Abstract
Disclosed embodiments provide techniques for improvements in electronic communications. A mobile electronic device associated with a user measures crowd density proximate to the user. When the crowd density exceeds a threshold, a haptic signal, such as a vibration or pneumatic output, is discretely provided to the user. After issuing the haptic signal, the device listens for false data. False data is data entered by the user that is not part of the expected data sequence. The false data is used to obfuscate the true data. The randomness of the false data can be used to generate a keypair used for communication. The keypair is used for asymmetric encryption that provides an extra level of security for electronic communications from the mobile electronic device.
