Brief description
Fig. 1 is the schematic flow sheet of the online verification method that the present invention provides；
Fig. 2 is the structural representation of the online verification system that the present invention provides.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.As long as additionally, involved technical characteristic in each embodiment of invention described below
The conflict of not constituting each other just can be mutually combined.
The online verification method that the present invention provides, as shown in figure 1, comprise the following steps：
(1) show random string；Described random string, preferably includes to formulate the characteristic point of number.Described characteristic point
The special pronunciation easily identifying for lip, such as w, zh, a etc..Preferably, in order to strengthen Consumer's Experience, really it is used for coupling
Character string is the front half section of all character strings of display, for example, show：" facing sea, during the warmth of spring, all the flowers bloom ", is actually used in coupling
Character string is " facing sea ".Because the Dual Matching that the present invention adopts is relatively time-consuming, carry out the second half section in user and " face flower
Open " phonetic entry while, actual complete to mate work, thus shortening the time of the actual wait of user, raising experience.
(2) obtain user and pass through the volume audio-frequency information of random string of display and image letter in phonetic entry step (1)
Breath；Described image information is preferably lip motion information, also can increase facial information as auxiliary checking.
The equipment needed for audio-frequency information and image information that obtains is pick up and photographic head, and most terminal sets at present
Standby, such as PC, mobile phone, ATM etc., all standard configuration pick up and photographic head, the therefore present invention will not additionally increase
Plus checking equipment.
(3) by the audio-frequency information obtaining in the random string obtaining in step (1), step (2) and image information, carry out
Coupling, calculates matching degree；
Described matching degree is the voice match degree and audio-frequency information and lip that audio-frequency information and random character String matching obtain
The lip matching degree that information matches obtain is long-pending.Actually due to being three's coupling it is thus possible to produce three direct matching values：
I.e. random string and audio-frequency information matching value, audio-frequency information and lip motion information matching value and random string and lip letter
Breath matching value.But realize for difficulty with regard to technology, and speech recognition technology relative maturity, success rate is higher, therefore random character
String is higher with audio-frequency information matching value reliability, can preferably avoid judging by accident.Secondly audio-frequency information is mated with lip motion information, by
Pronunciation in certain language is actually limited, and the amount of calculation that therefore audio-frequency information is mated with lip motion information is less, fault-tolerant
Rate is done, and can improve success rate and shorten the proving time.Therefore, the preferably described matching degree of the present invention is audio-frequency information and random words
It is long-pending that the voice match degree that symbol String matching obtains mates the lip matching degree obtaining with audio-frequency information and lip motion information.
And specifically, it is preferable to according to following two methods, calculate matching degree.

Obtain voice match degree；The character string of the character string obtaining in step (3-1-1) and acquisition in step (3-1-2) is carried out pronunciation
Coupling, obtains lip matching degree；
(3-1-4) using the voice match degree obtaining in step (3-1-3) and lip matching degree long-pending as matching degree.
Method two,
(3-2-1) characteristic point position according to random string, intercept the audio-frequency information characteristic segments obtaining in step (2) and
The characteristic segments of lip motion information；
(3-2-2) sending out the audio-frequency information characteristic segments obtaining in step (3-2-1) and corresponding random string characteristic point
Sound carries out voice match, obtains voice match degree；
(3-2-3) the audio-frequency information characteristic segments obtaining in step (3-2-1) are mated with lip motion information characteristic segments, obtained
Obtain lip matching degree；
(3-2-4) using the voice match degree obtaining in step (3-2-3) and lip matching degree long-pending as matching degree.
(4), when the matching degree obtaining in step (3) exceedes predetermined threshold value, by checking, otherwise reject checking.
The online verification system that the present invention provides, as shown in Fig. 2 include：
