The e-discovery problem by Jason R. Baron

This video contains Jason R. Baron, the Director of Litigation of the National Archives and Records Administration (USA) discussing the general problem of electronic discovery, and in particular, the problems of information retrieval in the context of search over billions of documents.

If you are in any way involved in searching for information in a legal context, it is fascinating stuff.

Follow up paper on the AFF4 evidence container to be presented at 6th IFIP WG 11.9 International Conference on Digital Forensics

I posted earlier about a new forensic container format being created by myself, Michael Cohen, and Simson Garfinkel. A paper describing the work was presented at DFRWS 2009 by Michael.

Michael and I have recently extended and refined the container format to support describing the provenance of information and data, and more accurate description of evidence characteristics. A paper describing this work, titled ‚ÄúRefining the AFF4 evidence container for provenance and accurate data representation‚ÄĚ, has been accepted for presentation at the 6th Annual IFIP WG 11.9 conference on Digital Forensics.

The abstract follows:

It is well acknowledged that there is a pressing need for a general solution to the problem of storage of digital evidence, both in terms of copied bit-stream images and general information which describes the images  and  surrounding  context  of  the  case.  In  a  prior  paper,  the  authors  introduced  the  AFF4 evidence container format, focusing in particular on the description of the efficient and layered bitstream storage  architecture,  a  general  approach  to  representing  arbitrary  information,  and  a  compositional approach  to  managing  and  sharing  evidence.  In  this  paper  we  describe  our  work  refining  the representation  schemes  embodied  in  the  new  format,  addressing  the  accurate  representation  of discontiguous data and description of the provenance of both data and information.
