has been turned off. Live examination technique includes collecting data on the monitor screen before shutting down the system. Chain of Custody form is an important form in the hard drive image process. The Chain of Custody refers to “documentation that identifies all changes in the control, handling, possession, ownership, or custody of a piece of evidence (Oppenheimer, 2013). It is the initial step while verifying the integrity of the evidence. The form also contains image details such as date and time, investigator name, image filename, the method used, and the hash value of the hard drive image. It is needed to testify in court to prove that the evidence’s integrity is still intact. Maintaining the Chain of Custody for being essential for the credibility of your work product and ultimate testimony. Without the Chain of Custody form, the evidence could be considered inadmissible in the court. Challenges First, hard drives have grown exponentially in size from byte to terabytes. Due to the size of the hard drives, it may take a very long for acquisition process and search through the drives for incriminating evidence. According to Computer Evidence Recovery Inc., it usually would take 4 to 5 GB of data per minute to create a forensic image. Therefore, it would take 70-80 minutes to image a 320 GB hard drive or roughly 3.5 to 4.5 hours for a 1 Terabyte hard drive. Depending on the operating systems, types, and structure of the hard drive, getting data into a state that…

A Time to Never be Forgotten I will never forget the hot Florida sun in the summertime or the squeaking of basketball shoes moving across the hardwood court. All this happened when I was in the 3rd grade. As I was eager to get out of Kansas, I started packing my bags the night before, and I usually never pack until my mom is yelling at me at the top of her lungs to get out of the door. This was going to be my second time heading back to Florida, but my first time going there for basketball. We…

Eadweard Muybridge was the first photographer to capture motion with still images, create a new medium, and invention. His first work of art capturing motion was his piece called “Cantering, Saddled” on December of 1878. Printed on collotype, a method of printing high-quality prints by using hardened gelatin without the use of a screen, on 19x24 ⅛ inch sheet, can now be viewed at the Philadelphia Museum of Art. Collotype uses heat and cold water treated dichromate-sensitized gelatin which is…

Before the camera was invented it was really difficult to record an image. You had to stand very still for a long time for the picture to be taken. If you moved just a little bit the picture would turn out blurry. In the year of 1881 George Eastman started making dry plates (Dry plates were round disks that were used instead of film). Then in 1883, George Eastman created a thin strip of paper covered in gelatin emulsion and silver balide, which is what we call film. Finally, he invented the…

remained very popular until motion toys came about and soon the concept of “persistence of vision” came forth, in which it is “the eye's capacity to retain an image even after it has been removed”. Peter Mark Roget in 1824 came up with that description and idea and helped advance in cinema. In 1831, Michael Faraday discovered the law of electromagnetic induction. He discovered the process of generating electricity and powering motors in which it contributed massively to the film industry. Soon,…

provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera.” Daniel J. Boorstin once stated (Quoteland). What is a photographer? A photographer is someone who takes pictures, typically on a camera, to record an event or capture a…

(A)-Graphics Card A graphics card is the hardware for a computer that produces the images that we see on the computer monitor. The Cards main job is to decide on how the pixels on the screen will be used to create the image then information that is creates is sent to the monitor through a cable. The graphics card has four main parts that it uses to complete the tasks. These are the motherboard where the power and data is connected through a connector, the processor this tells it how to use each…

hardware refers to machinery, which includes central processing unit, keyboard, monitor, and mouse. TB–2. Describe various methods for entering data into and interacting with a computer. Keyboards are used to breakdown linguistic input and software commands into individual units of meaning. Track pads or a mouse can be used to point, draw, simulate the behavior of other devices such as a paintbrush or airbrush, etc.… In addition, audio equipment for listening or verbal command notions, and…

In the present day, film is one of the foremost media forms in the world with nearly all cultures being represented. Film is the product of many different media forms combined into one including photography, painting, music, and sculpture just to name a few. Given that, there is art if film, but an ongoing debate questions whether film itself can be conceived as an art form at all. All films at their bare minimum are photographic images being shown in a rapid succession to give the appearance of…

they’re being lied to straight to their faces by food ads? The answer is photography. The art of capturing the perfect image has evolved from the unscripted Kodak moment to the fake, scripted Hollywood moments people see on TV every day. People can manipulate pictures at the push of a button in today’s culture so why not alter the way food is photographed too. By analyzing the way food is photographed, one can see the false misconceptions, it creates not only literally…
