For addressing the above problem, the utility model provides a kind of digital Image Scrambling device, comprising: image collecting device is used to gather pending image; The scramble position is provided with module, is used for being provided with the position that pending image is intended the position of scramble; The scramble module is used for treating processing graphics according to the position that described scramble position is provided with the module setting and carries out scramble and handle, and forms the scramble image; The original image encoder is used for pending image is encoded, to form the original image information sign indicating number; The scramble image encoder is used for the scramble image is encoded, to form scramble image information sign indicating number; Select module, the Key Tpe that provides according to picture receiver is provided, the image information sign indicating number of decision Chuan send Give picture receiver is original image information sign indicating number or scramble image information sign indicating number; Display module, the image information sign indicating number that reduction and display image receiver receive.
Preferably, in the described digital Image Scrambling device, described Key Tpe comprises primary key that is complementary with scramble image information sign indicating number and the senior key that is complementary with the original image information sign indicating number.
Preferably, in the described digital Image Scrambling device, in described scramble module, adopt the Rijndael algorithm to carry out image scrambling.
Preferably, in the described digital Image Scrambling device, also comprise inspection module, be used for the image information sign indicating number that the checking image receiver receives and the matching state of Key Tpe, as finding the situation that do not match, then picture receiver quits work.
Preferably, in the described digital Image Scrambling device, described inspection module is set to start once every certain operating time.
Preferably, in the described digital Image Scrambling device, described certain operating time is 5 minutes.
Digital Image Scrambling device described in the utility model is by the mode of employing with cipher key match at different levels, the user who guarantees different stage obtains different image information sign indicating numbers, and every 5 minutes, check the corresponding relation of a secondary key and image information sign indicating number, to guarantee user's legal use to greatest extent.
Description of drawings
Fig. 1 is the structural representation of digital Image Scrambling device described in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
In the digital Image Scrambling device described in the utility model, comprising: image collecting device is used to gather pending image; The scramble position is provided with module, is used for being provided with the position that pending image is intended the position of scramble; The scramble module, being used for treating processing graphics according to the position that described scramble position is provided with the module setting carries out scramble and handles, form the scramble image, the position of scramble only limits to according to described scramble position the position that module is provided with is set, and need not whole pending image is carried out scramble; The original image encoder is used for pending image is encoded, to form the original image information sign indicating number; The scramble image encoder is used for the scramble image is encoded, to form scramble image information sign indicating number; Select module, the Key Tpe that provides according to picture receiver is provided, the image information sign indicating number of decision Chuan send Give picture receiver is original image information sign indicating number or scramble image information sign indicating number, that is to say, selecting module is the image that is transmitted according to the Key Tpe decision that picture receiver provides, if picture receiver can't provide key, the action of transmitted image does not then take place; Display module has decoder in the display module, can reduce and the image information sign indicating number that receives of display image receiver.
Image collecting device can be video camera, camera or camera, and the image of being gathered can be the image of a frame one frame in the continuous videos, also can be the photograph that is filmed.Each pending image all need adopt the scramble position that module is set and position intending the scramble position, handles because of need not that usually entire image is carried out scramble, handles and only need that key component is wherein carried out scramble.
In the described digital Image Scrambling device, described Key Tpe comprises primary key that is complementary with scramble image information sign indicating number and the senior key that is complementary with the original image information sign indicating number.The lower-level user can check scramble image information sign indicating number by primary key, and the higher-level user can check the original image information sign indicating number by senior key, need not like this scramble in the scramble image is partly carried out step of reducing, just can allow advanced level user check original image, save workflow, improved efficient.
In the described scramble module of described digital Image Scrambling device, adopt the Rijndael algorithm to carry out image scrambling.
In the described digital Image Scrambling device, also comprise inspection module, be used for the image information sign indicating number that the checking image receiver receives and the matching state of Key Tpe, as finding the situation that do not match, then picture receiver quits work.The situation if do not match then may be that digital Image Scrambling takes on existing fault, and more may be the invasion that the disabled user occurs, in this case, stops the work of picture receiver immediately, can stop original image to leak.
In the described digital Image Scrambling device, described inspection module is set to start once every certain operating time.And more specifically, described certain operating time is 5 minutes.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the execution mode, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
