The objective of this fall 2008 ELEC 301 class project is to hide a binary message within a piece of audio without damaging perceptual sound quality. This Module is an abstract summary of the work done to meet that objective.
This Module details the conclusions reached about three different encoding and decoding algorithms used to hide digital data in audio for the fall 2008 ELEC 301 class project. For small amounts of noise, all three algorithms work effectively to encode binary data in many types of music.
This Module details the ideas that could be used to extend or improve the fall 2008 ELEC 301 class project on information hiding and audio watermarking.
This module details the "attacks" used to test the three methods of encryption (frequency, phase, and echo) and how they responded to deliberate external attempts to break them. This is a continuation of the fall 2008 ELEC 301 class project.
This module details the testing methods used to compare the three methods of encryption (frequency, phase, and echo) studied as part of the fall 2008 ELEC 301 class project.
