AUTHENTICATION HAS BECOME ONE OF THE MOST IMPORTANT FACTORS IN THE DIGITAL WORLD. SINCE WE HAVE BEGUN TO TRANSFER ALL OF OUR DATA ONTO ONLINE STORAGE DEVICES OR DIGITALIZE THE WORLD AROUND US WE CAN COMPLETE ALMOST ANY TASK ONLINE AS LONG AS WE HAVE A STABLE NETWORK CONNECTION. HOWEVER, ALTHOUGH THIS HAS HELPED US SPEED THINGS UP IN OUR LIVES IT ALSO COMES WITH THE FACT THAT DATA STORED INLINE ISN’T SECURE. DUE TO THIS REASON WE HAVE BEEN ABLE TO OBSERVE LARGE AMOUNTS OF DATA BEING STOLEN BY CRIMINAL ORGANIZATIONS AROUND THE WORLD. HOWEVER, WE HAVE BEEN ABLE TO FOLLOW VARIOUS FORMS OF ENCRYPTION METHODS TO SECURE IT BUT EVEN WITH THIS SOLUTION INTACT WE HAVE OBSERVED MANY CASES UPON WHICH A USER’S CREDENTIALS ARE STOLEN AND USED IN A NEGATIVE MANNER. TO PREVENT THIS, WE HAVE IMPLEMENTED VARIOUS METHODS SUCH AS ONE TIME PASSWORDS AND OTHER FEATURES BUT THESE AT TIMES DEEM TO BE IN EFFECTIVE. THIS IS WHY WE WOULD LIKE TO CREATE AN APP WITH THE HELP OF BLOCKCHAIN TO MAKE THE MOST SECURE AUTHENTICATION SYSTEM POSSIBLE. OUR SYSTEM WILL BE AUTHENTICATED WITH THE IMEI OF A USER’S PHONE. HAVING THE IMEI AS AN AUTHENTICATION MEANS THAT THE USER WILL NOT BE ABLE TO LOG INTO THE WEBSITE FORM ANY OTHER DEVICE EXCEPT FOR THE PHONE IN WHICH THEY HAVE REGISTERED IN.HROUGH THIS PROJECT WE WILL BE USING BLOCKCHAIN TO CREATE AN EFFECTIVE APP WITH THIS METHOD OF AUTHENTICATION
