Current through September 24, 2024
The comprehensive management of a document imaging system is
key to its functional success as well as the quality, integrity, and
authenticity of the imaged records. System planning, design, budgeting,
procurement, procedure formulation, training, and testing all require
thoughtful deliberation and patience.
The following is an overview of required practices in several
categories of system management and operation.
A.
Documentation:
Comprehensive procedural and system documentation must be
maintained to ensure that the operation continues to function effectively over
time. The documentation shall include:
1. Hardware and software specifications,
brand names, versions, and dates of installation, upgrade, replacement, and
conversion.
2. An overview of
system purposes and uses.
3.
Policies and procedures for all aspects of system operation and maintenance,
including procurement, file and document preparation for scanning, data entry,
quality control, indexing, corrections, expungement, redaction, back-ups,
security, migration, application of safeguards to prevent tampering and
unauthorized access, and printing.
4. Data structure and content, including file
layout and data dictionaries.
5.
Enhancement algorithms are techniques for processing the image so that the
result is visually clearer than the original image. Imaging systems should not
be capable of altering a record as scanned, except for standard
computer-enhancement routines used to improve legibility.
6. Documentation is also necessary for
providing audit trails, for establishing legal admissibility of images, and for
use by future system operators as staffs change. It is the responsibility of
the systems administrators, not the vendor.
B.
Quality Control:
1. To ensure the integrity and legibility of
scanned images, there must be in place established procedures for quality
control. Visual quality inspection of each image is necessary and should be
performed initially by the staff member scanning and then by a second staff
member.
2. The accuracy of the
index must also be verified through visual inspection by a second staff member
of each index entry following either entry of terms or creation through optical
or intelligent character recognition.
3. The system should also include the ability
to rescan and to correct indexing errors before the image and/or index is
written to optical media.
4.
Quality control issues must be raised with vendors during the selection process
and be considered when planning for time and staff budgeting. Since original
records are more often than not destroyed once reformatted, the importance of
image and index quality control must not be underestimated.
5. Information regarding the establishment
and use of procedures for the ongoing control of quality within an electronic
imaging system may be found in ANSI/AIIM MS44-1988 (R1993), Recommended
Practice for Quality Control of Image Scanners.
6. Information regarding appropriate use of
test charts and patterns in document imaging applications may be found in AIIM
TR38-1996, Compilation of Test Targets for Document Imaging Systems.
C.
Indexing:
1. Complete, appropriate and accurate
indexing capability is essential. Indexing and information retrieval needs must
be assessed during system planning and design. Migration and long-term
usability planning must also include consideration of continuing information
retrieval requirements. As noted in F.7, information on establishing index
fields in an electronic imaging system may be found in ANSI/AIIM TR40-1995,
Suggested Index Fields for Documents in Electronic Image
Environments.
2. The importance of
indexing requires that vendor claims be validated through demonstration and
testing.
D.
Migration:
1. A comprehensive plan for
refreshing data and for migrating images, indexes and related data through
successive versions of hardware and software is essential for ensuring
long-term access to imaged records. Not only should plans be established for
the migration of images and related data, but structural data relationships
should be preserved under migration. The strategy should facilitate the
movement of records from one generation of technology to another and should
take into consideration vendor stability and dependability, system
obsolescence, and media longevity.
2. The reality of obsolescence requires that
agencies and governmental entities keep pace with constant developments and
improvements. Technology trends must be monitored. The technology choices made
when systems are developed or upgraded may determine the ease of
migration.
3. Systems should
consist of hardware and software that conform to non-proprietary standards and
should be constructed in an open system architecture.
4. Budgeting and planning should include
consideration of the costs of technology upgrades and data migration.
E.
Back-up, Disaster
Recovery, and Security Copies:
1.
Back-up procedures and disaster recovery plans should be in place with
specified provisions for the imaging system. Detailed information on back-ups
and disaster recovery should be obtained from vendors. Back-up expense and
complexity can vary depending on the type of media and the amount of data to be
stored and must be considered during the planning and selection
process.
2. A regular schedule of
back-ups should be instituted for all data on the system, including
indexes.
3. Security copies should
be labeled with information to include date, system, and software used, and any
existing restrictions on access, keeping in mind that it is impossible to
determine content merely by looking at a disk or tape. It is preferable that
security copies be stored off site, in an area with stable environmental
conditions and with adherence to the manufacturers specifications for the
storage of the media, whether magnetic or optical. Information regarding
optical media storage may be found in ANSI/PIMA IT9.25-1998, Imaging
Materials-Optical Disc Media-Storage.
F.
Expungement/Redaction/Encryption
Capabilities:
1. Agencies and
governmental entities should have in place a strategy to guarantee that
material exempted from disclosure is not made available to the public. Imaging
systems should have the capability to expunge images and index entries and to
redact confidential portions of images or indexes when required by law. System
administrators may also wish to further insure privacy of their data through
the use of an encryption technique by which data is scrambled before
transmission and then unscrambled (decrypted) by the receiver.
2. The potential need for expungement,
redaction and encryption capabilities must be assessed on the front end and
discussed with vendors when planning for long-term usability of an imaging
system. Explanation of procedures for expunging information on WORM optical
systems may be found in ANSI/AIIM TR28-1991, The Expungement of Information
Recorded On Optical Write-Once-Read-Many (WORM) Systems.
G.
Legality:
1. The legal admissibility of reproductions
of state and county records is addressed by Mississippi Code Annotated (MCA)
Sections
25-59-29
and
19-15-3,
respectively.
2. Requirements for
the legal acceptance of records are outlined in ANSI/AIIMs TR-31 (1992-1994), a
four-part legal admissibility series, and the Mississippi Rules of
Evidence.
H.
System Selection:
1.
Agencies/governmental entities should conduct a thorough survey of document and
paper types, sizes, colors, and contrasts within their records and collect
examples of potential problems or obstacles, such as browned and fragile
papers, pencil and pen handwriting, bound volumes, photographs, and oversized
items. Before selection, a scanner should demonstrate the ability to handle the
job. The potential need for flatbed scanning capability rather than automatic
feed alone must also be assessed, both for immediate and future
needs.
2. The selection of a vendor
is perhaps the most important single decision impacting an imaging systems
success. A vendors stability, accessibility, and long-term viability must be
assessed when procuring a system heavily dependent on vendor support.
