An Enhanced Security Scheme for Protecting Sensitive Documents in a Public Cloud Environment Using a Dual Encryption technique

Users must be online as little as possible to use the file transfer service. Only the file's data—in identity-based encryption, the receiver's identification as a public key—is accessible to the transmitter and recipient. To receive key pairs, it is not essential to maintain track of cryptographic keys or to contact one another in advance. The Private Key Generator (PKG), which generates private key for each user's in traditional identity-based encryption, focuses on the decoding ability. As a result, the PKG necessitates complete faith in PKG, which is difficult to achieve in many circumstances. Currently, sensitive data safeguards using the user's id and birthdates'. However, this study proposes a dual encryption approach that doubles encryption. An opponent easily recognizes these facts. As a result, in a dual encryption method, we employ the Identity Based Dual Encryption Cipher (IBDEC) to protect user information in an income tax document. We use Email or a mobile OTP number to send the secret key. Only people with these two keys have access to the document. Existing methods are insecure compared to the suggested method.
