Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application shall fall within the scope of protection of the present application.
Referring to fig. 1, the present application provides an authentication method based on a browser plug-in, and when applying the technical solution of the present application, a user needs to specify the plug-in the browser. The designated plug-in may be a pre-edited program component that performs its function when the browser is started. The method may include the following steps.
S1: when the designated plug-in carries out initialization configuration in the browser, inputting user information and a signature key of a user;
s2: when a target site is accessed through the browser, an access request sent outwards by the browser is acquired;
s3: generating signature information based on the signature key, and attaching the signature information and the user information to the access request;
s4: and sending the access request attached with the signature information and the user information to a server of the target site.
In this embodiment, when the specified plug-in performs initialization configuration in the browser, the method further includes:
entering a protected site list;
and the plug-in detects a current site accessed by the browser, and if the current site is in the protected site list, an access request sent to the current site is acquired through an application programming interface of the browser.
In this embodiment, attaching the signature information and the user information to the access request includes:
and filling the signature information and the user information in a user-defined field in the access request.
In this embodiment, generating the signature information based on the signature key includes:
and according to a specified encryption algorithm, converting the signature key into signature information encrypted by the specified encryption algorithm.
In this embodiment, the method further comprises:
the server of the target site receives an access request sent by the browser and extracts the user information and the signature information from the access request;
acquiring a target signature key matched with the user information from a database based on the user information;
encrypting the target signature key according to the specified encryption algorithm to obtain target signature information;
and comparing the target signature information with the extracted signature information, and processing the access request according to a comparison result.
In this embodiment, the processing the access request according to the comparison result includes:
when the target signature information is consistent with the extracted signature information, allowing the browser to access the target site;
and when the target signature information is inconsistent with the extracted signature information, rejecting the access request.
In one application example, a user may install a specified plug-in a browser, and upon completing an initial configuration of the specified plug-in the browser, the user may enter user information (e.g., a username), a signature key (e.g., a string of characters that may be user-defined), a list of protected sites, and so forth. Therefore, when the browser accesses the sites in the protected site list, the information authentication method can be automatically started. It should be noted that, the user information and the signature key and other information entered by the user may be synchronously backed up to the server of the protected site.
Specifically, when the specified plug-in detects that the user is accessing the protected target site, an access request to be sent out by the browser may be acquired through an Application Programming Interface (API) of the browser. Of course, in practical applications, only part of the parameters in the access request may be obtained, which is not limited in the present application.
After the access request is obtained, the specified plug-in can read the signature key which is input by the user before, and encrypt the signature key according to the specified encryption algorithm so as to ensure the security of the information. The specified encryption algorithm may be DES, RSA, MD5, etc. After the encryption process is performed, signature information can be obtained. In this way, the designated plug-in may attach the signature information and the user information of the user to the access request. Specifically, the access request may have a user-defined field, so that the specified plug-in may write the signature information and the user information of the user into the user-defined field. After these steps are completed, the browser may send an access request with additional information to the server at the target site.
Referring to fig. 2, when the server receives an access request from the browser, user information and signature information may be extracted from the access request. At this time, the server may further determine whether the extracted signature information is legitimate. Specifically, the server may read the matching signing key in a local database according to the extracted user information. The read signing key may then be encrypted using the same specified encryption algorithm to obtain the target signing information. At this time, the target signature information may be compared with the signature information extracted from the access request, and when the target signature information is consistent with the extracted signature information, the browser is allowed to access the target site; and when the target signature information is inconsistent with the extracted signature information, rejecting the access request. Meanwhile, the log recording module of the server can record the verification result.
Therefore, the designated plug-in can be installed in the browser, and the signature key of the user can be pre-entered when the designated plug-in is initialized and configured. The designated plug-in may detect a site that the browser is about to visit. When the browser is about to send an access request to the server of the site, the access request may be intercepted and the signing information encrypted by the signing key may be appended to the access request. Therefore, when the server of the site receives the access request, the signature information can be extracted from the access request, the signature key of the user stored locally is encrypted and then is compared with the extracted signature information, and if the signature key of the user is consistent with the signature key of the user, the access request is legal, so that the browser is allowed to normally access the site. If the two are not identical, the access request is not legal, and the access request is rejected. Therefore, the user does not need to perform additional processing on the access request, and the user is unaware in the whole process, so that the information safety can be improved under the condition of improving the user experience.
Referring to fig. 3, the present application further provides an authentication system based on a browser plug-in, where the authentication system includes a browser installed with a specified plug-in, and the authentication system further includes:
an information entry unit 100, configured to enter user information and a signature key of a user when the specified plug-in performs initialization configuration in the browser;

an access request sending unit 400, configured to send the access request with the signature information and the user information attached to the server of the target site.
In this embodiment, the system further comprises:
the site list entry unit is used for entering a protected site list;
and the judging unit is used for controlling the plug-in to detect the current site accessed by the browser, and acquiring an access request sent to the current site through an application programming interface of the browser if the current site is in the protected site list.
In this embodiment, the information attaching unit includes:
and the encryption module is used for converting the signature key into the signature information encrypted by the specified encryption algorithm according to the specified encryption algorithm.
In this embodiment, the system further comprises:
an information extraction unit, configured to control a server of the target site to receive an access request sent by the browser, and extract the user information and the signature information from the access request;
