Hap-Cp-Abe Based Encryption Technique With Hashed Access Policy Based Authentication Scheme For Privacy Preserving Of Phr

Abstract

As a novel abridged record of patients' medical data, PHR would be accessed online. Nevertheless, this very sensitive private information might be attained through illegal parties as of the cloud. Numerous existent algorithms utilized CP-ABE to protect the data as of unapproved users, however, it loses the high-efficiency against the conventional methods on account of the security parameters’ requirement of large size. To surmount these issues, a HAP-CP-ABE-based encryption technique with HAP based authentication scheme intended for PHR is proposed. The proposed work encompasses '3′ phases: (A) the authentication phase, which includes verification before the user uploads the PHR files. (B) Secure upload phase: initially, the features are all extracted as of the PHR files. Then, the features are lessened as of the extracted features utilizing ENT-LDA. Then, HAP will be created using SHA-512. Lastly, securely upload PHR to cloud utilizing HAP-CP-ABE. (C) In the secure download phase, primarily, the system corroborates the HAP for the requested user. If it is matched, then it permits them to access, or else the system declined permission. After authentication, the system permits the requested user to download the file. Extensive analysis along with investigational outcomes shows the proposed system's security together with efficiency.
