Description

The Signet App is a security application for rapid and inexpensive deployment of confidential and secured communications. User can deploy the app on common Commercial Off-The-Shelf (COTS) mobile devices. The Signet App can be used for securing content with common communication methods, such as instant messaging apps or email, which cannot otherwise be considered secure.

You can exchange a contact in the Signet App over a short range Bluetooth connection when meeting your trusted contact in person. You can then secure any content in your mobile device to your listed contacts, and send the secured content over any other app that can deliver a file to your contact. Signet App itself does not have any means of communicating over the Internet.
