Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.

Mobile terminal involved by the embodiment of the present invention, has unlocked by fingerprint module, can include but is not limited to intelligent hand The mobile communication equipments such as machine, panel computer, can also include the mobile terminal both having had touch-screen and having had physical button, this Bright embodiment does not limit.

With specifically embodiment, technical scheme is described in detail below.These are specifically implemented below Example can be combined with each other, and may repeat no more in some embodiments for same or analogous concept or process.

Fig. 1 is the schematic flow sheet of unlocking method one embodiment of mobile terminal of the present invention.As shown in figure 1, the present embodiment Method, including:

Step 101, the fingerprint of acquisition user, determine the number with the fingerprint feature point of pre-stored fingerprint Feature Points Matching in fingerprint Amount;

Step 102, judge that whether the quantity of fingerprint feature point be less than default first amount threshold, if less than default the One amount threshold, then determine whether whether the quantity of fingerprint feature point is more than default second amount threshold, if more than default The second amount threshold, then obtain other human body physical signs in addition to fingerprint for the user characteristic point;

Wherein, the second amount threshold is more than 1/2nd of the first amount threshold;

Specifically, current unlocked by fingerprint algorithm principle is as follows:

1) the unblock fingerprint that typing is desirable in the terminal in advance.These fingerprints are recognized by the system and extract spy After levying a little, independent comparison template is preserved into specific code.

2) staff presses the fingerprint identification module of mobile terminal, and this fingerprint identification module extracts the fingerprint of staff, and will refer to Line picture is converted to characteristic point.

3) characteristic point that these extract is compared one by one with the fingerprint comparison template of typing, if extracted Characteristic point in be higher than the characteristic point that can unlock setting with the quantity of the fingerprint feature point of minutiae matches prestoring Amount threshold then it is assumed that fingerprint matching is it is allowed to carry out unlocked by fingerprint, whereas if in the characteristic point extracting with the finger that prestores The quantity of the fingerprint feature point of line Feature Points Matching be less than set the characteristic point amount threshold that can unlock then it is assumed that fingerprint not Coupling, does not allow to carry out unlocked by fingerprint.

Generally, different with safe class according to algorithm, features described above point amount threshold can be configured between 5-15, threshold Value is too low, then fingerprint false recognition rate can increase, and threshold value is too high, then the refusal discrimination of fingerprint can reduce.

If the fingerprint texture of user is shallower, or fingerprint occurs in that Local Damaged in use, be stained with greasy dirt water mark or Situations such as appearance seasonality is casted off a skin, the discrimination of fingerprint will substantially reduce, the fingerprint of the coupling of the user fingerprints now obtaining The quantity of characteristic point can reduce, and becomes fewer than the characteristic point amount threshold of the unlocking requirements of setting.Even in these cases The owner of mobile terminal also cannot realize unlocked by fingerprint, therefore can cause poor Consumer's Experience.

In order to overcome the problems referred to above, in the embodiment of the present invention, it is less than default the in the quantity of the fingerprint feature point of coupling One amount threshold, and during more than default second amount threshold, obtain the feature of other human body physical signs in addition to fingerprint for the user Point, can pass through the identification of other human body physical sign features of human body, to make up the few problem of the fingerprint feature point quantity of coupling.

It should be noted that in order to avoid the security feature reducing unblock, preventing mobile terminal from being entered by the third party after losing Row is illegal to be unlocked.Meanwhile, the extraction identification of the characteristic point of other human body physical sign features, is intended only as unlocked by fingerprint mode more Mend, after unlocked by fingerprint mode must reach certain condition, Compensation measures could be started, for the relatively low solution of unlocked by fingerprint matching degree Lock action, then should treat as the action of None- identified effectively, rather than simply by other human body physical sign features Characteristic point making up.The quantity of the fingerprint feature point mating have to be larger than default second amount threshold, i.e. the second quantity Threshold value/the first amount threshold is more than 0.5, wherein ,/be divided by for counting.

In daily life, a lot of users wear carry-on sensor device, such as glasses, bracelet, pin ring, bluetooth earphone etc. Equipment, these equipment, often through wireless modes such as bluetooths, are interconnected with mobile terminal.So, these equipment can be used as human body The collecting device of feature, by specific human body physical sign collection apparatus out, and is wirelessly transmitted to mobile whole by bluetooth etc. End, and make up characteristic point as fingerprint feature point, thus reaching the purpose improving fingerprint recognition rate.
