Abstract
Cloud computing is becoming a major player in the information technology business as of its increased effectiveness, broad accessibility, low cost, and numerous advantages. It similarly offers additional storage capacity for Internet users and faster data transmission from one locality to another. Because of the large amount of storage available, cloud users can save a significant amount of money on IT infrastructure while focusing on their central business. As a result, a growing number of businesses and organizations are migrating to the cloud. However, due to security and privacy issues, many customers are hesitant to use the cloud. In a cloud computing system, all data is distributed across a network of remote servers and locations. Unauthorized cloud users gained access to this information via virtual computers. To address this issue, this paper proposes efficient secure data storage and retrieval system for cloud environment. To offer an additional level for cloud data security, this paper proposes authentication through encryption consuming public key cryptography, as well as multiple authentication-based data retrieval. The proposed Authentication Based Encryption approach contributes to better data security and cloud user authentication. The profound data is encrypted first and at that time secretly saved with the user's biometric finger print image. The resulting image is then transferred via an insecure channel. To prevent unauthorized access, the image is deconstructed and saved in the cloud distinctly as an encrypted message and a fingerprint. To improve system security, the encrypted and decrypted key value is appropriately selected using a search method. Following the encryption process, a data recovery procedure based on multiple security authentications is initiated. Unauthorized individuals will not be able to assault the data as a result of this. The proposed methodology's performance is executed, and the results are examined using several measures.
