In addition, if below in the described different embodiment of the present invention involved technical characteristic do not form conflict each other and just can be combined with each other.
Embodiment 1
There is provided a kind of digital resource copy-right protection method in the present embodiment, the method can be used in the copyright protection based on the mass digital resources of hardware storage device, and the method process flow diagram as shown in Figure 1, comprises the steps:
S01, the first key is used to carry out digital resource content-encrypt to digital resource.Be the copy protection encryption carried out the content of digital resource, if the first key is key A, encryption method is DRM encryption herein.
S02, use the second double secret key first key to be encrypted, the information according to described encryption generates encrypted certificate.
When producing in batches digital resource, during as a collection of e-book wanted batch authorization to some mobile phones, now superencipher is carried out to above-mentioned key A, the second key is herein key B, when digital resource batch authorization, select key B to carry out superencipher to key A, and generate a encrypted certificate for this digital resource, store the second double secret key first key in this encrypted certificate and be encrypted information.
Digital resource and the encrypted certificate of encryption is just obtained by step S1 and S2.
S03, by encryption after digital resource and described encrypted certificate send in each hardware storage device.In this step, the digital resource of above-mentioned encryption and encrypted certificate are sent and gives all hardware storage device, namely batch authorization is carried out to digital resource.
S04, the unique identification of described second key and described hardware storage device to be bound, generate the authority of this hardware storage device.
In this step, key B binds the unique identification of hardware storage device, generates authority, and this authority is used for authorizing copyright protection platform.
In the method, in the batch authorization production run of digital resource, adopt twice encryption, once authorize, first time encryption is the original encryption of resource, and encryption method is DRM encryption, and key is A, the key B that second time encryption uses when being and using primary key A and batch to produce is encrypted, and generates a certificate for each digital resource simultaneously; Authorize and then bind according to the unique identification of key B and hardware store, simultaneously for hardware store generates a power of attorney.When producing in batches, as long as do one time twice encrypted work, then make a certificate of authority for each hardware store, the time that the binding greatly reducing hardware store and digital resource consumes.The production efficiency of the magnanimity copyright protection resource based on binding memory device can be improved by the program, reduce production cost, meanwhile, ensure the copyright protection of resource, prevent resource to be copied and usurp, also break away from the dependence of hardware resource protection to hardware device.
