Determine the statement true and false, need to only be identified according to the user and obtain newest coding schedule, effective source of sound is decoded further according to newest coding schedule
Unanimously whether the identity information in file, the identity information for decoding acquisition is contrasted with user identifier, see, if decoding
The identity information arrived is consistent with user identifier, then can determine that the user identity currently identified decodes the user identity obtained, instead
It, then identification fails.
Step S20, inquires about presetting database, the corresponding coding rule of the user identifier is obtained, according to the coding schedule
Key obtains newest coding schedule with coding rule；
Coding rule in the present embodiment, refer in particular in effective audio files except user identifier and coding watch key in addition to,
The key messages such as identity information, check information (hereinafter referred key message) are converted to the coding rule of audio, according to the coding
Rule can obtain newest coding schedule, and it is each that identification terminal is based on key message frequency range in the effective audio files of newest coding schedule acquisition
The implication that frequency refers to, i.e. identification terminal decodes the key message part in effective audio files, hair based on the newest coding schedule
End group of making arrangements for his funeral encodes key message in the newest coding schedule.
After obtaining user identifier, inquiry identification terminal can be identified according to the user, is obtained corresponding with the user identifier
Coding rule.User will first be registered before identification in the identification terminal of identification system, typing itself letter
Breath, identification terminal distribute a coding rule for belonging to the user for it.So after user identifier is determined, you can according to this
User identifier inquires about presetting database, obtains the specific coding rule of user identifier.
Different user has different coding rules, this is in order to ensure the security of identification, if because institute is useful
There is identical coding rule at family, once then someone records effective audio files, so that it may according to general coding rule
Effective audio files are decoded, in other words can be according to coding rule personation.User identifier is corresponding with coding rule to close
System can be mapping table, and storage is in the database.
Coding rule, that is, character is converted into the correspondence of ultrasonic frequency, can be diversified forms, can directly with most
Newly organized code table overlaps or synthesizes the mode of newest coding schedule.
In one embodiment, coding rule can be a function (being called coding rule function).Then step S20
Middle the step for obtaining newest coding schedule with coding rule according to the coding watch key, can include：
Step S21, substitutes into coding rule function as input parameter using the coding watch key, obtains coding rule function
Output result；
Step S22, the output result is newest coding schedule.
Input parameter of the watch key as coding rule function will be encoded, a newest coding is exported based on coding watch key
Table.For example, newest coding schedule A is produced by function f, watch key c input function f will be encoded, obtain newest coding schedule A=f (c).
The character string that coding watch key is generated at random by transmission terminal, the character string generated at random are joined as the input of coding rule function
The output result that number finally obtains is also random, because send terminal all regenerates volume at random in identification each time
Code table key, so, the coding watch key in identification each time is all random, is largely known with last identity
In not, the coding watch key in pervious identification is all different in other words, it is caused the result is that：Because input parameter
(encoding watch key) is different, the output result of coding rule function be also it is different, i.e., newest coding schedule be it is different, so
It can ensure in identification each time, key message is different from the conversion of audio.
For example, in n-th identification, the newest coding schedule in part is as follows：
| Raw information | Respective frequencies |
| 2 | 1kHz |
| 3 | 2kHz |
| 4 | 3kHz |
| 5 | 4kHz |
Then in (n+1) secondary identification, newest coding schedule may be as follows：
| Raw information | Respective frequencies |
| 2 | 3kHz |
| 3 | 2kHz |
| 4 | 6kHz |
| 5 | 5kHz |
Coding rule function is substituted into by regarding the coding generated at random watch key as input parameter, generates the knowledge of this identity
Other newest coding schedule so that can time time more with reference to the newest coding schedule of table as key message audio coding correspondence
Change, and replace at random, though someone replicates user for the ultrasonic signal of identification with personation identity, and
It is otiose, it greatly ensure that the accuracy of identification and prevent pretending to be mechanism.
In another embodiment, sending the mode that terminal is encoded according to coding rule function can be：By key
In each character input coding rule function in information, you can export the corresponding ultrasonic frequency of each character, finally
It can determine that the ultrasonic frequency form of key message.In another embodiment, sending terminal can be according to coding rule letter
Number obtains newest coding schedule, and the corresponding ultrasonic frequency form of key message, identification terminal are determined further according to the newest coding schedule
The decoding of corresponded manner is carried out according to coding rule.
Newest coding schedule refers in this identification, for decoding the coding schedule of key message, in other words by key message
The correspondence of audio-frequency information is encoded into reference to table.To ensure the security of identification, for decoding the coding of key message
Table is different in identifications different each time.
Presetting database, can be identification terminal local data base, or cloud database, can be server count
According to storehouse.The correspondence of user identifier and coding rule is stored with the presetting database, can be by user identifier with compiling
The correspondence of code rule, obtains the corresponding coding rule of the user identifier, to determine final newest coding schedule.
If by the storage of the correspondence mapping table of user identifier and coding rule in the server, it can reduce to identification terminal
The software and hardware requirement of memory, and then the hardware cost of identification terminal is reduced, be conducive to the popularization of identification terminal.
Step S30, according to the key message frequency range in the newest coding schedule decoding effectively audio files, obtains body
Part information.
The key message portion in key message frequency range in the newest coding schedule decoding effectively audio files
Point, the identity information in key message can be obtained.
In decoding, the frequency peak of the key message frequency range in the effectively audio files can be obtained first, according to institute
State newest coding schedule and determine the corresponding character information of the frequency peak, which is identity information.
Peak value therein can be obtained by audiograph or ultrasonic frequency peak value is determined by ultrasonic frequency peak function,
Here identity information need to be only obtained, so key message frequency range part in effective audio files need to be only decoded, according to described newest
Coding schedule determines the corresponding character information of the frequency peak, which is identity information, and frequency peak is relatively easy to obtain
, either send terminal be audio signal by key message transcoding, or identification terminal reception key message is identified
The interference of other frequencies compared with simple realization, can be all excluded, the identity information of acquisition is more accurate.
Further, the step S30 includes：
Step S31, according to the key message frequency range in the newest coding schedule decoding effectively audio files, obtains just
Level identity information；
Step S32, according to the user identifier determine the key message frequency range effectively in audio files whether have into
Row scale coding；
Step S33, if the key message frequency range has carry out scale coding, obtains the corresponding system of the user identifier
Number；
Step S34, decodes the primary identity information according to the system number, obtains identity information.

Further, in personal identification method second embodiment of the present invention, according to effective source of sound described in step S10
The step for file acquisition user identifier and coding watch key, includes：
Step S11, obtains user identifier frequency range and key frequency range in the effectively audio files, decoding the user's mark
Frequency range, to obtain user identifier；
User identifier frequency range and key frequency range in effective audio files be probably positioned at specific location frequency range either
How frequency range with frequency-specific feature, specifically determine that user identifier frequency range and key frequency range can be by the bodies in identification terminal
Part recognition rule determines.In one embodiment, user identifier is in the head position (i.e. forefront) of effective audio files, key
Spoon frequency range follows user identifier, user identifier and the character that coding watch key is regular length closely, and identification terminal is directly according to pre-
If user identifier and the coding watch key length and position in sound wave, determine to represent user identifier with encoding the frequency of watch key
Section.In another embodiment, user identifier and the frequency range of coding watch key have fixed frequecy characteristic, for example, user
Frequency range of the frequency range for the regular length of certain specific frequency beginning is identified, which is 1kHz, i.e., user identifier frequency range is to be somebody's turn to do
The frequency range of regular length after the frequency of 1kHz.
Obtain in effective audio files after user identifier frequency range and key frequency range, it is necessary to be decoded to it.Decoding is used
The decoding rule of family mark frequency range should be the general decoding rule of all users, because identification terminal is obtaining user identifier frequency
Section and before parsing the user that the frequency range refers specifically to generation, in this case it is not apparent that the effectively audio files are sent by which user, such as
The decoding rule of fruit user identifier frequency range is non-universal, but different user has different decoding rules, then identification terminal never may be used
Can decoding.Decoding rule can be fixed decoding table, and identification terminal can decode user identifier frequency range according to the decoding table.

The table of character ([0-9, a-v]), each character map to frequency meter.Such as 0=2kHz, 1=3kHz, 2=4kHz etc..Decoding table
It is two aspects of a things with coding schedule, is encoded user identifier according to coding schedule, it is possible to decoded according to the coding schedule.
When by identification information needed coding transmission, because ultrasonic wave transmission information content is limited, it will first can transmit
Identity information carry out scale coding to reduce data volume, i.e., identification information needed is carried out to the coding of high system, such as
By binary number, either decimal number transcoding is hexadecimal number or duotricemary notation number.Contained much information according to what need to be transmitted
It is small, it can be set by identification terminal or program developer and be transcoded into the transcoding mode of transmission code by information need to be transmitted, such as need to pass
Defeated identity information data amount is larger, which can be converted into duotricemary notation, and the information content of the equal scale of construction corresponds to
Transmission code reduce, the total amount of data finally transmitted can increase；If transmission numeral, first can be transcoded into hexadecimal number by numeral,
If transmission letter, a letter can change into two hexadecimal characters.
Further by taking transmitting cell-phone number as an example：Because cell-phone number is all with 1 beginning, then 1 can not pass, cell-phone number one
As with 13,15,18 beginning, so being first mapped as 1,2,33,5,8, then do hexadecimal transcoding again, pass through before transmission turn
Code, cell-phone number can be reduced to 9 or 8 by finally optimizing.

There is different regular coding tables with user.If all users have general regular coding table, identification terminal is obtaining the use
After family identifies frequency range and key frequency range, you can while decode and obtain user identifier and decoding key, corresponded to compared to different user
Different regular coding tables, identification terminal is using general regular coding table without in addition storing user and pair of regular coding table
It should be related to, need not more perform search operation, identification terminal memory source and operation resource can be saved；If different user has different
Regular coding table, then for identification terminal after user identifier is determined, inquiry the user identifies corresponding regular coding table, further according to looking into
The regular coding table arrived decodes the key frequency range, because the broadcast characteristic of ultrasonic wave, information is transmitted using ultrasonic wave in user
When carrying out identification, there may be other people that the ultrasonic wave of the user's broadcast is recorded, to pretend to be the user, if identity is known
Each user has general regular coding table when other, then other people can obtain general regular coding table, decodes the effective source of sound text recorded
Part can obtain user identifier and coding watch key, only need to obtain coding rule again, it is possible to obtain newest coding schedule, Jin Ershi
Now pretend to be purpose, and use the different regular coding table of each user, then other people obtain effective audio files, obtain user identifier
Afterwards, also need to obtain the regular coding table that the user identifies uniqueness, also need to obtain the unique coding rule of the user's mark, increase
Other people falsely use the difficulty and cost of identity, thus can improve security.
The regular coding table particular content is consistent with above concerning decoding user identifier frequency range part, does not repeat.
Coding watch key refers to a string of characters for obtaining newest coding schedule.
The present embodiment is by decoding user identifier frequency range and key frequency range in the effectively audio files, to obtain user
Mark and coding watch key so that next code is regular and the acquisition of newest coding schedule operation is smoothed out；Meanwhile pass through elder generation
User identifier is obtained, is identified further according to the user and determines corresponding regular coding table, decoding key frequency range obtains coding watch key,
The corresponding different regular coding tables of different user mark, can further enhance the security and accuracy of identification.
