Title: Scrubbing images on Liberte
Post by: BayAreaBudz on March 20, 2012, 06:26 am
Hey guys
I am looking to become a new vendor on silk road in the next couple days and I have gotten every security measure down except for scrubbing my images.
I have transferred a couple of pics through a usb stick and put them into a folder called "pictures" on my liberte desktop.

The problem is I do not know exactly how to scrub the images of data. Do i go into the command prompt and type: exiv2 rm *pictures*

Or some other variation of that? Or do I have to download some other program?

Any info would be a great help.

I've never actually used it but, you should move into the directory pictures.  Then issue this command:

exiv2 -rm *.jpeg

I put jpeg in because that is pretty much the norm.  But, use what ever extension that the pic's are formatted in.  You can also just use the * instead of *.jpeg but, I don't like to use just the *. 

Whenever you have questions about a linux command just open up a terminal and enter the following:

man command

Where command is the name of the linux command.  For example if you want to know about the ls command just enter:

man ls

This will list detailed info about that command including all switches and their purposes.

Hope this helps.

Alright. I think I did what you told me.
I right clicked on the pictures file and went into the command prompt and entered: exiv2 -rm *.jpg.
It replied saying that no Exif data was found in the picture.

Does that mean that the pic has no data to scrub and is safe to post on these forums?

Thanks so much for the help Oldtoker. I just really want to make sure I am doing this right so I am totally secure.

Yes, that should be the case.  You can normally verify this with an Image Manipulation program such as Gimp or even an icon editor.

Is the command not exiv2 -da *.jpeg?
Then you can view the EXIF data by issuing exiv2 *.jpeg
Obviously these are all run from the folder containing the pictures.

According to the manpage -da switches adjust the date and time. -rm removes the data.

-d tgt Delete target(s) for  the  'delete'  action.  Possible
              targets are:
              a : all supported metadata (the default)
              e : Exif section
              t : Exif thumbnail only
              i : IPTC data
              x : XMP packet
              c : JPEG comment

Looks like -da does the same as -rm then!
