Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
In embodiments of the present invention, in communication process, after the calling subscriber hears the prompt tone of input password, select first the cryptoguard item corresponding with this password type, read the password of storing in the described cryptoguard item, and add password end mark, generating cipher position in the position, end of described password; Again described password position is processed, generate the dtmf signal corresponding with described password position, and the generation of the shielding keypad tone corresponding with described dtmf signal.
Below in conjunction with specific embodiment realization of the present invention is described in detail:
Embodiment one
Fig. 1 shows the realization flow figure of the cipher-code input method that the embodiment of the invention one provides, and for convenience of explanation, only shows the part relevant with the embodiment of the invention, and details are as follows:
In step S101, in communication process, receive the prompting input code signal of called party terminal transmission and play to the calling subscriber.
In embodiments of the present invention, in the process of calling subscriber and called subscriber's conversation, the calling subscriber hears the voice signal of prompting input password.Wherein, the voice signal of this prompting input password is that called party terminal sends to the employed portable terminal of calling subscriber, and by this mobile terminal playing to the calling subscriber's.
In step S102, receive the cryptoguard item of selecting, described cryptoguard item is corresponding one by one with the type of the password that will input.
In embodiments of the present invention, the difference of the business of handling according to the calling subscriber, the calling subscriber can hear the password that input is dissimilar, such as, when the user handles telephone banking, may require the input inquiry password, during with telecom operators' customer service conversation, may require to input service password.In a word, what the calling subscriber handled is professional different, and the type of the password of prompting input can be different.Therefore; the calling subscriber at first needs according to the type of the business that will handle dissimilar password to be set in portable terminal; and the password that those are dissimilar is saved in default cryptoguard item or the newly-built cryptoguard item; wherein, store one type password in a cryptoguard item.And after this password was preserved, the cryptoguard item that this password is corresponding can only be deleted, can not be checked or revise.
After the user hears that the voice signal of password is inputted in the prompting of mobile terminal playing; in conversation arranges; select and click the cryptoguard item that stores this type password, the type of the password of storing in this cryptoguard item is identical with the type of the password that the needs that the user hears are inputted.
In step S103, read the password of storing in the described cryptoguard item, and add password end mark, generating cipher position in the position, end of described password.
In embodiments of the present invention; after the employed portable terminal of calling subscriber receives the cryptoguard item of user selection; read the password of storing in this cryptoguard item; and add password end mark " # " number in the end position of this password; generate a password position, be equivalent to the calling subscriber and inputted a string password position by the keyboard of portable terminal.
In step S104, described password position is processed, generate the dtmf signal corresponding with described password position, and the generation of the shielding keypad tone corresponding with described dtmf signal.
In embodiments of the present invention, behind the password position that is equivalent to input by the keyboard of portable terminal by step S103 generation, the employed portable terminal of calling subscriber calls corresponding processing function, this password position is processed, generate the dtmf signal corresponding with this password position, because the dtmf signal that produces can produce the keypad tone that is similar to by keyboard input password position, in order not snatched password by analyzing this keypad tone by illegal molecule, so also need to after converting the password position to dtmf signal, shield the keypad tone that this dtmf signal produces.
As a preferred embodiment of the present invention, in execution in step S104, all right execution in step S105:
In step S105, in the Password Input frame of display screen, show a string random digit.
In embodiments of the present invention, show in the Password Input frame of display screen that a string random digit is deceptive information, with user cipher without any relation, on the one hand be in order to point out the calling subscriber to input password, also be in order to play fascination lawless person's purpose on the other hand.
As another preferred embodiment of the present invention, lose in order to prevent the employed portable terminal of calling subscriber, cause the lawless person to utilize this call function of this portable terminal, just can handle corresponding business, the embodiment of the invention can also comprise step S106:
In step S106, cipher protection function is set, before conversing with called party terminal or before the cryptoguard item that reception is selected, receive the described cipher protection function of opening of input, open described cipher protection function; With the called party terminal end of conversation after, receive the described cipher protection function of closing of input, close described cipher protection function.
In embodiments of the present invention, the calling subscriber arranges cipher protection function in can arranging in the conversation of use portable terminal, and this cipher protection function is illustrated in the communication process, the password that calling mobile terminal can reading pre-stored.Opening this cipher protection function needs the user password password, and this user password password is that user oneself arranges.After closing this cipher protection function, even taking the portable terminal of calling subscriber's use, others also can't in conversation, call pre-stored password.
Of particular note, step S106 carries out after step S105, and opening cipher protection function can be to carry out before step S101, also can be to carry out before S102; Closing cipher protection function is to carry out after step S105.Arranging of cipher protection function can be carried out before step S101, also can carry out before step S102.
The embodiment of the invention is in communication process, after the calling subscriber hears the prompt tone of input password, select first the cryptoguard item corresponding with this password type, read the password of storing in the described cryptoguard item, and add password end mark, generating cipher position in the position, end of described password; Again described password position is processed, generate the dtmf signal corresponding with described password position, and the generation of the shielding keypad tone corresponding with described dtmf signal.In reducing communication process, in the input complexity of required password, also solve the problem of cryptoguard, improved the fail safe of the sensitive traffic information such as telephone bank.
