Fig. 2 is the structured flowchart of call encryption terminal one embodiment of the present invention.
Embodiment
With reference now to accompanying drawing, describe embodiments of the invention, element numbers similar in accompanying drawing represents similar element.As mentioned above, first encryption call method of the present invention arranges amplification ratio n and obscures sound wave shape, obtain the call voice any frequency range waveform extracting described call voice that need encryption afterwards, then arbitrary described frequency range waveform is multiplied by described amplification ratio n decompose waveform to form encrypted speech and/or arbitrary described frequency range waveform to be decomposed into T section and obscure sound wave shape insert described decomposition waveform to form encrypted speech by described, wherein T >=2, thus the encryption achieved call voice, ensure that the information security of both call sides and improve Consumer's Experience.
Please refer to Fig. 1, describe the flow chart of encryption call method one embodiment of the present invention.As shown in Figure 1, comprise the following steps:
Step S101, pre-sets amplification ratio n and obscures sound wave shape; Wherein amplification ratio n is the arbitrary value except 0, and n meets n > Fmax/Fmin in the present embodiment, and wherein Fmax is the peak frequency of voice, Fmin is the minimum frequency of voice, obscures the waveform that sound wave shape is setting arbitrarily;
Step S102, judges whether to be encrypted call voice, if so, then performs step S104, otherwise, perform step S103; Wherein, if be encrypted call voice, then the dialog context from the moment after determining to be encrypted is encrypted, only just start encryption function by user when running into the content needing encryption, instead of all dialog contexts are encrypted automatically, thus improve data transmission efficiency and save resource;
Step S103, is not encrypted;
Step S104, obtains the call voice any frequency range waveform extracting described call voice that need encryption; As: frequency range corresponding to call voice needing encryption is 100-800Hz, then can extract 100-200Hz, 150-800Hz or 100-800Hz etc. and be included in arbitrarily any frequency range waveform within the scope of 100-800Hz;
Step S105, is multiplied by amplification ratio n and decomposes waveform to form encrypted speech and/or any frequency range waveform to be decomposed into T section and will obscure sound wave shape insertion decomposition waveform to form encrypted speech, wherein T >=2 by any frequency range waveform of extraction; Be specially, the amplitude of frequency range waveform and/or frequency be multiplied by amplification ratio n to form encrypted speech;
Concrete, can only carry out following encryption to any frequency range waveform and obtain encrypted speech, as: arrange amplification ratio n=2*Fmax/Fmin, the encrypted speech obtained after the frequency of any frequency range waveform is multiplied by amplification ratio n is no longer the sound of the mankind, thus ensure that call safety, or the amplitude of any frequency range waveform is multiplied by amplification ratio n, or the frequency of any frequency range waveform and amplitude are multiplied by amplification ratio n simultaneously, also only following encryption can be carried out to any frequency range waveform, as: any frequency range waveform is decomposed into T (as T=4) section and decomposes waveform, then will obscure sound wave shape inserts in these 4 sections decomposition waveforms, wherein every section of decomposition waveform comprises m2 unit waveform, m2 >=1, any frequency range waveform comprises m1 unit waveform, then m1 and m2 meets following relation: m1=T*m2, concrete insert the position of decomposing waveform by obscuring sound wave shape be: all insert in every section of anterior locations of decomposing waveform and back location and obscure sound wave shape, namely insert before first the unit waveform decomposing waveform and after last unit waveform and obscure sound wave shape, or insert between any two unit waveforms that every section is decomposed waveform 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 waveform and second unit waveform at every section and obscure sound wave shape, realize the encryption of voice thus obtain encrypted speech, certainly, the above two kinds can also be carried out to any frequency range waveform operate thus obtain encrypted speech simultaneously, as: first amplification ratio n is multiplied by the amplitude of any frequency range waveform, afterwards arbitrary described frequency range waveform is decomposed into T section decompose waveform and sound wave shape insertion decomposition waveform will be obscured to form encrypted speech, thus encrypted speech changes dialog context, only after deciphering accordingly, just can obtain correct dialog context, ensure that call safety,
Step S106, is sent to call opposite end thus complete a ciphering process by encrypted speech, receive encrypted speech that call opposite end sends over and the process be decrypted is the inverse process corresponding with ciphering process.
Please refer to Fig. 2, describe the structured flowchart of call encryption terminal 100 1 embodiment of the present invention.
As shown in Figure 2, call encryption terminal 100 comprises and arranges module 10, voice acquisition module 11 and encrypting module 12.Module 10 is set for pre-setting amplification ratio n and obscuring sound wave shape; Voice acquisition module 11 is for obtaining the call voice that need encrypt and extracting any frequency range waveform of described call voice; Encrypting module 12 with module 10 is set and voice acquisition module 11 is connected, decompose waveform for arbitrary described frequency range waveform being multiplied by described amplification ratio n to form encrypted speech and/or arbitrary described frequency range waveform to be decomposed into T section and obscure sound wave shape insert described decomposition waveform to form encrypted speech, wherein T >=2 by described.Concrete, amplification ratio n meets n > Fmax/Fmin, and wherein Fmax is the peak frequency of voice, Fmin is the minimum frequency of voice; By " arbitrary described frequency range waveform is multiplied by amplification ratio n to form encrypted speech " can be wherein the amplitude of arbitrary described frequency range waveform is multiplied by amplification ratio n, frequency is multiplied by amplification ratio n or amplitude and frequency and is multiplied by amplification ratio n simultaneously; Wherein any frequency range waveform comprises m1 unit waveform, every lst-stage precipitation waveform comprises m2 unit waveform, and m1 >=2, m2 >=1, in encrypting module 12 by the position of obscuring sound wave shape insertion decomposition waveform is: before decomposing first unit waveform of waveform, after last unit waveform or between any two unit waveforms.
As can be seen from the above description, call encryption terminal 100 of the present invention pre-sets amplification ratio n by arranging module 10 and obscures sound wave shape, obtain by voice acquisition module 11 call voice that need encrypt again and extract any frequency range waveform of call voice, call finally by encrypting module 12 and module 10 is set and voice acquisition module 11 pairs of call voices are encrypted, thus achieve the object of speech scrambling voice, ensure that the information security of both call sides and improve Consumer's Experience.
More than in conjunction with most preferred embodiment, invention has been described, but the present invention is not limited to the embodiment of above announcement, and should contain various carry out according to essence of the present invention amendment, equivalent combinations.
