The detection of fake social media accounts remains a critical challenge for online platforms.

[T.Karima❶]

Abstract: The detection of fake social media accounts remains a critical challenge for online platforms. This study introduces a novel approach to enhance the detection of these fraudulent profiles by strategically refining the training dataset through a combination of negative selection and K-Means clustering. First, genuine (non-fake) accounts are identified, and a threshold for the mean_followers_following ratio is set based on the 30th percentile of these accounts. K-Means clustering is then applied to the genuine accounts, dividing them into two groups, followed by the removal of genuine accounts furthest from their respective cluster centers to eliminate potential anomalies. Finally, the resulting refined set of genuine accounts is combined with confirmed fake accounts to construct a higher-quality, more representative training dataset. This carefully curated dataset, achieved through this multi-step negative selection process, is designed to improve the performance of subsequent machine learning classification models in accurately identifying fake social media accounts. reformulez l'astract pour aoujoutez dans un article

Résumé : La détection des comptes sociaux fictifs constitue un défi majeur pour les plateformes en ligne. Cette étude propose une approche novatrice visant à améliorer la détection de ces profils frauduleux, en affinant stratégiquement l'ensemble de données d'apprentissage à travers une combinaison de sélection négative et de clustering K-Means. Tout d'abord, les comptes authentiques (non-fake) sont identifiés, et un seuil pour le ratio moyenne_abonnés_suivis est défini sur la base du 30e percentile de ces comptes. Le clustering K-Means est ensuite appliqué aux comptes authentiques, permettant de les diviser en deux groupes. Les comptes authentiques les plus éloignés de leurs centres de cluster respectifs sont ensuite éliminés, afin d'éliminer les anomalies potentielles. Enfin, l'ensemble d'acteurs authentiques ainsi affiné est combiné avec les comptes confirmés comme faux, afin de constituer un ensemble de données d'apprentissage de qualité supérieure et plus représentatif. Cet ensemble de données soigneusement curé, obtenu grâce à ce processus de sélection négative en plusieurs étapes, vise à améliorer la performance des modèles de classification par apprentissage automatique dans l'identification précise des comptes sociaux fictifs.

je veux réduire cet introduction Social networks have become essential applications on
mobile devices, seamlessly integrated into our daily lives.
These platforms connect users globally, allowing for the
sharing of diverse content such as videos, photos, and
messages. However, with the rapid growth of social networks
comes a significant challenge: the rise of fake accounts. These
fraudulent profiles threaten the integrity and security of social
media platforms, often being used for malicious activities like
spreading misinformation, identity theft, and fraud.
A typical social media account consists of visible content
that users engage with and hidden content stored on servers.
The visible stored data contain the user's name, his status, his
personal information, his posts, some photos which can be
avatar or real ones, information about his social network
multimedia, geolocation information, tags, etc. Also, other
hidden information or deleted information which still stored,
meta data about the used browser, operation system, posts and
comments, cookies, and so on are available on the server [1].
As online interactions continue to grow, the rise of fake
profiles has become a serious concern. The detection and
removal of these fraudulent accounts are crucial to ensuring a
safe and trustworthy environment for users.
Over the past two decades, the growth of fake profiles has
kept pace with the expansion of social networks. Several types
of fraudulent profiles have been identified, including
compromised accounts, cloned profiles, fake accounts for
advertising or spam, automated bots, sock puppets, and Sybil
accounts. Each type poses specific challenges for social media
platforms [2].
Traditional detection methods, like rule-based systems and
manual inspections, are losing their effectiveness as creators
of fake profiles use increasingly sophisticated tactics.
Consequently, artificial intelligence (AI) especially machine
learning has emerged as a crucial tool in identifying and
countering these fraudulent accounts. AI excels at recognizing
complex patterns and detecting anomalies that conventional
methods frequently miss [3][4].
The concept of negative selection, inspired by the immune
system's natural ability to distinguish between authentic and
harmful entities, offers an effective approach for detecting
fake profiles. This method utilizes representative training data
to build models that can accurately identify fraudulent
accounts. When combined with machine learning, negative
selection creates a robust and adaptable system, significantly
improving the detection and mitigation of fake profiles on
social media platforms [5].
This study investigates the use of machine learning, with
a focus on the negative selection method, to detect fake
profiles on social media platforms like Instagram. Various
machine learning models, including Random Forest, Support
Vector Machine (SVM), Decision Tree, Logistic Regression,
Artificial Neural Networks (ANN), are applied in combination
with the negative selection technique. The results from this
integrated approach demonstrate its effectiveness in
identifying fraudulent accounts. The subsequent sections will
explore the methodology, results, and broader implications,
showcasing the potential of this advanced model to tackle the
growing problem of fake profiles.

Another study [13] compares traditional machine learning techniques with deep learning models for detecting fake profiles on social networks. The findings show that deep learning models like LSTM perform exceptionally well with larger datasets, while traditional methods like XGBoost are more effective for smaller datasets. Both approaches achieved an accuracy rate of 97%, offering valuable insights into best practices for detecting fraudulent accounts depending on dataset size.
The study [14] developed a machine learning model based on image classification to detect fake accounts on the X platform (formerly Twitter). Tested on a dataset of 15,000 accounts, the model achieved an accuracy rate of over 92%, highlighting its effectiveness in enhancing social media security.
In another study [15], a method for detecting fake social media profiles was introduced, utilizing a majority voting system that combines several machine learning algorithms, such as Decision Trees, XGBoost, and Random Forest. This integrated approach achieved excellent results, with an accuracy, precision, recall, and F1-score of 99.12%, making it a highly effective solution for improving social media security.
The research [16] assessed the performance of various machine learning models, including SVM, K-Nearest Neighbors (KNN), Random Forest (RF), and Artificial Neural Networks (ANN), in detecting fake accounts on social networking platforms. By comparing the accuracy of these models across different datasets, the study offers valuable insights into enhancing the security and reliability of social platforms in identifying fraudulent profiles.

During the preprocessing phase, we generated two new features from the existing 'num_followers' and 'num_following' columns:
• sum_followers_following: This feature represents total user engagement by summing the number of followers and following for each user.
• mean_followers_following: This feature calculates the average number of followers and following, providing a normalized measure of user engagement.
These newly created features help enhance the model's ability to detect patterns related to user behavior.
Negative selection
In this approach, negative selection is applied to improve the detection of fake social media accounts. The process begins by identifying and isolating non-fake accounts, which act as negative examples. A threshold is set for the mean_followers_following feature, based on the 30th percentile of these negative examples. Initially, any negative examples exceeding this threshold are removed. The remaining data is then processed through K-Means clustering, which separates it into two clusters. The cluster centers are identified, and the mean distance to these centers is calculated. This distance acts as an additional filtering threshold, eliminating the most distant negative examples to further refine the dataset. In the final step, the remaining filtered negative examples are combined with the positive examples (fake accounts) to form a new, more representative training dataset...
