I received a MMS with a picture on my phone, and I was wondering if that picture was actually taken from my contact phone or something else (like downloaded from any site and then sent by MMS).
It may seem like nothing, but due the nature of this picture, it could have some consequences for me depending on that picture being legit or not. I also have very good reasons to not trust my contact about this.
So, from some tests I did, sending a picture by MMS doesn't remove/change metadata, neither change its name, only its resolution might differ due to the compression.
Also with 3 differents phones, all added the metadata by default + some infos about the date of the picture, or a numerotation in the name.
Two things bother me with this picture and make me wonder if it's actually legit:
- the name of picture taken from any phone usually have some naming convention, being either something including the date/hour, or some numerotation. For this picture, the name is "PART_somenumber.jpg", and this number does not match in any way the date of the said photo, and is way too big for being a simple numerotation.
- there no Exif metadata at all in this picture.
I highly doubt that my contact would have removed the Exif metadata from that picture or even made any change to it in any way, but that's still a possibility.
So how likely it is that this would be the default behavior of the android smartphone of my contact for a picture actually taken with the phone?
