Embodiment
The invention provides a kind of picture safe sharing implementation method and system, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the process flow diagram of picture safe sharing implementation method of the present invention preferred embodiment, said method comprising the steps of:
Step S100, when transmitting terminal detect user picture send instruction time, then obtain the rgb value of each pixel in picture to be sent, answer rgb value to carry out XOR the rgb value of each pixel and current selected Color pair, obtain XOR image data, and be sent to receiving terminal.
In embodiments of the invention, when picture to be sent need be shared by transmitting terminal, and when being sent on other-end, then need the conversion processing of picture being carried out to similar encryption, also be in step S100, answer rgb value to carry out XOR by the rgb value of each pixel in picture to be sent and the current selected Color pair of user in transmitting terminal, obtain in transmission after XOR image data, instead of directly former image data is sent to other-end.Even if other-end has intercepted and captured XOR image data, the picture to be sent that the display XOR image data that also cannot reduce is corresponding, has effectively raised picture and has shared security.
Step S200, receiving terminal receive described XOR image data, and answer rgb value to carry out XOR the rgb value of each pixel in XOR image data and described current selected Color pair, obtain the picture to be sent after reducing, and show.
After receiving terminal receives described XOR image data, Show Picture if need reduce, then also need obtain described current selected Color pair from transmitting terminal and answer rgb value, and answer rgb value to carry out XOR to reduce image data the rgb value of each pixel in XOR image data and described current selected Color pair.
Visible, carry out first time XOR to be in the step s 100 equivalent to be encrypted picture to be sent, carry out second time XOR in step s 200 and be equivalent to the reduction of XOR picture decrypt data, exactly because add said process, picture is shared and transmits safer.
Choose current selected Color pair to answer rgb value to do intermediate value to carry out XOR to image data to be sent in embodiments of the invention, but current selected Color pair answers rgb value can be replaced by other data in the concrete process implemented, as 3 numerals that user inputs arbitrarily, or 3 symbols that user inputs arbitrarily, or 3 letters inputting arbitrarily of user etc., as long as character or the character string of 3 groups of binary numbers can be converted to.
Obviously, answer rgb value when receiving terminal does not receive described current selected Color pair in step s 200, then carry out picture display according to XOR image data.Namely when current selected Color pair does not answer rgb value to be sent to receiving terminal by transmitting terminal, receiving terminal then cannot reduce XOR image data, and can only directly show according to XOR image data.Therefore do not know current selected Color pair described XOR image data of having answered third party's terminal of rgb value to intercept and capture, also cannot reduce this XOR image data.
Further, in described step S100, the idiographic flow that original image data carry out XOR process is comprised:
Step S101, transmitting terminal send instruction to the picture of user and detect in real time, when detecting that picture sends instruction, then obtain the rgb value of each pixel in picture to be sent;
Step S102, the rgb value of each pixel changed into corresponding binary value, obtain binarization rgb value;
Step S103, answer the binary value of rgb value to carry out XOR binarization rgb value and current selected Color pair, obtain XOR image data;
Step S104, rgb value is answered to be sent to receiving terminal described XOR image data and current selected Color pair.
In order to the clearer implementation procedure understanding step S101-S104, illustrate below by a specific embodiment.Such as, the mobile terminal b that user a operating mobile terminal a need hold to b user sends picture 1, performs following steps successively:
The rgb format data of each pixel in step 1, acquisition picture 1, that is:
Px[1,1]、Px[1,2]、Px[1,3]、……、Px[1,M-1]、Px[1,M]，
Px[2,1]、Px[2,2]、Px[2,3]、……、Px[2,M-1]、Px[2,M]，
Px[3,1]、Px[3,2]、Px[3,3]、……、Px[3,M-1]、Px[3,M]，
……，
Px[N-1,1]、Px[N-1,2]、Px[N-1,3]、……、Px[N-1,M-1]、Px[N-1,M]，
Px[N,1]、Px[N,2]、Px[N,3]、……、Px[N,M-1]、Px[N,M]；
Wherein, this dimension of picture size is the view data that N*M, Px [i, j] to represent in picture the rgb format of the pixel of the i-th row jth row, i=1,2,3 ..., N, j=1,2,3 ..., M; M and N is positive integer.
Step 2, user a select a kind of color on mobile terminal a, and the RGB data that this Color pair is answered is D1.
Step 3, the rgb value of each pixel in this picture and D1 being carried out XOR (operational symbol is XOR), to obtain new view data as follows:
Py[1,1]、Py[1,2]、Py[1,3]、……、Py[1,M-1]、Py[1,M]，
Py[2,1]、Py[2,2]、Py[2,3]、……、Py[2,M-1]、Py[2,M]，
Py[3,1]、Py[3,2]、Py[3,3]、……、Py[3,M-1]、Py[3,M]，
……，
Py[N-1,1]、Py[N-1,2]、Py[N-1,3]、……、Py[N-1,M-1]、Py[N-1,M]，
Py[N,1]、Py[N,2]、Py[N,3]、……、Py[N,M-1]、Py[N,M]；
Wherein, Py [i, j]=Px [i, j] XORD1; For XOR, specifically also need the step comprised below:
1) convert the rgb image data Px [i, j] of a pixel to binary representation, also convert D1 to binary representation;
2) perform Px [i, j] XORD1 and obtain Py [i, j].

Step 4, the view data obtained in step 3 is shared to mobile terminal b;
Further, in described step S200, the idiographic flow that XOR image data carries out reduction treatment is comprised:
Step S201, receiving terminal receive described XOR image data and described current selected Color pair answers rgb value;
Step S202, the binary value that binary value corresponding for the rgb value of each pixel in XOR image data and described current selected Color pair answer rgb value corresponding is carried out XOR, obtain the picture corresponding data to be sent after reducing;
Step S203, receiving terminal carry out picture display according to the picture corresponding data to be sent after reduction.
Concrete, the image data that mobile terminal b mobile terminal receive a sends, and it is as follows to reduce the flow process of picture:
Color corresponding for D1 is presented in one piece of region on screen by step 5, mobile phone users a, and namely in this region, the color of all pixels is all D1.
Step 6, mobile phone users b start the color that camera acquisition mobile phone users a shows on screen, thus obtain the rgb format view data of D1.
Step 7, Py [i, j] and D1 are performed XOR obtain Px [i, j]; For XOR, specifically also need the step comprised below:
1) convert the rgb image data Py [i, j] of a pixel to binary representation, also convert D1 to binary representation;
2), perform Py [i, j] XORD1 and obtain Px [i, j];
Such as, Py [5,6] is expressed as scale-of-two is 11111111,00000000,11111111; It is 00000000,00000000,11111111 that D1 is expressed as scale-of-two; Obtaining Px [5,6] after both being performed XOR Py [5,6] XORD1 is 11111111,00000000,00000000, achieves the reduction to picture 1.Visible, picture safe sharing implementation method of the present invention, ensure that picture is in the data security shared and in transmitting procedure.
