what are social networks
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
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
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
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
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
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 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
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.
