Improved Cipher-Text Attribute Based Sensitive Document Protection and Secure Sharing In Cloud Storage

Abstract

The existing protection technique for income tax document depends on user id and date of birth. These details are easily identified by an adversary. Hence, dual encryption technique is proposed in this work. The cipher text policy attribute based encryption is used for protection user information in an income tax document. Here, the secret key is send two different ways such as through email and mobile OTP number. Those who are having these two keys are able to access the document. When compared to existing technique, this proposed system provides better security.
