Research on information security mechanism for barrage videos

As the rapid progress of internet and the widespread of Network media, barrage videos are widely favored by the audiences, because of their unique way of interactive and emotional experience. However, porny, brutal and rude words occasionally happen in the barrages. Thus information security in barrage videos has become a serious problem and requires further study. In this paper, the harmful information brought by barrages is first introduced. In addition, three measurements are defined to quantitatively study barrage videos, including the frequency of barrages, the correlation between barrage number and video's rank, and the preference of barrage patterns, followed by numerical statistics and analysis. Finally the information security mechanism for barrage videos is presented, giving executable solutions.
