Improved Data Security Using Video Steganography with Time Limited Password Nyo, Hnin Lai Hlaing, Aye Su In the era of fast information interchange, videoSteganography and data hiding techniques havebecome essential tool for information security andsecret communications. Steganography is the scienceof embedding secret information into the cover mediawith the modification to the cover image, whichcannot be easily identified by human eyes.Hidingsecret information in video file is known as videosteganography. Because of security threats todaythrough modern malevolent technology, confidentialinformation is at risk such as medical records andbanking or financial data.This proposal aims toimprove security, robustness and payload capacityusing video file. Thus, to embed the secret imagebehind the video file transformation technique(discrete wavelt transform and arnold transform), toperform double key encryption steps, twist exchangeprocess will be used. Moreover, to extract encryptedkey behind the audio file random password with timelimitation system is also used for more authenticatedsystem. 2017-02-16 http://hdl.handle.net/20.500.12678/0000004901 https://meral.edu.mm/records/4901
