Different data receiving terminal corresponding speckle image is set, and establish pair of the image identification and receiving terminal mark of speckle image
It should be related to.It can be identified according to the receiving terminal of data receiver when transmission data to obtain corresponding speckle image,
And it is encrypted according to the speckle image of acquisition.
Speckle image is then obtained to can specifically include：The intended recipient end mark of data receiver is obtained, and obtains data
Pre-stored intended recipient end identifies corresponding first speckle image in transmitting terminal.Receiving terminal mark refers to for distinguishing difference
The unique identification of data receiver, such as when an electronic equipment is to another electronic equipment transmission data, the reception
End mark can be the equipment identity for the electronic equipment for receiving data.If being passed between an electronic equipment internal disparate modules

It can be decrypted according to the first speckle image received.
Step 306, data to be transmitted is encrypted according to the first speckle image, obtains encryption data.
It is understood that the first speckle image obtained is made of a two-dimensional picture element matrix, each picture
Vegetarian refreshments has corresponding pixel value.Since the first speckle image that electronic equipment obtains has uniqueness, so the first speckle pattern
As itself can serve as an encrypted key, for data to be transmitted is encrypted.According to the first speckle image
Data to be transmitted is encrypted, so that it may to obtain encryption data.For example, data to be transmitted can be a figure to be transmitted
First speckle image then can directly be overlapped with image to be transmitted, obtains an encrypted image by picture.It can also will be to be passed
The corresponding picture element matrix of defeated image picture element matrix corresponding with the first speckle image carries out product calculation, obtains encrypted image.
Some in the first speckle image or the corresponding pixel value of multiple pixels can be gone as encryption key, to data to be transmitted into
Row encryption, specific Encryption Algorithm is the present embodiment does not limit.
Step 308, encryption data is sent to data receiver.
Encryption data is obtained after encryption, then encryption data can be sent to data receiver by data sending terminal.If
Data sending terminal is encrypted according to the speckle image that prestores, then data receiver can also prestore an identical speckle pattern
Picture, then data receiver is after receiving big encryption data, the speckle image that can be prestored according to this is decrypted.If
Data sending terminal is encrypted according to the speckle image obtained in real time, then data sending terminal can add sending
When ciphertext data, the speckle image of acquisition is sent jointly into data receiver, data receiver receives encryption data again
It can be decrypted afterwards according to the speckle image received.In order to improve the safety of data, data sending terminal can be with
Speckle image and encryption data are subjected to timesharing transmission, be trapped simultaneously to avoid speckle image and encryption data and cause data

Tag splice receiving end is identified to be compared with the receiving terminal mark received in list.If intended recipient end identifies and receives connecing in list
Receiving end mark matches, then illustrates that the intended recipient end identifies corresponding data receiver and received speckle image, just do not have to again
Speckle image is sent to the data receiver.On the contrary, illustrating that the intended recipient end identifies corresponding data receiver and do not connect
Speckle image was received, then when sending encryption data, needs speckle image sending jointly to data receiver.Specifically
Including：
Step 402, the intended recipient end mark of data receiver is obtained.
Step 404, if intended recipient end mark matches with the receiving terminal mark received in list, encryption data is sent out
It is sent to data receiver, receives the receiving terminal mark in list for uniquely indicating a data receiver that store speckle image
End.
Step 406, if intended recipient end mark is mismatched with the receiving terminal mark received in list, by encryption data and
First speckle image is sent to data receiver.
In embodiment provided by the present application, if intended recipient end mark with the receiving terminal mark that receives in list not
Match, then illustrates that intended recipient end identifies the speckle image for not having storage for decryption in corresponding data receiver, then data are sent out
Sending end can obtain speckle image in real time when encryption, can also obtain the speckle image to prestore.It specifically, can be according to electricity
