What are Social Networks? • Social Networks are a special kind of network in which people represent nodes and their relationship represent links. • Come in various types and sizes. Medieval analysis of powerful Italian families
Information Available Online • Huge amount of data is generated every second online. • Analysis of this data is not possible without use of powerful algorithms. • Data mining and extraction is crucial to reduce the state space and obtain useful information.
Social Networks in Internal Security • Easy to spread false information online. • Rumors spread like wildfire. • Difficult to control content online due to various factors.
Information Diffusion & Modeling • Diffusion process can be modelled mathematically. • Accuracy of this modeling is fairly high. • Allows us to judge the scale of the information flow.
Influence Maximization & Link Prediction • Determining the most influential nodes in the network is NP-Hard. • Determining future links in a social networks is useful to find out favorable propagation environments. • Process of information spread can produce different influencial nodes and future links. i.e. it is a dynamic process.
Problem of Malinformation • Easy to spread malinformation in social networks. • Can affect large portions of the network if suitable propagators are used. • Can influence the thinking of the people in the network and cause mass uproar which is difficult to control.
Proactive and Reactive Measures • Proactive measures involve actively searching for malicious rumors and denying favorable environments for them to propagate. • Reactive measures involve starting a counter campaign to reverse the thinking of the crowd. • A mix of the 2 methods can be the most effective in controlling the spread of malinformation.
Conclusion & Summary • The problem of malinformation in social networks is crucial to internal security as can be seen from various events in the past. • With the advent of social media as the primary information disseminator, a control must be established so as to not spread vile thinking. • Since freedom of speech must not be breached, this problem can only be stopped prematurely at best.
