This paper presents a brief review of ciphering methods for secure image communications in the contexts of Internet of Things (IoT) and artificial intelligence. With the rapid advancements in mobile computing and the diversity of public data storing devices, ensuring robust security mechanisms has become a critical area of focus. We acknowledge the importance of historical context and the evolution of encryption/decryption approaches, and we aim to establish a systematic understanding of lightweight image encryption in IoT applications. To this end, a use case for AES image encryption will be highlighted to provide practical insights. Moreover, an abstract ciphering approach is suggested towards limiting the imagerelated de-anonymization attacks which can occur over publicly shared trained image sets.
