Chapter 3 summary Chapter three of the novel Blown to Bits speaks about the hidden secrets of the computer. The first issue chapter tackles is the issue of electronic document redaction bars. Under circumstances when government document would be released to the public crucial bits of information would be left out or blacked out using redaction bars. They could be very easily removed using the Adobe Acrobat highlighter tool These Bars could be removed and all could see the text behind it. Next the chapter discusses metadata which is a secret record of the data of any document or PDF this data contains information such as: file size, encryption, title, and many more categories. The most important data that this metadata harbors is the …show more content…
The next topic that is discussed is the topic of visual representations made by the computer such as pictures, so it speaks of how images are transferred into binary code and then reformed to create a rendering of the image. The resolution of this image is based on how many pixels the display has the more pixels the higher the resolution. The next point that of which the chapter speaks about is what happens to deleted data files. After data has been deleted the users think that it is gone. However, when data is deleted the blocks it is comprised of that are no longer part of any files are added to a “pool” of available disk blocks. This makes them accessible, if the binary code that formed the data was zeroed insead then they couldn’t be accessible. the data of the used blocks are saved to add these blocks to another file where to be reinstated into the computer in a data file. These blocks can be seen by anyone who has this knowledge, and these blocks can contain sensitive personal information that was deleted for a reason such as: account usernames, account passwords, bank account numbers, and …show more content…
after the user deletes the user believes that it is no longer available. However, it shocked me to find out that when data is deleted the blocks binary it is comprised of that are no longer part of any files are added to a “pool” of available disk blocks. The data of the used blocks are saved to add these blocks to another file where to be reinstated into the computer in a data file. This makes them available to be accessed.

as population grew, less land was available for children (this led to some people wanting t expand out west)
Emily’s act was splendid, and she never talked during her performances. Her actions were funny enough to intrigue the little children watching her perform. Oddly, the children enjoyed seeing an adult clown being outwitted by Belgan and Edward C., two dwarfed men that appeared to be the size of children. Each day, Emily worked strenuously, far exceeding the job description of a clown. Constantly mingling with the crowds, and giving continuous efforts to win laughs, Emily is a great asset to the carnival’s prosperity.
Chapter six of Blown to Bits by Hal Abelson, Ken Ledeen, and Harry Lewis focuses on the availability of bits via the internet and how easily they can be stolen. They discuss how companies attempt to combat this issue and potential issues that this can present. Throughout the chapter, the authors contemplate the effects that the internet has had on copyright infringement and legislation surrounding that. They discuss authorized use and rulings surrounding it. The overarching theme of the chapter seems to be that the internet was made to share information, however; in that process, information can be stolen easily, and that issue is not easy to combat.
The role of the Japanese in the European theater of World War II is often overlooked. They are often remembered as either the enemy in the Pacific theater or as the victims of harsh U.S. wartime policies that resulted with the widespread internment of many Japanese-American citizens. However, the Japanese also played a crucial role in the European theater, but not as our enemy. These were the men of the 442nd Regimental Combat Team, a U.S. Army unit that was made up almost entirely of soldiers of Japanese descent. The men were known as “Nisei,” which is a Japanese term that refers to children of native Japanese parents that were born in another country. While most of the Japanese population in the U.S. was interned, those who were not Japanese
Images of parts of the Beowulf manuscript are scanned in 24-bit colour, both under visible and ultraviolet light. These images may be of entire pages, or just single words or letters. The resulting image files are huge: at a maximum size of 2320 by 3072 pixels each image takes up about 20-25 MB, however they can reveal even more information than would physical examination of the original manuscripts, for example allowing the detection of alterations to the manuscripts and revealing letters that have been obscured by repairs to eighteenth century fire damage.
In the book Little Brother, written by Cory Doctorow, four teenagers Marcus, Darryl, Vanessa, more commonly known as Van, and Jose, live in San Francisco, California. These four students work to defend themselves against what they see as attacks by the government and schools on the Bill of Rights after a terrorist attack on the Oakland Bay Bridge in San Francisco, California. Little Brother portrays how surveillance has increased in San Francisco due to attacks and other illegal activities. As the story unfolds, surveillance increases in not only in San Francisco, but also throughout the entire world. Although Little Brother was published almost ten years ago, it includes 2007 surveillance technology, current day technology as well as possibilities of the future. This book shows how surveillance has increased throughout time and the many ways people devise to get around it.

The computer is considered one of the most important technological advances of the twentieth century. Security and privacy issues have been in existence long before the computer became a vital component of organizations' operations. Nevertheless, the operating features of a computer make it a double-edged sword. Computer technologies with reliable error detection and recording capabilities, permit the invasion of a supposedly secure environment to occur on a grand scale and go undetected. Furthermore, computer and communications technology permit the invasion of a persons' privacy and likewise go undetected. Two forces threaten privacy: one, the growth of information technology with its enhanced capacity for surveillance, communication, computation, storage and retrieval and two, the more insidious threat, the increased value of information in decision making. Information has become more vital in the competitive environment, thus, decision makers covet it even if it viol!
On 5 October 2009, computer equipment from a network data closet was stolen from BCBST. The items stolen were 57 unencrypted hard drives which contained over 300,000 video recording and over one million audio recordings. According to Whitman & Mattord (2010), confidentiality, integrity, and availability makes up the C.I.A triangle which is the basis of Committee on National Security model for information security, an industrial standard, (Whitman & Mattord, 2010). Confidentiality can be a synonym for encryption but also means only the people with the correct permission can access the information. One of the major security issue is the hard drives were not encrypted. The hard drives should be encrypted to prevent people from reading the information the computer. Software can be purchased which will encrypt files on hard drive with such as Folder Lock, SensiGuard, Secure IT, and more. There are open source encrypting software which are free for use which could have been used. If the hard drives were not needed, the data should hav...
There seems to be a dominant view throughout Western Civilizations that we are all living in the best possible time to be alive so far. For many of us, that tends to be the case. In Western Civilizations, literacy rates are up, child mortality is low, race relations and the LGBTQIA movements have made strides, and technology has provided a level of convenience and excess not yet seen. These simple truths that we take for granted, however, are not simple truths all across the globe. In fact, many areas have suffered due to these advances. In the play, Ruined, by Lynn Nottage, a powerful narrative is told that serves as a commentary about the destruction of local cultures due to the intrusive nature of war and Western Civilization in that it
What did they do ? Before we talk about it any further, we have to know some definitions that we use in digital forensics and digital evidence, not only two of them but the others too. This chapter will explain about it . Before we talk about it any further, we have to know the definition of what we are talking about. In the introduction we already know what digital forensic and digital evidence shortly are. In this chapter, we will more explore what they are, and some state that we found when we search about digital forensic and digital evidence. Computer forensics is a broad field and applied to the handling of crimes related to information technology. The goal of computer forensic is to securing and analyzing digital
These two famous books are still considered the main references for document examiners (Saferstein, p.5). In 1913, Osborn have had an idea of creation of an unofficial program for the interchange of concepts and research information where examiners will discuss different questions relating to the subject of field. First, Osborn invites Mr. Stein and later on, many other specialists were added to the program. These examiners learn from Mr. Osborn a large amount of information. They have learned that in order to uncover successfully all efforts, the examiners of the documents must obtain certain techniques. "Some of the techniques are to know to utilize the techniques of microscopy, photography, and even such analytical methods as chromatography. Alterations of documents through overwriting, erasures, or the more obvious crossing out of words must be recognized and characterized by the examiner as efforts intended to alter or obscure the original meaning of a document" (O'Brien & Sullivan, p.

Digital Forensic is described as “ a forensic science encompassing the recovery and investigation of materials found in digital devices “ (“Introduction to Digital Forensics,” 2011). The objective of digital forensics is to implement a well-structured investigation while preserving a documented chain of custody and evidence custody form to know what really occurred on digital devices and who was accountable for it.
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
