With the rapid development of the Internet of Things (IoT), the number of IoT devices has increased exponentially. Therefore, we have put forward higher security requirements for the management, transmission, and storage of massive IoT data. However, during the transmission process of IoT data, security issues, such as data theft and forgery, are prone to occur. In addition, most existing data storage solutions are centralized, i.e., data are stored and maintained by a centralized server. Once the server is maliciously attacked, the security of IoT data will be greatly threatened. In view of the above-mentioned security issues, a security transmission and storage solution is proposed about sensing image for blockchain in the IoT. Firstly, this solution intelligently senses user image information, and divides these sensed data into intelligent blocks. Secondly, different blocks of data are encrypted and transmitted securely through intelligent encryption algorithms. Finally, signature verification and storage are performed through an intelligent verification algorithm. Compared with the traditional IoT data transmission and centralized storage solution, our solution combines the IoT with the blockchain, making use of the advantages of blockchain decentralization, high reliability, and low cost to transfer and store users image information securely. Security analysis proves that the solution can resist theft attacks and ensure the security of user image information during transmission and storage.
随着物联网（IoT）的快速发展，物联网设备数量呈指数级增长。因此，我们对海量物联网数据的管理、传输和存储提出了更高的安全要求。然而，在物联网数据的传输过程中，容易出现数据盗窃和伪造等安全问题。此外，现有的大多数数据存储解决方案都是集中式的，即数据由中央服务器存储和维护。一旦服务器受到恶意攻击，物联网数据的安全性将受到极大威胁。鉴于上述安全问题，提出了一种针对物联网中区块链传感图像的安全传输和存储解决方案。首先，该解决方案智能感知用户图像信息，并将这些感知数据划分为智能块。其次，通过智能加密算法对不同的数据块进行加密并安全传输。最后，通过智能验证算法进行签名验证和存储。与传统的物联网数据传输和集中式存储解决方案相比，我们的解决方案将物联网与区块链相结合，利用区块链去中心化、高可靠性和低成本的优势，安全地传输和存储用户图像信息。安全分析证明，该解决方案能够抵御盗窃攻击，并确保用户图像信息在传输和存储过程中的安全。
