ABSTRACT
 The dependence of the enterprise on the search engine becomes weaker. At this
stage, many people try to use Google when they encounter problems. With the
development of cloud storage, especially the services of city cloud, industry cloud
and corporate cloud. People will prefer to direct access to the cloud, complete the
information search in the cloud. Cloud growth will also increase with instant
communication tools, not just using search engines. Affected by this situation, the
search engine profit model will change.
 With the establishment of enterprise cloud, industry cloud, city cloud, information is
more systematic and structured, people will be more convenient to access
information. Anyone who wants to find information about a particular aspect can find
all the information about this in cloud. For example, many people are using computer
and feel speed is very slow, so people want to find some ways to improve speed. In
the search process is very east to enter a computer industry cloud, and this cloud not
only includes the computer speed related information, but also includes the
computer daily maintenance, computer equipment self-test related information.

INTRODUCTION
Cloud Storage is a service where data is remotely maintained, managed, a
nd backed up. The service is available to users over a network, which is u
sually the internet. It allows the user to store files online so that the user
can access them from any location via the internet. The provider company
makes them available to the user online by keeping the uploaded files on
an external server. This gives companies using cloud storage services eas
e and convenience, but can potentially be costly. Users should also be aw
are that backing up their data is still required when using cloud storage se
rvices, because recovering data from cloud storage is much slower than lo
cal backup

REQUIREMENT GATHERING AND ANALYSIS
DRAWBACKS OF EXISTING SYSTEM :

PROPOSED SYSTEM :
 In Proposed Cloud Storage system user download the file on the cloud.
Which is means End user is getting the more speed about the Internet
when they will click on the User. Because the cloud is also similar to the
database which is means is also database but having the more space that
a reasonable user getting more speed to search the information as well
as getting more security about the data.
 Objectives are as follows:
1. To provide cloud-based data security.
2. To improve cloud-based file management.
3. To implement efficient file retrievals

METHODOLOGY USED
SOFTWARE REQUIREMENT :
Operating System : Windows Family.
Application Server : XAMPP , Zend Engine.
Web designing languages : HTML5, CSS3.
Scripts : JavaScript, Jquery.
Server-side Script : PHP.
Database : Mysql CLOUD
Database Connectivity : PhpMyAdmin.

HARDWARE REQUIREMENT :
 Processor : Pentium IV or Higher
 Hard Disk : 100 GB Minimum
 RAM : 1GB

TOOL USED
• RAPID PHP
• Color picker
• Page ruler
• CSS lint

CONCLUSION
 In this existing system file owner stored the file into the cloud server. So here
lot of file owners access permission in the same cloud server that time other
file owner will access the other files. That owner will have the chances to
miss use the other owner file. So here we are using the encryption technique
and also two types of keys are generation. When you want access the file
from the cloud server that time that two keys are must so that are security
purpose of key generation. At the same time hacker will hack the key also.
Hacker chances to hack the key also, so here in this proposed system we are
also two key generations at the same time one key is hiding behind of the
image. When file owner want file access from the cloud server that time
must will enter the one key after that image key will be displayed this is
mainly used for the hacker will not access the keys. When hacker hack the
key that time image only will be displayed. This also reduces the
computational time and enhances the security of the files that are uploaded
into the cloud.
