Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
A Uniform Resource Locator (URL) is a compact representation of the location and access method of a Resource available from the internet, and is the address of a standard Resource on the internet. In the process of transmitting based on the uniform resource locator, the server may obtain data included in the uniform resource locator. For example, the parameter string in the uniform resource locator may use a form of "key (key) ═ key value", and the server may acquire the parameter string passed in the uniform resource locator based on the form.
In order to ensure the security of the data contained in the uniform resource locator, the data is generally encoded by BASE64, and then the encoded data is used in the uniform resource locator. However, when the server receiving the url acquires the url obtained by the encoding method, it is easy to analyze an error and perform an error operation. Therefore, the use of such a coding scheme may result in reduced security of the receiving end receiving the uniform resource locator.
In order to explain the technical means of the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic diagram illustrating an implementation flow of a data encoding method provided in an embodiment of the present application, where the method may be applied to a terminal and is applicable to a situation where security of a receiving end that receives a uniform resource locator needs to be improved.
The terminal can be a mobile phone, a computer, a server and other terminals.
Specifically, the data encoding method may include the following steps S101 to S103.
Step S101, acquiring data to be encoded.
In the embodiment of the application, the terminal may interact with other terminals based on the uniform resource locator, for example, data may be transmitted to the server based on the uniform resource locator. The data to be coded is data that the terminal needs to transmit based on the uniform resource locator.
If the data to be coded is not coded, the uniform resource locator is generally displayed through a browser, so that a user can easily acquire the uncoded data to be coded through the browser in the transmission process, and the problem of data leakage is caused. In order to ensure the security of the data to be encoded, the terminal needs to encode the data to be encoded first and transmit the data by using the encoded data.
Step S102, obtaining the security character.
The security character is a character having a unique analysis result when being analyzed. That is, when the security character is parsed by the receiving end of the received url, the character in the url has only one parsing result.
In the embodiment of the present application, when data transmission is performed based on a uniform resource locator, after receiving the uniform resource locator, a receiving end may parse the uniform resource locator to obtain data to be decoded, which includes each part, and then decode each part of the data to be decoded to restore the data, so as to obtain actual data content transmitted by the terminal.
However, when the receiving side parses the character in the uniform resource locator, there is a possibility that the parsing may be performed erroneously.
In the conventional encoding method, the encoded data includes some reserved characters, such as "+", "/", "? "and the like. However, these reserved characters are not only used to represent their own corresponding symbols, but also have some functional meaning. For example, "/" is used not only to denote "/", but also to separate hosts and paths in a uniform resource locator; "? "is used not only for the representation"? ", and also to separate the path in the uniform resource locator from the query parameters. For "/", "? When the receiving end analyzes such characters, the receiving end may have a misinterpretation condition, and based on the analysis result of the misinterpretation, the receiving end may perform an operation that does not meet the user's intention. Moreover, when a hacker attacks a receiving end of the uniform resource locator, the hacker often attacks the receiving end by using the characters to cause the situation that the receiving end performs the misinterpretation.
Therefore, in the embodiment of the present application, the security characters can be obtained, and since the characters are only used for representing the characters corresponding to the characters, when the encoded data is encoded by using the security characters, the receiving end has a unique analysis result when analyzing the characters in the uniform resource locator, and a situation of mis-analysis cannot occur.
The acquisition mode of the security characters can be selected according to actual conditions.
In some embodiments of the present application, the terminal may obtain a security character set by a worker according to an actual situation of the receiving end.
In other embodiments of the present application, the terminal may also obtain, according to the RFC3986 protocol, a character that is specified in the RFC3986 protocol and is not escaped during data transmission based on a uniform resource locator; then, characters with a plurality of analysis results when being analyzed are removed from the characters which are not subjected to the escape, namely, characters with multiple meanings are removed, and the rest characters in the characters which are not subjected to the escape are used as safety characters.
And S103, coding the data to be coded according to the safety characters to obtain coded first target data.
In the embodiment of the application, each character in the data to be encoded may be sequentially encoded, and each character is represented by a security character, so as to obtain encoded first target data. I.e. the characters in the first target data all belong to the security characters. Then, the first target data can be used as part or all of the uniform resource locator to perform data transmission based on the uniform resource locator.
According to the embodiment of the application, the security character is obtained, the data to be coded is coded according to the security character, and the coded first target data is obtained, so that in the process of data transmission based on the uniform resource locator, the characters used in the uniform resource locator all belong to the security character, the situation that a receiving end receiving the uniform resource locator generates misanalysis in the process of analyzing the uniform resource locator is avoided, the situation that the receiving end executes non-security operation after misanalyzing the uniform resource locator can be prevented, meanwhile, the situation that a hacker attacks the non-security character can be avoided, and therefore the security of the receiving end of the uniform resource locator can be effectively improved when the data transmission is performed based on the uniform resource locator.
Moreover, the security characters can be characters which do not need to be subjected to escape in the data transmission process based on the uniform resource locator, so that the characters in the first target data can be prevented from being subjected to escape into hexadecimal data during transmission, and the readability of the first target data is improved.
In order to further improve readability, in some embodiments of the present application, the step S103 may further include the following steps S201 to S202.
In step S201, confusable characters in the security characters are obtained.
Wherein, the confusable character may refer to a character having similar shapes in the security character, such as "0" and "O", "I" and "1", etc. Or may refer to characters that are error prone when a user uses a uniform resource locator.
In some embodiments of the present application, the obtaining manner of the confusable character may be selected according to actual situations. For example, the setting may be made by the user according to the actual situation. Or the terminal analyzes each character, detects whether a character group with the similarity larger than a preset similarity threshold exists in the security characters, and takes the characters in the character group with the similarity larger than the preset similarity threshold as the confusable characters. The setting can also be made according to the situation when the user actually uses the uniform resource locator.
Specifically, in some embodiments of the present application, as shown in fig. 3, the obtaining of the confusable character may include: the following steps S301 to S303.
Step S301, obtaining uniform resource locator sample data.
The uniform resource locator sample data refers to a pre-encoded uniform resource locator.
Step S302, input data corresponding to the uniform resource locator sample data input in the uniform resource locator input box is obtained.
The url input box may be an input box in a browser.
In some embodiments of the present application, a user may perform an input operation in the url input box according to url sample data to input the url. The terminal can acquire input data corresponding to the uniform resource locator sample data in the uniform resource locator input box based on the browser and analyze the input data.
Step S303, comparing each sample character in the uniform resource locator sample data with the corresponding input character in the input data, and taking the sample character in the uniform resource locator sample data different from the corresponding input character in the input data as the confusable character.
Specifically, each sample of the input data in the url input box may be sequentially compared with the corresponding input character in the url sample data to determine a sample character in the url sample data that is different from the corresponding input character in the input data, and the sample character that is different from the corresponding input character in the input data is used as the confusable character.
In some embodiments of the present application, the terminal may further calculate error data of each character based on a plurality of sets of input data and corresponding url sample data, and determine an confusable character based on the error data. For example, the number of times of errors of each character occurring in the sets of input data may be calculated, and characters having the number of times of errors larger than a preset number threshold may be regarded as confusable characters. Or, the error rate of the error of each character in the multiple sets of input data can be calculated, and the character with the error rate larger than the preset error rate threshold value is taken as the confusable character.
Step S202, according to the confusable character and the safe character, encoding data to be encoded to obtain first target data.
In some embodiments of the present application, each character in the first target data is a target character that belongs to a safe character and does not belong to a confusable character. Specifically, the confusable characters can be removed from the security characters, and the security characters from which the confusable characters are removed are used for encoding the data to be encoded, that is, the target characters are used for encoding the data to be encoded to obtain the first target data.
Specifically, in some embodiments of the present application, as shown in fig. 4, the step S202 may include the following steps S401 to S402.
Step S401, determining a coding mapping relation according to the safety characters and the confusable characters.
The code mapping relation is used for mapping each preset character into different target characters respectively. The target characters belong to safe characters, and all the target characters do not belong to confusable characters.
The form of the obtained coding mapping relation may be selected according to actual situations, and may be presented in a table manner, for example.
Step S402, coding the data to be coded according to the coding mapping relation to obtain first target data.
In some embodiments of the present application, according to the encoding mapping relationship, the data to be encoded may be encoded to use the target character to represent each character in the data to be encoded, so as to obtain the encoded first target data.
The specific encoding mode can be selected according to the form of the preset characters.
In some embodiments of the present application, the predetermined character may be a numeric character with a predetermined carry system. The total number of the digital characters is the same as the corresponding carry number of the preset carry system. For example, if the predetermined carry system is sixty-seven system, the numeric characters of the predetermined carry system are "0" to "66".
As shown in fig. 5, the above step S402 may include the following steps S501 to S502.
Step S501, the data to be coded is converted into intermediate data coded by digital characters.
Specifically, in some embodiments of the present application, data to be encoded may be first converted into data in a preset carry system, and the data in the preset carry system may be used as intermediate data. Since the total number of the numeric characters is the same as the number corresponding to the preset carry system, each character in the intermediate data may be represented by one of the numeric characters.
It should be noted that the total number of numeric characters can be determined according to the total number of security characters and the total number of confusing characters. Specifically, the total number of numeric characters may be less than or equal to the total number of security characters after the confusable characters are removed.
Step S502, according to the coding mapping relation, mapping each character in the intermediate data into a target character in sequence to obtain first target data.
In some embodiments of the present application, since each character in the intermediate data may be represented by a character in the numeric characters, the terminal may sequentially map each character in the intermediate data to a target character according to the coding mapping relationship.
Taking the total number of the digital characters as 67 as an example for explanation, that is, the preset carry system is sixty-seven system, the terminal may convert the data to be encoded into the first intermediate data in binary form first. And then converting the first intermediate data in the binary form into second intermediate data in a large integer format so as to splice all binary characters in the first intermediate data. Then, the second intermediate data is converted into sixty-seven system third intermediate data by a rolling phase division method. Finally, based on the coding mapping relationship, each character in the third intermediate data can be mapped into a target character in sequence to obtain first target data.
The above only describes the implementation manner of specific coding, and in practical applications, different conversion manners may be provided based on different preset carry systems, which is not described in detail herein.
It should be noted that, because the conventional BASE64 encoding method needs to convert data into sixty-four system numbers and encode the converted data into corresponding characters, the character string obtained by encoding has a large character quantity. In order to reduce the character quantity of the encoded character string, the carry number corresponding to the preset carry system may be greater than 64, that is, the total number of the numeric characters is greater than 64, and the character quantity of the encoded character string may be smaller than the character quantity of the character string encoded by the BASE64 encoding method.
According to the implementation mode of the application, the to-be-coded data are coded according to the confusable characters and the safe characters to obtain the first target data, so that in the data transmission process based on the uniform resource locators, the characters used in the uniform resource locators all belong to the safe characters and do not belong to the confusable characters, the readability of the first target data is improved while the safety of a receiving end is guaranteed, and after the uniform resource locators are obtained according to the first target data, the situation of input errors is not prone to occurring when a user inputs the uniform resource locators.
In some embodiments of the present application, different confusable characters may be selected for different users according to actual situations.
Specifically, each url input box may be bound with user information, which may be information used for uniquely identifying a user, such as a user identifier and user face information. Based on the uniform resource locator input box bound with different user information, confusable characters respectively associated with each user information can be respectively determined. Before encoding the data to be encoded, user information of a receiving end receiving the uniform resource locator can be obtained, and the data to be encoded is encoded based on the security character and the confusable character associated with the user information to obtain first target data. In this case, each user may have its own suitable encoding scheme.
Due to the fact that the visual perception abilities of different users and the using habits of the users are different, different characters which are easy to confuse can be removed from the different users in the method, the data obtained after coding can meet the personalized needs of the users, and the readability of the first target data is further improved.
Correspondingly, fig. 6 shows a schematic flow chart of an implementation of a data decoding method provided in the embodiment of the present application, where the method corresponds to the data encoding method shown in fig. 1, and can be applied to a terminal and can be applied to a situation where security of a receiving end that receives a uniform resource locator needs to be improved.
The terminal can be a mobile phone, a computer, a server, or the like, and can be a receiving end for receiving the uniform resource locator.
Specifically, the data decoding method may include the following steps S601 to S603.
Step S601, acquiring data to be decoded.
Step S602, a decoding mapping relationship corresponding to the coding mapping relationship is obtained.
Wherein, the coding mapping relation is a mapping relation determined according to the security characters. The security character is a character having a unique analysis result when analyzed.
Step S603, decoding the data to be decoded according to the decoding mapping relationship to obtain decoded second target data.
In an embodiment of the present application, a sending end of a uniform resource locator may encode data to be encoded based on the methods in fig. 1 to fig. 5 to obtain first target data, and then transmit the first target data based on the uniform resource locator. After the terminal receiving the uniform resource locator acquires the first target data (i.e., the data to be decoded), the terminal may decode the data to be decoded based on a decoding mapping relationship corresponding to the encoding mapping relationship used by the sending end to obtain decoded second target data, where the decoded second target data is the same as the data to be encoded, so that the terminal may acquire actual data content of the data transmitted in the uniform resource locator.
In some embodiments of the present application, the encoding mapping relationship is a mapping relationship determined according to a security character and an confusing character.
Moreover, a specific implementation manner of data decoding is a decoding manner corresponding to the encoding manner described in fig. 1 to fig. 5, which is not described in detail herein.
Taking the total number of the numeric characters in the coding mapping relationship as 67 for example, the terminal may obtain sixty-seven system fourth intermediate data according to a preset decoding mapping relationship, convert the sixty-seven system fourth intermediate data into binary fifth intermediate data, and convert the binary fifth intermediate data into second target data.
