Snowden has developed an Android app that can block espionage

Edward Snowden, a former Defense Department employee, became famous for disclosing U.S.-British surveillance programs (Prism Doors), which some see as "security fighters" on the Internet.

Snowden's recent move is about smartphones, and he and the team (the News Foundation, the Guardian Project) are involved in making  Android app development and have been on the Play Store called Haven.

Haven's current function is designed to call camera, microphone and other mobile phone sensors, the host environment to identify induction.
Officials say you can install Haven on a backup machine, and then when you're away from home or a hotel, the backup machine monitors if anyone has stolen it by light, sound, and more of app development.

These videos, photos and other "evidence" can also be set to send real-time mainframe, almost equivalent to a "watchdog."
Of course, Haven can also be installed on the mainframe, which has built-in encryption application Signal, and can be used with Orbot's darknet server to ensure that all data is encrypted locally.

Earlier, Snowden had also shared their own views on cell phone / laptop security, such as the proposal to only use the headset to answer the phone, blocking the laptop front camera.
