Photo metadata is a set of data describing and providing information about the rights and administration of an image. It allows information to be transported with an image file, in a way that can be understood by other software and human users. The pixels of image files are created by automated capture from cameras or scanners. Metadata is stored in two main places: (IPTC, 2020)
· Internally: embedded in the image file, in formats such as JPEG, DNG, PNG, TIFF
· Externally: outside the image file in a digital asset management system (DAM) or in a “sidecar” file (such as for XMP data).
Here there is one picture as a sample that we want to extract some information that is stored inside this file.
ExifTool is a platform-independent Perl library plus a command-line application for reading, writing, and editing meta information in a wide variety of files (Harvey). Now we want to extract some information from the given file (WindowsXP.jpg). The first question is:
What is this user’s avatar?
Run the below command for the WindowsXP.jpg file in the terminal.
# exiftool WindowsXP.jpg
As we see in the result Copyright = OWoodflint. Search “OWoodflint” in Google. Then one Twitter account with a cat avatar appears. So it can be the answer to the above question.
What city is this person in?
according to BSSID that shown on his Twitter post. Bssid: B4:5D:50:AA:86:41is the wireless local area network (also known as WLAN).
After that enter this Bssid=B4:5D:50:AA:86:41 in Wigle.net to find the location of this Bssid.
So the answer is London
