Description

[0001] This invention patent application is a divisional application of the Chinese invention patent application with the application date of September 26, 2019, application number 201910914799.8, and name “Method and device for processing encryption behavior”. Technical Field

[0002] This document relates to the field of data processing technology, and in particular to a method and device for processing encryption behavior. Background Art

[0003] When using an app, users often need to change or retrieve their forgotten passwords. Due to the large number of people who need to retrieve their passwords every day, manual service resources are limited and service efficiency is low. Therefore, most people currently use self-service verification methods (such as SMS verification, facial verification, fingerprint verification, etc.) to retrieve their passwords. According to current data statistics, self-service verification methods have a high pass rate and good interaction. However, a large number of users are still unable to complete password changes through self-service verification every day, which hinders their business and financial needs and reduces their stickiness with the app over time. In addition, these users have a much worse user experience than those who successfully retrieve their passwords. Summary of the Invention

[0034] One or more embodiments of this specification provide a method and apparatus for processing a password modification behavior, so as to achieve personalized service for users and improve service efficiency when password modification fails.

[0035] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this document.

[0036] Figure 1 This is a schematic flow chart of a method for processing a password modification behavior according to an embodiment of this specification. Figure 1 As shown, the method includes:

[0037] S102, when the password change for the application fails, collect the user's password change behavior information; the password change behavior information includes at least one of the identity authentication behavior information during the password change process, the device information performing the password change behavior, the feedback information on the application within a preset time period, and the account information.

[0038] S104, determining the user's password-changing characteristic information based on the password-changing behavior information; the password-changing characteristic information includes at least one of the following: password-changing urgency, behavior risk level, sense of security loss, and account value.

[0039] S106, analyzing the encryption feature information, and determining the encryption service mode for the user according to the analysis result.

[0040] S108: Execute corresponding encryption service for the user according to the encryption service mode.

[0041] In this embodiment, different user password-changing behavior information corresponds to different password-changing feature information. For example, if the password-changing behavior information includes identity verification behavior information, the password-changing feature information may include the user's sense of security; if the password-changing behavior information includes account information, the password-changing feature information may include the user's account value; if the password-changing behavior information includes device information, the password-changing feature information may include the user's behavioral risk level; if the password-changing behavior information includes user feedback on applications within a preset time period, the password-changing feature information may include the user's password-changing urgency; and so on. Different password-changing service methods are provided for different password-changing feature information, thereby realizing zoned services (i.e., personalized services) for password-changing users.

[0042] One or more embodiments of this specification provide a method for processing password-changing behavior, which can be applied to subsequent service scenarios for users who fail to change their passwords. For example, after a user changes the password of an application and fails to change the password (such as due to authentication failure or forgetting the old password), the password-changing behavior information of the user is collected and the password-changing feature information of the user is determined, and then the password-changing service corresponding to the password-changing feature information is performed on the user. It can be seen that this technical solution fills the gap in the post-service of the full-link service of the current password-changing scenario.

[0043] Therefore, by adopting the technical solution of an embodiment of the present specification, when the password change fails, the password change service method for the user can be determined in a targeted manner according to the user's password change feature information (such as the urgency of password change, the degree of behavioral risk, the degree of lack of security, the account value, etc.), and then the corresponding password change service is performed on the user according to the determined password change service method, so that the post-service for the user who failed to change the password is more personalized, flexible and efficient, and can cover more users who failed to change the password, thereby improving the security service experience of the users who failed to change the password and increasing the user's stickiness to the application.

[0044] In one embodiment, the password-changing behavior information includes identity authentication behavior information and / or device information; the password-changing characteristic information includes the degree of behavior risk. Based on this, the user's password-changing characteristic information can be determined by any one or more of the following methods:

[0045] 1. Determine the user's behavioral risk level based on the user's identity verification behavior information during the password change process.

[0046] First, obtain the behavioral characteristics of high-risk accounts collected in advance; second, compare the user's identity authentication behavior information during the password change process with the behavioral characteristics of the high-risk account to determine the matching degree between the user's identity authentication behavior information during the password change process and the behavioral characteristics of the high-risk account; third, determine the user's behavioral risk level based on the matching degree; the matching degree is positively correlated with the behavioral risk level.

[0047] That is, the higher the matching degree between the user's identity authentication behavior information during the password change process and the behavioral characteristics of high-risk accounts, the higher the user's behavioral risk level, that is, the riskier the current password change behavior is; conversely, the lower the matching degree between the user's identity authentication behavior information during the password change process and the behavioral characteristics of high-risk accounts, the lower the user's behavioral risk level, that is, the safer the current password change behavior is.

[0048] High-risk accounts can be accounts with risky behaviors that have been pre-identified by the risk identification system and stored on the network side. The specific identification method is not limited in this embodiment. For example, if a high-risk account is a stolen account, the account can be determined to be a stolen account by the corresponding tags such as "stolen" or "lost". The behavioral characteristics of the stolen account can include information modifications (such as password changes, identity information modifications, etc.), information binding, information unbinding, account locking, etc. performed by the hacker on the stolen account.

[0049] The degree of match between the user's identity verification behavior during the password change process and the behavioral characteristics of high-risk accounts can be determined by calculating the distance between the feature vector corresponding to the identity verification behavior information and the behavioral feature vector of the high-risk account. The distance between feature vectors can be calculated using any existing method, such as Euclidean distance, Mahalanobis distance, normalized Euclidean distance, cosine distance, etc. Specific vector distance calculation methods are known in the art and will not be further described here.

[0050] 2. Determine the risk level of the user's behavior based on the device information used to perform the password modification behavior.

[0051] First, determine whether the device performing the password modification is a risky device based on device information. Second, determine the risk level of the behavior based on the judgment result. Device information may include the device's Internet Protocol (IP) address, hardware address, geographic location, etc.

[0052] Risky device information (such as IP address, hardware address, and geographic location) can be pre-stored on the network side. By comparing the corresponding information of the current device with that of risky devices, it can be determined whether the device is a risky device. The greater the probability that the device performing the password modification is a risky device, the higher the risk level of the user's behavior.

[0053] In this embodiment, by determining the risk level of the user's behavior, and then performing a password modification service corresponding to the risk level of the user's behavior, the post-service for the user who failed to modify the password can be based on the risk level after the modification, thereby reducing the success rate of password modification in risky situations to a certain extent.

[0054] In one embodiment, the password-changing behavior information includes identity verification behavior information; the password-changing characteristic information includes the password-changing urgency. Based on this, when determining the user's password-changing characteristic information based on the password-changing behavior information, the request event corresponding to the password-changing behavior can be first determined based on the identity verification behavior information; then, based on the preset correspondence between each request event and the password-changing urgency, the password-changing urgency corresponding to the request event can be determined.

[0055] The appeal event includes the reason for changing the password, the purpose of the change, and pending events after the change. Reasons for changing the password include losing the phone, forgetting the password, and changing the password multiple times without a regular pattern. Purposes for changing the password include changing the password of the bank card bound to the phone or resetting a new password. Pending events after the password change include logging into an account, transferring money, and business verification.

[0056] To meet the user's password change needs and combine them with the demands for emergency events in actual application scenarios, the urgency of password change can be set to be higher after the phone is lost, the second highest urgency after the password is forgotten, the lowest urgency for changing the password frequently and irregularly, and so on. Of course, this is just an example of the correspondence between one demand event and the urgency of password change. In addition, the urgency of password change corresponding to each demand event can be arbitrarily set according to needs.

[0057] In this embodiment, the corresponding password modification service is performed on the user according to the user's password modification urgency, so that the password modification service can better meet the user's current demands and urgency, thereby largely meeting the user's current needs and improving the user's password modification experience.

[0058] In one embodiment, the decryption behavior information includes user feedback on the application within a preset time period; the decryption characteristic information includes a sense of insecurity. Based on this, when determining the user's decryption characteristic information based on the decryption behavior information, the user's feedback on the application within the preset time period can be first analyzed to determine the user's experience with the application; then, based on the user's experience with the application, the user's sense of insecurity can be determined. The user's experience with the application is negatively correlated with the sense of insecurity; the feedback information includes voice feedback and / or text feedback.

[0059] That is, the higher the user's experience with the application, the lower his or her lack of security; conversely, the lower the user's experience with the application, the higher his or her lack of security.

[0060] In this embodiment, the user's experience with the application can, to a certain extent, reflect the user's stickiness to the application. The higher the stickiness, the less likely the user is to churn, while the lower the stickiness, the more likely the user is to churn. Therefore, based on the user's experience with the application, it is possible to accurately determine the user's lack of sense of security and thus accurately provide the user with a password-changing service that suits their needs.

[0061] In one embodiment, the password-changing behavior information includes account information; the password-changing characteristic information includes account value. Based on this, when determining the user's password-changing characteristic information based on the password-changing behavior information, the account value can be determined based on the account information. The account information may include account level, account balance, and account transaction amount. There is a positive correlation between account level and account value; there is a positive correlation between account balance and account value; and there is a positive correlation between account transaction amount and account value.

[0062] For example, account levels include Gold Card Account, Silver Card Account, and Ordinary Account. The account level of a Gold Card Account is higher than that of a Silver Card Account, which in turn is higher than that of an Ordinary Account. Therefore, the account value of a Gold Card Account is higher than that of a Silver Card Account, which in turn is higher than that of an Ordinary Account.

[0063] For another example, if the account balance of user A is greater than the account balance of user B, then the account value of user A is higher than the account value of user B.

[0064] For another example, the account transaction amount is the total transaction amount in the most recent month. Assuming that the total transaction amount of user C in the most recent month is greater than the total transaction amount of user D in the most recent month, the account value of user C is higher than that of user D.

[0065] In this embodiment, the corresponding password modification service is performed on the user according to the user's account value, so that the password modification service can be more in line with the level of the user's account value. Since users with higher account values ​​are more important to application merchants, while improving the user's password modification experience, it can also ensure the high value of application users.

[0066] The above details how to determine the user's password-changing feature information based on the user's password-changing behavior information. The following details how to determine the password-changing method for the user by analyzing the password-changing feature information.

[0067] In one embodiment, the password modification service mode for a user may be determined according to the following steps:

[0068] Step A1: Determine whether the user's behavior risk level is higher than a first preset threshold.

[0069] Step A2: If the user's behavior risk level is higher than the first preset threshold, the password-changing service mode for the user is determined to be the first type of service mode; if the user's behavior risk level is lower than or equal to the first preset threshold, it is further determined whether the user's password-changing urgency is higher than the second preset threshold.

[0070] Step A3: If the user's urgency for changing the password is lower than or equal to the second preset threshold, the password change service mode for the user is determined to be the second type of service mode; if the user's urgency for changing the password is higher than the second preset threshold, it is further determined whether the user's lack of sense of security is higher than the third preset threshold.

[0071] Step A4: If the user's lack of security is higher than the third preset threshold, the password-changing service method for the user is determined to be the third type of service method; if the user's lack of security is lower than or equal to the third preset threshold, the password-changing service method is further determined based on the corresponding relationship between the user's account value and the password-changing service method.

[0072] When executing step A4, each account value may correspond to a different score. If the score corresponding to the account value is lower than the first preset score, the password-changing service mode may be determined to be the second type of service mode; if the score corresponding to the account value is higher than the second preset score, the password-changing service mode may be determined to be the third type of service mode; if the score corresponding to the account value is between the first preset score and the second preset score, the password-changing service mode may be determined to be the fourth type of service mode; wherein the second preset score is higher than the first preset score.

[0073] In this embodiment, the service level of the third type of service mode is higher than the service level of the second type of service mode; the service level of the second type of service mode is higher than the service level of the first type of service mode; the service level of the fourth type of service mode is higher than the service level of the second type of service mode, and lower than the service level of the third type of service mode.

[0074] The higher the service level, the more complex the service method, and the more manual intervention required from the service provider. Conversely, the lower the service level, the simpler the service method, and the lower the manual intervention required from the service provider, and even services that require no manual intervention or no intervention at all. For example, as can be seen from the above, the first type of service method has the lowest service level, which can be a completely non-intervention service method; the second type of service method has a higher service level than the first type of service method, and can be a text message reminder service method, such as a text message reminding the user to use other password change methods or guiding the user step by step to complete the password change through text messages; the fourth type of service method has a higher service level than the second type of service method, and can be a verification information push service method, such as pushing user information for verification so that the user can complete the password change with one-click confirmation; the third type of service method has the highest service level, and can be an active phone call method. The active phone call method refers to a method of contacting the user through a manual customer service phone to provide one-on-one service.

[0075] In this embodiment, different encryption service methods are adopted for users who failed to change their password and users with different encryption feature information, so that the post-service for users who failed to change their password is more personalized, flexible and efficient, and can cover more users who failed to change their password, thereby improving the security service experience of users who failed to change their password and increasing user stickiness to the application.

[0076] Figure 2 This is a schematic flow chart of a method for processing a password change behavior according to a specific embodiment of this specification. In this specific embodiment, the user changes the password of application A. When the password change fails, the corresponding post-password change service is executed for the user. Figure 2 As shown, the method includes:

[0077] S201, collecting the user's password-changing behavior information.

[0078] The password change behavior information includes identity authentication behavior information during the password change process, device information for performing the password change behavior, feedback information on application A within a preset time period, and account information.

[0079] Authentication behavior information may include authentication methods (such as biometric identification, personal information verification, verification code input, etc.), identity information used for verification (such as fingerprints, irises, and other biometric features; or ID number, etc.). Device information may include the device's IP address, hardware address, geographic location information, etc. Feedback on Application A within a preset time period may include text feedback and / or voice feedback. For example, if a user uses Application A to execute an event and then comments on Application A regarding the execution results of that event, the comment may serve as user feedback on Application A. Account information may include account level, account balance, account transaction amount, etc.

[0080] S202, determining the user's password-changing characteristic information based on the user's password-changing behavior information, wherein the password-changing characteristic information includes the urgency of password-changing, the degree of behavior risk, the degree of lack of security, and the account value.

[0081] How to determine the user's password-changing feature information based on the user's password-changing behavior information has been described in detail in the above embodiments and will not be repeated here.

[0082] S203, determine whether the user's behavior risk level is higher than a first preset threshold; if not, execute S204; if so, execute S207.

[0083] S204, determining whether the user's password change urgency is higher than a second preset threshold; if so, executing S205; if not, executing S208.

[0084] S205: Determine whether the user's lack of sense of security is higher than a third preset threshold. If not, execute S206; if so, execute S209.

[0085] S206: Determine the password-changing service mode for the user based on the corresponding relationship between the user's account value and the password-changing service mode.

[0086] Specifically, assuming that the user's account value is divided into three levels: high, medium, and low, different account values ​​correspond to different password change service methods. If the account value is high, the password change service method is determined to be the password change service method in S209; if the account value is medium, the password change service method is determined to be the password change service method in S210; if the account value is low, the password change service method is determined to be the password change service method in S208.

[0087] S207: Output the password change service mode for the user as no intervention at all.

[0088] In this embodiment, when the risk level of the user's behavior is higher than the first preset threshold, it indicates that the current password modification behavior is high-risk, and a completely non-interventional service method is adopted to avoid increasing the success rate of such high-risk password modification behavior.

[0089] S208, outputting a password change service mode to the user as a text message reminder.

[0090] Specifically, the user may be reminded via SMS to use other password-changing methods. For example, when the user fails to change the password through the security card verification method, the user may be reminded via SMS to change the password through mobile phone verification or dynamic password, thereby guiding the user to use a password-changing method that is more likely to succeed, thereby increasing the user's password-changing success rate; or, the user may be guided through SMS to complete the password change step by step, thereby increasing the user's password-changing success rate and the user's experience with the post-password change service.

[0091] S209: Outputting the password change service mode for the user as active phone call back.

[0092] The active telephone callback method refers to the method of contacting users through an artificial customer service phone to provide one-to-one service, thereby increasing the user's password change success rate and experience of the post-password change service through one-to-one manual service.

[0093] S210: Outputting the password change service mode to the user is pushing verification information.

[0094] For example, after a user fails to change their password, user information for verification (such as mobile phone number, the last four digits of their ID number, etc.) is pushed. If the pushed user information is correct, the user can complete the password change with one-click confirmation, thereby simplifying the user's password change method and helping the user to successfully change the password through post-services, thereby increasing the user's password change success rate.

[0095] It can be seen from the above embodiments that when a user fails to change his password, the password change service method for the user can be determined in a targeted manner based on the user's password change feature information (such as the urgency of password change, the degree of behavioral risk, the degree of lack of security, the account value, etc.), and then the corresponding password change service is performed on the user according to the determined password change service method, so that the post-service for the user who failed to change the password is more personalized, flexible and efficient, and can cover more users who failed to change the password, thereby improving the security service experience of users who failed to change the password and increasing user stickiness to the application.
