Applying Digital Forensics to Offline Transfer of Electronic Records
|
Brief summary:
|
The NAK
plans to transfer up to three terabytes of electronic records,
beginning in 2015. Offline transfer has been prone to various problems. The
NAK sought to overcome these by a digital forensic solution, is
currently working on standardizing that procedure, and also applied the
digital forensic transfer tools to its own case of transfer.

The Korean government began to generate electronic records in 2004
and plans to transfer up to three terabytes of these records,
beginning in 2015. Upon designing the online transfer system for these
records, the inter-system data connection level and the technical
specifications of the online transfers of these records were standardized. Applied
to the online transfer process to ensure its efficiency and the
impeccability of the records being transferred were the multi-session
transfer, multi-file transfer, time stamp token, and hash function
techniques. Offline transfer has turned out to be much more common and demanded.Other certain institutions avoided linking
their systems to the open networks for security reasons and audiovisual
records and some presidential records were too large to transmit into the
open network. The failure to predict these difficulties at the time of
designing the transfer system has left many offline-transferred
records to the risks of forgery and distortion. The NAK decided to solve
this issue by the digital forensic technology.
Digital forensics refers to a series of related techniques used to
collect, analyze, and submit digital and electronic information and is
emerging as an increasingly important instrument in investigations
and is now also surfacing as a key solution for electronic record
management. Accordingly, numerous efforts have been made in and around 2010
to incorporate digital forensics in developing the technology and
procedure. A number of international partnerships have been formed.

Research
on digital forensics continues to flourish worldwide to incorporate it into
their record management systems. The NAK has been investing sizable sums of
money to advance its record preservation techniques since 2008. This study
will further improve the understanding of the concerned people by
demonstrating its arguments about the prototype of the digitalforensic
transfer tool that has already been developed. Applications for patents
have already been filed for the digital forensic-based transfer method and
tool. Once the patents are granted, the NAK will share the system with the
private sector as well. In its discussion of the trends in digital
preservation today, this study also introduces the NAK’s
progresses on developing other techniques for the long-term storage of
electronic records.
