Horizontal is building Tella, a documentation and protection tool specifically geared for advocates, activists, and human rights defenders. Tella provides, in a unified, highly usable ecosystem, all features needed from start to end of the documentation process: collecting data, including making the data verifiable by collecting metadata about the user’s device and geolocation and using cryptographic signature to authenticate it, writing a hash of the data on the blockchain to detect future tampering attempts, hiding the data in an encrypted and hidden gallery on the user's device, to protect from device searches and physical repression backing up the gallery to a zero-access cloud to ensure the data remains accessible even if the user's device is seized or destroyed.
