Effective Security Mechanisms for Big Data Using Block Chain Technology

Big data is referred as vast numbers of heterogeneous sources of data. The age of big data providing immense volumes of data points offers greater knowledge, such as groundbreaking research, successful management choices and greater consumer value. The details should be treated effectively in order to accomplish these objectives. The data can be in any form like structured information, unstructured information, and semi-structured records. The data can be accessed from several sources such as sensors, IOT, contact network to network, mobile to mobile communication, etc. Information security is almost as broad as big data. Information Security is pursuing essential sensitive data standards. Details relating to hospitals, client data, biometric data, financial data, confidential information, etc. can be sensitive data. Therefore, hackers can target and get confidential data quickly. If any improper access to confidential information may lead to data loss, the trust of businesses can be undermined by modification or misuse. To ensure the confidentiality of sensitive data, cryptographic methods are used. Data collection, data search and data processing should be protected by a security framework. Therefore, to deal with these systems, a new effective scheme is proposed. This study focuses on blockchain technologies to ensure critical data protection. Blockchain is a distributed database that is a collection of cryptography-generated data blocks. It contains a peer-to - peer network, distributed ledger, consensus system and infrastructure for smart contracts. The present work is proposed which involves to achieve stable data transfer & data mining of big data, a new encryption strategy blends with block chain technology. This study would lead to a specific protection framework for the transfer and retrieval of all confidential data.
