Cloud Data Security Using Filters Authentication and Encryption

The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is present at remote location. Cloud can provide services over network, i.e., on public networks or on private networks, i.e., WAN, LAN or VPN. Applications such as e-mail, web conferencing, customer relationship management (CRM), all run in cloud. Cloud is a technology invention. It provides the computational resources (Server, Storage, OS and Network) to user as service based on demand. Cloud computing has emerged as a popular solution to provide cheap and easy access to externalized Information Technology resources. An increasing number of organizations benefit from Cloud computing to host their applications [1]-[2]. Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure and application.Cloud computing eliminates the need of having a complete infrastructure of hardware and software to meet users requirements and applications. It can be thought of or considered as a complete or a partial outsourcing of hardware and software resources. To access cloud applications, a good Internet connection and a standard Internet browser are required. The National Institute of Standard and Technology defines cloud computing in the following way: Cloud Computing is a model for enabling convenient, on demand network access to share pool of configurable computing resources e.g. networks, services, storage, applications that can be rapidly provisioned and released with minimal management effort or service provider interaction [6].Many vendors declared that adoption of this technology can bring many benefits to the users such as cost reduction, convenience and continuous availability, scalability and performance, quick deployment and ease of integration, yet some organization are still not feeling comfortable in adoption of this technology due to concerns of trust and security e.g., data security is one of them [7, 8]. One of the best ways to ensure confidentiality of secret data in the cloud is to utilize encryption for data. Almost all cloud service providers support encryption for data storage [10]. To protect user‘s secret data in the cloud, encryption is considered as essential tool that can be used efficiently. User can confidently utilize cloud services by knowing that their confidential data is protected by encryption.In cloud computing, Security of file or data is provided to the end user in the private cloud environment. The main concern is to provide the security to end user to protect files or data from unauthorized user. Difference is that the research is done in cloud, but security related issue can’t be resolved completely. Security is the main intention of any technology through which unauthorized users can't access your file or data in cloud. In this research work we are going to resolve cloud data security issues through Filter Authentication and Encription.In particularly, we intend to discuss cloud security requirement and data privacy issues. In this research work we are proposing three layers of security architecture using Filters as First Layer Authentication as second Layer and encryption as third Layer to provide complete data security in the cloud.
