In the first video I viewed with Dr. David Brown I
found the concept of metadata a bit unclear.
I understood that this metadata can be used to trace information sent
from a computer or e-mail, but the use of the data was not clear to me. I was not sure what the purpose of some of
the data would be, or why it would be necessary to send the data. Dr. Brown said it was possible to limit the
amount of data that is sent from emails and from Microsoft Office Documents,
but I had a bit of difficulty understanding how it was done. I would be interested in making sure the data
that is sent out with some of the documents I create is limited to only things
I am comfortable with others seeing, but I did not understand how it should be
done. I have heard of metadata before,
but I never knew the extent of how it could affect those who create the data or
send it out unknowingly. In the future I
will definitely try to be more cautious about what others can view that is sent
from my computer, and limit the private information the public can see. I believe that this concept is overlooked in
the digital age we live in, and that it is not addressed as much as it probably
should be. If it truly is an issue it seems that classes which require information to be sent over the internet should address the issue up front.

The use of metadata is something like people going through your garbage to collect information about you that you didn't necessarily want people to know. He was basically saying that you should be aware and protect that information much like you would by shredding documents prior to sending them out. You could accidentally let out private or sensitive information without knowing.
ReplyDeleteThere is another, non-educational, piece of metadata that people aren't aware of and send their stuff out often without consideration which is… pictures taken with your phone. When you take pictures with your phone, the coordinates are attached to the picture and people can tell where the picture was taken. So, if someone was technologically savvy, they could tell the picture was taken in Las Vegas and not in San Francisco. Scary stuff out there with all of this technology.
Wow Dustin, I guess I never really thought about it! That makes a great deal of sense though since I will look back at pictures to try to find the dates and end up finding other data attached to the photo. This will definitely encourage me to make sure privacy settings for social media sites are secure. Thanks for the tip!
