Does anyone know a good way to secure JPEG's?

I have some scanned images that have sensitive data, and looking for a way to transport them over the Internet (or medium) without risking 3rd party viewing and/or manipulation.

Use some encrypt software.

For instance, you can use even winrar.(although it's not the most secure encrypt)

If it's a real sensitive data, you should check KGB file compressor.

Open in new window


It uses a powerful encryption mechanism.
Just add a password while compressing a file.

Thanks - but I don't want the 2nd party (receiving) to have to have any extra software or do anything extra to open it (except maybe put in a password).
Anything along those lines?

You can still use kgb.
During the compression, you can choose to generate a SFX module wich stands for Self-Extracting.

So the file it can extract itself  without the need of any third party software.

I'm assuming you want to put the images on your web server, but you want people who try to access them to be required to put in a password.

To do this you could create a secure subfolder in your website, called (for example)

www.mysite.com/mysecureimages

Within that subfolder you can place an ".htaccess" file containing these lines. ( The path on the AuthUserFile line must be the FILE path (not the URL!) to your secure image folder. )

AuthUserFile /usr/www/www.mydomain.com/www/mysecureimages/.htpasswd
AuthGroupFile /dev/null
AuthName "Owner"
AuthType Basic

require valid-user

Open in new window


Then create an ".htpasswd" file also saved in the secure image folder.  Each line in the .htpasswd file contains a username and the (hashed) password.

Here is a link to a page that you can use to make .htpasswd file entries:

http://home.flash.net/cgi-bin/pw.pl

I made a tiny .htpasswd file for you with username "tripwire" and password "secure" so you can try it out.  Put this .htpasswd file in the secure image folder:


tripwire:7c46QBd43Si2g

Open in new window



Now, whenever a user goes to www.mydomain.com/secureimages/anyfile.jpg, they will need to enter a username and password.
