Hiding - protecting a file
 

I have a usb key that I carry with me along with my home keys. Ι have some files on it that I like to keep them hidden/protected should I ever loose the USB key. Some time back there was a thread about the issue but I can find it.

What would you recommend - besides not loosing the key ring.


Many thanks for sharing your wisdom.

I would put them onto a 'cloud' storage site such as Dropbox. USB keys are susceptible to damage, as well as loss.

I learnt this the hard way ....... I put some presentations onto a USB key, travelled 6000 miles to give the presentations, and the files had somehow become corrupted.

Plenty of freeware encryption utilities - but then you need to work out how you will decrpyt the files.............................:)

TrueCrypt is a nice app, you can make it portable to include it in the USB and encrypt the unit... visit their web so you can think if it suits your needs.

- refer post #1?

Simply find a utility that creates self-extracting encrypted archives.

Job done.

And cloud storage isn't ? :ugh:

Cloud storage is nothing but a bunch of servers in a datacentre, infact, its worse than that, because they generally use cutting edge unproven software architecture to spread the files around.

Everything is susceptible to data loss Mr Captonian, everything.... that's why I keep banging on that you should have a minimum of three independent copies of your data at any one time.

Agreed, but I suspect that an application such as Dropbox is more robust than a USB key. Better of course would be to store on both.

use Truecrypt
not only can you encrypt the files, you can hide them from view , or hide the partition they are on
You can also now buy relatively cheaply pen drives which come with their own hardware encryption, but that won't actually hide the files.
what you use depends on what you want it for. If you need to avoid detection of your posession of the files, then you need Truecrypt. By using that, the existence of the files is totally deniable

Run your own server is an option too...

I have used usb keys to store folders of files containing only text files thinking they were a huge step forward from having to burn compact discs. But one by one when I have tried to access those files to update them, I receive an error "this disc is unusable". I had multiple backups but it got really messy trying to maintain all of them. Now, I back up onto an external HDD and when necessary go to it for extraction. I have found 4-8 gig usb keys are handy if you don't put too much on them.

you can't put your own server into a pocket. Nor can you always log into it remotely from overseas...
The theory is good, but the reality is that the internet is'nt always that instantly available yet

As well as encrypting the files, you could also add a selection of apps from the PortableApps range and take your working environment with you.

As others have said, Truecrypt works very well and is cross-platform (with a bit of farting around)

Apparently some people are buying low-capacity drives then sticking programs on them to make them seem larger.

They act as if data is being stored but you can't recover it.

I use this program to check any usb drive I get -

Have you tried the simple right click on the file, go to properties and tick the hide option.

Of course, you wont be able to see it there either. :eek:

simply hiding the file is not secure

True , it doesnt secure the file. but the orginal quetion was , so in essence hiding does protect against casual intrusion.. I also took the slash (/) as an or making the question hide or protect.

Thanks for all the help so far. Regarding Avtrician's points yes he/she is right. I think I should go for the protecting part as I want to keep the files unaccessible to everyone who might find my USB.

As usual the help is really helpfull:ok:
