The Security of data is becoming a fundamental obstruction in cloud computing .There are a numbers of solutions that provide some security with model, some technology. In this paper we attempt to secure data from unauthorized access, by using RSA algorithm.For providing data security by encrypting the given data based on the KEY combinations. This data then can only be decrypted by some authorized person by using his private key. The Google application cloud has been implemented on IJCT Foundation, all data has of IJCT Foundation shifted to Google cloud and RSA security algorithm is implemented by for security data.


INTRODUCTION
In past three decades, the world of computation has been distorted from centralized to distributed systems and now we are getting back to the virtual centralization. Arrangement of data and processes put together differentiation in the authority of computation. An individual has been direct control on data and procedure in his/her computer [2].The Cloud computing is Internet-based computing, where by shared resources, software and information, are make available to computers and devices on-demand, like the electricity grid. Cloud computing is inventiveness of the fusion of time-honored computing technology and network technology like grid computing, distributed computing parallel computing and so on. It aims to paradigm a accurate system with significant computing capability for the duration of a large number of relatively low-cost computing entity, and using the superior business models like SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service) to distribute the effectual computing capability to end users hand [10].
As the next generation, Cloud Computing has visional architecture of IT Enterprise. In contrast to traditional solutions, where the IT services are under physical, logical and personnel controls [1]. Current cloud service is grant access to web browser or host install application directly [15]. Cloud storage space moves the user's data to large data centers database, on which user does not have any management to manage data [18]. The commercial achievement of Cloud Computing and up to date developments in Grid Computing has been create platform virtualization technology deal with high performance computing [23] by both enterprises and individuals with high service-level requirements [17].
Data security has grow to be predicament of cloud computing like file system, data security, host security. Security is a secure mode practical Internet based on the cloud computing [5]. These are security and trust issue forth, user's data has been liberating to the Cloud and safety measures sphere of the data owner [3]. The data is physically not available to the user the cloud shall provide a way for the user to check if the integrity of his data is maintain [18]. Security model based on key security considerations by looking at a number of infrastructure aspects of Cloud Computing such as SaaS, Utility, Web, Platform and Managed Services, Service commerce platforms and Internet Integration [4] with the rapid development of cloud computing [25]. But it has a negative impact on the effectiveness of caching also other parts of the equation have changed Transmission cost has dropped significantly, and so has the cost to run a cache.

RSA Algorithm
Data security has grown to be predicament of cloud computing like file system, backup, data security etc. Security is a secure mode practical Internet based on the cloud computing. RSA is an asymmetric cryptography algorithm for encrypting data with help of key which is develops by Rom Rivest, Adi Shamir, and Leonard Adleman in 1978. It is based on the presumed complicatedness of factoring large integers. An asymmetric algorithm has set of key one is public and anther one private key The RSA algorithm involves three steps Generation of key Encryption of data Decryption of data RSA involve a key combination such as public key and a private key. The public key can be known to everyone and is used for encrypting messages. Messages encrypted with the public key can only be decrypted using the private key. Example: -we have two companies p and q. p has public cloud along with software, application and data. Company q wants to secure cloud's data from company p. We have tried to secure data of q with the help of RSA algorithm.  Federal information processing standard is like digital signature which used for verification of data. FIPS specifies algorithm for data required digital signature that identity of signature. Digital signature converting string to binary digit. It used for verification of data with key .A hash function is used in signature generate process of data

Google Application Cloud
Google application is a bundle of open recourses for implementing Google application cloud. Google application is services from Google providing autonomously customizable version of several Google products under the custom domain name. It features several Web applications with comparable function to traditional office suite, including Gmail, groups, and Google calendar Talk, Docs and site. In addition to shared apps such as calendar, docs, etc there is Google Apps Market place, which is an application store for Google Apps users. It contains various apps, both free and for a fee [1].

RELATED WORK
Wang et.al focuses on cloud data storage security, which has always been an important aspect of quality of service to ensure the correctness of user's data in the cloud. By utilizing the homomorphism token with distributed verification of erasure-coded data, our scheme achieves the integration of storage correctness insurance and data error localization, i.e., the identification of misbehaving server. They propose new scheme further supports secure and efficient dynamic operations on data blocks, including: data update, delete and append. Extensive security and performance analysis shows that the proposed scheme is highly efficient and resilient against Byzantine failure, malicious data modification attack [1]. Balachandra Reddy et.al has to provide some vendor assurance in service level agreements (SLA) to convince the customer on security issues. SLA has to describe different levels of security and their complexity based on the services to make the customer understand the security policies that are being implemented. It can be helpful for some enterprises to look forward in using the cloud services [2]. Meiko Jensen et.al used to build these cross-domain Internet-connected collaborations [3]. Mehmet Yildiz et.al provides layered security approach for cloud computing infrastructure macro level solution for identified common infrastructure security requirements. This model with a number of emerged patterns can be applied to infrastructure aspect of Cloud Computing as a proposed shared security approach in system development life cycle focusing on the plan-built-run scope [4]. Xiaojun Yu et.al argues that the cloud data security problem should be solved form data life cycle. After analysis of data life cycle model and data security threats, a suggested design process of data security solution is given [8]. Uma Somani et,al have tried to assess Cloud Storage Methodology and Data Security in cloud by the Implementation of digital signature with RSA algorithm [11]. Xiaolin Lu provides dynamically scalable geographic information technology, spatial data, and spatial applications as a web service. GIS web services were designed to provide the hosted spatial data and GIS functionality to integrate the customized GIS applications to perform basic geo-processingtasks, such as address matching, map image display, and routing, without maintaining GIS tools or the associated geographical data [13]. Mahbub Ahmed et.al have objective is served by analyzing different protocols and proposing the one in commensurate with the requirement of the security property like information or data confidentiality along the line of security in Cloud Computing Environment (CCE). To the best of our knowledge, we are the first to derive a secure protocol by successively eliminating the dangling pitfalls that remain dormant and thereby hamper confidentiality and integrity of information that is worth exchanging between the INO and the CSP. Besides, conceptually, our derived protocol is compared with the SSL from the perspectives of work flow related activities along the line of secure trusted path for information confidentiality [14]. Sang-Ho Na et.al are analyze security threats and requirements for previous researches and propose service model and security framework which include related technology for implementation and are possible to provide resource mobility [15]. Bhagyaraj Gowrigolla, et .al a data protection scheme with public auditing scheme is outlined that will address a number of these factors, by providing a mechanism to allow for data to be encrypted in the Cloud without loss of accessibility or functionality for authorized parties. This scheme is not necessarily a replacement for traditional privacy and security measures for data, but rather an enhancement which allows users greater degree of confidence in the adoption of innovative, cost saving Cloud computing technologies [17]. Wayne A. Jansen provides most acute obstacles with outsourced services. Identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses [20]. Daniel Catrein et.al based telecommunication site model has been developed and parameterized with a realistic traffic and cost structure for a Western European operator [22]. Wei-Tek Tsai et.al proposed framework can ease the design of security system in cloud and reduce the complexity of system design and implementation [24]. Joshi Ashay Mukundrao et.al purposes an effective and flexible scheme with two salient features, opposing to its predecessors. Avoiding un-authorized access to user's data by signaling user by sending message to his/her mobile number at the start of transaction [26].
Cong Wang et.al utilize the public key based homomorphism authenticator and uniquely integrate it with random mask technique to achieve a privacy-preserving public auditing system for cloud data storage security and finds that Extensive security and performance analysis shows the proposed schemes are provably secure and highly efficient.
