Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
In the present embodiment, suppose following scene: some companies have bought the video-on-demand service of a certain grade of service, and stipulate that the employee can only use this service in company, must not use outside company's scope.In traditional WebVOD system, owing to only manage by the grade of username and password to Video service, therefore, traditional Web VOD system can't satisfy the regulation of the said firm.Of the present invention the VOD method of IP address with the user gradation combination can be addressed this problem effectively.
Before VOD method of the present invention was described, at first the structure to video on-demand system described.Video on-demand system of the present invention is based on Web VOD system, and this system is laying on the internet, and the user is by the Web webpage of this system of visit, and the browsing video programme information is selected the online broadcast of program.As shown in Figure 1, video on-demand system is made of three parts: client (Client), acting server (Proxy) and streaming media server (Streaming Media Server).Wherein, acting server is connected with streaming media server with client respectively by network, and also connects by network between client and the streaming media server.
Client comprises Web browser and DST PLAYER, also comprises the digest algorithm computing module that is used to calculate special IP address suffix.The user is by the client login system, browses, submission information, and adopts digest algorithm to realize the calculating of special IP address suffix.
Acting server carries out authentication and authorization to the user, for transfer between user and the Streaming Media is connected.Acting server comprises Web server and authentification of user, mandate, charging (AAA) server, also comprises the digest algorithm computing module that is used to calculate special IP address suffix in acting server.Web server has been preserved the programme information of showing streaming media server with form web page.In the database of aaa server, also stored the recorded information of the station address and the grade of service.Acting server removes to inquire about aaa server according to the information (usemame/password/User IP) that the user provides after receiving user's request, judge, corresponding service is provided or refuses illegal request.
Streaming media server then provides the flow-medium performance source for the client.
On the basis of above-mentioned video on-demand system, the VOD method of IP address with the user gradation combination described of the present invention.The user needs at first registered user's personal information before adopting method of the present invention to carry out video request program.When the user registers personal information, user's grade should be associated with user's IP address.As shown in Figure 3, specifically may further comprise the steps:
Step a, user are by network registry, and video on-demand system obtains user's IP address from user's request data package;
Step b, judge whether the user is the special user, if the special user, execution in step d then is if domestic consumer then carries out next step;
Special user described in this step is meant the user who needs to provide other grades of service in the network segment.Special user's IP address has the suffix different with the IP address of domestic consumer.
As can be known, in registration process, domestic consumer registers by the IP address prefix in the operating procedure below, and the special user then is the all-IP registration.Acting server in the video on-demand system can obtain user's IP address, but can't know user's registration classification, is complete IP address of registration or registration IP prefix in the time of just can't knowing registration.In the present invention, can realize identification with two kinds of methods to user type.A kind of method is the classification that he will register by the user notification acting server, and this registration classification information can be carried in the application for registration; Another kind method is to be judged user's type voluntarily by acting server, when judging, adopt digest algorithm to calculate the userspersonal information and the grade of service by acting server, the result after will calculating then and the suffix of IP address compare, if the result conforms to, then be the special user, otherwise be domestic consumer.
Acting server in step c, the video on-demand system extracts the prefix information in the IP address, then in conjunction with user's grade of service, and the address grade record of structuring user's, execution in step e then.The form of the address grade record of being constructed is as follows: (user gradation: the IP network address prefix).In this step, prefix information and user's grade of service of IP address is associated, makes that the user in the same network segment has the identical grade of service.
Acting server in steps d, the video on-demand system extracts user's complete IP address, comprises IP prefix and IP suffix information, then in conjunction with user's grade of service, and the address grade record of structuring user's.The form of the address grade record of being constructed is as follows: (user gradation: the complete IP of user address).
Acting server in step e, the video on-demand system extracts userspersonal informations such as user ID, password and user's grade of service from user's request data package, resulting userspersonal information is recorded in userspersonal information's table;
Step f, system store resulting userspersonal information's record among resulting address grade record and the step e among step c, the d in the database of aaa server into, in order to using in the Certificate Authority process from now on.
The user can realize order method of the present invention after registration finishes, as shown in Figure 2, of the present invention that the IP address is as follows with the specific implementation step of the VOD method of user gradation combination:
Step 10, user login audio/video player system, submit personal information to.The personal information that the user initiatively submits to when login comprises user ID, password, class of service information, and audio/video player system can also obtain user's IP address from the IP bag source address of logging request;
The acting server inquiry aaa server of step 20, audio/video player system, whether correct, if correct, carry out next step, otherwise return information to client, and stop further verification process according to the userspersonal information if writing down ID and the password of judging the user;
Step 30, acting server inquiry aaa server, whether the pairing grade of service of being put down in writing in judging the pairing grade of service of user ID and the address grade writing down of User IP prefix is consistent, if it is consistent, active user's IP is the common IP of network, by authentication, authorize corresponding authority,, carry out next step if inconsistent;
Step 40, acting server adopt digest algorithm that user ID, user cipher and the grade of service are calculated, the suffix that will calculate later result and special IP then compares, whether the IP that judges the active user belongs to " special " IP in the network segment, if, then by authentication, authorize corresponding authority, otherwise to client return authentication failure.
In this step, described " special " IP is meant the IP address that has special authority in the affiliated network segment, and special IP has the special suffix after the encryption, understand for convenience, below to involved in the present invention to several IP address be illustrated respectively:
The legal prefix of common legal IP=[]+[suffix at random]
The legal prefix of special legal IP=[]+[by the special suffix of digest algorithm generation]
Illegal IP=[illegal prefix]
In the present invention, because the network prefix of IPv6 address can be reacted the logical place (also can react certain geographical position) of user place network, and it is an important criterion distinguishing legal IP and illegal IP, therefore, in registration process, with the IP address prefix as a part with address grade recorded information, and in step 30, with the IP address prefix as a standard judging that the user is whether legal.By the application of network prefix, method of the present invention just can satisfy the requirement of " employee can only use this service in company, must not use " that present embodiment begins to be mentioned outside company's scope.
The suffix of IP address is to distinguish a common legal IP involved in the said method and the major criterion of special legal IP, for common legal IP, its suffix portion produces at random, and for special legal IP, its IP address suffix portion is the special suffix that generates by digest algorithm.For example, in an example, personal information such as user ID, password and user gradation information are done binding, the result after adopting the MD5 digest algorithm to binding then calculates, and obtains aforesaid special suffix.The computing formula of special IP suffix is as follows:
Special IP suffix=H (userspersonal information+grade of service)
Wherein, H represents the MD5 digest algorithm.
In actual applications, described digest algorithm can also be the digest algorithm of SHA1 digest algorithm and other kinds.When the user who uses special legal IP logins, the suffix of its IP address has adopted digest algorithm to calculate, therefore, in step 40, acting server adopts identical digest algorithm that user ID, user cipher and the grade of service are calculated, have only under all correct situation of user ID, password, the grade of service, resulting result of calculation is just identical with special user's IP address suffix.
By the application to IP address suffix, the particular client that the present invention can be in the network segment provides special service, and prevents the high-grade service of the illegal acquisition of domestic consumer.For example, if domestic consumer (as the employee) is arranged, attempt to use special user's (manager) network suffix to use the service of bypassing the immediate leadership, he comprises (ID: password: calling hierarchy: special IP) in the information that system is submitted to so.Acting server at first calculates the IP of domestic consumer suffix, be H (user ID+domestic consumer's password+class information), special IP suffix in the comparison of request information then, because special IP suffix is to be generated by special user's information (manager ID+ manager password), therefore the acting server comparison both can obtain inconsistently, and then refuse this illegal request.
In step 40, the result of calculation of a user's IP address suffix can also be stored in the AAA database, then the user is when visiting next time, and acting server does not need to recomputate, and can directly utilize result of calculation last time, helps improving the efficient of system.
It should be noted last that above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is made amendment or is equal to replacement, do not break away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
