具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
本申请实施例所描述的电子设备可以包括智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、掌上电脑、笔记本电脑、移动互联网设备(mobile internet devices,MID)或穿戴式设备等,上述电子设备仅是举例,而非穷举,包含但不限于上述电子设备。
请参阅图1,为本申请实施例提供的一种指纹识别方法的实施例流程示意图。本实施例中所描述的指纹识别方法,包括以下步骤:
101、在进入解锁界面后,获取按压指纹识别模组的按压次数。
其中,当电子设备成功进行解锁操作后,即可进入解锁界面,解锁操作可以是输入身份验证信息,并根据该身份验证信息对电子设备进行解锁操作,以 进入电子设备的解锁界面,上述身份验证信息可包括但不仅限于:指纹信息、虹膜信息、字符串、振动参数、轨迹图案、语音信息等验证信息,也可以为上述中的至少两种的组合形式(例如,虹膜信息与指纹信息组合)。
可选地,在进入解锁界面后,只要电子设备没有进入锁屏状态,就可以正常的使用电子设备中的应用。现有技术中,电子设备的指纹识别模组可设置在电子设备的主菜单键(home键)下方,因此,在用户使用电子设备的应用的过程中,常常会按压home键,在按压home键时,即可按压到指纹识别模组。本申请实施例中电子设备可以在用户按压home键后,获取到按压指纹识别模组的按压次数。
102、在所述按压次数达到第一预设阈值时,采集最近一次按压所述指纹识别模组的接触物的第一图像。
其中,上述第一预设阈值可由用户自行设置或者系统默认。当电子设备获取到的按压次数等于第一预设阈值时,电子设备可采集最近一次按压指纹识别模组的接触物的第一图像。例如,第一预设阈值为按压指纹识别模组5次,即可理解为电子设备可采集第五次按压指纹识别模组的接触物的第一图像。当已经获取到4次按压次数后,电子设备即可等待获取第五次按压指纹识别模组的接触物的第一图像。
可选地,在获取到的按压次数未达到第一预设阈值时,若检测到电子设备有成功地进行指纹识别操作时,电子设备会清零当前已经获取的按压次数,并重新获取按压次数。例如,用户在使用电子设备时,可能在使用过程中有进行指纹支付(如支付宝的指纹支付)、指纹验证(如指纹验证后才可进入支付宝应用)等操作,如此可确认当前是用户本人在使用电子设备,因此,可以清零当前已经获取到的按压次数(即将当前按压次数清零,例如,当前次数为3次,清零后按压次数为0次),重新获取按压指纹识别模组的按压次数。
103、将所述第一图像与预设指纹图像进行匹配。
其中,上述预设指纹图像可由用户在实施步骤101之前预先录入。
可选地,上述步骤103,将所述第一图像与预设指纹图像进行匹配,可包括如下步骤:
1031)、在当前应用为预设应用时,获取所述预设应用对应的匹配阈值;
1032)、判断所述第一图像与所述预设指纹图像之间的匹配值是否大于所述匹配阈值,在所述第一图像与所述预设指纹图像之间的匹配值大于所述匹配阈值时,确认所述第一图像与所述预设指纹图像匹配成功。
可选地,预设应用可包括但不仅限于:支付宝应用、微信应用、短信应用等等,本申请实施例中,不同的预设应用可对应不同的匹配阈值,例如,A应用对应第一匹配阈值,B应用对应第二匹配阈值。可按照预设应用与阈值之间的对应关系确定预设应用对应的匹配阈值。
可选地,用户通过设定预设应用可以提高使用预设应用的安全性。若当前电子设备正在运行某个预设应用,这时进行指纹识别操作可先获取与该预设应用对应的匹配阈值。例如,电子设备默认的设定是当第一图像和预设指纹图像的匹配值在百分之八十以上,即可确认为匹配成功。当用户把支付宝应用、微信应用、短信应用等应用设定为预设应用时,这些预设应用对应的匹配阈值可设置为高于百分之八十。例如,当前的预设应用对应的匹配阈值为百分之九十五,当电子设备正在运行该预设应用时,这时候进行指纹匹配工作,需要第一图像和预设指纹图像之间的匹配值在百分之九十五以上,才可由电子设备确认为匹配成功,如此,可提高使用该预设应用的安全性。
104、在所述第一图像与所述预设指纹图像匹配失败时,提示用户输入指纹以进行指纹识别操作。
其中,若第一图像与预设指纹图像匹配失败,电子设备可提示用户输入指纹以进行指纹识别操作,只有在成功进行指纹识别操作后,用户才能再次正常的使用电子设备,此时,电子设备再次进入解锁界面,否则,电子设备可进入锁屏状态。
可以看出,通过本申请实施例,在进入解锁界面后,获取按压指纹识别模组的按压次数,在该按压次数达到第一预设阈值时,采集最近一次按压指纹识别模组的接触物的第一图像,将该第一图像与预设指纹图像进行匹配,在该第一图像与该预设指纹图像匹配失败时,提示用户输入指纹以进行指纹识别操作。从而,可使电子设备在解锁状态下,可采集指纹,并在该指纹验证失败的情况下,再次提示用户输入指纹,以实现指纹识别操作,如此,可提高使用电子设备的安全性。
与上述一致地,请参阅图2,为本申请实施例提供的一种指纹识别方法的实施例流程示意图。本实施例中所描述的指纹识别方法,包括以下步骤:
201、在进入解锁界面后,获取按压指纹识别模组的按压次数。
其中,上述步骤201可参考图1所描述的指纹识别方法的步骤101
202、在所述按压次数未达到所述第一预设阈值且处于所述解锁界面的时 长大于第二预设阈值时,执行等待采集下一次按压所述指纹识别模组的接触物的第二图像。
其中,上述第二预设阈值可由用户自行设置或者系统默认。若当前检测到的按压次数未达到第一预设阈值,但是电子设备处于解锁界面的时长大于第二预设阈值,电子设备可以执行等待在下一次按压指纹识别模组时,采集接触指纹识别模组的接触物的第二图像。因为在具体实现中,可能会出现用户在使用电子设备时,不会频繁按压home键的情况,即不会频繁按压指纹识别模组,所以可以设定一个时间阈值,在超过这个时间阈值后,电子设备会自动采集在这个时间后的第一次按压指纹识别模组的接触物的第二图像。例如,第二预设阈值为30分钟,第一预设阈值为按压次数5次,当电子设备处于解锁界面的时间超过了30分钟,在下一次按压指纹识别模组的时候,即使这时候按压指纹识别模组的按压次数没有达到5次,电子设备也可执行采集按压指纹识别模组的接触物的第二图像。
可选的,在实施上述步骤202的过程中,若检测到当前正在运行视频或者游戏,延长所述第二预设阈值。
例如,若当前用户正在使用电子设备观看视频,或者玩游戏,这时候用户也不会频繁按压指纹识别模组,并且用户可能在一两个小时内,都不会按压指纹识别模组,此时电子设备若检测到当前正在运行视频、游戏等应用时,可以延长第二预设阈值,例如将30分钟延长到一个小时,以免电子设备一直处于等待采集第二图像的状态。
203、采集所述第二图像。
204、将所述第二图像与预设指纹图像进行匹配。
205、在所述第二图像与所述预设指纹图像匹配失败时,提示用户输入指纹以进行指纹识别操作。
其中,上述步骤203-步骤205可参考图1所描述的指纹识别方法的对应步骤,在此不再赘述。
可以看出,通过本申请实施例,在进入解锁界面后,获取按压指纹识别模组的按压次数,在该按压次数未达到所述第一预设阈值时且处于解锁界面的时长大于第二预设阈值时,执行等待采集下一次按压指纹识别模组的接触物的第二图像,采集第二图像,将该第二图像与预设指纹图像进行匹配,在该第二图像与该预设指纹图像匹配失败时,提示用户输入指纹以进行指纹识别操作。从而,可使电子设备在解锁状态下,在一定时间内自行进行指纹识别操作,提高 使用电子设备的安全性。
与上述一致地,请参阅图3,为本申请实施例提供的一种指纹识别方法的实施例流程示意图。本实施例中所描述的指纹识别方法,包括以下步骤:
301、在进入解锁界面后,获取按压指纹识别模组的按压次数。
302、在所述按压次数达到第一预设阈值时,采集最近一次按压所述指纹识别模组的接触物的第一图像。
302、将所述第一图像与预设指纹图像进行匹配。
304、在所述第一图像与所述预设指纹图像匹配失败时,提示用户输入指纹以进行指纹识别操作。
其中,上述步骤301-步骤304可参考图1所描述的指纹识别方法的步骤101-步骤104。
305、获取用户输入的第三图像。
其中,在第一图像和预设指纹图像匹配失败时,电子设备可出现指纹识别的提示界面,提示用户输入指纹以进行指纹识别操作,只有在指纹识别操作成功后用户才可继续使用电子设备。这时用户只能输入指纹进行指纹识别操作,不能切换到密码输入界面。若不是用户本人,或者原本在电子设备有录入指纹的用户,就不能再继续使用电子设备,若指纹识别操作失败,电子设备会进入锁屏状态。
306、在所述第三图像与所述预设指纹图像匹配成功时,清零所述按压次数,重新获取所述按压次数。
其中,若第三图像和预设指纹图像匹配成功,即成功进行了指纹识别操作,电子设备再次进入解锁界面,这时,可以清零之前获取到的按压指纹识别模组的按压次数,再重新获取按压次数。
可选地,在第三图像和预设指纹图像匹配失败时,可控制电子设备进入锁屏状态。
可以看出,通过本申请实施例,在进入解锁界面后,获取按压指纹识别模组的按压次数,在该按压次数达到第一预设阈值时,采集最近一次按压所述指纹识别模组的接触物的第一图像,将该第一图像与指纹图像进行匹配,在该第一图像与该预设指纹图像匹配失败时,提示用户输入指纹以进行指纹识别操作,获取用户重新输入的第三图像,在该第三图像与该预设指纹图像匹配成功时,清零该按压次数,重新获取该按压次数。从而,可使电子设备在解锁状态 下,自行进行指纹识别操作,以防电子设备密码泄露后被他人使用,提高了使用电子设备的安全性。
