Introduction The topic of discussion that was proposed by Rachid Hadjidj, Mourad Debbabi*, Hakim Lounis, Farkhund Iqbal, Adam Szporer, Djamel Benredjem was a new technique in uncovering e-mail forensic data for use in a court of law. Different types of cyber crimes performed through e-mail include â€Å"spamming, phising, drug trafficking, cyber bullying, racial vilification, child pornography, sexual harassment, etc.† Suspected e-mail accounts are examined by forensic analysis and data is captured in order to prove crimes in court.

Cyber forensic investigation with respect to e-mails is the collection of credible evidence through analyzing e-mail collections to prosecute criminals. Analytics should include keyword searches, authorship attribution, and computing statistics. The writers of the article have combined social network analysis with these analytics to create a tool that can track who might be accomplices to malicious e-mailing.

With traditional authorship attribution, the writing style of a person is examined by using an entire collection of e-mails without regards to whom they are written. Further more stylometric features are assumed consisten t and not controlled by the writer.
