Secure smart home: A voiceprint and internet based authentication system for remote accessing

Smart home is now becoming prevalent with the development of the Internet of things (IOT) techniques. It is aimed at providing the user with a user-friendly method to control the home appliances such as doors, lights, even in a condition of long-distance. This controlling is generally achieved by a mobile phone which can access to the Internet. However, this can easily be breached if no security measures are taken. In this paper, we present a voiceprint and Internet based mobile authentication system, which can make authentication of smart home faster, more convenient and more secure. In addition, we proposed a dynamic threshold method to calculate a user-specific score threshold of voiceprint verification. Result shows it reduce the false rejection rate when given the equal false acceptance rate.
