Answer:
Explanation:
In digital image processing, degradation is a process of introducing defects to the image. Understanding the degradation function will allow restoration of the original image.
There are many different causes for image degradation such as motion blur, digital noise and lens off-focus. In cases like motion blur, it is possible to come up with an very good estimate of the actual blurring function and "undo" the blur to restore the original image. For digital noise, a statistical model can be set up to compensate for the degradation it caused. Similarly lens focus can be compensate by an optical model if the mis-focus is known.
The above are three degradations that I could find. A lot more information can be found about restoration functions. If you search for image degradation online, you will find a discussion on Quora and an interesting introduction from Rice University. Good luck!
As far as I remember, message-digest functions distill the information contained within a file (small or large) into a single fixed-length<span>number, typically between 128 and 256 bits in length. This function is designed to protect the integrity of a piece of data to define changes to any part of a message.</span>

Answer:
C. DAT-1
Explanation:
Chain of custody is applied when examining digital evidence and checking for proof that no alterations have been made to the document. It ensures that the original piece of digital evidence which could be in text, image, video, or other electronic formats, is preserved and protected from alterations. Hashing algorithms which are mathematical computations that help to condense files are applied during this procedure.
Common hashing algorithms applied, include; the message digest 4, secure hashing algorithms 1, 2, 256, 224, 512, etc. The message digest 4 is used to evaluate why a particular piece of evidence was handled by an individual. This is further authenticated by examining the fingerprint.
