Enhancing Fake Profile Detection in the Age of LLM’s

In the new digital world, social media platforms have been added to the modern communication, networking and information sharing. Neverthe- less, these platforms have also faced tremendous expansion, which has, in turn, resulted in a surge of counterfeit and artificial intelligence-generated accounts that pose some of the most severe cyber security risks, including identity theft, spread of misinformation, phishing, and internet fraud. The conventional fraud fake profile detection techniques greatly depend on either manual validation process, rule-based techniques, or constrained analysis of profile characteristics like profile images, user-names, and frequency of activity. Such methods cannot identify com- plex fake profiles made with the help of high-quality Artifi- cial Intelligence technologies, especially Large Language Models (LLMs) that are capable of coming up with extremely realistic biographies, exchanges, and behavioral patterns. In response to these issues, this study gives a proposal of an intelligent framework of fake profile detection that combines Ma- chine Learning (ML), Natural Language Processing (NLP), and graph- based analysis. The system examines various dimensions of user profiles such as metadata capabilities, behavioral features and textual data. Machine learning algorithms are trained with struc- tured profile characteristics including the number of followers, following behavior, profile activity, and account characteristics that determine genuine and suspicious profiles. Moreover, NLP algorithms are used to deal with textual information like user biographies to identify linguistic and automated textual patterns usually produced by a machine-learning system. Moreover, the correlation between profiles is represented by the graph-based networks that enable the creation of clusters of coordinated or suspicious accounts. This setup (which is multi-layered) allows better detection, better adapt- ability to emerging AI-generated content, and helps to bolster online platform security and digital confidence in the age of Large Language Models.
