TrustX allows you to require that your email recipients authenticate themselves using their mobile phone/device before they can read your email or open its attachments. You can set how much security is required for a specific email – from a recipient simply selecting “Accept” on their phone all the way up to entering their PIN, taking a picture of their face (for facial image matching), and speaking a phrase (for voice matching). We may add new biometrics (including palm prints) in the future.
TrustX also provides powerful capabilities even after the email has been sent. Because protected emails are stored on separate, secure servers, you can perform a number of actions on emails even after they’ve been sent, such as enabling/disabling access, setting an expiration date or changing security levels.
