mobile node is free and available for android phone users, especially those that yearn for privacy and security, but do not want to give up on the connectedness with friends.
with this powerful all in one app, users can chat, have their own private forum for long discussions, find dates, find taxis, manage projects/tasks, chat and share ideas with friends and strangers on the irc, and more.
authentic secure computing (asc) strongly believes that the users should be able to keep their privacy and security, while not sacrificing functionality.
this is achieved by multiple layers of cryptography, as well as not storing users’ private information serverside.
the privacy of each individual user is guaranteed since no user generated content is stored on the servers and all communications are encrypted. the local database is encrypted as well since all usergenerated content are stored only on the users’ side.
to allay the fears of those that do not yet trust the company and are fearful of tracking, a basic version without gps functionality was also launched.
the functionalities include:
1. instant messaging2. private forum3. internet relay chat (termed “shout!”)4. dating5. find taxis6. project/task management7. secure memo8. free space shredding9. dead man’s switch10. rss11. distress beacon
