Randa Aljably, Yuan Tian, Mznah Al-Rodhaan
2020 Security and Communication Networks  
The models could use further information derived from the user's profiles to detect anomalous users.  ...  In this paper, we implement a privacy preservation algorithm that incorporates supervised and unsupervised machine learning anomaly detection techniques with access control models.  ...  In addition, the anomalies are not labeled and they are distributed all over the dataset. Furthermore, it is normal for a user's behavior to evolve and change over time.  ...

Diagnosing Venomous Facebook Applications

K. Saiprasad
2016 International Journal Of Engineering And Computer Science  
Our main contribution is in evolving FRAppE-Facebook's Rigorous Application Evaluator-feasibly the first tool focused on detecting malicious apps on facebook.  ...  The issue is already valid, as we find that at least 13% of apps in our dataset are malicious. So far, the research center has concentrated on detecting malicious posts and campaigns.  ...  Others have proposed a honey-pot-based approach to detect spam accounts on OSNs. Yardi et al. analyzed behavioral patterns among spam accounts in Twitter.  ...

A survey of data mining and social network analysis based anomaly detection techniques

Ravneet Kaur, Sarbjeet Singh
2016 Egyptian Informatics Journal  
Anomalous activities in social networks represent unusual and illegal activities exhibiting different behaviors than others present in the same structure.  ...  Online Social Networks (OSNs) have fetched the interest of researchers for their analysis of usage as well as detection of abnormal activities.  ...  Sometimes, the normal behavior does not result in any network change; then, any neighborhood changes may also predict an anomalous behavior.  ...

Realistic Aspects of Simulation Models for Fake News Epidemics over Social Networks

Quintino Francesco Lotito, Davide Zanella, Paolo Casari
2021 Future Internet  
Moreover, we emphasize that bots dramatically speed up the spreading process and that time-varying engagement and network access change the effectiveness of fake news spreading.  ...  Specifically, we introduce agents with the role of influencers and bots in the model and consider the effects of dynamical network access patterns, time-varying engagement, and different degrees of trust  ...  Data Availability Statement: All results in this paper can be derived from our simulation software, publicly available on GitHub (, accessed on 16 March 2021  ...
