[0023] 具体实施方式 [0023] DETAILED DESCRIPTION

[0024] 以下结合附图和实施例详细说明本发明技术方案。 [0024] Examples and detailed description of embodiments of the present invention, the following technical solutions in conjunction with the accompanying drawings.

[0025] 本发明实施例提供的基于动态密码的触摸屏手机解锁方法可采用软件技术实现,流程图参见图7: [0025] The embodiment of the present invention may employ software technology provided a method of unlocking a touch screen phone based dynamic password, see the flowchart of FIG. 7:

[0026] 步骤1,判断是否要设置指纹样本,是则在触摸屏上提供指纹输入框,采集指纹输入框获取的指纹数据作为指纹样本,并将指纹样本存储至手机的数据库中,否则进入步骤2进行验证。 [0026] Step 1, it is determined whether to set the fingerprint sample, is then provided on the touch screen fingerprint input box, fingerprint data of the fingerprint input box acquired as fingerprint samples, and Fingerprint samples are stored to the phone's database, otherwise, step 2 authenticating.

[0027] 首次使用此功能时,需采集指纹样本。 When [0027] the first time to use this feature, need to collect fingerprint samples. 这其中包括指纹识别、指纹存储等过程以及系统核对指纹次数和欢迎语等功能设置。 This includes fingerprint recognition, fingerprint storage and other processes as well as the number of fingerprint verification system and welcome language settings and other functions. 用户可以根据个人需求向数据库添加指纹数据。 Users can add fingerprint data to the database according to individual needs. 手机的数据库可采用现有技术实现,后续验证使用数据库保存的已有数据。 Mobile database prior art can be implemented using existing subsequent verification data stored in the database. 可以在手机的中央处理器(CPU )中留出存储指纹数据的空间。 You can make room to store fingerprint data in the phone's central processing unit (CPU) in.

[0028] 步骤2,在触摸屏上提供指纹输入框,采集指纹输入框获取的指纹数据,对比指纹输入框获取的指纹数据和手机的数据库中存储的指纹样本,判断是否匹配,是则进入手机的系统,否则进入步骤3。 [0028] Step 2, provided on the touch screen fingerprint input box, fingerprint sample fingerprint data of the fingerprint input box acquired fingerprint data collation fingerprint input box acquired and phones stored in the database, determines whether the match is then into the phone system, otherwise go to step 3.

[0029] 步骤3,判断验证次数是否达到预设的验证次数上限,是则进入步骤4,否则返回步骤2重新进行下一次验证。 [0029] Step 3, it is determined whether the number of authentication times reaches a predetermined upper limit of verification, the process proceeds to a step 4, otherwise return to step 2 once again verified below.

[0030] 验证次数上限可由用户或手机厂商预先根据情况设置,实施例设置为3。 [0030] Verification limit mobile phone manufacturers in advance by the user or set according to the situation, for example to the third embodiment.

[0031 ] 步骤4,提示用户输入手机的PIN码,判断用户输入手机的PIN码是否正确,是则进入手机的系统,否则禁止进入手机的系统。 [0031] Step 4, the phone prompts the user to enter a PIN code, enter the phone user to determine whether the correct PIN code, then enter the mobile phone system is otherwise prohibited from entering the phone system.

[0032] 步骤2、3、4实现验证过程,当用户输入的指纹与数据库中已存储的指纹数据相匹配时,便可成功登录手机系统;若两者无法匹配,则弹出提示窗口,要求用户重新输入指纹并进行核对,直至用户设置的验证次数上限为止。 [0032] Step 2,3,4 implement the verification process, when the fingerprint data with the fingerprint database stored user input matches, you can successfully log phone system; if they are not matched, the prompt window pops up asking the user So far the number of times the upper limit of verification and re-enter the fingerprint check until the user settings. 如果在规定的验证次数上限内无法成功解锁,则启用紧急通道一PIN码。 If you can not successfully unlocked within the upper limit of the number of verification provisions, emergency access a PIN code is enabled. 用户可输入手机的PIN码进行手机解锁。 The user can enter the phone PIN to unlock the phone.

[0033] 经过对比分析,本发明建议手机所采用最优的触摸屏是电容式触摸屏。 [0033] By comparison analysis, the present invention proposes a mobile phone used by most touch screen is a capacitive touch screen. 电容式触摸屏的构造主要是在玻璃屏幕上镀一层透明的薄膜体层,再在导体层外加上一块保护玻璃,双玻璃设计能彻底保护导体层及感应器。 Capacitive touch screen is constructed mainly on a glass screen coated with a transparent thin film layer, an outer conductor layer and then adding a protective glass, double glass design can completely protect the conductor layer and sensors. 电容式触摸屏在触摸屏四边均镀上狭长的电极,在导电体内形成一个低电压交流电场用户触摸屏幕时,由于人体电场,手指与导体层间会形成一个耦合电容,四边电极发出的电流会流向触点,而电流强弱与手指到电极的距离成正比,位于触摸屏幕后的控制器便会计算电流的比例及强弱,准确算出触摸点的位置。 When the capacitive touch screen in the touch screen four sides are coated with an elongated electrode, forming a low-voltage AC electric field user touches the screen in the conductive body, since between the human field, the fingers and the conductor layer will form a coupling capacitor, current flows to contact the four sides from the electrodes point, and the position of the current strength proportional to the distance to the finger electrodes, the controller of the touch screen will calculate the ratio of the strength of current and accurately calculate the touch point. 电容触摸屏的双玻璃不但能保护导体及感应器,更有效地防止外在环境因素对触摸屏造成影响,就算屏幕沾有污秽尘埃或油溃,电容式触摸屏依然能准确算出触摸位置。 Capacitive touch screen of double glass not only protect the conductors and sensors, to more effectively prevent external environmental factors impact on the touch screen, even if the screen piles of dirty dust or oil collapse, capacitive touch screen is still able to accurately calculate the touch location.

[0034]用户对触摸屏的接触通过触摸传感技术采集,可采用现有技术。 [0034] user contact with the touchscreen by touching a sensor technology to collect, the prior art may be employed. 现有技术中触摸屏手机的屏幕由外到里依次为:触摸屏、触摸检测部件、显示器、触摸屏传感控制器。 The prior art touch screen phone screen from outside to inside as follows: a touch screen, the touch detection means, a display, a touch screen sensor controller. 触摸传感控制器目前提供一些通用的性能选项和形态,如滑块和邻近传感器。 Touch sensor controller currently available options and some common morphological properties, such as the slider, and a proximity sensor. 触摸传感器技术的进步使传感器驱动型接口更易于实现,对终端用户更为直观和简单。 The touch sensor technology advances the sensor-driven interfaces easier to implement and more user intuitive and simple. 大多数触摸传感控制器依据所检测到的电容变化来工作。 Most touch sensor controller based on the detected change in capacitance work. 当某种物体或某个人接近或触摸传感器的导电金属片时,手指与金属片之间的电容发生变化。 When the capacitance between the certain object or a person or a proximity touch sensor conductive metal sheet, the metal sheet is changed with the fingers. 导电物体(如手指)在传感器附近移动将改变电容传感器的电场线并使电容发生变化。 Conductive object (e.g., a finger) moves in the vicinity of the sensor will change the field lines and the capacitance of the capacitive sensor changes. 控制电路可测出电容的变化。 The control circuit may detect changes in capacitance. 触摸传感器接口通常通过测量与传感器垫片相连的电路的阻抗来检测电容变化。 Typically touch sensor interface capacitance change is detected by the impedance measuring circuit connected to the sensor pad. 触摸控制器周期性地测量传感器输入通道的阻抗并用这些值来导出一个内部基准,即校准阻抗。 The touch controller periodically measures the impedance sensor input channels and use those values ​​to derive an internal reference, i.e., the calibration impedance. 控制器以这个阻抗值为基础判定是否发生了触摸事件。 This impedance controller based on the value to determine whether a touch event occurs.

[0035] 步骤I采集指纹样本和步骤2获取指纹数据需要进行指纹识别。 [0035] Step I Step 2 fingerprinted samples and acquiring fingerprint data need fingerprinting. 具体指纹识别目前有两种现有技术:A、读取指纹图像,对初步读取到的人体指纹图像进行清晰处理;建立指纹的数字特征数据;利用模糊比较法,对输入指纹和已存指纹进行对比。 There are two specific fingerprint prior art: A, reads the fingerprint image, the preliminary read fingerprint image clearly human processing; establishing digital fingerprint characteristic data; fuzzy comparison, the input fingerprint and the stored fingerprints comparing. B、取像和取像设备,光学设备(历史久远),利用光的全反射原理;优点:体积小(3*1*1英寸);纤维光、微型三棱镜矩阵,硅晶体传感器(最近),例如:电容传感器、温度感应传感器、超声波扫描(指纹取像技术中非常好的一类,建议使用)。 B, imaging, and imaging device, an optical device (a long history), using the principle of total reflection of light; advantages: small size (3 * 1 * 1 inch); a fiber optic, micro-prism array, a silicon crystal sensor (last), For example: a capacitive sensor, a temperature sensor sensing, ultrasonic scanning (fingerprint image capturing art a class of very good recommended). 通过对两种方式比较,前一种价格低、体积小、识别率闻。 By comparing the two methods, the former low-price, small size, smell recognition rate.

[0036] 为改进指纹识别效果,可以进行图像增强:当手指不干净或者有伤疤、干燥、湿润时,不能获得清晰的图像。 [0036] In order to improve the effect fingerprint recognition, image enhancement may be performed: when a finger is not clean or scarred, drying, wetting time, a clear image can not be obtained. 为了克服这种现象,可以设计一个适合、匹配的滤镜和恰当的阀值。 In order to overcome this phenomenon, we can design a suitable matching filter and appropriate threshold. 可参考第三代生物射频传感器:第三代生物射频指纹识别技术,射频传感器技术是通过传感器本身发射出微量射频信号,穿透手指的表皮层去控测里层的纹路,来获得最佳的指纹图像。 Reference may be third generation of RF sensors: third generation of radio frequency fingerprint identification technology, radio frequency sensor technology by the sensor itself emits a radio frequency signal trace, the fingers penetrate the epidermis to the control lines in the sensing layer to obtain the best fingerprint images. 因此对干手指,汉手指等困难手指通过可高达99%,防伪指纹能力强,指纹敏感器的识别原理只对人的真皮皮肤有反应,从根本上杜绝了人造指纹的问题,宽温区:适合特别寒冷或特别酷热的地区。 So dry fingers, Han and other difficulties finger by finger can be up to 99%, and strong fingerprint security, fingerprint sensor recognition principle only respond to people's genuine leather skin, eliminate the problem of man-made fingerprint fundamentally, Wide Temperature Range: suitable for particularly cold or particularly hot areas. 因为射频传感器产生高质量的图像,因此射频技术是最可靠,最有力的解决方案。 Because the RF sensor to produce high quality images, RF technology is the most reliable and robust solutions. 除此之外,高质量图像还允许减小传感器,无需牺牲认证的可靠性,从而降低成本并使得射频传感器思想的应用到可移动和大小不受拘束的任何领域中。 In addition, high-quality image sensors also allows to reduce, without sacrificing the reliability of authentication, thereby reducing costs and makes the application of the RF sensor thought to any field, and movable in size unconstrained.

[0037] 本发明进一步提出,可以采集一个以上手指的指纹样本并存储至手机的数据库中;当进入步骤2进行验证时,在触摸屏上提供相应数目的钥匙图标,当用户点击某一钥匙图标时,在触摸屏上提供指纹输入框,对比指纹输入框获取的指纹数据和手机的数据库中存储的相应指纹样本。 [0037] The present invention further proposes, can fingerprint sample more than one finger and stored in the phone's database; when the routine proceeds to step 2 for authentication, providing a corresponding number of key icon on the touch screen, when the user clicks on a key icon provided fingerprint input box on the touch screen, the corresponding fingerprint collation fingerprint sample fingerprint data input box acquired and stored in a database of the phone. [0038] 为便于实施参考,提供实施例的具体实现流程说明如下: Specific implementation process [0038] To facilitate reference, the embodiments are provided as follows:

[0039] (I)当用户首次使用此功能时,需进行指纹数据采集,经过信息处理后,将该数据存至数据库中。 [0039] (I) When the user first to use this feature, the need for acquisition of fingerprint data, after processing the information, the data is stored into the database. 此步骤是对指纹数据的采集、图像与处理的综合应用,包括以下子步骤。 This step is the comprehensive application of the fingerprint data acquisition, image processing, comprising the sub-steps.

[0040] (1.1)如图8所示,实施例所用手机的屏幕由外到里依次为:触摸屏101、触摸检测部件102、显示器103、触摸屏传感控制器104和指纹采集器105。 [0040] (1.1) shown in Figure 8, the embodiment of the phone screen from outside to inside as follows: a touch screen 101, the touch detection section 102, a display 103, a touch screen controller 104 and the fingerprint sensor 105. 指纹采集器可参考现有技术实现,例如晶体传感器等。 Fingerprint may be implemented with reference to the prior art, such as a crystal sensor. 所得指纹存储至手机的数据库106中。 The resulting fingerprint stored in the phone's database 106.

[0041] 在用户的手指触摸安装在显示器前端的触摸屏之后,系统根据手指在指定位置的指纹录入进行数据分析。 After [0041] the user's finger touches a display mounted on the front end of a touch screen, the data analysis system in accordance with the specified location fingerprint input finger. 触摸检测部件位于显示屏幕前,主要作用是检测用户触摸位置,而触摸屏传感控制器的主要作用是从触摸检测装置上接受触摸信息,并将其转换成出点坐标,再传送给手机的CPU ;同时指纹采集器采集指纹的图像,所得采集图像输入CPU。 Detecting means located in the foreground touch screen, the main role is to detect user touch location, touch screen and the main role is to accept the touch sensor controller information from the touch detection device and converted into a coordinates, and transmits it to the phone's CPU ; while the fingerprint reader fingerprint image, the resulting image input capture CPU. 这时坐标数值将会与指纹采集器的坐标数值(和预设的指纹输入框位置一致)进行比较,若输入的坐标在指纹处理器的坐标之内,则CPU开始进行指纹图像的处理。 At this time will coordinate values ​​(input box and the preset fingerprint coincides with the position) and the coordinate value of the fingerprint is compared, if the input coordinates in the coordinate processor of the fingerprint, the CPU starts processing of the fingerprint image.

[0042] (1.2)指纹图像处理主要包括图像采集、图像预处理、细节点提取及指纹匹配。 [0042] (1.2) fingerprint image processing includes image capture, image preprocessing, minutiae extraction and fingerprint matching. 其中在(1.1)通过指纹采集器已完成对图像采集,指纹采集器采集的图像输入CPU,接下来需要进行图像预处理。 Wherein in (1.1) by the fingerprint image capture has finished, an acquired fingerprint image input the CPU, the next image preprocessing is required. 预处理的目的是去除图像中的噪声,把它变成一幅清晰的点线图,以便提取正确的指纹特征,从而达到正确匹配。 The purpose of preprocessing is to remove noise in the image, it becomes a dotted line in FIG clear, so that the correct fingerprint feature extraction, so as to achieve the correct match. 预处理过程主要包括指纹规格化、平滑滤波处理、方向增强处理、二值化、细化等,可采用现有技术,本发明不予赘述。 Pretreatment process includes fingerprint normalization, smoothing filter processing direction enhancement processing, binarization, thinning, etc., may be employed prior art, the present invention is not repeated here.

[0043] (1.3)在步骤(1.2)的基础上提取指纹特征信息,得到指纹特征模板,即可作为指纹样本存储至指纹数据库中的有效数据。 [0043] extracts the base (1.3) in step (1.2) of the fingerprint feature information, a feature template fingerprint, the fingerprint can be used as valid data samples stored in the fingerprint database.

[0044] 以上指纹图像的处理过程可采用软件编程技术由cpu执行实现,也可以将图像预处理过程模块化设计为采用图像转换器实现,生成输入指纹特征模板可模块化设计为采用指纹模板处理器实现。 [0044] The process of the above fingerprint image is performed by software programming techniques may be employed to achieve cpu, image preprocessing may be modular design implemented using the image converter generates the input fingerprint feature template may be designed as a modular process using fingerprint template implemented. 指纹采集器输出图像到图像转换器,图像转换器输出到指纹模板处理器,然后存储到数据库。 Fingerprint image to the output image converter, image converter outputs to a fingerprint template of the processor and stored in the database.

[0045] 为了提高效率,具体实施时,用户输入指纹时可以先通过触摸屏进行指纹触点的定位及判断;当采集指纹输入框获取的指纹数据时,先根据触摸屏传感控制器采集后输入手机的中央处理部件的坐标信息,判断用户输入的坐标是否在指纹输入框内,是则对采集图像进行图像预处理并提取指纹特征信息,否则提示重新输入。 [0045] To improve efficiency, when the specific embodiment, the fingerprint may be first positioned and contacts the touch screen is determined by a user to input a fingerprint; fingerprint when the fingerprint data input box acquired, the mobile phone according to the first input controller collects sensing touchscreen the central processing unit coordinate information, it is determined whether the coordinates of the user input fingerprint input box, for the acquired image is an image preprocessing and extract minutiae information, or prompt to re-enter. 可以通过触摸检测部件和触摸屏传感控制器的坐标数值与指纹处理器的坐标数值进行比较,若所输入的内容的坐标在指纹处理器的坐标之内,则CPU开始进行指纹图像的处理。 Coordinate values ​​may be coordinate values ​​by comparing the fingerprint of the processor and the touch screen means detects a touch sensor controller, if the coordinates of the input content within a coordinate processor of the fingerprint, the CPU starts processing of the fingerprint image. 所输入的指纹在规定范围内时,采用指纹处理器处理得到指纹特征模板,并将其存入数据库中。 When the input fingerprint within a predetermined range, wherein the fingerprint template fingerprint obtained processor, and stores it in the database.

[0046] 步骤2中,先判断用户输入的坐标是否在指纹输入框内,是则对比指纹输入框获取的指纹数据和手机的数据库中存储的指纹样本,否则提示重新输入。 In [0046] Step 2, first determine whether the coordinates of the user input box in the input fingerprint, the collation fingerprint is the fingerprint sample input box acquired fingerprint data stored in the database and the mobile phone, or be prompted to re-enter.

[0047] (2)用户每次使用手机,验证使用过程如下: [0047] (2) each phone user, using the authentication process is as follows:

[0048] 用户每次使用手机,点亮屏幕时,会出现一扇已有一把锁的中国式大门(大门旁边会有一把或并列摆有几把钥匙(根据数据库里的指纹个数决定。即指纹库有一个指纹,桌面上有一把钥匙),如图1。 [0048] Every time a user to use the phone, the screen is lit, there will be a Chinese-style has a lock of the door (next to the door there will be a tie or put a few keys (determined according to the number of fingerprint database of words fingerprint library has a fingerprint, there is a key on the desktop), shown in Figure 1.

[0049] 当用户点击钥匙图标时,屏幕会显示如图2所示的空白区域作为指纹输入区,弹出“开启指令”提示用户输入指纹。 [0049] When a user clicks an icon key, the screen will display a blank area shown in FIG. 2 as a fingerprint input area, the pop-up "on command" to prompt the user to input a fingerprint. 对输入指纹的采集、图像与处理与(I)实现方式一致,具体匹配可采用现有技术。 Acquisition of the input fingerprint image and processing (I) to achieve a consistent manner, in particular matching the prior art may be employed. [0050] 当用户的指纹信息匹配成功时,画面中门上的锁会自动打开,并且出现欢迎语(用户可个性化设置,例如“Welcome ! ”)开门后即可看到手机桌面信息,如图3。 [0050] When the user's fingerprint information matches, the lock on the screen door will open automatically, and the Welcome language (the user can personalize settings such as "Welcome!") You can see the phone desktop information to open the door, such as image 3.

[0051] 若用户的指纹匹配不成功,则会弹出提示信息“请重新输入指令”要求用户在指纹区重新输入。 [0051] If the user's fingerprint matching is unsuccessful, it will pop-up message "Please re-enter the command" requires the user to re-enter in the fingerprint region. 同时,门锁会增加一把锁(门锁增加的个数由机主设定的验证次数有关,例如,机主设定验证次数为三,则门锁最大值有3把),如图4出现了两把锁。 Meanwhile, a door lock increases (increasing the number of times authentication lock set by the owner related, e.g., to verify the owner is set to three times, the lock 3 has a maximum value), as shown in FIG 4 there have been two locks.

[0052] 若三次验证权限已用完,屏幕会显示“抱歉,开启不成功,您无法进入! ”,如图5,出现了三把锁。 [0052] If the three verification authority has run out, the screen will display "Sorry, turned unsuccessful, you can not enter!", Shown in Figure 5, there have been three locks.

[0053] 为了确保因识别不清晰等因素干扰到本机机主无法正常使用手机,在如图5所示情况发生时,桌面的右下角会有“紧急通道”字样。 [0053] In order to ensure identification is not clear due to factors such as interference to the machine owner can not use the phone normally, when the occurrence of the case shown in FIG. 5, lower right corner of the desktop will be the "emergency channel" word. 当用户点击时,屏幕会弹出“请输入本机PIN码”的提示,如图6。 When the user clicks, the screen will pop up prompt "Please enter this PIN code machine", as 6. 这时用户只要输入正确的PIN码即可进入到自己的手机系统中。 Then users simply enter the correct PIN code to enter into their phone systems.

[0054] 若用户最终无法解锁手机或手机丢失时,用户可到该手机品牌的官网上进行挂失。 [0054] If the end-user can not unlock the phone or the phone is lost, users can phone to the brand's official website report the loss. 在输入自己的身份证等有效证件后,便可通过云服务读取下载自己的重要信息。 After entering their valid identity cards and other documents, can be downloaded to read their important information in the cloud. 用户在使用时需将自己的信息上传到云服务器的前提下,才可下载读取信息。 When the user needs to use their information is uploaded to the cloud server premise, read the information before downloading. 这样既可以保护行货手机的版权,与水货手机服务相区别,又可以为用户提供方便安全的服务。 This is to protect the copyright of mainstream mobile phones, distinguished parallel phone service, but also provide a convenient and secure service to users.

[0055] 验证过程中的获取指纹数据具体实现与(I)中采集指纹样本的具体实现一致。 [0055] consistent with the fingerprint data acquired from the verification process embodied with (I) the fingerprint of the sample implementation.
