Description
Technical field
The invention belongs to the digital copyright management technical field, specifically, relate to a kind of system that in the digital resource transaction, realizes credible counting.
Background technology
Digital copyright management (Digital rights management:DRM) is a kind of method that multimedia digital content is avoided encroaching right and play and propagate under the protecting network environment.Digital copyright management relates to multiple programs such as the making of department in the digital resource communication process in many ways such as content supplier, content consumer, sales of the contents merchant, supervision department, distribution, mandate, control, its objective is the intellecture property and the legitimate rights and interests of protection relevant party.
The technological core of DRM be the protection digital resource not by unwarranted use, when that is to say the legal use digital resource of user, must be through authorizing.The method that obtains mandate is to buy the digital resource of process encryption and obtain the legal authorization file through authentication simultaneously through transaction, and the digital resource that buys only could be deciphered behind acquisition legal authorization file, and normally uses.
The DRM system mainly is made up of DRM background server system and client.Transaction, download, control client device that client is responsible for digital resource use digital resource according to the authorization of authority; The background server system then accomplishes digital resource and encrypts storage, transaction control, authority generation and distribution etc.But; Present DRM system is mostly set up by digital resource dealer; Accomplish the digital resource controls transactions by the background server system, do not distinguish the role of digital resource provider, dealer usually, all " transaction count " data all by digital resource dealer from line item; Cause the data deficiency of " transaction count " credible, make each side such as content supplier, content consumer, sales of the contents merchant, supervision department lack the digital resource transaction count data of objective and fair.Particularly when the counting difference took place, the one-sided data deficiency that is recorded in the DRM system was credible.
Summary of the invention
To the problems referred to above, the present invention provides the system that realizes credible counting in a kind of digital resource transaction, to solve the credible problem of transaction count data deficiency in the existing digital copyright management.In the digital resource communication process, relate to a plurality of roles such as content supplier, content consumer, sales of the contents merchant, supervision department; After adopting the present invention; Can carry out objective, believable counting to digital resource transaction; So that carry out the calculating of tranaction costs, with intellecture property and the legitimate rights and interests of protecting each role according to enumeration data.
The present invention realizes through following technological means: realize the system of credible counting in the digital resource transaction, comprise credible counting server, Client Agent, system for numeral copyright management and digital resource transaction system; Said system for numeral copyright management is implemented copyright control to digital resource, generates authority; The digital resource transaction system is then accomplished the sale and the transaction of digital resource; Said Client Agent is installed on the digital resource transaction system; Receive copyright and Transaction Information that the digital resource transaction system is submitted to,, generate the transaction count packet through handling; Send to credible counting server, said credible counting server authentication and store transaction enumeration data.Said transaction count data comprise transaction user, transaction form, number of transaction, exchange hour, transaction user's signature information, trade rights object information, copyright access times and authority information, the trade rights object term of validity.
The present invention also can do following improvement:
Said credible counting server also comprises secure communication module one, is used for setting up secure communication channel with Client Agent, receives credible transaction data; Said Client Agent also comprises secure communication module two, is used for setting up secure communication channel, submitting credible transaction data to server with credible counting server.
