Human rights groups face increasingly sophisticated attackers with the ability to exploit their growing digital surface. When a group documenting human rights abuses against the Tibetan community came to us last year with interest in Martus, they brought with them a deep mistrust of their own hard drives. Together we decided to use an implementation method that emphasized security at all stages and selected Tails to be the default environment for their use of Martus. The Martus-on-Tails model is an exciting new venture into human rights defenders’ protection. We look forward to exploring other models and developing this one into a more mature standard.
