Based on above-mentioned mobile terminal, a kind of image encryption transmission method is present embodiments provided, Fig. 2 is according to the present invention
The flow chart of the image encryption transmission method of embodiment, as shown in Fig. 2, the process includes the following steps:
The broken of the first predetermined number negotiated in advance with receiving end is respectively cut into multiple electronic images by step S202
Piece；
The fragment is converted to string of binary characters, and each string of binary characters is encrypted by step S204, together
When mark the serial number of the fragment；
The corresponding storage of the serial number of the encrypted string of binary characters and the fragment is arrived database by step S206
In；
Step S208 transmits the data extracted from the database, wherein in the data to the receiving end in batches
Carry out-of-order multiple strings of binary characters.
By step S202 to S208, first negotiated in advance with receiving end is respectively cut into multiple electronic images and is made a reservation for
The fragment of number；The fragment is converted into string of binary characters, and each string of binary characters is encrypted, is marked simultaneously
The serial number of the fragment；By the corresponding storage of the serial number of the encrypted string of binary characters and the fragment into database；
The data extracted from the database are transmitted to the receiving end in batches, wherein the multiple of random ordering are carried in the data
String of binary characters, therefore, it is poor by the safety transmitted after ciphered compressed to multiple images in the related technology to can solve
The problem of, by the way that the cutting of multiple images fragmentates, fragment is converted into string of binary characters and encrypts and upsets after sequence in batches
Transmission, improves the safety of image transmitting.
In the embodiment of the present invention, in above-mentioned steps S204, it is by the mode that each string of binary characters encrypts
It consults, can specifically include with receiving end in advance: by the number of electronic image and the serial number of the fragment to each institute

Electronic image sender installs the software tool to local computer, imports the electronic image original version for needing to transmit
This.
By every electronic image by the contour fragment for being cut transversely into both sides and arranging number, as both sides arrange this fragment number
It is 40, then electronic image will be cut into 40 fragments.Fragment is converted into string of binary characters, is arrived with AES encryption and storage
In database, while marking fragment sequence.Such as: Data Sheet Design is 3 fields, and the 1st field is electronic image number, such as
001；2nd field is electronic image fragment serial number, and such as F01, the 3rd field is the electronic image fragment binary word of encryption
Symbol, Advanced Encryption Standard (Advanced Encryption Standard, referred to as AES) Crypted password use " electronic image
The Crypted password of number+electronic image serial number ", i.e. " 001F01 ", data line every in this way is all different.
Data sequence is upset, then takes out data in batches, 100 row of every batch of or the configurable (electricity transmitted as needed
Subgraph quantity determines batch size, and avoiding batch too much causes decryption oprerations excessively cumbersome).
Data ", " separator that every batch of is taken out is spliced into a character string, using the outer layer Crypted password of configuration,
It is encrypted again with AES encryption method.
Target audience (i.e. receiving end) installs the software tool to local computer.
By multiple encrypted characters strings by batchwise transfer on line to target audience, while the software tool will be automatically by postal
Part or short message mode send outer layer Crypted password.
After target audience receives encrypted characters string, it is decrypted by inputting outer layer Crypted password.
After decryption, separates by ", " and pre-processed, the data line for being disturbed sequence can be obtained, and be stored in local data base.
By database sort, the data line of correct sequence is obtained.It is taken out in batches accordingly according still further to the number of tiles of agreement
The data line of quantity, such as arranging number of tiles is 40, then takes out by every 40 row data and reduction treatment is decrypted.
The data line that will be taken out in batches, use every row the 1st field and the splicing of the 2nd field contents as clear crytpographic key into
Row decryption, obtains the original binary character string of the 3rd field.The character string of 1 batch is subjected to image restoring, and in order
It is spliced into an electronic image, to obtain the original version of the electronic image.
