      <abstract>
        <p>This article depicts a modern blockchain-based secure way to store and share information that employments elliptic bend cryptography (ECC) to form information more private and secure. As the sum of digital data grows, it gets to be increasingly critical to have solid and successful security measures. Our strategy employments both blockchain innovation and ECC to settle the issues that come with the way information is as a rule put away and shared. The blockchain is an independent record that keeps information secure and outlandish to alter. ECC, on the other hand, scrambles information unequivocally whereas utilizing less computing control than other strategies. This blend not as it were keeps information secure whereas it’s being sent and put away, but it too makes it simpler for numerous individuals to share information and control who can see it. A keen contract-based get to control instrument is built into the recommended framework. This lets clients have particular rights and consequently implements security rules. We utilize exhaustive hypothetical and viable tests to see at our system’s execution and security. This appears that it is proficient in terms of both how much it costs to run and how secure it is. The comes about appear that our strategy gets tall security with small impact on speed. This makes it a great choice for sharing secure information in numerous settings, such as for financial activities, wellbeing records, and private individual information. This work includes to the field by displaying a new way to make strides information security and protection by combining blockchain and ECC. </p>
