Describe content monitor method of the present invention and device in detail below in conjunction with accompanying drawing.
Fig. 1 shows contents supervision's configuration diagram of first embodiment of the invention.As shown in Figure 1, user 40, operation system 10, business management system 20 and CP/SP (content supplier/service provider) the 30th realize terminal use, network entity and the content and service provider (fellowship is realized contents supervision of the present invention) that relate in contents supervision's process.Wherein, user 40 is connected to operation system 10 via mobile network/fixed network, and operation system 10 is connected with business management system 20 with CP/SP 30 respectively, and CP/SP 30 also is connected with business management system 20.
Operation system 10 and business management system 20 are formed integrated value-added service system.The application number that the integrated value-added service system of being made up of operation system 10 and business management system 20 is submitted on December 8th, 2006 the applicant is 200610165901.1, exercise question is for the patent application of " a kind of integrated value-added service system and method for processing business thereof " and the application number submitted on January 29th, 2007 are 200710008381.8, exercise question is for the patent application of " a kind of content processing method and device that is used for integrated value-added service system " has a detailed description, and inserts specification, claims and the accompanying drawing of these two patent applications by reference at this.
Business management system 20 includes the various devices of supporting business system 10, such as AAA, service management device, user management device, user terminal management device, content/service provider's management devices, order relation management device and content processing apparatus 100.AAA, service management device, user management device, user terminal management device, content/service provider's management devices and order the relation management device and describe in detail in above-mentioned application number is 200610165901.1 patent application omit explanation to them at this.
The partial function of content processing apparatus 100 has also illustrated in above-mentioned application number is 200710008381.8 patent application, at this this part function has been repeated no more.In addition, in the present invention, content processing apparatus 100 also has contents supervision's function.
Operation system 10 comprises the miscellaneous service subsystem, such as WAP subsystem, Brew download system, Java download system, CAI e subsystem, Streaming Media subsystem, voice increment subsystem and SMG subsystem etc.In Fig. 1, service enabler 101, use to download 103, use download 105, mail treatment 107, medium download 109, to handle 113 be respectively the service enabler of WAP subsystem, Brew download system, Java download system, CAI e subsystem, Streaming Media subsystem, voice increment subsystem and SMG subsystem for speech processes 111 and note.In the present invention, operation system 10 has contents supervision's device (not shown) that is used to carry out the contents supervision, wherein this contents supervision's device can be independent of other building block in the operation system 10 and exist, and also can be deployed in service enabler in the operation system or other network entity (as service access gateway).
Fig. 2 shows the flow chart of the content monitor method of first embodiment of the invention.As shown in Figure 2, at first, CP/SP 30 will desire to offer content uploading that user 40 the uses content processing apparatus 100 (step S100) in the business management system 20.
After content processing apparatus 100 was received CP/SP 30 uploaded content, whether these uploaded content of content processing apparatus 100 audit qualified (step S102), for example, whether comprised the content of offencing against public morality etc.When auditing result shows that this uploaded content is qualified, it (can be the MD5 algorithm that content processing apparatus 100 uses predetermined cryptographic algorithm, also can be privately owned algorithm etc.) calculate the summary ciphertext (step S104) of this qualified content, and generate the identification information (step S106) that is used to identify this qualified content.Then, content processing apparatus 100 is stored the identification information of this qualified content and the mapping relations (step S108) between its summary ciphertext and the used cryptographic algorithm sign therein.Then, content processing apparatus 100 sends the identification information (step S110) of this qualified content to CP/SP 30.
Behind the identification information of receiving the content that content processing apparatus 100 sends, the identification information (step S112) of CP/SP 30 these contents of storage.
When CP/SP 30 desires when user 40 provides a certain certain content, CP/SP 30 is issued to operation system 10 (step S114) with this certain content and the identification information corresponding to this certain content stored.
After operation system 10 is received this certain content and identification information thereof that CP/SP issues, the content processing apparatus 100 of contents supervision's device in the operation system 10 in business management system 20 sends an algorithm web feed request message (step S122), wherein, this algorithm web feed request message includes the identification information of this certain content.
After the algorithm web feed request message of receiving from the contents supervision's device in the operation system 10, the identification information of this certain content that content processing apparatus 100 is comprised according to this algorithm web feed request message, from the mapping relations of wherein being stored, retrieve and corresponding summary ciphertext of the identification information of this certain content and cryptographic algorithm sign (step S124), then, the contents supervision device of content processing apparatus 100 in operation system 10 sends an algorithm summary response message (step S126), wherein, this algorithm summary response message comprises the summary ciphertext and the cryptographic algorithm sign of retrieval to some extent.
After the algorithm summary response message of receiving from content processing apparatus 100, contents supervision's device in the operation system 10 utilizes the represented cryptographic algorithm of this algorithm of receiving summary cryptographic algorithm that response message comprised sign that this certain content is carried out computations and obtains a summary ciphertext (step S128), then, this contents supervision's device compares to determine by the summary ciphertext that is comprised in the summary ciphertext that will calculate and this algorithm of the receiving summary response message whether this certain content is the definite result (step S130) of legal content and output.When the definite result who is exported when this contents supervision's device showed that this certain content is not legal content, operation system 10 issued this certain content to user 40 (step S132) with termination.When the definite result who is exported when this contents supervision's device showed that this certain content is legal content, operation system 10 was carried out the regular traffic flow processs and is issued this certain content and give user 40 (step S134).
