Abstract

Unlike XML decorated text data, SMIL constructs used for representing
multimedia documents on the web have semantics that predate XML,
because of the continuity and synchronization requirements pertaining
to continuous media that are used to convey the intended
meaning. Different syntactic representations in SMIL could provide the
same meaning at application runtimes, making use of SMIL constructs
very cumbersome in semantic web applications. To address the problem,
this talk identifies the protection object and represents it in a
normal form such that the semantics are maintained and are invariant
to syntactic variations. I will also provide runtime operational
semantics for SMIL, which do not currently exist, and a
meta-structure/metadata to model security and QoS requirements. I will
also define and introduce unbreakable SMIL constructs (an extension to
SMIL constructs) to facilitate the creation of robust and
self-describing multimedia documents, thus preventing the unintended
or malicious mixing and matching of various media components that
could lead to faulty information or wrongful incrimination due to
fabrication of evidence.


Naren Kodali received the B.S. in Computer Science from Andhra
University, India in 1997 and his M.S. in Computer Science from George
Mason University, Fairfax, VA in 2000, and the PhD degree in
Information Technology from George Mason University in
2004. Dr. Kodali's primary area of research is information security
with emphasis on security and quality of service for continuous
media. His recent research has been on surveillance architectures for
physical facilities and highway traffic. He has previously served in
various positions at Grouplogic Inc, Ecutel Inc, FreddieMac and
Navtech LLC. He is currently the Chief Technology Officer of Renko
Shnudon, Inc.
