Files stored on digital media are broken into smaller blocks prior to
storage. Most of the time these blocks are stored sequentially on the
media. Increasing sizes of files and complexity of their format often
lead to fragmentation in the sequences of blocks written to media. For
example, photo and video files stored in a memory card of a camera are
often fragmented. Another example is email inbox files stored on hard
drives are fragmented. Recovering fragmented files from a media is a
challenge faced by digital forensics and data recovery. This project
formally examines fragmentation and develop practical algorithms to
recover deleted files. The algorithms and methods developed are
independent of operating systems, file systems, or digital media.
The participants of this research project founded Digital Assembly with seed funding from the National Science Foundation and NYSTAR through the CATT at Polytechnic Institue of NYU to commercialize the research ideas. The company has successfully launched two products, Adroit Photo Recovery and Adroit Photo Forensics. Digital Assembly and the research work was recently featured on the New York Times.
