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.

Scientific contribution:

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.
