The general rule is that if a person can read a file then they can copy it....not much you can do about that.  Even if they can't print it, they could save the file somewhere else: floppy, usb, cd.  You would have to take away their ability to write to any folder on thier hard drive and also any external media...which is basically not a feasible thing to do.

And with e-mail....they could just e-mail it to another e-mail account and then do what they wish.

You need to deal with this issue from a policy and procedure standpoint, not a technical standpoint.

You could also look into using something like this software.. As I do not really know of any solutions that would be free or open source of this nature.



No one can argue with the statement that email is the de-facto medium for conducting business electronically. Getting product specifications, quotes, schematics, business plans, contracts, and countless other pieces of intellectual property to your clients and partners has never been easier—or more dangerous. Until recently, what recipients did with the sensitive information that you sent via email has been out of your hands. But not anymore.

Pinion SecureMail helps you safeguard intellectual assets and sensitive information that you distribute with Outlook or Lotus Notes by letting you dictate what the recipient can do with it. SecureMail relies on its unique Active Security Technology to extend file protection beyond the point at which a recipient gets secure content.

Active Security Technology empowers SecureMail to:

Monitor how recipients are using the secure content to prevent unauthorized functions.
Continuously check whether you have changed the restrictions (permissions) to ensure that they are passed on to the recipient.
In short, SecureMail gives you continuous and complete control over information that you have distributed via email through its entire lifecycle. We call this Secure Information Sharing.

I see the problem like  luv2smile pointed out: The more you prohibit use, the more likely someone tries to copy the content.
I once recieved an Email with an accesscode in lotus notes. Copying and printing and even forwarding was disabled.  Well not disabled was makeing a screencopy. So I did this. (Was no security breach, don't worry)

A simple pen is the worst copyprotection breach you can imagine.

A hires digicam might be a problem too.

just my 2 cents,
Tolomir

But keep in mind no matter what you do there is always ways around....

For the above suggestions a simple bootdisk with a linux distro and a couple of algorythms and your ready to start copying.  The only thing you can hope to do is to "keep the honest, honest".

Alright, there is this new microsoft, for your eyes only security scheme.

http://www.microsoft.com/windowsserver2003/techinfo/overview/rm.mspx

This paper provides an overview of Microsoft Windows Rights Management Services (RMS) with Service Pack 1 for Windows Server 2003. RMS is information protection technology that works with RMS-enabled applications to help safeguard digital information from unauthorized use—both online and offline, inside and outside of the firewall.

The dramatic rise in cyber crime and the emergence of related new legislative requirements point to the need for better means to protect digital information. While organizations such as financial institutions, government agencies, healthcare organizations, and professional services firms address many security concerns adequately, their strategies usually focus on access and delivery of information. To augment perimeter-based (firewalls, repositories) or transport-based (encrypted delivery) security technologies, organizations also need to better protect information after it has been accessed by or delivered to an authorized individual, helping to prevent sensitive information from intentionally or accidentally getting into the wrong hands.

Included in This Document
•      Safeguarding Digital Information in an Increasingly Connected World
•      Why Current Solutions Cannot Address This Growing Problem
•      Introducing RMS in the Windows Platform
•      Windows RMS Components
•      RMS Workflow
•      The Benefits of RMS
•      Flexible and Customizable Technology
•      Maintaining Existing Investments
•      Summary
•      Appendix: The Emerging Standard for RMS Interoperability

What Is RMS?

Microsoft Windows Rights Management Services (RMS) for Windows Server 2003 is information protection technology that works with RMS-enabled applications to help safeguard digital information from unauthorized use—both online and offline, inside and outside of the firewall. RMS augments an organization's security strategy by providing protection of information through persistent usage policies, which remain with the information—no matter where it goes.

Microsoft has heard from customers that they need new ways to safeguard sensitive information such as customer data, financial reports, product specifications, and confidential e-mail messages, and new ways to prevent this information from intentionally or accidentally getting into the wrong hands. RMS is the response to that need.

RMS combines Windows Server 2003 features, developer tools, and proven security technologies—including encryption, certificates, and authentication—to help create reliable information protection solutions. In addition, powerful solutions created by Microsoft technology partners extend the capabilities of RMS for specific business requirements.

My thoughts...

1. Protection of documents in email. Once an email has vacated a controlled environment it has no protection, even transmission thru the net is pretty much public domain. Using PGP encryption and signing will prevent users intercepting the mail and decoding the contents.

2. Decoded attachments. Once an email (or any other encrypted file) has been decrypted and saved it is back to a document. You could use PDF format to add password protection, print denial and edit denial to the document. If this is not enough I have heard you can embed PGP keys into a PDF document for encryption purposes, but have no details on this.

3. Screen printing. This is not controllable from any outside environment as it is the domain of the local machine. The best way seems to be a password protected PDF which will prevent the 'thief' from opening the document in the first place to be able to perform a screen dump.

Hope this helps a little...

Another thought,

Regarding your 'Hard Copy' addition. I have seen people use pale blue text (with no black content) which will not reproduce on photocopiers. Although this can be defeated with coloured lamps or filters applied to the copier. There are also certain colours used in banknotes which cannot be duplicated on colour copiers either, this is just a variation on the 'pale blue ink' concept.

Sorry to keep adding stuff.
Just had a look at the Acrobat site from Adobe, and digital signatures are now a standard function of the Acrobat product range. Have a look at this link for more info.

[SafeGuard® PrivateCrypto]
Effective security on mobile devices, PCs and for E-Mails

As anyone responsible for data security already knows, most company data is either not stored securely or is emailed as plain text. Campaigns to secure internal and external communications by using Public Key infrastructures (PKIs) have so far failed to provide a comprehensive solution.

SafeGuard PrivateCrypto can close these security loopholes. It provides encryption that is both easy to integrate and to use. It can protect valuable, confidential data on PDAs, Notebooks and PCs and ensure that it is sent securely by email.

SafeGuard PrivateCrypto integrates seamlessly in Microsoft Windows Explorer and standard email applications such as Lotus Notes and Microsoft Outlook. No need for expensive upgrades to the existing IT infrastructure! SafeGuard PrivateCrypto’s easily-understood functionality means users do not need any additional training. Users can encrypt and save the files they want simply by clicking their right-hand mouse button to activate SafeGuard PrivateCrypto in the context menu.

SafeGuard PrivateCrypto offers maximum flexibility in today’s complex IT environments. It can be implemented on all standard mobile device platforms, saving files securely on PDAs, Notebooks and desktop PCs. In addition, users can easily exchange encrypted data by email without the recipient having SafeGuard PrivateCrypto installed on his device. Because the files are self-extracting the recipient does not need special software. All the communication partners require for the secure email traffic is the password which they use to encrypt or decrypt the file.

SafeGuard PrivateCrypto has two other exclusive functions that make it even more user-friendly and ensure data remains confidential: an easy-to-use password logging provides a handy way to solve the problem of forgotten passwords, and the “secure wipe” function guarantees that original files are removed completely from the storage medium.
