For encryption of information to be an effective strategy for keeping up data privacy or security, decryption keys must be separated securely from the cloud environment to ensure that only an affirmed party can translate or decode information, this imperative in encryption innovation. An additional test around encryption in the cloud is to expect controls of encoded data or information such that plan or meaningful data, can be recovered and be used to break the cipher [27] implies that cloud providers must not be permitted limitless ability to store and archive encrypted …show more content…

Grid Computing versus Cloud
Cloud distributed computing is the use of a 3rd party service (Web Services) to perform handling needs. Cloud depicts Internet. With cloud distributed computing, organizations can scale up as far as possible in a minute without putting resources into new infrastructure or framework. Computing of cloud is a favorable position to small and medium-sized organizations. On a very basic level, customers use what they require on the Internet and pay only for what they use.
Computing of cloud joins Infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) and in addition Web 2.0. Generally, cloud computing customers don't assert the physical infrastructure, rather renting so as to maintain a strategic distance from capital consumption use from a third-party provider. They use resources as a service and pay just for resources that they use. Various cloud distributed computing offerings use the utility computing model, which is basically proportional to how conventional utility services. Sharing "perishable and elusive" multiple tenants can enhance use rates, as servers are not pointlessly left idle, which can decrease costs essentially while extending the pace of utilization improvement or change [12,

Furthermore, the number of communications between C1 and C2 is constant. To perform range queries over encrypted integers in the cloud, we assume the data owner has encrypted and outsourced their database to C1. Integers in particular are encrypted using their bit representation. The lower and upper bound of the query are encrypted in a similar fashion. The comparison protocol is executed for every record.

A. Encryption Concept Encryption is the process of using a formula called the cryptographic algorithm to translate plain text into an incomprehensible code and later convert it back to plain text [3]. The text relies mainly on the use of a numeric value, called the key, which is part of the encryption algorithm. B. Cloud Computing Concept Cloud computing has become part of users' lifestyles because sources such as data storage, and computer systems are accessible as needed through networks that offer various computing services that do not require resources located on customers' personal computers, such as space resources for data storage[4] .

This model provides highest level of control, flexibility and management over the IT resources • Platform as a Service (PaaS): Platform as a service removes the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allow you to focus on the deployment and management of your applications. This model helps one to be more efficient. • Software as a Service (SaaS): This is top layer of cloud computing platform. This platform is typically built on top of a Platform as a service solution.

As the technology marches forward introducing every time we turn around a new, improved device or computer program this constant adaptation undoubtedly affects every part of our financial life. One must agree that iPhones, for example, which become almost absolute after two or three years of use due to evolving computer science must create an economic burden for some American families. The same way, all hospitals must struggle with maintaining technological sharpness while assuring the presence of digital innovation despite the existing financial limitations. To illustrate the monetary hindrance in the VA Hospital, I would like to bring to the attention a problem related to cloud-based application necessary for managing and storing information.
