SDOCS Trusts Classified Documents to dtSearch
|
“I
particularly like the dtSearch technical
support staff.”

Technadyne Engineering Consultants, Inc.,
based in Albuquerque, New Mexico, provides high
caliber technical and administrative consulting
services to U.S. government and state agencies,
prime government contractors, national laboratories,
utilities, private, and industrial organizations.
Officially classified as a small business, Technadyne
has successfully completed over $25 million worth
of Professional and Technical Support Services
(PTSS) over the past five years and has access
to some of the finest expertise in the business.
A number of Technadyne employees helped develop
the Classified Document Control System (CDOCS)
while on contract to Sandia National Laboratories
(www.sandia.gov) over the past few years. When
Sandia offered to "Tech-Transfer" CDOCS
to a private company, Technadyne obtained the
license, and now offers CDOCS as SDOCS –
the Secure Document Control System. The same personnel
who worked on CDOCS under contract to Sandia now
support CDOCS users, and enhance SDOCS for new
private and government customers.
Current classified and unclassified document management
systems require a tremendous amount of space and
extensive manpower to track, inventory, and protect
documents. The main problem, however, is the actual
handling of the paper. Most paper systems suffer
from the cost of searching for and recovering
the information on the paper. The purpose of the
Secure Document Control System (SDOCS) is to eliminate
the need for paper by scanning and storing images
of pages on a personal computer using high density
optical media (WORM, Read/Write, or CD-ROM) or
high density, high speed magnetic media. By saving
images on the computer, manpower and space requirements
are reduced, the chance of compromise is diminished,
and the information is more readily available
to the authorized user.
The SDOCS system consists of a personal computer,
a high-resolution video display (1600 x 1200 pixels),
a high-speed scanner (40 pages per minute), and
a laser printer. Images are stored on large hard
drives (8GBt) and can be archived to other media
such as CD-ROM. Microsoft Windows is the platform
on which SDOCS operates, with a user-friendly
interface and intuitive data display. The system
operates either standalone or on a network for
expanded access.

Special features added
early on to SDOCS include: (1) complete record management
and keyword retrieval; (2) page change management
to insert, delete, and replace pages in a document;
(3) multi-level access control to images; and (4)
complete tracking and reporting of system and document
usage. To aid the system management user, there
are a myriad of additional features, including backup
assistance, exporting text files, and scanning images
to TIFF files.
The latest improvements to SDOCS include the ability
to recover the text of the document images by OCR
(Optical Character Recognition). Complete image
management has been added for de-skewing, de-specking,
and removing horizontal and vertical lines. The
program also has the capability to scan, display
and print color photos. And since the ability to
index all the text in the document is an absolute
necessity, there is full-text retrieval capability.
The current system, which upgrades SDOCS from a
16-bit to a 32-bit operating environment, was delivered
under tasking to the Department of Energy’s
(DOE) Headquarters in Washington DC. The upgrade
enables current DOE Windows-based workstations (32-bit
processors) to utilize SDOCS software to access
the classified documents in its database. The system
is being used at several locations at DOE to manage
personnel security files and security policy documentation,
to handle classified documents in the Office of
Safeguards and Security Information Management Center,
and for documentation management in the Office of
Declassification. The system also has been installed
at over 50 other U.S. locations, including many
at Sandia National Laboratories in Albuquerque.
Other uses include timecard imaging for payroll
applications, and Contract Staff Augmentation.
In searching for a library of indexing functions
for the 32-bit version of SDOCS, Technadyne looked
for a royalty-free package that would provide clean,
fast indexing, and help with programming useful
user interfaces. Technadyne wanted the ability to
display the location of text-hits, both in the text
display window, and in the scanned document pages.
Technadyne needed to allow the user to compose Boolean-logic
text queries – without knowledge of Boolean
logic. Finally, the package Technadyne chose had
to integrate easily into a Microsoft Visual C++
application framework. Technadyne found all these
qualities in the dtSearch Text Retrieval Engine.
SDOCS uses dtSearch to index thousands of OCR text
files at a time (in a background network batch process)
or to index a single document on a user’s menu
click. The full-text searching integrates seamlessly
with the other search criteria provided by SDOCS,
allowing the user to narrow the search until the
proper documents are located and displayed.
"I particularly like the dtSearch technical
support staff," says Alfred Johnson, the Technadyne
developer who integrated the dtSearch engine into
SDOCS. "They’re much more responsive than
other software companies. Whenever I had a problem,
they supplied sample code to solve that problem.
They’re good folks to work with." |
