Abstract
The rapid adoption of Internet of Things (IoT) technology has increased the transmission of digital image data over public networks, particularly in monitoring and sensor-based applications. However, such data exchange is susceptible to security threats, including eavesdropping and unauthorized access, and large data volumes can also degrade network performance. This study aims to design a mechanism for filtering digital image data within IoT networks to ensure that only relevant images are processed and transmitted, while applying RSA encryption to safeguard data during transmission. The methodology includes defining relevance criteria, filtering images based on these criteria, and encrypting selected data using the RSA algorithm. System implementation results indicate that the filtering process significantly reduces network load, and RSA encryption effectively protects data from leakage and third-party attacks during transmission. Overall, the combination of selective filtering and cryptographic protection enhances both security and efficiency in digital image data exchange across IoT networks. Therefore, this approach provides a viable solution for managing and securing digital image data within IoT environments.
