Abstract

Ultrasonic key recognition is a system that uses high-frequency sound as a mode of unlocking a security lock. The password is composed by the user using high-frequency sound and is then embedded in a music file that will serve as the "key". A music player will be used to play and emit this "key" and it is then being detected by a device which will serve as the "lock". The lock\´s built-in microphone will catch the sound and is then processed and analyzed by the system to compare it with the pre-composed key. Audio fingerprinting algorithm is used in processing and analysis of the sound. If a match is found, the system will allow access, otherwise if not.
