Martus
From ToolCenter
Martus was developed by Benetech, "whose mission is to bring the immense power of technology to bear on social problems such as human rights, literacy, education and disability access."
The application itself involves a server and a client program, and allows basic submission and collection of human rights violation reports in plain text format, along with attached documents or images. The data structure is very simple, but the distinguishing aspect of this application is the level of security afforded to users - data transmission is encrypted to ensure the privacy of sensitive reports, and the open source nature of the software makes clear that no user data is captured.
