Embodiment
With reference now to accompanying drawing, describe embodiments of the invention, similar element numbers represents similar element in the accompanying drawing.As mentioned above, encryption call method of the present invention at first arranges amplification ratio n and obscures sound wave shape, obtain afterwards the arbitrary frequency range waveform that needs the call voice of encrypting and extract described call voice, then arbitrary described frequency range waveform being multiply by described amplification ratio n decomposes waveform and obscures sound wave shape and insert described decomposition waveform with the formation encrypted speech described to form encrypted speech and/or will arbitrary described frequency range waveform to be decomposed into the T section, T 〉=2 wherein, thereby realized the encryption to call voice, guaranteed the information security of both call sides and improved user's experience.
Please refer to Fig. 1, described the flow chart of encryption call method one embodiment of the present invention.As shown in Figure 1, may further comprise the steps:
Step S101 sets in advance amplification ratio n and obscures sound wave shape; Wherein amplification ratio n is the arbitrary value except 0, and n satisfies n in the present embodiment〉Fmax/Fmin, wherein Fmax is that peak frequency, the Fmin of voice are the minimum frequency of voice, obscures the waveform that sound wave shape is Set arbitrarily;
Step S102 judges whether call voice is encrypted, if, execution in step S104 then, otherwise, execution in step S103; Wherein, if call voice is encrypted, the dialog context that then moment after determining to be encrypted is begun is encrypted processing, only when running into the content that needs encryption, just start encryption function by the user, rather than all dialog contexts have been encrypted automatically, thereby improved data transmission efficiency and saved resource;
Step S103 is not encrypted processing;
Step S104 obtains the arbitrary frequency range waveform that needs the call voice of encrypting and extract described call voice; As: the frequency range corresponding to call voice of need encrypting is 100-800Hz, then can extract 100-200Hz, 150-800Hz or 100-800Hz etc. and be included in arbitrarily arbitrary frequency range waveform in the 100-800Hz scope;
Step S105 multiply by amplification ratio n with the arbitrary frequency range waveform that extracts and decomposes waveform and will obscure sound wave shape and insert and decompose waveform to form encrypted speech, wherein T 〉=2 to form encrypted speech and/or arbitrary frequency range waveform is decomposed into the T section; Be specially, the amplitude of frequency range waveform and/or frequency be multiply by amplification ratio n to form encrypted speech;
Concrete, can only carry out following encryption to arbitrary frequency range waveform and obtain encrypted speech, as: amplification ratio n=2*Fmax/Fmin is set, and it no longer is human sound that the frequency of arbitrary frequency range waveform be multiply by the encrypted speech that obtains after the amplification ratio n, thereby has guaranteed conversation safety; Perhaps the amplitude with arbitrary frequency range waveform multiply by amplification ratio n, or frequency and the amplitude of arbitrary frequency range waveform be multiply by amplification ratio n simultaneously; Also can only carry out following encryption to arbitrary frequency range waveform, as: arbitrary frequency range waveform is decomposed into T(such as T=4) section decomposition waveform, then will obscure sound wave shape inserts in these the 4 sections decomposition waveforms, wherein every section decomposition waveform comprises m2 unit waveform, m2 〉=1, arbitrary frequency range waveform comprises m1 unit waveform, then m1 and m2 satisfy following relation: m1=T*m2, concrete will obscure sound wave shape and insert the position of decomposing waveform and be: all insert at every section anterior locations of decomposing waveform and back location and obscure sound wave shape, namely insert before first unit waveform that decomposes waveform and after last unit waveform and obscure sound wave shape, perhaps between any two unit waveforms of every section decomposition waveform, insert and obscure sound wave shape, as: every section is decomposed waveform and comprises 3 unit waveforms, then can decompose to insert between first unit waveform in the waveform and second the unit waveform at every section and obscure sound wave shape, thereby realize the encryption of voice is obtained encrypted speech; Certainly, thereby can also carry out simultaneously the above two kinds to arbitrary frequency range waveform operates and obtains encrypted speech, as: at first the amplitude of arbitrary frequency range waveform be multiply by amplification ratio n, afterwards arbitrary described frequency range waveform being decomposed into the T section decomposes waveform and will obscure sound wave shape insertion decomposition waveform to form encrypted speech, thereby encrypted speech has changed dialog context, only after deciphering accordingly, just can obtain correct dialog context, guarantee conversation safety;
Step S106 finishes ciphering process one time thereby encrypted speech is sent to the conversation opposite end, and the encrypted speech that reception conversation opposite end sends over and the process that is decrypted are the inverse process corresponding with ciphering process.
Please refer to Fig. 2, described the structured flowchart of speech scrambling terminal 100 1 embodiment of the present invention.
As shown in Figure 2, speech scrambling terminal 100 comprises module 10, voice acquisition module 11 and encrypting module 12 is set.Module 10 is set to be used for setting in advance amplification ratio n and obscuring sound wave shape; Voice acquisition module 11 is used for obtaining the arbitrary frequency range waveform that needs the call voice of encrypting and extract described call voice; Encrypting module 12 with module 10 and voice acquisition module 11 are set are connected, are used for will arbitrary described frequency range waveform to multiply by described amplification ratio n and decompose waveform and also obscure sound wave shape and insert described decomposition waveform with formation encrypted speech, wherein T 〉=2 described to form encrypted speech and/or will arbitrary described frequency range waveform to be decomposed into the T section.Concrete, amplification ratio n satisfies n〉Fmax/Fmin, wherein Fmax is that peak frequency, the Fmin of voice are the minimum frequency of voice; Wherein will " arbitrary described frequency range waveform multiply by amplification ratio n to form encrypted speech " can be that amplitude with arbitrary described frequency range waveform multiply by amplification ratio n, frequency multiply by amplification ratio n or amplitude and frequency and multiply by simultaneously amplification ratio n; Wherein arbitrary frequency range waveform comprises m1 unit waveform, each section decomposes waveform and comprises m2 unit waveform, and m1 〉=2, m2 〉=1, the position that will obscure sound wave shape insertion decomposition waveform in the encrypting module 12 is: before first unit waveform of decomposition waveform, after last unit waveform or between any two unit waveforms.
As can be seen from the above description, speech scrambling terminal 100 of the present invention sets in advance amplification ratio n and obscures sound wave shape by module 10 is set, obtain the arbitrary frequency range waveform that needs the call voice of encrypting and extract call voice by voice acquisition module 11 again, call by encrypting module 12 at last and module 10 is set and 11 pairs of call voices of voice acquisition module are encrypted, thereby realized the purpose of speech scrambling voice, guaranteed the information security of both call sides and improved user's experience.
Above invention has been described in conjunction with most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain various modification, equivalent combinations of carrying out according to essence of the present invention.
