(cid:129) A bridge between new research results, as published in journal articles, and a
contextualliteraturereview
(cid:129) Asnapshotofahotoremergingtopic
(cid:129) Anin-depthcasestudyorclinicalexample
(cid:129) A presentation of core concepts that students must understand in order to make
independentcontributions
Briefs are characterized by fast, global electronic dissemination, standard pub-
lishing contracts, standardized manuscript preparation and formatting guidelines,
andexpeditedproductionschedules.
The goal of theSpringerBriefs in Speech Technology series is to serve as an
importantreferenceguideforspeechdevelopers,systemdesigners,speechengineers

Preface
Today,theuseofdigitaldatalikeimage,audio,andvideoistremendouslyincreas-
ing due to the advancement in technology and the Internet revolution. With these
advancements, attaining one’s ownership and copyrights for this digital data is the
biggest challenge. Digital watermarking is one of the technique to attain one’s
ownership and copyrights securely. It is the technique in which the owner’s copy-
rightinformationcanbeembeddedintotheoriginalmediaintheformofanimage,
audio,text,orvideo.Therearetwomainfactorsweneedtoobservefordigitalaudio
watermarkingtomaintaintherobustnessaswell asimperceptibility againstpiracy,
malicious attacks, and various transformation operations. Though there are many
challenges to achieve these results, there are two approaches presented for audio
watermarking that are used to improve the robustness, and imperceptibility of the
embeddedinformationwithsecurity.Toprovidethesecurity,DSSSEncryptionand
Decryption algorithm is used which is based on synchronized secret key concept
