Privacy Preserving Q-Pragmatic-Sensitive Feature Analysis based Blockchain Security Using Provable Partition Fold Padding Encryption

Information security is important factor in decentralized cloud environment because of sharing personalized information among the Internet need privacy preserving to protect the data. In recent days, the Blockchain security is a developing technique to protect the healthcare sensitive information in outsourced cloud environment. But increasing malicious activity and cryptography ley leakages leads security failures. Most security considering the privacy information as common to protect information publicly. This creates a chance of sensitive information attacks to attain the data. To resolve this security problem, we propose a privacy preserving Q-Pragmatic-Sensitive Feature Analysis (PP-QPSFA) based Blockchain security using provable partition fold padding encryption (PP-FPE) to improve the healthcare transaction security. Initially the Term Frequency Behavior Analysis (TFBA) estimate the privacy concerns of user accessibility. The Q-pragmatic-sensitive feature analysis (PP-QPSFA) is attained to find the sensitive privacy feature terms. Then to make secure data using Provable Partition Fold Padding Encryption (PP-FPE) and verified through Role Based Access Verification (RBA V) to make authentication. The proposed system proves higher security concern in blockchain healthcare to improve the privacy preserving in cloud environment.
