Abstract :
A hard disk size of notebook or personal computer is increased as 3 Terabytes. The forensic data including social network such as twitter is over several Petabytes. As the evidence is large scale data, an investigator takes long time to search critical clue which is related a crime. So, high speed of analysis from large scale forensic data is necessary. This paper is concerned with text extraction for forensic data. As file input/output processing of forensic image is used memory interface instead of file, so it makes to reduce the extraction times of text and analysis times of forensic data.
