Assignment - Image Manipulation

As a forensic investigator, you will run into situations where the suspect has manipulated an image in order to obfuscate, alter, or hide information. Behind every file created on a digital device (computer, digital camera, smartphone, etc.) is data stored about the file. You can see some of this when you open File Explorer and see the date modified, size, and type of file. There is a great deal more information about each of these files that is hidden from your view. This is called ‘metadata', or data about data. With the appropriate tools, you can examine and even alter this information. This Lab exercise focuses on image file metadata and concepts commonly associated with Computer Science.

PART 1 - Image Metadata

The exchange image file format (Exif) standard defines the specification for how to store metadata and ancillary tags for multimedia files. These tags are useful in documenting information about how the content in the multimedia file was collected, stored, and modified. The list of available tags is constantly being updated, with one of the most notable updates being the Global Positioning System (GPS) coordinates being automatically applied by digital recording equipment. The ExifTool is one of several systems that are available for reading and modifying these metadata. Concepts related to digital devices can also be explored through Anatomy Of Digital Computer.

This block of instruction is for Windows versions 7 and 10.

Step 1 - Create a Microsoft Word document. Name the document "YourLastName CSC 147 Lab 9.docx" and replace ‘YourLastName' with your last name. You will be asked to document your progress through this Lab by taking screen shots of your work. Accomplish this by either using the ALT-PrtScn or CTL-PrtScn key combinations to capture the active window or the entire screen respectively. Then, while working in the Word document, use the CTL-V key combination to paste the captured screen shot into the document.

Step 2 - Download the ExifTool application from Queens University in Canada and follow the instructions exactly as provided in the assignment.

Step 3 - Start using the ExifTool for image metadata examination. Open a Command Line Interface, change your location to the Desktop, and execute ExifTool against the selected image. The analysis of metadata, file attributes, and system-generated information is closely related to Information Technology And System concepts.

PART 2 - Manipulating the Exif Data

Follow the assignment instructions to modify the File Modification Date/Time and generate the required output files. Document all steps and results exactly as required.

PART 3 - Images Downloaded from Websites

Using the same image, remove the metadata and insert a comment as instructed. Record all resulting metadata outputs and include them in the required deliverables.

PART 4 - Identifying Modified Images

Download and install GIMP, obtain baseline metadata using ExifTool, modify the image, and compare the metadata before and after manipulation. File analysis and software-generated metadata changes are commonly associated with topics in Computer System Architecture.

PART 5 - Steganography

Use the QuickStego application and the provided image to identify and extract the hidden content. Include the recovered text in the required Word document deliverable.

PART 6 - Write It Up

Manipulation of files is a key aspect of forensic examinations. Prepare a short analysis discussing these capabilities, their investigative value, and how metadata examination, image manipulation detection, and hidden-content discovery can be applied in real-world investigations.
