Safety, reliability.It addition, all users of having identify all can making of uniqueness and authentication terminal equipment uniqueness identity characteristic
For forming the cryptographic key factor of key.
As the further improvement of technical scheme, described encryption and decryption authentication password includes character, fingerprint, iris image, institute
State encryption and decryption authentication password by preserving to the data base of intelligent terminal after encryption.
As the further improvement of technical scheme, described intelligent terminal's fix information includes intelligent terminal's IMEI code, intelligence
Terminal SN, described encryption chip fix information includes that the inside that encryption chip SN, encryption chip SN are encryption chip is compiled
Code, every chips has unique No. SN and be made up of 16 bit digital, and the IMEI code of intelligent terminal is added 1 bit check by 14 bit digital
Code composition.
In the present embodiment, reference Fig. 2, Fig. 2 is the tool encrypting photo in the present invention in a kind of photo encipher-decipher method
Body embodiment flow chart of steps, time actually used, makes the photo encryption system being obtained by the present invention run with intelligence eventually
On the operating system of end, before entering photo encryption system, need to arrange the encryption and decryption authentication password of photo encryption system, institute
State encryption and decryption authentication password and carry out safety certification for the user that request is entered photo encryption system, when certification is by just entering
Enter photo encryption system, encryption photo is carried out feature operation and management.Then, interface interchange is passed through on photo encryption system backstage
Obtain intelligent terminal's IMEI code, encryption chip SN, and judge whether described intelligent terminal's IMEI code, encryption chip SN code have
Effect, when intelligent terminal's IMEI code, encryption chip SN are invalid, arrange the failure of encryption and decryption authentication password, otherwise arranges encryption and decryption

Cheng Tu, is stored in original photo in the file of temporal cache, encryption chip according to key by the caching in the file of temporal cache
Photo after photo is encrypted preserves to terminal memory.After photo has been encrypted, read the closing tag of encryption photo, sentence
Disconnected photo encryption is the most successful, if encrypting successfully, will delete temporal cache file, will photograph successful to unencryption if unsuccessful
Sheet is encrypted again, encrypts successful photo and can be saved in photo encryption system and normally show preview.Encryption photo makes
Preserve by ciphertext, will not normally be read and show in the picture library of intelligent terminal operation system, need by export function, will
Encryption photo is derived to (derivation process is exactly a decrypting process) in intelligent terminal operation system, could normal preview show.
It is the specific embodiment step stream deciphering photo in the present invention in a kind of photo encipher-decipher method with reference to Fig. 3, Fig. 3
Cheng Tu, is stored in encryption photo in the file of temporal cache, encryption chip according to key by the caching in the file of temporal cache
Photo after photo is decrypted preserves to terminal memory.After photo has been deciphered, read the closing tag of deciphering photo, sentence
Disconnected photo deciphering is the most successful, if successful decryption, will delete temporal cache file, if unsuccessful, then to non-successful decryption
Photo re-starts deciphering, and the photo of successful decryption preserves the picture library to intelligent terminal operation system, normally can show in picture library
Show preview.
Encryption process use cache file folder preserve encryption and decryption photo, when encryption and decryption is failed or in encryption and decryption power-off
