The disclosure can be limited.
Detailed description of the invention
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art be briefly described, it should be apparent that, it is described below
Attached drawing is one embodiment of the present invention, for those of ordinary skill in the art, before not making the creative labor
It puts, is also possible to obtain other drawings based on these drawings.

Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, described embodiments are some of the embodiments of the present invention, rather than whole
Embodiment.
Embodiment one:
Fig. 1 is a kind of network image copyright information guard method flow chart of first embodiment of the invention, as shown in Figure 1, the party
Method includes following two steps.
Step S101: image source information is added in image.Specifically, in the image of input, digital water is used
Print insertion or image latent writing method, image source information is added in image.
In an alternative embodiment, the source-information of image includes author or the uploader, upload image end of image
IP address, the upload date at end etc..The digital watermark embedding or image latent writing method used include: least significant bit method (LSB),
Spread-spectrum watermark embedding grammar etc..By these methods, by the source-information write-in image of image, due to image watermark can not
Perceptibility, visually the image after embedded images source-information is no difference with when being not embedded into.
Step S102: the archive information of image and image are stored respectively.Specifically, image information and image sources are believed
Breath after private key encryption, forms the archive information of image, archive information is stored in and schemes using after private key encryption
As at least one different position of physical storage locations.In detail, image information include: image data generate identification information or
Informative abstract, characteristic information, the attribute information of image.
In an alternative embodiment, the characteristic information of image includes that image passes through mathematics or the feature of logical operation letter
Breath, the attribute information of image includes the size of image, pixel resolution of image etc..The identification information that image data generates, packet
It includes and the cryptographic Hash that SHA256 operation generates is implemented to image data, which has uniqueness；Or it is calculated using HD5 informative abstract
Image data is generated informative abstract by method.Image information and source-information are encrypted using private cipher key, added asymmetric
In close, encryption key and decruption key be not identical.Wherein encryption key is private cipher key, and decruption key is Public Key.Encryption
Archive information of the information afterwards as image is stored at least one position different from image physical storage locations.Described
At least one position: common storage location, third party's credit position, network distribution type memory node, after information is stored in position
It can not modify.It can not modify and can be realized in terms of software and hardware two after information storage, in software view, from data access authority control
In configuration, setting only has data to add permission, prevents the modification and deletion that carry out data；In hardware view, memory is set as
Data are only added, data modification and erasing is not available for, specifically, such as uses the CD burning skill of one-time write data
Art.Image data stores respectively with encrypted image file information, is distorted and is destroyed simultaneously to avoid the two.
Step S103: the propagation information of image is associated with image.Specifically, the copy for generating at least one image,
In the copy of at least one image, using digital watermark embedding or image latent writing method, image copy is added in image copy
Identification information；In image output, a copy is selected from the copy of at least one image, by the identification information of copy and
Recipient's information of image is associated storage.
In an alternative embodiment, the image duplication of storage is generated into 3 copies, each image copy passes through number
Image copy is written in the identification information of image copy by watermark insertion or image latent writing method, such as first image copy
Identification information is that image mark information adds " _ 1 ", and so on, second is respectively that image mark information adds with third
" _ 2 " and " _ 3 ".In image output, a copy, such as identification information is selected to end up with " _ 1 " from 3 image copies
Image copy is sent to the recipient of image.The IP address of image recipient or user information and the image copy of selection are identified
Information is stored in database together, and generates the new identification information image copy to end up with " _ 4 ", deletes with " _ 1 " ending
Identification information image copy.Image next time output in, then from be with " _ 2 ", " _ 3 " and " _ 4 " end up three copies in
It chooses.This ensure that the identification information that the image copy exported every time is included is different, so that image propagates chasing after for link
Track.
In another alternative embodiment, parallel calculating method of the output image as unit of pixel, uses digital water
Print insertion or image latent writing method, recipient's information of image is added in image；If output image is image sequence, with
Image and image pixel two-stage parallel calculating method, using digital watermark embedding or image latent writing method, by the recipient of image
Information is added in image sequence.In current parallel-processing hardware, Pixel-level is carried out using hardware such as CPU, GPU or FPGA
Parallel processing is realized in order to carry out real-time digital watermark insertion or image latent writing method.Before image output, duplication will be defeated
The information of image recipient is added in image using above-mentioned parallel algorithm, and is exported by image out.In this way, every
The information of image recipient is contained in the image of secondary output, all so that image propagates the tracking of link.
Step S104: image copyright Information Authentication.Specifically, using digital watermarking or image latent writing information extracting method,
The information in image is extracted, to identify the source-information or recipient's information of image；Use the archives of Public Key decrypted image
Information, with the identity information of authentication image.
In an alternative embodiment, in order to verify the source of certain image, digital watermarking or image latent writing information are utilized
Extraction algorithm extracts the source-information being added in image or recipient's information；For the identity of authentication image itself, life is calculated
At the identification information of image, it is compared in conjunction with the source-information extracted using Public Key decrypted image archive information,
With the identity information of authentication image.
