The synthesis of Large Language Models (LLMs) with the Internet of Cloud (IoC) ecosystems creates multiple opportunities across diverse domains such as healthcare, finance, and smart cities. This study explores the combination of these technologies, focusing on their ability to profile authors and the associated privacy challenges. We conducted two interesting experiments using real data from the Blog Authorship Corpus and the Reddit Self-Reported Depression Diagnosis (RSDD). Then we evaluated the capabilities of two well-known LLMs which are the ChatGPT-4o and Llama 3-70B, in identifying sensitive user demographic data such as gender, age, profession, and psychological conditions. Our findings highlight both the strengths and limitations of these LLMs, with ChatGPT achieving higher reliability across tasks but demonstrating biases and ethical concerns. Moreover, key insights indicate that while LLMs improve precision and adaptability in textual data analysis, they also increase the potential risks of detecting profiling in sensitive contexts. This research highlights the urgency of implementing robust privacy-preserving strategies to mitigate ethical risks and social impacts. Finally, it presents all the useful findings from the two experiments and then provides a detailed analysis of the results by comparing the two LLMs used.
