Description

Technical Field

[0001] The embodiments of the present invention relate to the field of domain data analysis and processing, and in particular to a method, apparatus, device, and storage medium for generating an emoji-based password. Background Art

[0002] Relying on the development of the Internet, online communication between users is becoming more and more frequent. There is a lot of information sharing in online communication, such as simple information sharing, shopping link sharing, news sharing, etc., and also sharing invitation codes for adding friends or joining groups on social networks. The above information sharing is usually done by users generating a string of letters, numbers or special symbols randomly combined at the place where the information is generated, and then forwarding and sharing it. This string can become a password. Figure 1 As shown, a general flow chart of string generation in an existing social scenario is shown. The initial step receives a user password generation request; next, a string password is generated according to the parameters of the initial step, and then the user information corresponding to the string password is stored; finally, the generated string password is returned to the user.

[0003] However, this traditional string-based information sharing method has two drawbacks. First, from a security perspective, string-based information is easily recognized by other software, and then blocked or restricted by other software. Currently, most software generally has sharing restrictions and blocking mechanisms for information that is not from its own source, such as truncation, copy restriction, and sharing restriction, which results in user sharing failures, or other users who see it cannot copy it, resulting in sharing failures, affecting the effectiveness of information dissemination and sharing. Second, from a fun perspective, this string is just a piece of garbled code in the eyes of users, lacking fun and difficult to attract users' attention. Therefore, there is a need for an information sharing method that can break through the limitations of various software platforms while increasing fun.

[0004] Unicode, an international standard, began assigning code points to emoji in 2010. Now, as a special type of Unicode, emoji is supported by various operating systems and application software, providing a technical foundation for emoji-based information sharing. However, existing technologies use the same template to convert character strings to be shared into emojis regardless of the scenario, resulting in a certain regularity in the generated emojis and insufficient security for information sharing. Therefore, there is an urgent need for a highly secure method, device, equipment, and storage medium for generating emoji-based passwords. Summary of the Invention

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that in each embodiment of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and referenced to each other under the premise that there is no contradiction.

[0050] The first embodiment of the present invention relates to a method for generating a password based on emoji, such as Figure 1 As shown, the emoji-based password generation method specifically includes the following steps:

[0051] determining a first emoji candidate dataset based on the user's emoji usage history information, wherein each first emoji in the first emoji candidate dataset includes emoji category information;

[0052] Determining, from the first emoji candidate dataset, a second emoji dataset corresponding to each password mapping template based on the security level of each password mapping template, and establishing each password mapping template using the emojis in the second emoji dataset corresponding to each password mapping template to form a password mapping template set, wherein each password mapping template in the password mapping template set defines a mapping relationship between characters and emojis, each password mapping template having a different security level, and each password mapping template having a different number of emoji categories contained in the second emoji dataset corresponding to each password mapping template;

[0053] Calculating a security level of the password based on the password generation request, and matching a target template from the password mapping template set according to the password security level;

[0054] The string password is converted into an emoji password based on the target template.

[0055] The present invention provides an emoji-based password generation method that generates an emoji candidate dataset for defining a password mapping template based on historical emoji usage information. Password mapping templates of varying complexity are designed based on different security levels, thereby improving the security of emoji passwords from both the information source and the conversion rules. Specifically, emojis can be used not only for password generation but also for everyday social interactions and information expression. To prevent applications from identifying emoji passwords, it is necessary to obfuscate the purpose of user-provided emojis. Since users often enter and use emojis in everyday social interactions or information browsing, and to prevent information-sharing applications from identifying the currently entered emoji as a password for information sharing, the present invention determines the emojis in the password mapping template based on historical usage information. This means that the emojis entered by users in everyday social interactions are also used as passwords, using the same emojis for both purposes. This prevents applications from identifying emoji passwords and blocking or cracking them, thereby improving password security. On the other hand, the present invention provides password mapping templates with different security levels, which meet the requirements of password security in different scenarios and improve the security of emoji passwords.

[0056] After converting the string password into an emoji password based on the target template, the method further includes: copying and forwarding the emoji password; the password recipient copies the emoji password and enters the application corresponding to the emoji password; in response to the application corresponding to the emoji password detecting the copied emoji password, the application corresponding to the emoji password issues an operation request to the user who issued the emoji; the user who issued the emoji performs pre-authentication and post-authentication on the emoji password respectively, and if the pre-authentication and post-authentication pass, the preset operation is performed in response to the operation request; otherwise, the operation request is rejected. Wherein, the target template defines the mapping relationship between characters and emojis, and the password parsing template defines the mapping relationship between operations, intentions and strings. Preferably, if the emoji password is a password for inviting people to join a group in WeChat, the initiator is, for example, the group owner. After receiving the emoji password, the recipient copies the password and opens the application corresponding to the emoji password, such as the WeChat app. In response to the application corresponding to the emoji password receiving the copied emoji password, the application sends an operation request to the initiator. After the initiator verifies the emoji password, the recipient is allowed to join the corresponding group. The pre-authentication specifically includes: verifying whether the password content format meets the first preset requirement, and the first preset requirement at least includes: the password length meets the length threshold and whether the password format is legal; if the emoji password passes the pre-authentication, before performing the post-authentication, it also includes parsing the emoji password into the string password according to the target template, and converting the string password into password information and user information corresponding to the password information according to the password parsing template; the post-authentication specifically includes: detecting whether the password information corresponding to the emoji password meets the second preset requirement and detecting whether the user information corresponding to the password information meets the third preset requirement at the same time, the second preset requirement at least includes that the generation time of the password information is less than the first preset time difference from the current time, and the third preset requirement is that the user corresponding to the password information has not been banned.

[0057] Generally speaking, emojis include multiple categories, such as animals, fruits, vegetables, etc. Therefore, each emoji expression has a category attribute. The first emoji candidate data set is determined based on the user's emoji historical usage information, specifically including: counting the categories of emojis used in the first historical time period under the password requirement scenario, sorting the categories of each emoji according to the frequency of use, obtaining the top n categories as candidate categories, and obtaining emojis of each candidate category to form the first emoji candidate data set. The first emoji candidate data set contains multiple emojis, and each emoji contains a category attribute. Specifically, the historical usage data of various applications of users in the client are obtained, and the applications that use information sharing and their information sharing application scenarios are marked based on the historical usage data of various applications as password requirement scenarios.

[0058] It can be understood that the emoji-based password generation method provided by the present invention directly selects emojis by counting high-frequency emojis in password-required scenarios. In this way, on the one hand, emojis can be widely used in daily communication, and on the other hand, emojis of the same type as those used in daily communication can be widely used in password generation. Even if the application recognizes the emoji, it cannot distinguish whether daily communication and passwords are required, and thus cannot block, truncate, or perform other operations on the emoji-based passwords, thereby improving the success rate of cross-application password forwarding.

[0059] Before determining the second emoji data set corresponding to each password mapping template from the first emoji candidate data set according to the security level of each password mapping template, the method also includes: obtaining historical usage data of various applications of users in the client; marking the applications that use information sharing and their information sharing application scenarios based on the historical usage data of various applications to obtain a first scenario set, wherein the first scenario set includes multiple first scenario pairs, and each first scenario pair stores the applications that use information sharing and their corresponding information sharing application scenarios in a combined form; extracting the application identifier and the semantic vector of the information sharing application scenario in each first scenario pair in the first scenario set as input, and evaluating the security factor score of the first scenario pair with the help of the first model; according to the security factor score of each first scenario pair in the first scenario set, determining that there are k security level hierarchies, that is, including k password mapping templates with different security levels, and establishing k password mapping templates with different security levels according to the security level from high to low. Based on the number of security level levels, the number of required emoji types corresponding to each password mapping template is calculated, and based on the number of required emoji types, the second emoji data set corresponding to each password mapping template is determined from the first emoji candidate data set. The security levels of each password mapping template are different, and the number of emoji categories contained in the second emoji data set corresponding to each password mapping template is different. For example, the number of required emoji types corresponding to the password mapping template with a security level of i is P(i) = i*P(0), where P(0) is the number of basic required emoji types. Each password mapping template corresponds to a different security level, and each password mapping template corresponds to a security level, such as a high-security level for inviting people to join a group, or a low-security level for sharing Taobao links; the higher the security level, the more types of emojis it contains.

[0060] After determining the second emoji data set, each password mapping template is established using the emojis in the second emoji data set corresponding to each password mapping template to form a password mapping template set. Each password mapping template in the password mapping template set defines a mapping relationship between characters and emojis. Specifically, the characters in each password mapping template include uppercase letters, lowercase letters, numbers, and special symbols, and the mapping relationship between each type of character and emoji is defined respectively. Among them, one character type can correspond to one type of emoji. Furthermore, to improve the security of emoji passwords, one character type can correspond to multiple types of emoji.

[0061] Calculating a password security level based on a password generation request specifically includes: responding to a user's information sharing demand generated in a first application, extracting a first scenario semantic vector based on the location where the information sharing demand was generated, and issuing a password generation request, wherein the password generation request includes at least user information, a first application identifier, and a first scenario semantic vector. As an optional embodiment, if a first preset trigger word is detected during the use of the first application, the first application is triggered to generate an information sharing demand, and the first preset trigger word includes at least forwarding, sharing, etc. For example, if the first application is WeChat, during a WeChat chat, the user mentions "wait a moment, I'll forward it to you", the first preset trigger word is detected, the user's information sharing demand is identified, and the first application is triggered to generate an information sharing demand; further, as another optional embodiment, if the user clicks a preset button in the first application, the first application is triggered to generate an information sharing demand; as another optional embodiment, if the first preset trigger word is detected during the use of the first application, the context of the first preset trigger word in the first application is obtained, and the presence of an information sharing demand is identified based on the detected first preset trigger word and the context calibration of the first preset trigger word.

[0062] In response to detecting the password generation request, the first application identifier and the first scenario semantic vector of the password generation request are extracted and input into the first model to obtain a password security factor score; based on the password security factor score, the security level corresponding to the password mapping template is determined, and the target template is matched from the password mapping template set according to the security level.

[0063] The converting of the string password into emoji based on the target template specifically includes: obtaining user information based on the password generation request, determining the unique identifier of the string password generated in response to the password generation request; matching the same password in the historical password database based on the user information in the password generation request and the unique identifier of the string password; if so, verifying the validity of the same password in the historical password database; if so, converting the same password in the historical password database into emoji based on the target template; if not or the password is invalid, matching the target password parsing template based on the user information, generating a string password based on the target password parsing template, and converting the generated string password into an emoji password based on the target template. As an optional embodiment, the verifying the validity of the same password in the historical password database specifically includes: the password has a first timestamp for recording the time when the password was generated, calculating whether the time difference between the first timestamp of the same password in the historical password database and the current time is less than a time validity threshold; if so, the same password in the historical password database is valid; otherwise, it is invalid.

[0064] After converting the character string password into an emoji password based on the target template, the method further includes: associating and storing user information, a unique identifier of the character string password, and the character string password in a historical password database, and returning the emoji password to the requesting user.

[0065] As an optional embodiment, the emoji-based password generation method further includes: updating each password mapping template in the password mapping template set according to the security level of each password mapping template, and updating the validity of the emoji password based on the first timestamp of the emoji password. Specifically, an update period corresponding to each security level is set, and the update period of each password mapping template in the password mapping template set is determined according to the security level of each password mapping template. If the update period is reached since the password mapping template was generated, the method returns to the step of determining the second emoji data set corresponding to each password mapping template from the first emoji candidate data set according to the security level of each password mapping template. The time value of the generation of the emoji password is used as the first timestamp, and the validity period of each password is set according to the security factor score of the password. If the validity period is reached since the first timestamp, the corresponding emoji password is set to an invalid state.

[0066] As an optional embodiment, the emoji-based password generation method further includes: updating the first emoji candidate data set according to a preset data update cycle, wherein the length of the data update cycle is greater than the update cycle corresponding to each password mapping template and the validity period of each password.

[0067] A second embodiment of the present invention provides an emoji-based password generation device, wherein the emoji-based password generation device specifically includes:

[0068] a data collection module, configured to determine a first emoji candidate dataset based on historical emoji usage information of the user, wherein each first emoji in the first emoji candidate dataset includes emoji category information;

[0070] a template matching module, configured to calculate a security level of a password based on a password generation request, and match a target template from the password mapping template set according to the security level of the password;

[0071] A password conversion module is used to convert the string password into an emoji password based on the target template.

[0072] The emoji-based password generation device also includes: a sending module, which is used to copy and forward the emoji password after converting the string password into an emoji password based on the target template; the password recipient copies the emoji password and enters the application corresponding to the emoji password. In response to the application corresponding to the emoji password detecting the copied emoji password, the application corresponding to the emoji password issues an operation request to the user who issued the emoji; the user who issued the emoji performs pre-authentication and post-authentication on the emoji password respectively. If the pre-authentication and post-authentication are passed, the preset operation is performed in response to the operation request; otherwise, the operation request is rejected.

[0073] After converting the character string password into an emoji password based on the target template, the method further includes: associating and storing user information, a unique identifier of the character string password, and the character string password in a historical password database, and returning the emoji password to the requesting user.

[0074] As an optional embodiment, the emoji-based password generation device also includes: an update module, which is used to update each password mapping template in the password mapping template set according to the security level of each password mapping template, and update the validity of the emoji password based on the first timestamp of the emoji password; update the first emoji candidate data set according to a preset data update cycle, and the length of the data update cycle is greater than the update cycle corresponding to each password mapping template and the validity period of each password.
