INTRODUCTION INTRODUCTION
InIn thisthis paper paper newnew methodmethod for for datadata securitysecurity
isis presented presented.. InIn thisthis methodmethod wewe areare havinghavingaa newnew ideaidea regardingregarding thethe datadata securitysecurity..
AccordingAccording toto thisthis methodmethod wewe provide provide aa
illusionillusion toto thethe unauthorizedunauthorized person person whowho
wantwant toto accessaccess thethe datadata withoutwithout our our permission permission..

For For thisthis purpose purpose ,The,The originaloriginal datadata keptkept inin oneone package package wewe willwill provide provide aa password password toto thethe originaloriginaldatadata.. andand thethe datadata whichwhich isis providing providing illusionillusion toto thetheunauthorizedunauthorized person person thatthat datadata cancan be be openopen by by anyanyother other password password exceptexcept thethe originaloriginal password password .. andand asas
anyany unauthorizedunauthorized person person willwill enter enter thethe wrongwrong password password atat leastleast for for onceonce hehe willwill getget thethe wrongwrong datadataandand thethe datadata whichwhich wewe wantedwanted toto sendsend cancan be be sendsendwithoutwithout anyany disturbancedisturbance or or modificationmodification by by anyany
unauthorizedunauthorized person person hencehence datadata cancan be be sendsend moremoreefficientlyefficiently withoutwithout anyany problem problem..

WeWe keepkeep twotwo package package of of datadata inin aa singlesingle unitunit andand oneone package package willwill containcontain thethe originaloriginal datadata whilewhile other other willwill
containcontain thethe datadata whichwhich provide provide thethe illusionillusion toto thethe
unauthorizedunauthorized person person (Hacker)(Hacker) or or misguidemisguide himhim thatthat hehe hashas

SomeSome oneone willwill trytry toto hack hack thethe datadata thenthen whatwhat wouldwould
be be thethe procedure procedure toto protect protect itit..
If If thethe authorizedauthorized person person wouldwould enter enter thethe wrongwrong
password password by by mistakemistake thenthen alsoalso itit cancan createcreate somesome
problems problems.. SuggestedSuggested implementationimplementation..

SOLUTION FOR THE PROBLEMSSOLUTION FOR THE PROBLEMS
11.. If If somesome oneone willwill trytry toto openopen our our datadata thenthen either either he/shehe/she willwill trytry toto enter enter anyany password password firstfirst andand atatleastleast for for onceonce hehe willwill definitelydefinitely enter enter thethe wrongwrong password password ..soso wrongwrong datadata packet packet willwill be be openopen.. sincesince
wewe areare openingopening thethe wrongwrong datadata packet packet by by just justenteringentering anyany wrongwrong password password other other thenthen originaloriginaloneone ..AndAnd thethe unauthorizedunauthorized person person (HACKER)(HACKER) willwillgetget thethe illusionillusion thatthat hehe hashas crackedcracked thethe datadata.. AndAndour our datadata willwill be be protected protected fromfrom anyany externalexternal
manipulationmanipulation andand disturbancedisturbance..

22.. If If thethe authorizedauthorized person person entersenters thethe wrongwrong password password by by mistakemistake hehe willwill getget aa datadata just just awayaway fromfrom hishisexpectationexpectation.. ItIt meansmeans thatthat thethe actualactual datadata whichwhich wewe arearesendingsending inin oneone packet packet (which(which isis requiredrequired data)data) andanddatadata inin other other packet packet willwill be be veryvery muchmuch differentdifferent fromfrom
thethe actualactual datadata soso thatthat thethe authorizedauthorized person person couldcouldunderstandunderstand thatthat hehe hashas enteredentered thethe wrongwrong password passwordandand couldcould correctcorrect hishis mistakemistake by by enteringentering thethe rightright password password.. ThisThis differentiationdifferentiation of of correctcorrect andand wrongwrong
datadata isis veryvery simplesimple onon thethe basis basis of of thethe fieldfield wewe areareusingusing inin thethe datadata packet packet..

CONCLUSIONCONCLUSION
AtAt present present thethe datadata securitysecurity isis thethe mainmain conceptconcept.. For For toto transmittransmit our our datadata withwith highhigh securitysecurity andand withoutwithout
anyany outer outer or or unauthorizedunauthorized manipulationmanipulation withwith fullfull of of accuracyaccuracy itit meansmeans wewe needneed toto transmittransmit thethe datadataefficientlyefficiently.. AndAnd for for thisthis efficientefficient datadata transmissiontransmission weweneedneed aa solutionsolution whichwhich cancan helphelp usus toto protect protect fromfromthisthis..
