The relevance and importance of digital images growing day by day. They are a major source of information exchange in the digital world. Digital images are used to illustrate facts, establish facts and used by the newspapers, magazines and social media to strengthen the perception. Also digital images are used as corroborative evidences in criminal investigation. So it is very much necessary to ensure the truth of what is being believed. The issue of forged images is not new, but technology advancement in hardware and software has made it easier and cheaper to manipulate an original image either to mislead the audience or to form a particular public perspective about famous personalities. Many instances (http://www.fourandsix.com/photo-tampering-history/, n.d.) have been reported in the past to justify the claim. Some of the widely circulated instances of forged images are shown in Figure 1.1. Digital image forgery may be done just for fun or for a grave illegal act. Digital image forgery may impact various aspects of society like evidence tampering, antique faking, political agenda or criminal investigation. With the menace of digital image …show more content…
The very fact about natural images that no significant regions are exactly same in an image is exploited in all such techniques. So if there is a sizable region to hint duplication then that is treated as case of copy move forgery. We have used block based methods, keypoint based methods and statistical method using independent component analysis. In the block based methods discrete cosine transform is used to convert the image information in spatial domain to frequency domain and characteristics of DCT coefficients are
but I also think evidence and such can't always be trusted. Any picture or video can be easily edited to make something appear differently. I think cell phones have actually made things worse because it allows false information to be spread incredibly fast and people don't bother to fact check or anything which causes lots of problems in our

Can an image tell us everything we want to know about what happened? Why or why not? An image can not tell us everything we want to know about what happened. The images can be changed or altered by a editor during and after a person is having an interview for example or even a picture with photoshop.

Into the Electronic Millennium by Sven Birkerts, written in 1991, is an informative essay that goes into depth about how society is becoming dependent on electronics as a way of communication. New generations will encounter drastic changes as a result of the switch from printed words to electronic media. Birkerts’ intent is to inform his audience about the dangers that electronics will bring to future generations. He thinks that seeking information through printed words are becoming a rarity for younger people. He also claims that since people are dependent on electronics now, people do not have a mind of their own.

From a common thug to a fiercely intelligent leader, Malcolm X has set the stage for an audience to be truly inspired. His passion for knowledge flows from the pages of his work, “Learning to Read,” naturally drawing the reader into a time and place many people don't know about; prison in the 1940's and '50's. Malcolms devotion to learning, albeit not in the traditional sense, shows in his writing. When describing his past, Malcolm X draws a clear picture of what his time in prison was like. Although his work is not as refined as a piece of literature from someone like Dickens or Hemingway, Malcolm X presents to his audience that willingness, motivation, and a desire to learn can go a long way. Even though Malcolm is telling
With two clicks of a button, the picture is instantly duplicated onto a new file. And there 's really no way to determine whether the image is a duplicated forgery because stolen digital art can be completely identical to the original, right down to the individual pixels. Artists can add a watermark to their work and display their name to gain recognition for their art. These watermarks can vary from small signatures in the corner, to large copyright notices stamped right in the middle of the image.
Today technology is an integral part of lives, the digitized age has incorporated itself into nearly every aspect of our culture. This even includes the methods by which we persuade defined specifically as rhetoric. I will discuss three examples of digital rhetoric, each example will be representative of a distinct form of digital media. I will then explain the manner in which the respective examples use the appeals of persuasion. I will follow up by describing how the various appeals are presented to persuade the target audience.
With recent advancements in technology, it is now far easier to fabricate fake news and make it look convincing. Image and audio editors can make photos and videos seem genuine. Websites can also be easily made to look like that of a genuine, reputable news website. As a result, most readers are unable to identify the nature of the website, causing them to believe blatant falsehoods, thereby negatively affecting their perception of certain people or organisations.
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.
Computer forensics is also commonly referred as “cyber-forensics or digital forensics” by various individuals, authors of books and also information security professionals. The goal of
