The Internet of Things (IoT) is built on a strong internet infrastructure and many wireless sensor devices. Presently, Radio Frequency Identification embedded (RFID-embedded) smart cards are ubiquitous, used for many things including student ID cards, transportation cards, bank cards, prepaid cards, and citizenship cards. One example of places that require smart cards is libraries. Each library, such as a university library, city library, local library, or community library, has its own card and the user must bring the appropriate card to enter a library and borrow material. However, it is inconvenient to bring various cards to access different libraries. Wireless infrastructure has been well developed and IoT devices are connected through this infrastructure. Moreover, the development of biometric identification technologies has continued to advance. Blockchain methodologies have been successfully adopted in various fields. This paper proposes the BlockMetrics library based on integrated technologies using blockchain and finger-vein biometrics, which are adopted into a library collection management and access control system. The library collection is managed by image recognition, RFID, and wireless sensor technologies. In addition, a biometric system is connected to a library collection control system, enabling the borrowing procedure to consist of only two steps. First, the user adopts a biometric recognition device for user authentication and then performs a collection scan with the RFID devices. All the records are recorded in a personal borrowing blockchain, which is a peer-to-peer transfer system and permanent data storage. In addition, the user can check the status of his collection across various libraries in his personal borrowing blockchain. The BlockMetrics library is based on an integration of technologies that include blockchain, biometrics, and wireless sensor technologies to improve the smart library.

基于无线传感器网络的区块链与生物识别集成技术在图书馆管理中的应用

物联网（IoT）建立在强大的互联网基础设施和许多无线传感器设备上。当前，射频识别嵌入式（嵌入式RFID）智能卡无处不在，用于许多方面，包括学生证，交通卡，银行卡，预付卡和公民卡。需要智能卡的地方之一是图书馆。每个图书馆，例如大学图书馆，城市图书馆，地方图书馆或社区图书馆，都有自己的卡，用户必须携带相应的卡才能进入图书馆并借阅材料。但是，携带各种卡来访问不同的库是不方便的。无线基础设施已经得到很好的发展，物联网设备通过该基础设施进行连接。此外，生物识别技术的发展一直在继续。区块链方法论已在各个领域得到成功采用。本文提出了一种基于区块链和指静脉生物识别技术的集成技术的BlockMetrics库，该库被用于图书馆馆藏管理和访问控制系统中。图书馆馆藏由图像识别，RFID和无线传感器技术管理。此外，生物识别系统连接到图书馆馆藏控制系统，从而使借阅过程仅包含两个步骤。首先，用户采用生物特征识别设备进行用户身份验证，然后使用RFID设备执行收集扫描。所有记录都记录在个人借贷区块链中，这是一个点对点传输系统和永久数据存储。此外，用户可以在其个人借用区块链中的各个库中检查其收藏状态。BlockMetrics库基于包括区块链，生物识别技术和无线传感器技术在内的技术集成，以改善智能库。
