Abstract: Disclosed are authentication systems and techniques that can automatically recognize, validate, and utilize different types of information including user information, device information, and network information. Each of these types of information is processed with a unique algorithm and then is encrypted for security purposes. The processed and encrypted information are then used as components of a multi-factor authentication process. During an actual authentication transaction, these unique identifiers are used along with real-time personal identification methods including, but not limited to, biometrics and/or a personal identification number (the “PIN”), to complete the authentication process between two devices. A backend server communicates to both the devices to create a highly secure closed-loop authentication process.
