Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Figure 1 shows that the flow chart of the method that file that preferred embodiment according to the present invention provides is reviewed.As shown in Figure 1, the file that provides of the preferred embodiment of the present invention method of reviewing comprises step 101～103.
Step 101: the user creates a file, and calculates the cryptographic Hash of described file correspondence in client.
Particularly, described file comprises arbitrarily the file that can preserve at client or server, for example text, audio or video file etc.Client comprises being the software of cryptographic Hash with described file conversion, wherein, the cryptographic Hash difference of different file correspondences, namely the cryptographic Hash of each file is unique.
Step 102: described client sends to server with cryptographic Hash and the file specification of described file correspondence, and whether described server lookup self has stored the cryptographic Hash of described file correspondence.
Particularly, after the user calculates the cryptographic Hash of file correspondence in client, can add the file specification part to described file.Described file specification can comprise author information and creation time.In this, the detailed content of described file specification part can be defined voluntarily by the user, also can be sky, yet, this present invention is not limited.
If the cryptographic Hash of described file correspondence has been stored in server lookup self, then described server returns refusal information to described client, and existing other people of prompting user is at the described file of server stores.
Step 103: if not, described server is preserved cryptographic Hash and the file specification of described file correspondence.
Particularly, if the cryptographic Hash of described file correspondence is not stored in server lookup self, then cryptographic Hash and the file specification that the user is sent preserved in this locality.In present embodiment, when server is preserved described cryptographic Hash, also preserve the time of reception of described cryptographic Hash.
In present embodiment, the cryptographic Hash of server stores and file specification are read only attribute, and user's query function only is provided.Behind user's game server, can specify cryptographic Hash in the server end input, inquire about described server and whether stored described appointment cryptographic Hash.
Figure 2 shows that the schematic diagram of the system that file that preferred embodiment according to the present invention provides is reviewed.As shown in Figure 2, the system that the file that preferred embodiment of the present invention provides is reviewed comprises client 201 and server 202, and described client 201 connects described server 202.Described client 201 is used for the cryptographic Hash of calculation document correspondence, and cryptographic Hash and the file specification of described file correspondence sent to server 202.Described server 202 is used for inquiry and self whether has stored the cryptographic Hash of described file correspondence, and if not, described server 202 is preserved cryptographic Hash and the file specification of described file correspondence.Operating process about said system is described with above-mentioned method, so repeat no more in this.
In sum, the method and system that the file that preferred embodiment provides according to the present invention is reviewed, client sends to server with cryptographic Hash and the file specification of file correspondence, and whether server lookup self has stored the cryptographic Hash of described file correspondence.Guarantee that thus same file only in the server preservation once.If server does not have the cryptographic Hash of storage file correspondence, then server is preserved cryptographic Hash and the file specification of described file correspondence.So, can effectively trace back to original author's works the first time upload server time, can provide corresponding evidence for the original author protects self rights and interests.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
