DETAILED DESCRIPTION

For clarity, of illustration of objectives, features and advantages of the present disclosure, the drawings combined with the detailed description illustrate the embodiments of the present disclosure hereinafter. It is noted that embodiments of the present disclosure and features of the embodiments can be combined, when there is no conflict.
FIG. 1 is a block diagram of an electronic device implementing a method for embedding user information in webpages in one embodiment of the present disclosure. Referring to FIG. 1 , an electronic device 1 includes, but is not limited to, a storage device 11 and at least one processor 12. The above-mentioned components may be connected through a communication bus 13 or directly connected.
The electronic device 1 may be a computer, a mobile phone, a tablet computer, a personal digital assistant (PDA), and other devices with application programs installed. Those skilled in the art can understand that FIG. 1 is only an example of the electronic device 1 and does not constitute a limitation on the electronic device 1. For example, the electronic device 1 may also include input and output devices, network access devices, buses, and so on.
Security of information in relation to an enterprise website is more and more necessary. The electronic device 1 can embed user information in a webpage. When the webpage is leaked, a user who leaks the webpage can be traced.
FIG. 2 is a flowchart of a method for embedding user information in webpages in one embodiment. The method may be applied in an electronic device (such as the electronic device 1 of FIG. 1 ). According to different requirements, the order of the steps in the flowchart may be changed, and some steps may be omitted.
In block S21, the electronic device obtains user information of a user who logs into a target website.
The target website can be an enterprise website.
The user information may include a user name and/or a user ID. The user information may include Chinese character, alphabetic character, and numeric string. For example, the user information is “
A1234567”.
In one embodiment, when the user logs into the target website, the electronic device obtains the user information input by the user.
In block S22, for additional security, the electronic device can encrypt the user information to obtain encrypted information.
A method of encrypting the user information to obtain the encrypted information may include: randomly generating a character string; and encrypting the user information using the character string.
In the process of encrypting the user information, the character string may be used as an encryption key, and a preset encryption algorithm may be used to encrypt the user information. The preset encryption algorithm can be selected according to user requirements. For example, the preset encryption algorithm may be Advanced Encryption Standard (AES) encryption algorithm or exclusive or (XOR) encryption algorithm.
In another embodiment, the user information may be left unencrypted.
In block S23, the electronic device converts the encrypted information into color values.
In another embodiment, the electronic device may convert the user information into color values.
In one embodiment, a method of converting the user information or the encrypted information into color values may include (1) to (5) described below.
(1) The electronic device determines a Chinese character, an alphabetic character, and a numeric string in the user information or the encrypted information.
(2) The electronic device converts the Chinese character (such as “
”) into a first RGB value according to a first conversion rule. The first RGB value includes a first red (R) value, a first green (G) value, and a first blue (B) value. A method of converting the Chinese character into a first RGB value according to a first conversion rule may include: converting the Chinese character into a decimal ASCII code; dividing the decimal ASCII code into three portions denoted as A1, B1, and C1 according to a first ratio; calculating the first R value, the first G value, and the first B value according to the three portions of A1, B1, and C1; and combining the first R value, the first G value, and the first B value to the first RGB value. The first R value can be 255/A1, the first G value can be 255/B1, and the first B value can be 255/C1. A RGB value is a color value of red (R), green (G), and blue (B) channels. It should be noted that when A1 is equal to 0, the first R value is 0, when B1 is equal to 0, the first G value is 0, and when C1 is equal to 0, the first B value is 0.
(3) The electronic device converts the alphabetic character (such as “A”) into a transparency value according to a second conversion rule. A method of converting the alphabetic character into a transparency value according to a second conversion rule may include: obtaining an ordinal number of the alphabetic character in an alphabet; calculating a ratio value according to the ordinal number and a preset scale factor; and setting the ratio value as the transparency value. It should be noted that the preset scale factor is equal to or more than 26. The smaller the transparency value, the more transparent a color, and the larger the transparency value, the more opaque the color.
(4) The electronic device converts the numeric string (such as “1234567”) into a second RGB value according to a third conversion rule. The second RGB value includes a second R value, a second G value, and a second B value. A method of converting the numeric string into a second RGB value according to a third conversion rule may include: dividing the numeric string into three portions denoted as A2, B2, and C2 according to a second ratio; calculating the second R value, the second G value, and the second B value according to the three portions of A2, B2, and C2; and combining the second R value, the second G value, and the second B value to the second RGB value. The second R value can be 255/A2, the second G value can be 255/B2, and the second B value can be 255/C2. It should be noted that when A2 is equal to 0, the second R value is 0, when B2 is equal to 0, the second G value is 0, and when C2 is equal to 0, the second B value is 0.
(5) The electronic device obtains the color values according to the first RGB value, the transparency value, and the second RGB value.
For example, the user information is “
A1234567”. A first character in the user information is a Chinese character “
”, and a decimal ASCII code obtained for “
” is “54992”. “54992” can be divided into three portions of 54, 99, and 2 according to the first ratio. The first R value is calculated to be 255/54=4.722. The first G value is calculated to be 255/99=2.576. The first B value is calculated to be 255/2=127.5. The first RGB value is (4.722, 2.576, 127.5). The first RGB value (4.722, 2.576, 127.5) denotes a color. A second character in the user information is an alphabetic character “A”, an ordinal number of “A” in the alphabet is 1, the preset scale factor is 26, and the transparency value is 1/26=0.038. The remaining characters in the user information are numeric string “1234567”, and “1234567” is divided into three groups of 123, 45, and 67 according to the second ratio. The second R value is calculated to be 255/123=2.073. The second G value is calculated to be 255/45=5.667. The second B value is calculated to be 255/67=3.806. The second RGB value is (2.073, 5.667, 3.806). The second RGB value (2.073, 5.667, 3.806) also denotes a color.
The method of converting the user information into color values according to conversion rules between color values and characters ensures that the R value, the G value, and the B value are all within the range of (0, 255).
In block S24, the electronic device embeds the color values in a target webpage of the target website.
The target webpage can be any webpage of the target website.
The user information can be retrieved and obtained according to the color values embedded in the target webpage.
In one embodiment, a method of embedding the color values in the target webpage may include: generating a graphic according to the color values; and embedding the graphic in the target webpage. The graphic can be generated according to user requirements. For example, the graphic can be a bar code. A location where the graphic is embedded can be set according to user requirements. For example, the graphic can be embedded at a lower right corner of the target webpage.
After embedding the graphic in the target webpage, the electronic device may further obtain the first RGB value, the transparency value, and the second RGB value according to the graphic. The electronic device obtains the Chinese character according to the first RGB value; obtains the alphabetic character according to the transparency value, and obtains the numeric string according to the second RGB value. The electronic device obtains the user information according to the Chinese character, the alphabetic character, and the numeric string. According to the user information, the user can be identified.
The graphic may include the color values. The electronic device may identify the color values according to the graphic, and obtain the first RGB value, the transparency value, and the second RGB value from the color values. The electronic device may calculate the decimal ASCII code (the decimal ASCII code may be 255/the first RGB value), and obtain the Chinese character according to the decimal ASCII code. The electronic device may calculate the ordinal number (the ordinal number may be 26*the transparency value), and obtain the alphabetic character according to the ordinal number. The electronic device may calculate the numeric string (the numeric string may be 255/the second RGB value). The electronic device can retrieve the user information according to the Chinese character, the alphabetic character, and the numeric string. A user information database may be searched to determine whether the data input by a user matches the retrieved user information.
In one example, the first RGB value, the transparency value, and the second RGB value are respectively (4.722, 2.576, 127.5), 0.038, and (2.073, 5.667, 3.806). (255/4.722, 255/2.576, 255/127.5) (i.e., (54, 99, 2)) is output as a calculation. Therefore, the decimal ASCII code is 54992, and the Chinese character “
” is obtained according to the decimal ASCII code of “54992”. The ordinal number is calculated as 26*0.038 (i.e., 1), and the alphabetic character “A” is obtained according to the ordinal number. (255/2.073, 255/5.667, 255/3.806) (i.e., (123, 45, 67)) is output, therefore, the numeric string is 1234567. According to the Chinese character, the alphabetic character, and the numeric string, the user information “
A1234567” is obtained.
In the present disclosure, user information is converted into color values, the color values are embedded in the target webpage. If the target webpage or information in the target webpage is leaked, the user information can be obtained from the target webpage. Therefore, the source of the leakage can be traced, the security of the target webpage is improved.
