A Novel Three-Tier Multi Stage Verification System for Protection of Medical Records Over the Cloud Environment
Dr. J. Vinothkumar, Dr. S. Sutha
Abstract: This study aims to provide a multi-level authentication strategy that is secure, affordable, and easy to use. It leverages many factors to grant rights to resources on unreliable environment and facilitates money exchanges. The proposed research is predicated on the idea that an authentication scheme becomes more resilient to various sorts of assaults and harder to breach when it incorporates several tiers and multiple elements. This study aims to implement a technique known as Three Tier Multi-Stage Verification (TTMSV), which uses various factors to carry out the authentication procedure in three stages. Outside of Band (OOB) verification is another feature of the method that provides reliable defense from Man-In-The-Middle (MIM) attacks. Double encryption is used for the username and password in the first level. The second level employs Outside of Band (OOB) verification with email ID and mobile number for OTP verification. The third level involves the user interacting with a graphical interface by clicking on preset numbers of buttons and graphics and choosing preset numbers of menu items. The suggested system's security is dependent on user involvement on a graphical user interface that employs probability combinations of different integers, Outside of Band verification using OTP, and double encryption using SHA-1 and AES-128-CBC (Cipher Block Chaining).
