I realize that the generic answer to this will be "It is stored or cached temporarily locally be Chrome", but I could not find a detailed specific set of answers. My questions follow below, but a tiny bit of background first.
My question is security driven. For example, if I happen to look at 2 years of my bank statements (PDF's) while on my banking site, I want to make sure that those are not easily accessible if my laptop was stolen by somehow simply scrutinizing Chrome temp files.
Any pointers to a complete description of how this works (specific to PDF viewing) would be great, but here is what I am trying to understand.
#1 - Where is the content of the PDF stored when Chrome is your viewer.?
#2 - When, exactly is this content removed if I take no special action to do so?
#3 - If it's a temporary file, what is the naming convention used and is a separate file created for each PDF you view?
#4 - If it's a temporary file, does Chrome store it is some proprietary format or can you just open the temp file with another PDF viewer?
#5 - If it's in a cache, will the timestamp of the cache file get updated as soon as the PDF contents is viewed?
#6 - If it's in a cache, does Chrome store it is some proprietary format or do cache viewers exist to easily find the PDF content inside the cache?
I might have some followup questions, but that I think is the core of them for now.
