HiMessage: An Interactive Voice Mail System with the Humanoid Robot Pepper

Abstract

This paper presents a method aimed at providing a voice mail system encrypted by a biometric key, using the humanoid robot Pepper. Thanks to a facial recognition algorithm, Pepper is able to recognize the people who approach him. A user recognized by Pepper can record a message to be sent to another user, or can listen to messages in memory sent to him. Sensitive data, such as messages or names stored in memory, are protected by a cryptographic key on the server. In order to evaluate the presented application we selected five users between the ages of 23 and 30. Each user interacted with Pepper ten times and Pepper has been able to end the interaction as user desired in 100% of cases. It shows that the robot can work with Face Recognition and Words Recognition properly.
