With the growing trend of cloud computing, the necessity for secure data storage arises as traditional security measures fail with different types of new emerging cyber threats. The paper introduces a file storage system that maintains secure data confidentiality and integrity in the cloud environment using Blowfish encryption. File upload will now allow a user to encrypt and store files for decryption purposes only by authorized users with their encryption keys. Key functionalities will include strong authentication of users, file encryption, and key management according to secure management-all housed within a cloud infrastructure-AWS. This also serves to aid in multiple host systems access, hence scalable and reliable.
