Abstract: Big data era facilitates the flow of information, which could, accordingly, increase the risk of data breach. The essay aims at illustrating that the flow of information would pose challenges to privacy by dis-cussing how the personal data that is directly collected and the data generated from pre-existing datasets can result in data breach. The first part analyzes how personal information trades and retreating phenomenon on social media cause the privacy leakage. The second part points out the threat that is presented by the inferred and derived data, which deserves more attention, yet few studies have covered that field.
