Certain investigations on efficient Robust watermarking algorithms for Enhancement of security in images

Abstract

Owing to the development of latest technologies in the areas of newlinecommunication and computer networks present day businesses are moving to newlinethe digital world for effectiveness, convenience and security There are a newlinenumber of applications in healthcare industry like tele consulting tele surgery newlineand tele diagnosis All these applications require the exchange of medical newlineimages in digital format from one geographical location to another throughout newlinethe globe via a cheap and fast network such as the Internet However the newlinedigital form of a medical image can easily be manipulated through image newlineprocessing software For instance insurance companies hospitals as well as newlinepatients might want to modify the medical images for a number of reasons newlineThe tampered images may be used for illegal purposes Today s healthcare newlineinvolves some security risks as these provide new ways to store access and newlinedistribute medical data Watermarking can be seen as an additional tool for newlinesecurity measures newlineThe objective of this research is to investigate how to use Digital newlineWatermarking principles to protect a medical image detect tampering of newlineimages and recover the original one Watermarking technology is categorized newlineas robust fragile and semi fragile watermarking each serving its own newlinepurposes In order to facilitate sharing and remote handling of medical newlineimages robust watermarking technique will solve the problem of copyright newlineprotection newline newline
