1. INTRODUCTION:
 CLOUD computing presents a new way to supplement the
current consumption and delivery model for IT services based
on the Internet.
 While enjoying the convenience brought by this new
technology, users also start worrying about losing control of
their own data.
 In the context of cloud, accountability is a set of approaches
to addresses two key problems:
 Lack of consumer trust in cloud service providers
 Difficulty faced by cloud service providers with compliance
across geographic boundaries
 Emphasis is on data protection, but the notion of
accountability encompasses more than just privacy

2. ABSTRACT:
 Though the Cloud Service Provider (CSP) gives the privacy
and integrity of the data, this tracks the actual usage of the
user’s data in the cloud by using novel highly decentralized
framework data and policies
 An object-centered approach that enables enclosing our
logging mechanism together with users’ data and policies.
 By leverageing the JAR programmable capabilities to both
create a dynamic and traveling object.
 To strengthen user’s control, also provide distributed auditing
mechanisms.

3. EXISTING SYSTEM:
 Data handling can be outsourced by the direct cloud service
provider (CSP) to other entities in the cloud and theses entities
can also delegate the tasks to others, and so on.
 Entities are allowed to join and leave the cloud in a flexible
manner. As a result, data handling in the cloud goes through a
complex and dynamic hierarchical service chain which does not
exist in conventional environments
 No log and JAR files created for this system
 Data in the cloud may be of encrypted form

4. PROPOSED SYSTEM:
 As the cloud provider gives the access of the resources to the
cloud user’s, the data owner keeps track of usage of their
resources.
 It also provides authenticated usage of data in the cloud.
 Proposed CIA framework provides end-to end accountability
in a highly distributed fashion..
 By means of the CIA, data owners can track not only whether
or not the service-level agreements.

5. Advantage Of Proposed System:
 Novel automatic and enforceable logging mechanism in the
cloud.
 Proposed architecture is platform independent and highly
decentralized, in that it does not require any dedicated
authentication or storage system in place.
 Provide a certain degree of usage control for the protected
data after these are delivered to the receiver
 The results demonstrate the efficiency, scalability, and
granularity of our approach. We also provide a detailed
security analysis and discuss the reliability and strength of
our architecture.

6. Literature Survey
1.Toward Publicly Auditable Secure Cloud Data Storage
Services
The authors propose that publicly auditable cloud data
storage is able to help this nascent cloud economy become
fully established. With public auditability, a trusted entity with
expertise and capabilities data owners do not possess can be
delegated as an external audit party to assess the risk of
outsourced data when needed.
 Such an auditing service not only helps save data owners’
computation resources but also provides a transparent yet
cost-effective method for data owners to gain trust in the
cloud. The author describe approaches and system
requirements that should be brought into consideration, and
outline challenges that need to be resolved for such a publicly
auditable secure cloud storage service to become a reality

7. 2.Identity-Based Authentication for Cloud Computing
The authors propose an identity-based encryption (IBE) and
decryption and identity-based signature (IBS) schemes for
IBHMCC. based on the former IBE and IBS schemes, an
identitybased authentication for cloud computing (IBACC) is
proposed.The author presented an identity based
authentication for cloudcomputing, based on the identity-
based hierarchical model for cloud computing (IBHMCC) and
corresponding encryption and signature schemes
3.Online data storage using implicit security
The authors have described an implicit security architecture
suited for the application of online storage. In this scheme
data is partitioned in such a way that each partition is
implicitly secure and does not need to be encrypted. These
partitions are stored on different servers on the network which
are known only to the user. Reconstruction of the data
requires access to each server and the knowledge as to
which servers the data partitions are stored..

11. MODULES:
1. Cloud Information Accountability (CIA)
Framework:
 CIA framework lies in its ability of maintaining lightweight and
powerful accountability.
 By means of the CIA, data owners can track not only whether
or not the service-level agreements are being honored, but
also enforce access and usage control rules as needed.

12. 2. Distinct mode for auditing:
Push mode:
 The push mode refers to logs being periodically sent to the
data owner or stakeholder.
Pull mode:
 Pull mode refers to an alternative approach whereby the user
 (Or another authorized party) can retrieve the logs as needed.

13. 3. Logging and auditing Techniques:
1. The logging should be decentralized in order to adapt to the
dynamic nature of the cloud..
2. Every access to the user’s data should be correctly and
automatically logged.
3. Log files should be reliable and tamper proof to avoid illegal
insertion, deletion, and modification by malicious parties.
4. Log files should be sent back to their data owners periodically
to inform them of the current usage of their data.
5. The proposed technique should not intrusively monitor data
recipients’ systems.

14. 4. Major components of CIA:
 There are two major components of the CIA, the first being
the logger, and the second being the log harmonizer.
 The logger is strongly coupled with user’s data (either single
or multiple data items).
 It may also be configured to ensure that access and usage
control policies associated with the data are honored.

15. CONCLUSION
 Innovative approaches for automatically logging any access
to the data in the cloud together with an auditing mechanism
is proposed.
 Approach allows the data owner to not only audit his content
but also enforce strong back-end protection if needed.
Moreover, one of the main features of our work is that it
enables the data owner to audit even those copies of its data
that were made without his knowledge.
 In the future, planed to refine our approach to verify the
integrity and the authentication of JARs
