A post this week on the CLPEX History forum by Gerrit Volckeryck (Belgium)
exposes what could be the earliest published instance (1863) of the
proposition of use of chemically developed
unique ("infinitely variable") latent prints to prove
a crime (forgery). Gerrit points out publication by Louis Figuier in
the Journal de Toulouse, dated 29/12/1863, of the research of M.

we looked at the importance of knowing our AFIS databases.
George Reis brings us an overview and a request for more information
regarding forensic digital asset management systems.
Forensic Digital Asset Management; An
Overview and Search for More Information
by George Reis
This paper is an outline of ideas that I plan to expand in the coming few
weeks – with your help. Please read this paper, and provide feedback to me
via e-mail at firstname.lastname@example.org or via my survey at:
What is digital asset management? In the simplest of terms, it is the method
we use for archiving and retrieving our digital photos, scans, videos, and
other digital files. It will consist, at minimum, of some sort of hardware
(to store the assets) and some fort of filing method. In more complex
scenarios, it may include secure networks, encrypted files, authentication
software, database integration with other systems, etc.
Solutions range in price from free (except for the cost of the storage –
hard drive space, for example) to tens of thousands of dollars.
The free solutions can provide image security, easy retrieval, image
browsing and a simple interface. Modest priced solutions will include all
this, plus they may include a database of both searchable metadata terms and
low-resolution images. Off the shelf, commercial applications such as
Extensis Portfolio or Canto Cumulus, can also integrate with other databases
using common protocols like SQL. The most expensive solutions are marketed
as “law enforcement solutions” and may include some extras like storing the
files on a hidden drive.
When I consider the options, I often wonder what the considerations are that
users consider when planning their digital asset management and storage
solutions – why they choose one option over another. When I worked for a
police agency, we used the free method, and it worked well from 1992, when
we incorporated it, to the present. I’ve seen other agencies incorporate
systems costing tens of thousands of dollars that don’t seem to offer any
benefit over what we did for free.
There are a few choices to make when storing our images. We need to pick the
media to use, the downloading method (from drag-and-drop to custom windows
that include HASH logging), the level of security, whether to add keywords
to search for images based on crime type, location or photographer, whether
we integrate this system with a records management system, etc.
For images to be used in court, they basically need to represent what they
purport to represent. No requirements exist for special “law enforcement”
security or for software-based authentication. This doesn’t mean that we
don’t need to use good practice, but it does mean that there are many ways
to meet and exceed court requirements.
Whether you currently use a law enforcement solution, a commercial
application, or have simply done it yourself – I would really appreciate
your feedback on either why you have made the choice you have, whether you
are considering something different (and why), and what features are
important to you in making this decision.

QA during the comparison phase - Originals or
by Michele Triplett, King County
The intent of this is to provide thought provoking discussion.
No claims of accuracy exist.
Originals or copies:
How does using a copy affect the comparison process?
Copies of the originals are somewhat degraded from
the original image and this may have an affect on a conclusion.
Conclusions may be possible with originals that aren’t possible with
Latent images can be enhanced through the use of
computer programs. Once an
image is enhanced then additional individualizations can be made that may
not be possible when using the original image.
Copies can be used for comparison purposes and it’s
up to the person doing the comparison to decide if the copy has the quality
needed to be useful.
Answers a and b:
Both of these answers are correct but it’s the examiners
responsibility to use what’s necessary to do a thorough job.
If the appropriate tools cannot be used, for a variety of reasons,
then this should be stated in the result, “Inconclusive – computer
enhancement may aid in arriving at a conclusion”.
I think this is the most accurate answer.
As stated with answers from other questions, it’s important to give
the most comprehensive answer because multiple examiners may be testifying
in the same case. This may not
be known if one of the examiners is testifying for the prosecution and
another examiner is testifying for the defense, therefore it’s wise to
always assume another examiner may be testifying in all of your cases.
