The Analysis of Visual Forensics in Cloud Computing Environment

New characteristics of cloud computing network environment put forward new requirements of electronic forensics,such as positioning key evidence from big data fast and accurately, analyzing the correlation between evidences, and presenting the results of analysis humanely, which will be the new aspect of research. First, forensics technology new features and challenges of cloud computing network were analyzed. Second, based on the research of integrate framework of cloud forensics, the concept of visual evidence collection and visualization of data object representation were put forward, the data fusion technology was introduced, and visual cloud forensics of evidence was made operable by Web interaction technology. Finally, the forensics process in cloud environment was elaborated in details. The research aims at performing new techniques and applications of electronic evidence collection in a complex cloud environment. Visual evidence collection methods could assist forensic analyzing data and locating the key evidence from huge amounts of data quickly. Visual forensics in cloud environment will greatly improve the work efficiency of forensics, having certain research value. Keywords-Cloud computing; Electronic forensics; Data fusion; Visualization
