Abstract:
In the era of fast information interchange, video
Steganography and data hiding techniques have
become essential tool for information security and
secret communications. Steganography is the science
of embedding secret information into the cover media
with the modification to the cover image, which
cannot be easily identified by human eyes.Hiding
secret information in video file is known as video
steganography. Because of security threats today
through modern malevolent technology, confidential
information is at risk such as medical records and
banking or financial data.This proposal aims to
improve security, robustness and payload capacity
using video file. Thus, to embed the secret image
behind the video file transformation technique
(discrete wavelt transform and arnold transform), to
perform double key encryption steps, twist exchange
process will be used. Moreover, to extract encrypted
key behind the audio file random password with time
limitation system is also used for more authenticated
system.
