Methods and systems of authenticating of personal communications

A system for authenticating an individual's location activity, comprising:

• a mobile communications device connected to a network and in electronic communication with authentication protocol software stored on a server connected to the network;
• using the authentication protocol software to send a communication to the mobile device, the communication comprising a message configured to elicit a response comprising a same message back from the mobile device;
• the mobile communications device comprising a processor, memory connected to the processor, and additional software stored in the memory configured to:
• receive the communication from the server and receive the same message entered into the mobile device by the individual;
• receive biometric data entered by the individual as an input into the mobile communications device;
• access location information for the mobile communications device using a GPS application stored on the mobile communications device;
• access time information for the mobile communications device from a clock application stored on the mobile communications device;
• periodically record sounds from an environment around the mobile communications device, wherein the sounds are not biometric data entered by the individual;
• storing on the mobile communications device an encrypted digital certificate comprising a hash calculation using the response, the sounds, the biometric data, a validation key, the location information, and the time information;
• transmitting the digital certificate to the authentication protocol software and verify the encrypted digital certificate at the server with the validation key.
