Sweeney, L. (2013). (2007). A Fully Homomorphic Encryption Scheme. Clearly, these types of use cases require linking potentially sensitive data belonging to the different data controllers. Big data addresses speed and measurability, quality and security, flexibility and stability. Big data security audits help companies gain awareness of their security gaps. Of course, data analytics is a means to an end where the ultimate goal is to provide cyber security analysts with prioritized actionable insights derived from big data. Another important research direction is to address the privacy and the security issues in analyzing big data. doi: 10.1007/978-3-319-41483-6_14, Shaon, F., Kantarcioglu, M., Lin, Z., and Khan, L. (2017). Although the recent research tries to address these transparency challenges (Baeza-Yates, 2018), more research is needed to ensure fairness, and accountability in usage of machine learning models and big data driven decision algorithms. Big Data PhD Thesis Topics is our extremely miraculous thesis preparation service for you to provide highly standardized thesis for your intellectual research. Encrypted storage and querying of big data have received significant attention in the literature (e.g., Song et al., 2000; Hacigumus et al., 2002; Golle et al., 2004; Ballard et al., 2005; Chang and Mitzenmacher, 2005; Kantarcıoğlu and Clifton, 2005; Canim and Kantarcioglu, 2007; Shi et al., 2007; Shaon and Kantarcioglu, 2016). “Privacy-preserving decision trees over vertically partitioned data,” in The 19th Annual IFIP WG 11.3 Working Conference on Data and Applications Security (Storrs, CT: Springer). In addition, in some cases, these techniques require adding significant amount of noise to protect privacy. Cheng, R., Zhang, F., Kos, J., He, W., Hynes, N., Johnson, N. M., et al. These protocols usually leverage ideas from economics and game theory to incentivize truthful sharing of big data where security concerns prevent direct auditing (e.g., Kantarcioglu and Nix, 2010; Kantarcioglu and Jiang, 2012). The statistic shows that 500+terabytes of new data get ingested into the databases of social media site Facebook, every day.This data is mainly generated in terms of photo and video uploads, message exchanges, putting comments … Big data, Technologies, Visualization, Classification, Clustering 1. Therefore, the spam e-mail characteristics may be changed significantly by the spammers as often as they want. Vulnerability to fake data generation 2. As shown by the recent Cambridge Analytica scandal (Cadwalladr and Graham-Harrison, 2018) where millions of users profile information were misused, security and privacy issues become a critical concern. doi: 10.1145/3176258.3176333, Schuster, F., Costa, M., Fournet, C., Gkantsidis, C., Peinado, M., Mainar-Ruiz, G., et al. Once data is encrypted, if the encryption keys are safe, then it is infeasible to retrieve the original data from the encrypted data alone… Abstract of the Dissertation The explosion in the amount of data, called “data deluge”, is forcing to redefine many scientific and technological fields, with the affirmation in any environment of Big Data … A hybrid approach to private record linkage. Kantarcıoğlu, M., and Clifton, C. (2004). For example, a report from Gartner claims (MacDonald, 2012) that “Information security is becoming a big data analytics problem, where massive amounts of data will be correlated, analyzed and mined for meaningful patterns.” There are many companies that already offer data analytics solutions for this important problem. As enterprises data stores have continued to grow exponentially, managing that big data has become increasingly challenging. Establishing a data-friendly culture: For any organization, moving from a culture where people made decisions based on their gut instincts, opinions or experience to a data-driven culture marks a huge transition. (2011). To address the scenarios where machine learning models need to be built by combining data that belong to different organization, many different privacy-preserving distributed machine learning protocols have been developed (e.g., Clifton et al., 2003; Kantarcıoğlu and Clifton, 2004; Vaidya and Clifton, 2005). As big data becomes the new oil for the digital economy, realizing the benefits that big data can bring requires considering many different security and privacy issues. “The limitations of deep learning in adversarial settings,” in IEEE European Symposium on Security and Privacy, EuroS&P 2016 (Saarbrücken), 372–387. This in return implies that the entire big data pipeline needs to be revisited with security and privacy in mind. It has been shown that machine learning results may be used to infer sensitive information such as sexual orientation, political affiliation (e.g., Heatherly et al., 2013), intelligence (e.g., Kosinski et al., 2013) etc. Another important advantage of big data is data analytic. “Privacy preserving keyword searches on remote encrypted data,” in Proceedings of ACNS'05 (New York, NY), 442–455. (2017). “Practical techniques for searches on encrypted data,” in IEEE SP (Washington, DC), 44–55. Many techniques ranging from simple encrypted keyword searches to fully homomorphic encryption have been developed (e.g., Gentry, 2009). The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. 4, 28–34. Possibility of sensitive information mining 5. “A practical framework for executing complex queries over encrypted multimedia data,” in Proceedings on 30th Annual IFIP WG 11.3 Conference on Data and Applications Security and Privacy XXX DBSec 2016 (Trento), 179–195. Zheng, W., Dave, A., Beekman, J., Popa, R. A., Gonzalez, J., and Stoica, I. Our experts will take on task that you give them and will provide online assignment help that will skyrocket your grades. 2.0 Big Data Analytics Springer Publishing Company, Incorporated. Social Media . For example, a patient may visit multiple health care providers and his/her complete health records may not be available in one organization. Information Security is Becoming a Big Data Analytics Problem. Still many challenges remain in both settings. Big Data In It terminology, Big Data is looked as a group of data sets, which are so sophisticated and large that the data can not be easily taken, stored, searched, shared, analyzed or visualized making use of offered tools. (2000). Access Control in Oracle. Androulaki, E., Barger, A., Bortnikov, V., Cachin, C., Christidis, K., De Caro, A., et al. Again differential privacy ideas have been applied to address privacy issues for the scenarios where all the needed data is controlled by one organization (e.g., McSherry, 2009). Over the years, private record linkage research has addressed many issues ranging from handling errors (e.g., Kuzu et al., 2013) to efficient approximate schemes that leverage cryptographic solutions (e.g., Inan et al., 2008). Available online at:, Papernot, N., McDaniel, P. D., Jha, S., Fredrikson, M., Celik, Z. 25, 1849–1862. For example, to address new regulations such as right-to-be-forgotten where users may require the deletion of data that belongs to them, we may need to better understand how the data linked and shared among multiple users in a big data system. Therefore, security is of great concern when it comes to securing big data processes. In this study we focused on data storage security issues in cloud computing and we first provided service models of cloud, deployment models and variety of security issues in data storage in 135 Naresh vurukonda and B. Thirumala Rao / Procedia … For example, different organizations may not want to share their cybersecurity incident data because of the potential concerns where a competitor may use this information for their benefit. In fact, the size of these huge data sets is believed to be a continually growing target. “Smartprovenance: a distributed, blockchain based dataprovenance system,” in Proceedings of the Eighth ACM Conference on Data and Application Security and Privacy, CODASPY 2018 (Tempe, AZ), 35–42.
