Secure File Sharing System Using Big Data in the Cloud

With the use of Cloud Technology, Big Data and its visualization now become an essential elements of information technology. Over the past few decades, protecting sensitive data from hackers has been a struggle. To preserve the data,numerous researchers created technologies and approaches. In this paper, new solution to create and secure data is categorized into structured, semi-structured, and unstructured forms. As all traditional technologies are only relevant to structured data. In this paper, we examined numerous security and privacy techniques that have been put out by different researchers and analyzed that using MongoDB and cloud-based securities, problems like data breaches and other security measures can be resolved. It is expensive to store data on servers and then retrieve it again, only paying customers are eligible to use it. As a result, this research will lower the cost of data retrieval and storage, that will be advantageous to regular consumers. This survey reveals that while such websites exist, they are not practical or accessible to regular consumers. Therefore, we have identified this significant flaw and are working to develop a solution. In addition to security and dependability, the system is built on secure data retrieval. The key characteristic is the necessity of a key for each user to receive data from the system, that raises security level.The main idea of this file-sharing application is to provide an online platform where documents, images, or other data can be shared without any size limitation. There are various platforms like Gmail, WhatsApp, etc where files having large sizes cannot be sent. There are no such limitations in this app user can easily upload files up to 1GB, and also they do not have to use personal drives like Google Drive, or Dropbox as the data get stored on public storage. This paper also overcomes the problem of unnecessary data gathering in the backend so that the data storing process can get optimized.
