摘要

This paper provides evidence of a feature of Hard-Disk Drives (HDDs), that wecall File System Genome. Such a feature is originated by the areas where (onthe HDD) the file blocks are placed by the operating system during theinstallation procedure. It appears from our study that the File System Genomeis a distinctive and unique feature of each indi- vidual HDD. In particular,our extensive set of experiments shows that the installation of the sameoperating system on two identical hardware configurations generates twodifferent File System Genomes. Further, the application of sound informationtheory tools, such as min entropy, show that the differences between two FileSystem Genome are considerably relevant. The results provided in this paperconstitute the scientific basis for a number of applications in various fieldsof information technology, such as forensic identification and security.Finally, this work also paves the way for the application of the highlightedtechnique to other classes of mass-storage devices (e.g. SSDs, Flash memories).
