1 dtmf code table of table
In the disclosure, automatic by client by sending relevant identifying code via dtmf signal in conversing in verification
It identifies the identifying code in dtmf signal, and transmits relevant verification information, be automatically completed entire verification process.
It describes according to an embodiment of the present disclosure to test for carrying out client automatically based on dtmf signal below with reference to Fig. 1
The schematic diagram of the method 100 of card.
In step S101, client sends checking request to verification code system, which includes and client phase
The time is initiated in corresponding phone number and verification.When client is initiated to verify, user needs to fill in cell-phone number by client
Code.Checking request can be initiated from client to verification code system with Json formats.The verification initiation time can be as accurate as
Millisecond.
In step S102, verification code system receives checking request from client, and according to the cell-phone number in checking request
The first identifying code of time generation is initiated in code and verification.What the first identifying code can be randomly generated.First identifying code may include 6
A digit order number, for example, 123456.
In step S103, verification code system sends clawback request to the system that calls back, and clawback request includes and client
Hold corresponding phone number and the first identifying code.Clawback request can be with Json formats from verification code system to calling back
What system was initiated.
In step S104, the system that calls back receives clawback request from verification code system, and is asked in response to the clawback,
Dtmf signal is generated according to the first identifying code.Step S104 may include:It is generated according to the first identifying code using dtmf code table
Dtmf signal, wherein DMTF coding schedules include 16 codings, each coding is by a high-frequency signal and a low frequency signal group
At as shown in table 1.
Dtmf signal a length of 10 seconds audio signals when can be.For example, verification code system is according to first generated at random
Identifying code (including 6 digit order numbers) and a stop bits utilize the coding schedule of table 1 to generate a length of 10 seconds audios when a segment signal,
It is 1 second a length of when each digit order number in wherein the first identifying code, and have between each digit order number between 0.5 second blank time
Every for addition " # " as stop bits, stop bits duration is also 1 second, and is tied after the last one digit order number of the first identifying code
Also there is 0.5 second blank spaces between the last one digit order number of Shu Weiyu, therefore the dtmf signal is 10 seconds total.In an example
In, when the first identifying code is such as 123456, the dtmf signal generated for the first digit position " 1 " of the first identifying code is
The superposition of the signal of one 0.5 second 697Hz and the signal of 0.5 second 1209Hz, first digit position " 1 " and second
There to be 0.5 second blank interval between digit order number " 2 ", and so on.
In step S105, the system that calls back sends the pond that calls back to verification code system.
In step S106, verification code system calls back pond, to select from the pond that calls back from the system reception that calls back
(for example, randomly) callback number, and phone number, the first identifying code and callback number are stored in association with local number
According in library.
In step S107 and step S108, verification code system is for example by ICP/IP protocol respectively to client and clawback electricity
Telephone system sends selected callback number.Callback number can be with Json formats from verification code system to client and clawback
What telephone system was sent.
In step S109, the system that calls back is received by verification code system from verification code system and is selected from the pond that calls back
Callback number, and with the callback number received to client initiate telephone redialing, which includes the DTMF
Signal.
In step S110, in client after verification code system receives callback number, client begins listening for the clawback
Number, and when client receives the telephone redialing initiated with the callback number from the system of calling back, analyze the electricity
The dtmf signal for including in words clawback is to generate the second identifying code.Second identifying code may include 6 digit order numbers.Step S110 can
To include:Using dtmf code table analysis dtmf signal to generate the second identifying code, wherein DMTF coding schedules include 16 volumes
Code, each coding are made of a high-frequency signal and a low frequency signal.
For example, the when a length of 10 seconds sound listened to was carried out cutting to obtain multiple audios by client with every 0.5 second
Segment analyzes the sound frequency of each audio fragment, then the coding schedule of the table of comparisons 1, is converted into corresponding second identifying code.It answers
When it is noted that when being converted to stop bits " # " according to a certain audio fragment, analysis terminates, and will be before stop bits
To set of data bits be combined into the second identifying code.In one example, if the sound clip got be one 0.5 second
The signal of the signal of 697Hz and 0.5 second 1209Hz, then client analysis obtain the respective counts word bit in the second identifying code
For " 1 ", and so on.
In step S111, client sends verification information to verification code system, which includes opposite with client
Phone number, callback number and the second identifying code answered.Verification information can be for example by ICP/IP protocol with Json formats
It sends.
In step S112, verification code system receives verification information from client, according in verification information phone number and
Callback number determines associated first identifying code stored in local data base, when the first identifying code is identical as the second identifying code
When, client is determined by verification, and when the first identifying code and the second identifying code difference, determines that client validation fails.
In one implementation, client can receive the optional inventory of identifying code that verification code system issues, the verification
It is stored with multiple identifying codes and number corresponding with each identifying code in the optional inventory of code.Client determines that identifying code is optional
Number corresponding with the second identifying code of generation in inventory, and client sends verification information to verification code system, and this is tested
It includes phone number corresponding with client, callback number and number corresponding with the second identifying code to demonstrate,prove information.Identifying code
System from client receive verification information, according in verification information phone number and callback number determine in local data base and deposit
Associated first identifying code of storage, and the second verification corresponding with number in the optional inventory of identifying code is determined according to number
Code determines client by verification when the first identifying code is identical as the second identifying code, and when the first identifying code is tested with second
When demonstrate,proving code difference, determine that client validation fails.
The message mechanism that the disclosure is realized based on ICP/IP protocol passes through the system of calling back, verification code system and client
Information between end and data interaction parse the dtmf signal in calling back, and automatically identify identifying code, and return
To verification code system, entire verification process is completed.
