The Internet has become an essential tool for communication and information access, and with growing demand, new challenges and usage continue to surface. A complimentary tool that came to exist in recent years is Cloud Computing - an economical solution that serves as an alternative to owning and running computing facilities. While cloud computing has many advantages, there are a number of issues that hamper the adoption of cloud computing. Some of the major concerns, can be classified into one of the following groups: traditional security, availability, and third-party data control. The first set of concerns, revolve around security threats that can expose clients private data. The second set of concerns, revolve around the compromise of the operation of the applications in the cloud. Finally, the last set of concerns involve the legal implications of data and applications being held by a third party. Different solutions exist to deal with traditional security, availability, and third-party data control, separately, but one way to handle traditional security, and third-party data control, is through data encryption. The client has to take responsibility for ensuring that the data is setup in such a way, that even if the cloud service provider is compromised, or has a malicious intent, it is not able to get anything from the customers data. Of course, encrypting the data introduces limitations, with varying tradeoffs for different systems. In this work, we use Shamirs Secret Sharing Scheme and a symmetric key cryptographic system (AES) to encrypt data at a field level, such that it can be stored in the cloud without compromising data privacy. Using Shamirs Secret Sharing Scheme to encrypt numeric field values, gives us the ability to perform efficient addition, subtraction, and multiplication on the encrypted numeric field values. We explore two different ways of using Shamir Secret Sharing Scheme and AES, and discuss the advantages and disadvantages of each. We then propose, and complete, a software implementation for the proposed system. The implementation is used in order to compare execution time, memory usage, and bandwidth usage, to the plaintext and MySQL encrypted versions of the database. Analyzing the benchmarks, we can see how the performance varies for different query types when run on tables with different number of records and field types giving the reader an idea about the cost and tradeoffs of the system.

More individuals than ever are utilizing internet technologies to work from home, teach and learn, shop, interact with peers, review medical records, and more. While it is certainly convenient to conduct such tasks via the internet, this increased internet presence has also led to a rise in the search and availability of personal information, which in turn is resulting in more cyber-attacks, privacy breaches, and information leaks. Cyber criminals are using such opportunities to attack governments, organizations, and individuals, making it necessary to anticipate, assess, and mitigate privacy and security threats during this infodemic. The Handbook of Research on Technical, Privacy, and Security Challenges in a Modern World discusses the design and development of different machine learning systems, including next generation applications, in order to mitigate cyber-attacks and address security challenges in everyday technologies. It further explores select methods and algorithms of learning for implementing better security methods in fields such as business and healthcare. It recognizes the future of privacy and the importance of preserving data through recommended practice, feedback loops, and smart agents. Covering topics such as face mask detection, gesture recognition, and botnet attacks and detection, this major reference work is a dynamic resource for medical professionals, healthcare administrators, government officials, business executives and managers, IT managers, students and faculty of higher education, librarians, researchers, and academicians.
