Abstract:
Encryption, digital signature and digital watermarking are
the key techniques used in content protection and security
applications. Latest technology to prevent the digital content from
piracy and preserve the ownership information is to watermark the
digital content. Watermarking the digital content with origin
information or intended recipient identification secures content from
electronic data theft. In digital libraries enormous collection of data
is available in the form of multimedia (image, video, graphics and
audio) and needs to be abstracted to provide the end users for easy
access to the digital library. The multimedia contents are indexed by
origin, date and time of content creation, key words and titles. In this
paper, watermarking based content protection (authentication) and
digital index creation for multimedia information has been proposed.
In order to support the users for efficient use of available channel
bandwidth, high quality videos and universal supported formats,
digital libraries are supported with real time applications like video
streaming, compression, and transcoding. The compute intensive
operations of the video processing applications make a big challenge
to the existing systems, so hardware solutions for the above
problems are also presented to improve the digital video library
performance.
