New advancements in cloud computing technology enable the usage of cloud platforms for business purposes rapidly increasing every day. Data accumulation related to business transactions, Communications, business model architecture and much other information are stored in the cloud platform and access Dubai the business Associates commonly. Considering the security point of view data stored in the cloud need to be highly secured and accessed through authentication. The proposed system is focused on evaluating a cloud integrity auditing model in which the security and privacy preserving system is being audited, privacy is decided using a machine learning algorithm. The proposed model is developed using a hybrid CatBoost algorithm (HCBA) in which the input data is stored into the cloud platform using Bring your own encryption Key (BYOEK). The security of BYOEK model is evaluated and validated with respect to the given test model in terms of Execution time comparison Vs. Data transactions.

Due to expansion of Internet and huge dataset, many organizations started to use cloud. Cloud Computing moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. Due to this cloud faces many threats. In this work, we study the problem of ensuring the integrity of data storage in Cloud Computing. To reduce the computational cost at user side during the integrity verification of their data, the notion of public verifiability has been proposed. Our approach is to create a new entity names Cloud Service Controller (CSC) which will help us to reduce the trust on the Third Party Auditor (TPA). We have strengthened the security model by using AES Encryption with SHA-S12 & tag generation. In this paper we get a brief introduction about the file upload phase, integrity of the file & Proof of Retrievability of the file.

In a Semi-autonomic cloud auditing architecture we weaved in privacy enhancing mechanisms [15] by applying the public key version of the Somewhat homomorphic encryption (SHE) scheme from [4]. It turns out that the performance of the SHE can be significantly improved by carefully deriving relevant crypto parameters from the concrete cloud auditing use cases for which the scheme serves as a privacy enhancing approach. We provide a generic algorithm for finding good SHE parameters with respect to a given use case scenario by analyzing and taking into consideration security, correctness and performance of the scheme. Also, to show the relevance of our proposed algorithms we apply it to two predominant cloud auditing use cases.
