Abstract

FILES are the most important sources of information presentation in various formats such as texts, audio, video, images, web pages, etc. … ; (in-depth) analysis of FILES for the purpose of recognition and investigating their unique properties (or characteristics) is one of the most significant issues in the field of personal security safety, information security, file-type identification, codes structuration analysis etc… . Statistical analytic methodology of working on the binary FILES contents based on the N-GRAM MODEL has been opted for in the present paper in order to full investigate all the different aspects of a file’ s range of characteristics. Moreover, to reduce down the calculations volume and the N-GRAM MODEL peculiar to the needed amount of memory, use has been made of WORD CLUSTERING. Later on analysis has been conducted on both FILES’ contents in two states of “ blocking” and “ full” : it is to be noted that in the “ full” case such characteristics as Chi-square, Auto-correlation, Weighted term frequency-Inverse document frequency (TF-IDF), FRACTAL DIMENSION etc … have been brought under comprehensive study; while in the “ blocking” case, other properties like the ENTROPY RATE, the distance, etc … have been delved into. The gained results indicate that the extracted characteristics in the first method could well easily reflect the unique properties belonging to jpg, mp3, swf and html FILES; and in the second method, are able to clearly well reflect doc, html and pdf FILES properties
