The Geo-Tagging Challenge Results

On Wednesday we had the Geo-Tagging challenge. Your mission was to analyze an image taken of a street vendor and determine where the image was taken, and more specifically what security event. The whole purpose is to demonstrate the type of information (called metadata) people can publicly share without realizing it. Here are the results.

1. This picture was taken in Mexico City. You can determine this by the Geo-Location data embedded in the image (19 26′ 13.2" N 99 8′ 27.6" W). Depending on your image viewer, it may not only show the coordinates but also the actual location. If your image viewer gives you just the coordinates, copy/paste them in Google Maps. When dealing with Geo-Location data make sure you include the N/S and E/W indicators. In this case had you left out 'N' and 'W' your location would come up as Thailand, not Mexico City.

2. If you look at the date you will see that the picture was taken on 24 November, 2011. By doing a quick search on Google, you can determine this was taken during the UNAM Security Conference.

Shouts out to @Chongelong, who was the first to figure this one out. Learn more about metadata in the upcoming April edition of OUCH!. By the way, the food was amazing, we pretty much tried everything you see on that table.

I failed this test because Windows 7's Explorer is misleading.
As I explained to Lance, and in detail via an article on my blog, Explorer doesn't show whether or not the Latitude and Longitude values are N or S, E or W. Hence I thought that both sets of coordinates were ve, which would have placed him in Thailand when taking the photo.
I am unable to provide a link to the blog, but it's easy to find.

I failed this test thanks to Explorer in Windows 7. It fails to show the full details of the metadata that you need.
Based on that experience I wrote up a ''Howto' that shows how to extract the correct coordinates and how to use them with Google Maps.
It's easy to extract Longitude and Latitude coordinates from Google Maps but not so easy to direct Google Maps using your own coordinates. Here's how:
