技术领域Technical field

本申请实施例涉及生物识别技术领域，特别涉及一种生物信息识别方法、装置、***及计算机可读存储介质。The embodiments of the present application relate to the field of biometrics technology, and in particular, to a biometrics identification method, device, system, and computer-readable storage medium.

背景技术Background technique

掌静脉，顾名思义，就是手掌内静脉。掌静脉识别是静脉识别的一种，属于生物识别，掌静脉识别***就是首先通过静脉识别仪取得个人掌静脉分布图，从掌静脉分布图依据专用比对算法提取特征值，通过近红外线电荷藕合器件(Charge Coupled Device，CCD)摄像头获取手指、手掌、手背静脉的图像，将静脉的数字图像存贮在计算机***中，将特征值存储。现有技术中的手掌静脉识别方法可分为以下两种：第一种方法是将手掌静脉数据采集后存储在单台计算机中，在单台计算机中进行识别比对，然后返回识别结果，识别成功返回用户信息，未识别出用户则返回识别失败，这种方案的识别算法首先需要对手掌静脉设备采集而来的静脉图像数据进行特征值提取，转化为数字信息后，再利用计算机设备中的中央处理器(Central Processing Unit，CPU)进行匹配运算；第二种方法是将识别程序与手掌静脉数据库移到远程服务器，单机终端通过局域网或广域网连接至远程服务器，当需要进行手掌静脉识别任务时，单机终端采集图像并提取特征后，通过网络上传至远程识别服务器，服务器匹配计算后将识别结果发送至终端或其他预设的***。The palm vein, as the name suggests, is the palm vein. Palm vein recognition is a type of vein recognition, which belongs to biometrics. The palm vein recognition system first obtains a personal palm vein distribution map through a vein recognition instrument, extracts feature values from the palm vein distribution map according to a special comparison algorithm, and uses near-infrared charge lotus roots. Charged Coupled Device (CCD) camera acquires images of veins in fingers, palms, and dorsal hands, stores digital images of veins in a computer system, and stores feature values. The palm vein recognition methods in the prior art can be divided into the following two types: The first method is to collect palm vein data and store it in a single computer, perform recognition and comparison in a single computer, and then return the recognition result and recognize The user information is returned successfully, and the recognition failure is returned if the user is not recognized. The recognition algorithm of this solution first needs to extract the feature value of the vein image data collected from the palm vein device, convert it into digital information, and then use the computer equipment. The central processing unit (CPU) performs matching operations; the second method is to move the recognition program and the palm vein database to a remote server. The stand-alone terminal is connected to the remote server through a local area network or a wide area network. When palm vein recognition tasks are required After collecting images and extracting features, the stand-alone terminal uploads them to the remote identification server through the network. After the server matches the calculation, the identification results are sent to the terminal or other preset systems.

发明人发现现有技术中至少存在如下问题：第一种方法的识别的速度受数据库中数据样本总量大小与计算机CPU性能高低的影响，由于手掌静脉数据的大小相对于指纹与人脸特征数据来说均高出数倍，因此当CPU主频计算性能不高、待比对识别的样本又较多时，第一种方法无法快速准备计算出匹配结果，因此该方法也无法适用于大规模的用户场景；第二种方法中，由于每台服务器能够处理的数据是有限的，且能够比对生物信息的服务器较为昂贵，导致第二种方法在大规模数据场景下应用时，需要相应的增加服务器的数量，从而导致该种方法的成本较高。The inventor found that at least the following problems exist in the prior art: the speed of the first method of recognition is affected by the size of the total number of data samples in the database and the performance of the computer CPU, because the size of the palm vein data is relative to the fingerprint and facial feature data Generally speaking, it is several times higher, so when the CPU frequency calculation performance is not high, and there are many samples to be compared and identified, the first method cannot quickly prepare to calculate the matching result, so this method cannot be applied to large-scale User scenario; in the second method, because the data that each server can process is limited and can be more expensive than the server for biological information, the second method needs to be increased when applied in large-scale data scenarios The number of servers, which leads to higher cost of this method.

具体实施方式detailed description

为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following describes the embodiments of the present application in detail with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in the embodiments of the present application, many technical details are proposed in order to make the reader better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this application can be realized.

本申请的第一实施方式涉及一种方法，具体流程如图1所示，包括：The first embodiment of the present application relates to a method. The specific process is shown in FIG. 1 and includes:

S101：获取终端节点采集的生物信息。S101: Obtain the biological information collected by the terminal node.

关于步骤S101，具体的说，本实施方式中终端节点采集的生物信息可以为手掌静脉信息。静脉是导血回心的血管，起于毛细血管，止于心房，表浅静脉在皮下可以看见。掌静脉，顾名思义，就是手掌内静脉。掌静脉识别是静脉识别的一种，属于生物识别，掌静脉识别***就是首先通过静脉识别仪取得个人掌静脉分布图，从掌静脉分布图依据专用比对算法提取特征值，通过近红外线CCD摄像头获取手指、手掌、手背静脉的图像，将静脉的数字图像存贮在计算机***中，将特征值存储。静脉比对时，实时采取静脉图，提取特征值，运用先进的滤波、图像二值化、细化手段对数字图像提取特征，同存储在主机中静脉特征值比对，采用复杂的匹配算法对静脉特征进行匹配，从而对个人进行身份鉴定，确认身份。Regarding step S101, specifically, the biological information collected by the terminal node in this embodiment may be palm vein information. A vein is a blood vessel that leads back to the heart, starting in capillaries and ending in the atrium, and the superficial vein can be seen under the skin. The palm vein, as the name suggests, is the palm vein. Palm vein recognition is a type of vein recognition. It belongs to biometrics. The palm vein recognition system first obtains the personal palm vein distribution map through the vein recognition instrument, extracts the characteristic values from the palm vein distribution map according to a special comparison algorithm, and uses a near-infrared CCD camera Acquire images of veins in fingers, palms, and dorsal hands, store digital images of veins in a computer system, and store feature values. During vein matching, the vein map is used in real time to extract feature values, and advanced filtering, image binarization, and refinement are used to extract features from digital images. The features are compared with the vein feature values stored in the host, and a complex matching algorithm is used. Vein features are matched to identify individuals and confirm their identities.

需要说明的是，本实施方式中的终端节点是存储有一定数量的生物信息的终端节点，中央服务器会将自身存储的生物信息发送至各个终端节点进行存储，且为了避免数据冗余，各个终端服务器存储的生物信息均不相同(即所有的终端节点存储的生物信息数量之和即为中央服务器存储的生物信息总量)。It should be noted that the terminal node in this embodiment is a terminal node that stores a certain amount of biological information. The central server sends the biological information stored by itself to each terminal node for storage. In order to avoid data redundancy, each terminal The biological information stored by the server is not the same (that is, the sum of the amount of biological information stored by all terminal nodes is the total amount of biological information stored by the central server).

S102：将采集的生物信息发送至各个终端节点进行生物信息比对。S102: Send the collected biological information to each terminal node for biological information comparison.

关于步骤S102，具体的说，中央服务器会将采集的生物信息发送给所有的终端节点进行比对。Regarding step S102, specifically, the central server sends the collected biological information to all terminal nodes for comparison.

S103：在接收到各个终端节点中的一个终端节点发送的比对成功信息后，向发送比对成功信息的终端节点发送与采集的生物信息匹配的注册用户信息。S103: After receiving the comparison success information sent by one of the terminal nodes, send the registered user information that matches the collected biological information to the terminal node that sends the comparison success information.

关于步骤S103，具体的说，在步骤S101中提及：“中央服务器会将自身存储的生物信息发送至各个终端节点进行存储，且为了避免数据冗余，各个终端服务器存储的生物信息均不相同”，可以理解的是，当各个终端节点均接收到中央服务器发送的采集的生物信息后，本身就存储有该采集的生物信息的终端节点的比对速度必定是最快的，当这个终端节点比对成功后，会向中央服务器发送所述比对成功信息，中央服务器在接收到所述比对成功信息后会向发送比对成功信息的终端节点发送与采集的生物信息匹配的注册用户信息。需要说明的是，本实施方式中的注册用户信息可以为用户的支付信息，如在地铁口的自贩柜，用户在支付时可以在自贩柜的特定位置识别手掌静脉信息，中央服务器将该手掌静脉信息发送至各个终端节点并进行比对完成后，会向该自贩柜(即终端节点)发送该用户的支付信息，以便于在用户购物后扣款。Regarding step S103, specifically, it is mentioned in step S101: "The central server will send the biological information stored by itself to each terminal node for storage, and in order to avoid data redundancy, the biological information stored in each terminal server is different. "It is understandable that after each terminal node receives the collected biological information sent by the central server, the comparison speed of the terminal node that itself stores the collected biological information must be the fastest when this terminal node After the comparison is successful, the comparison success information will be sent to the central server. After receiving the comparison success information, the central server will send the registered user information that matches the collected biological information to the terminal node that sends the comparison success information. . It should be noted that the registered user information in this embodiment may be the user's payment information, such as a vending machine at the subway entrance. When paying, the user can identify palm vein information at a specific location of the vending machine. The central server will After the palm vein information is sent to each terminal node and the comparison is completed, the user's payment information will be sent to the self-sales counter (ie, terminal node) to facilitate deduction after the user makes a purchase.

值得一提的是，本实施方式中的终端节点可以为自贩柜中的子服务器，当某个用户在某个自贩柜购物的次数较多时，中央服务器可以将该用户的手掌静脉信息发送至该自贩柜的子服务器中进行存储，以便于该用户下次在该台自贩柜购物时，自贩柜能够快速识别出用户的手掌静脉信息，避免了用户的等待时间，提高了用户的使用体验。It is worth mentioning that the terminal node in this embodiment may be a sub-server in a vending cabinet. When a user makes a lot of purchases in a vending cabinet, the central server may send the palm vein information of the user Stored in the sub-server of the self-sales cabinet, so that the next time the user purchases in the self-sales cabinet, the self-sales cabinet can quickly identify the user's palm vein information, avoiding the user's waiting time and improving the user Experience.

更优的，如果遇到网络异常等特殊情况，中央服务器会设置一个预设时间(如2秒)，在2秒内没有接收到终端节点发送的比对成功信息后，则发送识别失败信息，避免了用户漫长的等待。也就是说，在所述向发送比对成功信息的终端节点发送与所述采集的生物信息匹配的注册用户信息之前，还包括：判断是否在预设时间内接收到所述比对成功信息，若是，则再执行所述向发送比对成功信息的终端节点发送与所述采集的生物信息匹配的注册用户信息；若不是，则向所述终端节点发送识别失败信息。More preferably, if you encounter a special situation such as a network abnormality, the central server will set a preset time (such as 2 seconds). If you do not receive the comparison success message sent by the terminal node within 2 seconds, you will send a recognition failure message. Avoid long waiting for users. That is to say, before sending the registered user information matching the collected biological information to the terminal node that sends the comparison success information, it further includes: determining whether the comparison success information is received within a preset time, If yes, then execute the sending of the registered user information matching the collected biological information to the terminal node that sends the comparison success information; if not, send the identification failure information to the terminal node.

本申请的第二实施方式涉及一种生物信息识别方法，第二实施方式是在第一实施方式的基础上做了进一步的改进，具体改进之处在于：在第二实施方式中，在所述获取终端节点采集的生物信息之前，还包括：获取并存储待注册用户注册的生物信息；将所述注册的生物信息发送至满足预设条件的终端节点进行存储。通过此种方式，使得待注册用户的生物信息能够存储在满足预设条件的终端节点内，有效的避免了某一终端节点因存储的数据过多而导致生物信息的比对速度变慢，进一步提高了生物识别的速度。The second embodiment of the present application relates to a biological information recognition method. The second embodiment is a further improvement based on the first embodiment. The specific improvement lies in: In the second embodiment, the Before acquiring the biological information collected by the terminal node, the method further includes: acquiring and storing the biological information registered by the user to be registered; and sending the registered biological information to the terminal node satisfying the preset condition for storage. In this way, the biometric information of the user to be registered can be stored in the terminal node that meets the preset conditions, which effectively avoids the slowdown of the comparison speed of the biometric information caused by a certain terminal node due to too much stored data. Increased the speed of biometrics.

本实施方式的具体流程如图2所示，包括：The specific process of this embodiment is shown in FIG. 2 and includes:

S201：获取并存储待注册用户注册的生物信息。S201: Acquire and store the biometric information registered by the user to be registered.

关于步骤S201，具体的说，本实施方式中的生物信息可以为待注册用户的手掌静脉信息，待注册用户可以通过应用程序(Application，APP)或其他方式将自身的手掌静脉信息传输到中央服务器，中央服务器在接收到该用户的手掌静脉信息后，会存储手掌静脉信息以及与所述手掌静脉信息对应的用户信息(如身份证号、支付账号等)。Regarding step S201, specifically, the biological information in this embodiment may be palm vein information of the user to be registered, and the user to be registered may transmit their palm vein information to the central server through an application (APP, APP) or other methods After receiving the palm vein information of the user, the central server will store the palm vein information and the user information corresponding to the palm vein information (such as ID card number, payment account number, etc.).

S202：将注册的生物信息发送至满足预设条件的终端节点进行存储。S202: Send the registered biological information to a terminal node that meets a preset condition for storage.

关于步骤S202，具体的说，本实施方式中将注册的生物信息发送至满足预设条件的终端节点进行存储，可以为：获取所述各个终端节点的存储量；将所述注册的生物信息发送至存储量最小的终端节点进行存储。可以理解的是，为了达到各个终端节点的均衡发展，本实施方式通过负载均衡的技术方案，使得注册的手掌静脉信息均匀的落地在各个终端节点上，从而达到比对服务时性能的均衡平摊效果。也就是说，中央服务器能够得知各个终端节点当前的存储量，在有新的用户注册(即有新的手掌静脉信息)时，中央服务器会将新的手掌静脉信息发送至存储量最小的终端节点进行存储，有效的避免了某一终端节点因存储的数据过多而导致生物信息的比对速度变慢，进一步提高了生物识别的速度。Regarding step S202, specifically, in this embodiment, sending the registered biological information to a terminal node that meets a preset condition for storage may be: acquiring the storage amount of each terminal node; sending the registered biological information To the terminal node with the smallest storage capacity for storage. It can be understood that, in order to achieve balanced development of each terminal node, this embodiment uses a load balancing technical solution to make the registered palm vein information evenly land on each terminal node, so as to achieve a balanced distribution of performance when comparing services effect. In other words, the central server can know the current storage capacity of each terminal node. When there is a new user registration (that is, there is new palm vein information), the central server will send the new palm vein information to the terminal with the smallest storage capacity The storage of the node effectively avoids the slowdown of the comparison speed of the biological information caused by too much stored data at a certain terminal node, which further improves the speed of biological identification.

值得一提的是，由于网络存在一定的不稳定因素，若由于网络原因导致中央服务器与存储量最小的终端节点无法通信，中央服务器会每隔指定时间内发起重试服务，直到完成服务(即将手掌静脉信息发送至存储量最小的终端节点进行存储)。也就是说，本实施方式在所述获取所述各个终端节点的存储量之后，还包括：判断与所述生物信息存储量最小的终端节点通信是否正常，在判定正常时，则再执行所述将所述注册的生物信息发送至存储量最小的终端节点进行存储；在判定不正常时，每隔预设时间段向所述存储量最小的终端节点发送通信连接请求，直至与所述存储量最小的终端节点正常通信。可以理解的是，本实施方式中的预设时间段可以根据实际需求设定，并不会影响本实施方式的技术效果。It is worth mentioning that due to certain unstable factors in the network, if the central server cannot communicate with the terminal node with the smallest storage due to network reasons, the central server will initiate a retry service every specified time until the service is completed (that is, Palm vein information is sent to the terminal node with the smallest storage for storage). That is to say, after acquiring the storage capacity of each terminal node, this embodiment further includes: determining whether the communication with the terminal node with the smallest storage amount of the biological information is normal; Send the registered biological information to the terminal node with the smallest storage capacity for storage; when it is determined that it is abnormal, send a communication connection request to the terminal node with the smallest storage capacity every preset time period until it reaches the storage capacity The smallest terminal node communicates normally. It can be understood that the preset time period in this embodiment can be set according to actual needs, and does not affect the technical effect of this embodiment.

更优的，为了使中央服务器能够快速而精准的得知哪个终端节点的通信异常，本实施方式的中央服务器在获取并存储待注册用户注册的生物信息之后，还会获取等待处理信息；在判定与所述生物信息存储量最小的终端节点通信时，则再执行所述将所述注册的生物信息发送至存储量最小的终端节点进行存储，并删除所述等待处理信息；在判定不正常时，每隔预设时间段向所述存储量最小的终端节点发送通信连接请求，直至与所述存储量最小的终端节点正常通信。也就是说，中央服务器在接收到待注册用户注册的生物信息之后，会获取等待处理信息，当中央服务器与存储量最小的终端节点通信正常时，会将注册的生物信息发送至该终端节点并删除该等待信息，当中央服务器与存储量最小的终端节点通信异常时，即无法将注册的生物信息发送至该终端节点，等待处理信息会一直存在，换句话说，中央服务器会将具有等待处理信息的终端节点作为通信异常的终端节点，并每隔预设时间段向其发送通信连接请求，通过此种方式，使得中央服务器在众多终端节点中能够快速的找到通信异常的终端节点，有效的提高了中央服务器的工作效率。More preferably, in order to enable the central server to quickly and accurately know which terminal node's communication is abnormal, the central server of this embodiment, after acquiring and storing the biometric information registered by the user to be registered, will also acquire the information waiting to be processed; When communicating with the terminal node with the smallest storage amount of biological information, execute the sending of the registered biological information to the terminal node with the smallest storage amount for storage, and delete the waiting processing information; when it is determined that it is abnormal , Send a communication connection request to the terminal node with the smallest storage amount every preset time period until normal communication with the terminal node with the smallest storage amount. In other words, after receiving the biometric information registered by the user to be registered, the central server will obtain the waiting processing information. When the central server communicates normally with the terminal node with the smallest storage capacity, it will send the registered biometric information to the terminal node and Delete the waiting information. When the communication between the central server and the terminal node with the smallest storage capacity is abnormal, the registered biological information cannot be sent to the terminal node. The waiting processing information will always exist. In other words, the central server will have the waiting processing The terminal node of the information is regarded as the terminal node of abnormal communication, and sends a communication connection request to it every preset time period. In this way, the central server can quickly find the terminal node of abnormal communication among many terminal nodes. Improve the working efficiency of the central server.

S204：将采集的生物信息发送至各个终端节点进行生物信息比对。S204: Send the collected biological information to each terminal node for biological information comparison.

S205：在接收到各个终端节点中的一个终端节点发送的比对成功信息后，向发送比对成功信息的终端节点发送与采集的生物信息匹配的注册用户信息。S205: After receiving the comparison success information sent by one of the terminal nodes, send the registered user information that matches the collected biological information to the terminal node that sends the comparison success information.

本实施方式中的步骤S203至步骤S205与第一实施方式中的步骤S101至步骤S103类似，为了避免重复，此处不再赘述。Steps S203 to S205 in this embodiment are similar to steps S101 to S103 in the first embodiment. In order to avoid repetition, they will not be repeated here.

为了便于理解，下面对本实施方式中应用该生物信息识别方法的***、以及该生物识别方法的具体流程进行详细说明：For ease of understanding, the following describes the system for applying the biological information recognition method in this embodiment and the specific flow of the biological recognition method in detail:

整体***包含：去中心化分布式核心***(即中央服务器)、分布式***的可靠协调***(Zookeeper)统一服务、各个终端的节点服务、数据服务(包含关系型数据库管理***MYSQL、高性能的开源的key-value数据库REDIS)、比对运营监控***、统一网关接口。The overall system includes: decentralized distributed core system (ie central server), distributed system reliable coordination system (Zookeeper) unified service, node service of each terminal, data service (including relational database management system MYSQL, high performance Open source key-value database (REDIS), comparison operation monitoring system, unified gateway interface.

注册的业务流程上采用最终一致性方案，注册数据会落地在中央数据库(MYSQL)和对应的终端节点上(REDIS)，由于是网络存在一定的不稳定性因素，所以注册流程中保证中央数据库成功落地后即可返回成功，对于客户端来说是透明的，后续的终端节点，会通过最终一致性来完成数据的完整性和一致性。The final consistency scheme is adopted in the business process of registration, and the registration data will land on the central database (MYSQL) and the corresponding terminal node (REDIS). Due to the instability of the network, the registration process guarantees the success of the central database After landing, it can return to success, which is transparent to the client. The subsequent terminal nodes will complete the data integrity and consistency through the final consistency.

具体的方案是：注册数据和注册业务状态数据在事务下完整的落地中央数据库，根据负载均衡的方案选择其中的一个终端节点进行数据落地，终端和核心***都会注册到 Zookeeper统一服务上，进行消息通知，通过分布式***的可靠协调***(zookeeper，ZK)节点的消息服务来完成终端节点的数据落地，并通知删除对应的注册业务状态数据；若由于网络原因导致无法通信，核心***会每隔指定时间内发起重试服务，直到完成服务。The specific plan is: the registration data and registration business status data are completely landed in the central database under the transaction. According to the load balancing scheme, one of the terminal nodes is selected for data landing. Both the terminal and the core system will register with the Zookeeper unified service for messaging Notification, through the message service of the reliable coordination system (zookeeper, ZK) node of the distributed system to complete the data landing of the terminal node, and notify the deletion of the corresponding registered business status data; if the communication cannot be due to network reasons, the core system will The retry service is initiated within a specified time until the service is completed.

比对服务提供的方案采用同步+异步的方式进行，同步采集到认证手脉信息发起比对请求，分发到各个终端节点进行比对服务，Zookeeper统一服务会统一协调监听机制，一旦有某个终端节点完成比对服务并返回结果后，则同步请求处于等待状态，获取结果后返回客户端，如网络异常等特殊情况，会设置一个超时时间，超过超时时间则直接返回。The scheme provided by the comparison service is carried out in a synchronous + asynchronous manner. The authentication request is collected synchronously to initiate a comparison request, which is distributed to each terminal node for comparison service. The Zookeeper unified service will coordinate the monitoring mechanism uniformly. After the node completes the comparison service and returns the result, the synchronization request is in a waiting state, and returns to the client after obtaining the result. For special circumstances such as network abnormalities, a timeout period will be set, and if the timeout period is exceeded, it will return directly.

2、Zookeeper统一服务，提供整套***统一的协调服务，是***消息通信的核心保障，采用多台部署、主从结构，能完整的不间断的提供7*24的服务；核心***、终端节点、比对运营监都会在Zookeeper统一服务上注册节点信息。2.

It adopts multiple deployment and master-slave structures to provide complete and uninterrupted 7*24 services; core system, terminal nodes, The comparison operation supervisor will register the node information on the Zookeeper unified service.

3、各个终端的节点服务，提供核心的1：N比对服务，在各个终端节点上落地数据到内存数据库REDIS上，用于快速获取到数据进行比对服务。3. The node service of each terminal provides the core 1:N comparison service, and the landing data on each terminal node is transferred to the memory database REDIS, which is used to quickly obtain the data for comparison service.

4、比对运营监控***，监控核心***上注册和比对的数据流量、Zookeeper统一服务提供的节点分布信息、各个终端节点的比对服务分布。4. Compare the operation monitoring system, monitor the data flow registered and compared on the core system, the node distribution information provided by the Zookeeper unified service, and the comparison service distribution of each terminal node.

5、统一网关接口，对外统一提供超级文本传送协议(Hyper Text Transport Protocol，HTTP)/超级文本传送协议安全(Hyper Text Transfer Protocol Secure，HTTPS)服务，采用统一的报文格式，做到接口的统一性和通用性。5. Unified gateway interface, unified provision of Hyper Text Transfer Protocol (HyperTextTransportProtocol, HTTP)/Hypertext Transfer Protocol Security (HyperTextTransferProtocolSecure, HTTPS) service, using a unified message format to achieve the unification of the interface Sex and versatility.
