Have you ever wondered if there was a hidden message in the song you were dancing to? Well, there very well might be. A Polish man named Krysztof Szczypiorski from the Warsaw University of Technology has created a new form of cryptography. He has created an algorithm that can encode and decode secret messages in dance music. These messages are virtually undetectable by the human ear. Szczypiorski has named his program "StegIbiza." "Steg" stands for steganography, which is basically hiding hidden messages in plain sight. Audio steganography is not a new concept; throughout history notes have been used to spell out hidden messages in different ways. However, Szczypiorski's form of steganography is unique.
Szczypiorski uses variation in tempo embedded in various club dance style songs to encrypt his messages. The tempo changes are so subtle that professional musicians, when asked to listen for the message, could only detect the changes when the tempo was altered by two and three percents. The tempo changes act as a "digital morse code;" when the tempo is sped up, it represents a dot, while slowing down the tempo represents a dash. Szczypiorski's algorithm can detect the changes in tempo, decoding the message.
While this algorithm may not be revolutionary or change any lives, it is a pretty cool way to send hidden messages through music.
