" described transmission smart mobile phone A can point out user by text information " how do you do? " encrypted transmission, when the encryption transmission instruction of user's input being detected, described transmission smart mobile phone A by show screen display this paper information " how do you do? " carry out sectional drawing, described text message is converted into message bit pattern.Described transmission smart mobile phone A detects after user's encrypted instruction, extract and receive the facility information of smart mobile phone B or extract default protocol information, the facility information of described smart mobile phone B is for example SIM card information, described default protocol information is finger print information or voice messaging for example, and described voice example information is as being the Chinese speeches such as Chinese mandarin, country dialect or comprising the foreign language voice such as English, French, Japanese; In the present embodiment, extract the SIM card information of described smart mobile phone B, and according to the Information generation embedded key extracting; Described transmission smart mobile phone A is according to the encrypted instruction of user's input, and according to the embedded key detecting, generating watermark embeds algorithm, according to prompting, from mobile phone, choose at random a pictures or choose a default picture, described message bit pattern is embedded in picture according to the watermarking algorithm of least significant bit; The capacity of described picture, much larger than the capacity of described message bit pattern, while making described message bit pattern embed in picture, can not be differentiated by naked eyes; User, according to the prompting of described transmission smart mobile phone A, is confirmed whether to send the image information of this encryption, when the instruction that user confirms to send being detected, by embedding the picture of stating to some extent message bit pattern, sends to described reception smart mobile phone B.
Described reception smart mobile phone B prompting receives the enciphered message sending over from described transmission smart mobile phone A, on display screen, point out user whether to receive this enciphered message, user being detected inputs after reception instruction, described reception smart mobile phone B receives and embeds the picture that has message bit pattern, when user wants to check the content of text of described encrypted information, according to the prompting of display screen, selection has the picture of message bit pattern to be decrypted to described embedding, described reception smart mobile phone B is according to decryption instructions, the SIM card Information generation that detects described reception smart mobile phone B extracts key, described reception smart mobile phone B is according to decryption instructions, utilize and extract the watermark extracting algorithm that key generates least significant bit, the message bit pattern embedding in described picture is extracted, and be translated into text message " how do you do? ", and it is shown.
In sum, the beneficial effect that a kind of electric terminal that the present invention proposes and SMS encryption decryption method thereof have is:
Utilize the watermarking inset and distill algorithm of least significant bit, the text message of transmission is converted in message bit pattern embedding picture and is sent, the fail safe of guarantee information;
Utilize targeted customer's facility information or default protocol information that note is encrypted and is deciphered, in the time of can guaranteeing to be kidnapped by third party in note transmitting procedure, safety that still can guarantee information;
Utilize default protocol information that note is encrypted and is deciphered, not only can guarantee the fail safe in note transmitting procedure, can also prevent that the information that mobile phone is stored in while losing in equipment from exposing.
So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
