The embodiment of the application provides a login authentication method, and in order to more clearly describe the scheme of the application, some drawings related to the application are further described below.
Referring to fig. 1, fig. 1 is a flowchart of a login authentication method according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
s101, when a first login instruction triggered by a browser of a first device through a target account is detected, determining whether the first device installs at least one first application program in a preset application program list, wherein the preset application program list comprises N application programs, and N is an integer greater than 1;
in this embodiment of the present invention, a user may log in a target account through a browser of a first device, for example, the user inputs a target account and a password in a login interface of the browser of the first device to log in, or, the user temporarily switches a browser to log in the target account on the same device. In order to ensure the security of user account login, the device used by the account login is generally identified, and if the target account login is performed by using the same device each time, the target account login is considered to be a secure login.
Specifically, optionally, when a first login instruction triggered by the target account passing through the browser of the first device is detected, a preset application program list is obtained, where the preset application program list includes N application programs to be tested, optionally, all the N application programs may be the same test application program, and then the N application programs may be some commonly used application programs. Alternatively, the N applications may be applications determined for certain characteristics of the user of the target account, e.g., the N applications may be applications determined for industries and/or hobbies engaged in by the user of the target account. Illustratively, the N applications include applications for a particular industry, and/or the N applications include applications specific to certain interests, and the like. The value of N may be the number of bits of the fingerprint identifier of the browser, for example, the preset application program list may include 32 application programs.
And sequentially detecting whether the first device has installed the application programs in the preset application program list, and if the first device installs a certain application program, determining the first device as the first application program.
The method for detecting whether the first device installs the application program may be to acquire an address header of the application program, call a local application access interface of the browser, and access an application program corresponding to the address header installed locally on the first device through the local application access interface. If the application is installed locally at the terminal device, the browser will output a confirmation dialog for asking if the application is to be run. If the application is not installed locally at the terminal device, the browser will not output the confirmation dialog. It is possible to determine whether the application is installed locally by detecting whether the browser outputs the confirmation dialog.
S102, if the first device installs at least one first application program in the preset application program list, generating a first browser fingerprint identifier according to the at least one first application program, wherein the first browser fingerprint identifier comprises N bit positions corresponding to the N application programs, and at least one bit position corresponding to the at least one first application program in the N bit positions is set to be a preset value;
In one embodiment, the first browser fingerprint identifier is generated further in accordance with the first device installing at least one first application in the list of preset applications. For example, N applications in the preset application list may be arranged in a specific order, the N applications corresponding to N bits, and if the first device installs the application, the corresponding bits are set to a preset value, which may be 1 or 0. If the preset value is 1, among the N bits, if the first device does not install a certain application in the preset application list, the corresponding bit is 0. If the preset value is 0, among the N bits, if the first device does not install a certain application in the preset application list, the corresponding bit is 1.
Specifically, alternatively, whether the first device installs the application program in the preset application program list is sequentially detected, if the terminal device installs the application program, the bit value of the corresponding bit may be set to 1, and if the terminal device does not install the application program, the bit value of the corresponding bit may be set to 0, thereby obtaining the N-bit first browser fingerprint identifier. For example, the application programs included in the preset application program list are an application program a, an application program B, and an application program C in this order. If the terminal device installs application a and application C, and does not install application B, the corresponding first browser fingerprint identifier is 101.
In particular, a script may be added to the website, which will test each application in the application list, and which will return an ordered array of boolean values whose values are used to indicate whether the terminal device has installed an application in the application list. If the terminal equipment installs the application program, each Boolean value is true; otherwise, false. This array is referred to as a permanent first browser fingerprint identifier, which may also be referred to as a cross-browser identifier.
According to the method and the device, whether the first device used for logging in the target account installs the application program in the preset application program list is detected, so that the browser fingerprint identifier is determined, instead of being generated through information of the browser, and therefore mismatching of the browser fingerprint identifier obtained during logging in across the browser is avoided, and device identification errors are caused.
S103, matching the first browser fingerprint identifier with a pre-stored second browser fingerprint identifier, wherein the second browser fingerprint identifier is generated based on the fact that a second device installs at least one second application program in the preset application program list, and the second device is the device for historical login of the target account;
S104, if the first browser fingerprint identifier is matched with the second browser fingerprint identifier, determining that the first device and the second device are the same device, and loading a login page after successful login through a browser of the first device.
In this embodiment of the present application, the pre-stored second browser fingerprint identifier also includes N bits, where the second browser fingerprint identifier is used to represent an application installed on the device that is logged in by the target account. Alternatively, the second browser fingerprint identifier may be obtained through the following step one-step three, which is specifically described below:
step one, receiving a login request sent by a browser of second equipment, wherein the login request comprises the target account number and verification information;
the second device may be the same as or different from the first device, and the user may input the target account number and verification information on a login interface of a browser of the second device for login, where the verification information may be a password or biometric information, such as a face or a fingerprint, and the like.
Step two, verifying the verification information, and if the verification information passes the verification, determining that the second device has installed at least one second application program in the preset application program list;
Specifically, if the verification information passes verification, for example, the verification information in the login request is matched and consistent with the pre-stored verification information, loading a login page after successful login through a browser of the second device. Further, in order to facilitate the subsequent user to log in quickly when logging in the same device, it is further determined that the second device has installed at least one second application in the preset application list, where a detection manner for detecting that the second device has installed an application may refer to a detection manner for detecting that the first device has installed an application in the foregoing embodiment, which is not described herein again.
And thirdly, generating a second browser fingerprint identifier according to the at least one second application program, and storing the second browser fingerprint identifier, wherein the second browser fingerprint identifier comprises N bits corresponding to the N application programs, and at least one bit corresponding to the at least one second application program in the N bits is set to be the preset value.
And generating a second browser fingerprint identifier according to at least one second application program in the preset application program list already installed by the second device. For example, N applications in the preset application list may be arranged in a specific order, the N applications corresponding to N bits, and if the second device installs the application, the corresponding bits are set to a preset value, which may be 1 or 0. If the preset value is 1, among the N bits, if the second device does not install a certain application in the preset application list, the corresponding bit is 0. If the preset value is 0, among the N bits, if the second device does not install a certain application in the preset application list, the corresponding bit is 1.
Through the first step to the third step, a pre-stored second browser fingerprint identifier can be obtained, after the user logs in through the first step to the third step in one browser of the second device by using the target account, the user can also switch the browser to log in, or after a certain period of time after the user logs in through the first step to the third step, the user can also log in again by using the browser of the other first device, and the target account and the verification information are input in the browser of the other first device.
When the target account number is detected to be logged in through the browser of the first device, whether the first device installs an application program in a preset application program list or not is determined, and therefore an N-bit first browser fingerprint identifier is generated. Reference may be made specifically to the descriptions of the foregoing steps S101 to S102, and the descriptions are omitted here.
If the first browser fingerprint identifier is the same as the pre-stored second browser fingerprint identifier, the application installed by the first device currently logged in and the application installed by the second device used for historical login of the target account are the same, and the application installed in the device usually keeps stable for a period of time, so when the first browser fingerprint identifier is detected to be the same as the pre-stored second browser fingerprint identifier, the target account is determined to be logged in by using the same device.
Further, when the target account is determined to be logged in by using the same terminal equipment, further verification of the login of the target account is not required, so that the user can use the target account conveniently. For example, the user may log in the target account by switching the browser within a preset time (for example, within 2 minutes) of the same device, and directly load the log-in page after successful log-in without inputting the verification information again, or the user may log in the target account and the verification information, and further verification of the identity of the user is not required, for example, face recognition verification is not required any more, because it is determined that the target account is logged in by using the same device.
In this embodiment of the present application, when a login instruction triggered by a target account passing through a browser of a first device is detected, it is determined that the first device has installed at least one first application program in a preset application program list, where the preset application program list includes N application programs, and a first browser fingerprint identifier is further generated, where the first browser fingerprint identifier includes N bits corresponding to the N application programs, at least one bit corresponding to the at least one first application program in the N bits is set to a preset value, the first browser fingerprint identifier and a pre-stored second browser are matched, if they are identical, the login device of the target account is considered to be identical, and a login page after successful login is loaded.
Referring to fig. 2, fig. 2 is a flowchart of another login authentication method according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:
s201, when a first login instruction triggered by a browser of a first device through a target account is detected, determining whether the first device installs at least one first application program in a preset application program list, wherein the preset application program list comprises N application programs, and N is an integer greater than 1;
s202, if a first device installs at least one first application program in a preset application program list, generating a first browser fingerprint identifier according to the at least one first application program, wherein the first browser fingerprint identifier comprises N bits corresponding to the N application programs, and at least one bit corresponding to the at least one first application program in the N bits is set to a preset value;
s203, matching the first browser fingerprint identifier with a pre-stored second browser fingerprint identifier;
s204, if the first browser fingerprint identifier is matched with the second browser fingerprint identifier, determining that the first equipment is identical with the second equipment, and loading a login page after successful login through a browser of the first equipment.
Please refer to step S101 to step S104 in the embodiment of fig. 1 in step S201 to step S204 in the embodiment of the present application, and the description is omitted here.
S205, if the first browser fingerprint identifier and the second browser fingerprint identifier are not matched, acquiring target matching degree of the first browser fingerprint identifier and the second browser fingerprint identifier;
in this embodiment of the present application, if the first browser fingerprint identifier and the second browser fingerprint identifier are not matched, it is indicated that the application installed by the first device currently logged in of the target account and the application installed by the second device used for historical login are different, and generally, the application installed in the device will remain stable within a period of time, so when detecting that the first browser fingerprint identifier and the pre-stored second browser fingerprint identifier are different, it is determined that the target account is logged in using different devices.
S206, determining a matching degree range to which the target matching degree belongs, and acquiring verification modes corresponding to the matching degree range, wherein different matching degree ranges correspond to different verification modes;
s207, verifying the target account by adopting a verification mode corresponding to the matching degree range, and if the verification is passed, loading a login page after successful login through a browser of the first device.
Specifically, when it is determined that the target account number is logged in by using different devices, in order to ensure the login security of the account number, further verification may be performed on the user, for example, fingerprint identification, face recognition, and the like are required for the user, if the verification is passed, the logged-in interface is loaded, or the user is required to reenter verification information for verification, and when the verification information passes the verification, the logged-in interface is loaded.
Optionally, when the first browser fingerprint identifier and the second browser fingerprint identifier are determined to be not matched, the matching degree between the first browser fingerprint identifier and the second browser fingerprint identifier can be further obtained to determine a verification mode of further verification, if the matching degree is higher, a looser first verification mode can be used for verification, and if the matching degree is lower, a stricter second verification mode can be used for verification, namely, the strength of the second verification mode is higher than that of the first verification mode. The degree of matching may refer to the ratio of the number of bits of the matching bits to N in the browser identifier.
For example, different verification modes corresponding to different matching degree ranges can be preset, after the target matching degree between the first browser fingerprint identifier and the second browser fingerprint identifier is obtained, the matching degree range to which the target matching degree belongs can be further determined, verification access corresponding to the matching degree range is obtained as a target verification mode to verify the target account, and if verification is passed, a login page after successful login is loaded through the browser of the first device.
Optionally, in a scene with a lower matching degree, the category of the application program which is already installed by the second device and registered by the target account history can be determined according to the second browser identifier, and the category of the application program which is already installed by the first device and registered by the target account currently can be determined according to the first browser identifier, if the two categories are completely different, the operation of the user is determined, the user is refused to register, and the security of the system is increased.
Referring to fig. 3, fig. 3 is a flowchart of another login authentication method according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of:
s301, when a first login instruction triggered by a browser of a first device through a target account is detected, determining whether the first device installs at least one first application program in a preset application program list, wherein the preset application program list comprises N application programs, and N is an integer greater than 1;

S303, matching the first browser fingerprint identifier with a pre-stored second browser fingerprint identifier;
s304, if the first browser fingerprint identifier is matched with the second browser fingerprint identifier, loading a login page after successful login through the browser of the first device.
Please refer to step S101 to step S104 in the embodiment of fig. 1 in step S301 to step S304 in the embodiment of the present application, and the description is omitted here.
S305, if the first browser fingerprint identifier and the second browser fingerprint identifier are not matched, acquiring application categories to which each first application program in the at least one first application program belongs;
s306, determining a first user portrait according to the application category to which each first application program belongs;
in this embodiment of the present application, if the first browser fingerprint identifier and the second browser fingerprint identifier are not matched, it is indicated that the application installed by the first device currently logged in of the target account and the application installed by the second device used for historical login are different, and generally, the application installed in the device will remain stable within a period of time, so when detecting that the first browser fingerprint identifier and the pre-stored second browser fingerprint identifier are different, it is determined that the target account is logged in using different devices.
Further, at least one first application program in the N application programs installed on the first equipment is obtained, and the first user portrait is determined according to the application category of each first application program in the at least one first application program. The first user portrait may include a professional tag, an interest tag, an age tag, and the like of the user.
For example, among the N applications, at least one first application that the first device has installed includes: the fund stock class application and the sports class recording application, determining the tag of the first user representation may include: finance, sports. For another example, among the N applications, at least one first application that the first device has installed includes: applications for listening to songs and singing, shopping, and the like, determining the tag for the first user representation may include: shopping online, singing, young women.
By way of example, the determination of the corresponding user representation by application class may be determined by a trained classification model, such as, for example, inputting the determined application class into a trained classification model to determine feature labels, which may include, but is not limited to, support vector machines (Support Vector Machine, SVM), gradient boost decision trees (Gradient Boosting Decision Tree, GBDT), and the like. The classification model can be obtained by training data in a training set in advance, the data in the training set comprises application category sets, each application category set comprises application categories, each application category set is marked with a characteristic label, and the classification model is trained through the data in the training set until the model converges, so that a trained classification model is obtained.
S307, acquiring a pre-stored second user portrait, wherein the second user portrait is determined according to application categories of all second application programs in the at least one second application program;
in this embodiment of the present application, the pre-stored second user portrait is determined according to an application category to which each second application program in at least one second application program installed in the second device that is logged in by the target account history. The second user portrait obtaining method may refer to the first user portrait obtaining method, which is not described herein.
S308, determining a target verification mode according to the first user portrait and the second user portrait;
s309, verifying the target account by adopting the target verification mode, and if the target account passes the verification, loading a login page after successful login through a browser of the first device.
The first user portrait may include at least one first feature tag, the second user portrait may include at least one second feature tag, and further obtain a portrait matching degree of the first user portrait and the second user portrait, where the portrait matching degree is a ratio between a number of feature tags matched in the first user portrait and the second user portrait and a maximum number of feature tags included in user images including a larger number of feature tags in the first user portrait and the second user portrait. For example, the first user portrait includes 5 feature tags, the second user portrait includes 10 feature tags, and the number of feature tags matched in the first user portrait and the second user portrait is 3, so that the portrait matching degree is 3/10=0.3. Further, the target verification method corresponding to the image matching degree is obtained to verify the target account number, and for example, a matching degree range to which the image matching degree belongs can be obtained, the verification method corresponding to the matching degree range is used as the target verification method, and different matching degree ranges correspond to different verification methods.
For example, if the portrait matching degree between the second user portrait and the first user portrait is greater than a first threshold, the user is authenticated by a first authentication method, if the portrait matching degree between the second user portrait and the first user portrait is less than or equal to the first threshold and greater than a second threshold, the user is authenticated by a second authentication method, the intensity of the second authentication method is greater than the intensity of the first authentication method, and if the matching degree between the second user portrait and the first user portrait is less than or equal to the second threshold, the user is denied login.
Further optionally, if the user is authenticated by the target authentication method, the user may update the second user portrait to the first user portrait, and the first user portrait may be used as a matching criterion subsequently.
Further, after the user passes the verification in the target verification manner, the prestored second browser fingerprint identifier may be updated, that is, the second browser fingerprint identifier is updated to be the first browser fingerprint identifier, optionally, before the browser fingerprint identifier is updated, a first option for indicating that the prestored browser fingerprint identifier is allowed to be updated and a second option for indicating that the prestored browser fingerprint identifier is not allowed to be updated may be output, and when an operation acting on the first option is detected, the prestored second browser fingerprint identifier is updated to be the first browser fingerprint identifier. For example, after the user changes the mobile phone, the browser fingerprint identifier is updated and stored, and if the user temporarily changes the device to log in, the browser fingerprint identifier can be not updated.
