“Digital preservation” is the set of process and activities that ensures long-term, sustained storage of, access to and interpretation of digital information, curation is an applied form of preservation that focuses on interpretation and is often (though not exclusively) used in relation to working with scientific datasets. The ultimate objective of all digital preservation activity, is to keep valuable and useful digital material (increasingly online) available for future generations of scholars, researchers and to the user …show more content…
Problems of physical preservation are compounded by the obsolescence of computer equipment, software, and storage media. Also refers to the practice of digitizing materials originally produced in non digital formats (print, film, etc.) to prevent permanent loss due to deterioration of the physical medium.” Digital preservation has the two dimensions i.e. preservation of materials that are born in digital form and another is digitization for preservation of printed documents and the manuscripts which are touched by the hand of deterioration. Digital preservation facilitates the global accessibility of any form of documents.
Which Types of Materials are Need for Digital Preservation
The following type of digital collections and resources are need for digital preservation:
• The print information’s are converted to digitized versions (that is reformatted information). So it is need for preservation.
• Those information are born in digital format, it is required for
This would require that a detailed description be given of the data that is the content of the computer which may have been removed from the computer and stored
FTI leverages native storage and multiple replications and erasures techniques to supply many levels of dependability and performance. FTI provides application-level check inform that enables users to pick out that knowledge must be protected, so as to enhance potency and avoid house, time and energy waste. Figure It offers an on the spot knowledge interface so users don 't have to be compelled to wear down files and/or directory names. All data is managed by FTI in a very clear fashion for the user.
Storage devices are one of the important components of any computing device. They store virtually all the information and applications on a computer, except hardware things. They are available in different form factors depending on the type of underlying device. For example, a standard computer has multiple storage devices including RAM, cache, a hard disk, an optical disk drive and externally connected USB drives. There are two different types of storage devices: • Primary Storage Devices: Generally smaller in size, are designed to hold data temporarily and are internal to the computer.
Standard 6: In military environment there are medical records of patients. Printing out the lab work or information of medications is done elsewhere, since there is not a printer close by my computer. These records are privileged papers because it is a baseline bloodwork for the program. Before handing the papers to the participant we have them tell me their full name and last four of their social security.
Also just because the digital copy of the data is deleted, this does not mean that the physical copy of the data is gone. The physical copy and the digital copy of the data are not always the same thing. For instance, the data can be altered online as long as it is done the right way. The data on the device would have to be altered using a

“The special properties and technical complexity of digital evidence often makes it even more challenging, as courts find it difficult to understand the true nature and value of that evidence (Boddington, 2015)”. It’s not uncommon for innocents to be convicted and guilty people acquitted because of digital evidence (Boddington, 2015). However, other factors can also affect the validity of the evidence, including: failure of the prosecution or a plaintiff to report exculpatory data; evidence taken out of context and misinterpreted; failure to identify relevant evidence; system and application processing errors; and so forth (Boddington, 2015). “There is a perception, largely undeserved, that digital evidence somehow alters the true nature of the original evidence and is therefore unreliable. Presented properly, digital evidence is capable of being of tremendous assistance to the courts (Hak,
With the introduction of new technology in recent years, the government can discreetly capture evidence from electronic files,
Drop box- It’s a technology that eases distribution of files. Once one puts any data in the drop box, the data or information automatically becomes available to every other member. It saves a lot of time and money. No need for items; flash disks for saving.
A simple book written with the best intentions; Ray brings to the world Fahrenheit 451 in 1953 (Kipen). Having World War II influencing Ray’s ideas for the book. Fahrenheit 451 brings ideas and points that Ray Bradbury felt the need to write and open the public’s eyes to, as to how technology is changing people’s lives and they are leaving behind books and their critical thinking. Ray Bradbury brings a book about censorship and how banning or in this case burning books does not keep people from the curiosity of the message books have. A big irony arises and his book becomes banned and censored, exactly the same way as in his book.
William Murtagh, first keeper of the National Register of Historic Places, once said “at its best, preservation engages the past in a conversation with the present over a mutual concern for the future.” Preservation has always been a part of human nature, deeply rooted in our tradition and moral code. There is a profuse amount of ways in which society preserves, some are for selfish reasons but others help us move forward and learn from our past. As the great human race, it can be said that preservation has been our main reason for being the most successful species on the planet. Sigmond Freud was an Austrian neurologist who stated that one of the “deepest essences of human nature” is that of self-preservation.

Forensic imaging, particularly MRI technology is crucial in determining the cause of death in forensic pathology. There are a few main techniques for forensic imaging, magnetic resonance imaging (MRI), post-mortem computed tomography (PMCT), and conventional radiography. The PMCT is generally used for gunshot wounds, detection of gas embolism, trauma cases, and changes in the skeletal system. Some advantages of this technique are that it is fast, easy to handle, good three-dimensional reconstruction, excellent visuals of the skeletal system and gases in the body. However, it is not without disadvantages like how it uses radiation, meaning companies must protect their employees, it has limited data storage, limited visualization of soft tissue and employees must go through extensive training to be authorized to operate it.
The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure flowchart and acquisition of digital evidence flowchart is shown on Figure 2 and Figure 3 respectively.
As far back as 2001 when the first “Digital Forensics Workshop” was held and a case for standards was made, considerable progress has been made in ensuring the growth and expansion of the practice of computer forensics. Mason (2003) suggested the need for standards by which digital forensic practitioners ensure that evidences for prosecuting cases in the law courts are valid as more judgments from a growing number of cases were reliant on the use of electronic and digital evidences in proving the cases. XXXX (2005 & 2007) emphasized the dynamic nature of technology and its impact on the digital forensics field. Hence, the need for having early standards in regulating the
