;

Step 403: Take out the first piece of text;

Step 404: Calculate a mixed mapping relationship of the length according to the length of the extracted piece of text;

Step 405 calculates an inverse mapping relationship;

Step 406: Perform anti-mixing according to the reverse mapping relationship file, and restore the mixed text to the original text;

This step is specifically shown in Figure 5. The relationship between the anti-mixing mapping relationship and the shuffling mapping is an inverse function relationship, which is expressed as follows:

G(m) - F~ ^l (n), \ < m, n < L me ZZ

The text needs to be segmented during the anti-mixing process. As shown in the example in Figure 5, the character length is 13 and needs to be divided into two segments. The length of the first segment is 8, and the length of the second segment is 5.

The text of the first paragraph is "Paragraph my text wants to enter one", and the mixed mapping relationship obtained from the server is shown as 503 in Fig. 5, then the inverse mapping relationship can be obtained as shown in Fig. 5, 504.

Through the inverse mapping relationship, you can get the anti-mixing text as "I want to put a piece of text into".

The second paragraph of the text is "chaotic sorting mixed", the text length is 5, the mixing from the server If the mapping relationship (shown as 505 in Figure 5) is 8 in length, you need to extract the hybrid mapping relationship of length 5, as shown in 505 in Figure 5, and remove F(3), F(4), and F(7). Then, the sequence numbers are rearranged to obtain a mixed-length mapping relationship of length 5, as shown by 506 in Fig. 5, and the length-inverted-displacement mapping relationship (shown as 507 in Fig. 5) is calculated. Through the inverse mapping relationship, you can get the anti-mixing text as "line chaotic sorting".

If the text has not been completed, the next paragraph of text is taken to step 407, and the process proceeds to step 404. Until all the data is taken. Step 113: The client layouts the webpage, and renders the data storage in the browser layout (such as the web tree's Render tree). The Chinese text is also arranged in a mixed row, and the text is mixed and arranged according to the mixed sorting algorithm when the final text is displayed. . Because text is always in a mixed order in the browser client memory, users can only get mixed text when copying text on a web page.

Step 114: The client displays the webpage to the user. Embodiment 2 of the present invention will be described below with reference to the accompanying drawings.

An embodiment of the present invention provides a method for protecting text information in a webpage. The process for protecting text in a webpage by using the method is as shown in FIG. 6, and includes:

Step 601: The client generates a public key, and combines the public key with the webpage request information. Step 602: The client sends webpage request information to the server.

Step 603: The server receives the webpage request information of the client.

Step 604: The server mixes the text in the webpage requested by the client to obtain the mixed text.

In this step, the server mixes the original text, that is, disturbs the sorting of the text in the original text, and

Specifically, the following steps are included:

In this step, the hashing map may be used to divide the text block into M segments, and the length of the first M - 1 segment is the maximum row length of the shuffling algorithm, and the length of the last segment is less than or equal to the shuffling algorithm. The maximum sizable length, the length of each piece of text is less than the length of the text block. The text block is then hashed hierarchically according to the following expression:

Where n is the position of a certain text in the original text block, m is the position of the text after the shuffling, and L is the length of a piece of text.

605. The server sends, to the client, the webpage data requested by the client, and the text in the webpage that is mixed in the webpage data.

In this step, preferably, the server encrypts the shuffling algorithm by using the public key, combines the encrypted shuffling algorithm with the webpage data, and sends the webpage data to the client. .

Step 606: The client receives the webpage data returned by the server, and the webpage data carries the text in the webpage after the shuffling.

Step 607: The client stores the webpage data, and displays the text in the hashed webpage after being restored to normal;

This step specifically includes the following steps:

1. The client parses the webpage data, and stores the data obtained after parsing is completed in a DOM tree;

2. The client decrypts the shuffling algorithm by using a corresponding private key to obtain a backmixing 3. Layout the webpage, and store the text in the shuffled webpage in the browser memory;

4. When the text in the webpage is displayed, the text is back-mixed according to the anti-mixing algorithm, and the text in the webpage is restored to normal and displayed;

This step specifically includes:

a. The client extracts a text block in a label in the webpage;

Taking the shuffling algorithm in step 604 to complete the shuffling as an example, in this step, the anti-mixing is completed according to the following method:

Dividing the text block into M segments, the length of the first M - 1 segment is the maximum row length of the shuffling algorithm, and the length of the last segment is less than or equal to the maximum row length of the shuffle algorithm, each piece of text The length of the text block is less than the length of the text block, and the text block is back-mixed and mapped step by paragraph according to the following expression:
