Free digital content software for linux

Free Digital Money projetc is aimed at promoting ideas and stimulating further innovation in the field of digital bearer money.
Digital bearer money is like cash and can be transferred person-to-person without going through a bank or PayPal account.
Scope
The scope of this project is necessarily limited; digital bearer money schemes are difficult to implement.
The project will develop and release a Digital Money system and applications, suitable for teaching and idea-testing.
The current release (V0.2) delivers a basic digital PGP-based coin system.
The next release will provide a transport mechanism to send the coins to an intended recipient; and a client application (a Wallet).
How You Can Help
We welcome technical help in a variety of forms:
- Application writers and visionaries: to use the FreeDMoney software to experiment with new ideas
- Coders: to extend the current software or to implement a completely new payment system
- Vendors of existing digital payment schemes: to implement a FDM interface to their code
Educational Usage
Students (and others) are welcome and encouraged to use FreeDMoney as a basis for discussing other considerations of building a secure payment systems.
Examples:
- What technical peer-review process would be required to be confident in the security of the system?
- What are the limitations in the model that would need to be overcome in order to make this into a technically sound basis for a real-world, real-value payment system?
- Assuming these limitations had been overcome, what operational considerations would need to be addressed to deliver a secure, reliable payment system?
- How do existing payment systems address these issues?
What legal and regulatory issues would need to be addressed in the target jurisdictions?
Enhancements:
- Initial Coin implementation and "test bank" Web application.

X-Digital Disco System (X-DDS) is the graphical frontend for the Digital Disco System. X-Digital Disco System is based on the XMMS Multimedia Player.

About Digital Disco System:

Digital Disco System is a client/server-based audio player for disco purposes as well as at-home usage.

It has an console frontend (usable in shell scripts) and an X-fontend in the style of XMMS.

RJBs Digital Media Center is a music player.
RJBs Digital Music Center is designed to run on dedicated hardware. Because of this. It running as root. Very dangerous. Other than grabbing the X display and calling stop and halt scripts. It should be able to run as a non-root user. I will look into this on future releases.
Install steps:
(1) Install Nvidia Graphics Card.
(2) Plug X10 or IRMan control module into Com1.
(3) Connect Computer to Television
(4) Install RedHat 9.0
(5) During RedHat install select "Server Install"
(5) During package selection
(a) Select The Following Packages
X Window System
Sound and Video
Windows File Server
Development Tools
X Software Development
(b) De-Select The Following Packages
Printing Support
Text Based internet
Server Configuration Tools
Web Server
Administration Tools
(6) Identify or Create a directory for your Media files.
mkdir /usr/local/Media
Would be a good choice. The install script will ask and expect this path to exist. It will create a symbolic link to it. Also create symbolic link inside to for Cdrom to /mnt/cdrom
(7) As root UnZip/Tar the DMC release in /usr/local
cd /usr/local
tar zxvf dmc-releaseV2.0.tgz.tgz
(8) If your System is a HP DEC then you need to copy from the original HP disk the binary decvfdcmd.
cp /opt/odin/dec/bin/decvfdcmd /tmp
This binary controls the front LCD display.
The install script will ask for this path.
(9) As root run the DMC Install Script.
cd /usr/local/dmc/bin
./Install.sh
(10) Answer questions and follow instructions
(11) Good Luck!

Digital Camera Protocol is another command-line utility for DC21x cameras, this one looks and works just like "ftp" command. Not written by me, but uses some of my low-level Kodak code from digicam.

The Digital Invisible Ink Toolkit is a Java steganography tool that can hide any sort of file inside a digital image (regarding that the message will fit, and the image is 24 bit colour). Digital Invisible Ink Toolkit will work on Linux and Max OS, even on Windows because it is written in Java and thus platform independent.

There are four highly customisable algorithms in the tool, as well as an open-source implementation of RS Analysis (an extremely good steganalysis method). The tool has the additional advantage of being able to simulate hiding - so you can get an accurate map of where the information is hidden.

The compiled version can be run by simply double clicking the .jar file, or by running at a command line with the following options (you will need to run at the command line if you are using big pictures, such as those greater than 500x500 pixels or it will run out of memory):

java -jar -Xmx512m diit_1-1.jar

Where -Xmx512m tells the virtual machine to use 512MB of physical RAM (at most) - please change to suit your own machine specifications.

Digital Product Management Library SDK (DPML SDK) is a management platform for Java-based component development, resource management, and deployment.
The project is composed of the Transit resource management layer, the Depot multi-project build system, the Metro component management runtime engine, and the Station application management console.
Enhancements:
- Support was enhanced for the creation of composite components using URL resolvable parts (where a part is a building block defining a classloader chain, component, and deployment scenario).

CAM::PDF::Content is a PDF page layout parser.
SYNOPSIS
use CAM::PDF;
my $pdf = CAM::PDF->new($filename);
my $contentTree = $pdf->getPageContentTree(4);
$contentTree->validate() || die Syntax error;
print $contentTree->render(CAM::PDF::Render::Text);
$pdf->setPageContent(5, $contentTree->toString());
This class is used to manipulate the layout commands for a single page of PDF. The page content is passed as a scalar and parsed according to Adobes PDF Reference 3rd edition (for PDF v1.4). All of the commands from Appendix A of that document are parsed and understood.
Much of the content objects functionality is wrapped up in renderers that can be applied to it. See the canonical renderer, CAM::PDF::GS, and the render() method below for more details.
Enhancements:
- Perl

XML Digital Signature Tool is a Firefox extension that can process Digital Signature in XML documents (as per W3C standard for XML signature: http://www.w3.org/Signature/).

The XML digital signature tool is built on top of Apache XML security C library (version 1.3), called XSEC (http://xml.apache.org/security/c/index.html). We made no changes to XSEC source code. We just compiled the source with NSS option to provide cryptographic functionality using browsers CERT DB. The recompiled XSEC library is packaged with the XPI file for this extension.

In addition, this tool provides an XPCOM based API for wrapping C++ based Apache XML security library. Our XPCOM IDL based API allows any Firefox based extension to access XSEC library using JavaScript and C++. This tool also provides XUL based GUI for specifying various parameters for signing XML files and verifying signed XML files.

The Apache XSEC c-library uses the Apache XML projects (http://xml.apache.org/) Xerces-C XML Parser and Xalan-C XSLT processor. The latter is used for processing XPath and XSLT transforms. This tool does not include the DLL or shared library for Xercrs-C or Xalan-C. You have to download and install Apache XERCES for C (v1.3.0) and XALAN tools for C (v.1.10) before you can run this extension. The path for shared libraries or DLL of XERCES and XALAN must be in the LD_LIBRARY_PATH (for Unix) or PATH (for windows).

In addition, the tool provides following features:

- ability to generate Self-Issued SAML Token (both v1.1 and v2.0) using the RSA/DSA keys in the certificate DB. (http://docs.oasis-open.org/security/saml/v2.0/) The SAML Token generation is implemented using a XPCOM based componenet.
- XPCOM based API for UUID generation. The XPCOM implementation resues the UUID generation source code in the RFC4122 (http://www.ietf.org/rfc/rfc4122.txt). We have adpated the source code for Mozilla NSS based digest and added string based UUID API.

Note: This tool only works on Windows and Linux OSes.
