Enhancing Cloud Data Privacy Using Pre-Internet Data Encryption

Abstract

Cloud computing is one of the greatest and authoritative paradigms in computing as it provides access and use of various third-party services at a lower cost. However, there exist various security challenges facing cloud computing especially in the aspect of data privacy and this is more critical when dealing with sensitive personal or organization's data. Cloud service providers encrypt data during transfer from the local hard drive to the cloud server and at the server-side, the only problem is that the encryption key is stored by the service provider meaning they can decrypt your data. This paper discusses how cloud security can be enhanced by using client-side data encryption (pre-internet encryption), this will allow the clients to encrypt data before uploading to the cloud and store the key themselves. This means that data will be rendered to the cloud in an unreadable and secure format that cannot be accessed by unauthorized persons.
