Data Mining of Social Media Specific Strings for Rapid Forensic Investigation

Abstract

Instant Messengers become an important means of communication. Millions of people. regardless of age, nationality, gender and computer skills, spend a lot of time using them every day. Thus, Social networks already occupied the place of traditional messaging systems of the past. More and more communications are migrating from public chat rooms and private messengers into online Social Networking Sites (SNSs). As cybercrimes mushroom in recent years, more and more digital crime investigations have strong relations to these SNSs. Communications extracted from SNSs can be extremely valuable and useful to all kinds of investigators including forensic investigators. We now apply the spotlight on distinct strings specific to each SNSs and volatile memory analysis and display of any case detail as a key to a successful digital investigation through rapid & improved retrieval performance.
