The entire scientific and academic community has been mobilized to gain a better understanding of the COVID-19 disease and its impact on humanity. Most research related to COVID-19 needs to analyze large amounts of data in very little time. This urgency has made Big Data Analysis, and related questions around the privacy and security of the data, an extremely important part of research in the COVID-19 era. The White House OSTP has, for example, released a large dataset of papers related to COVID research from which the research community can extract knowledge and information. We show an example system with a machine learning-based knowledge extractor which draws out key medical information from COVID-19 related academic research papers. We represent this knowledge in a Knowledge Graph that uses the Unified Medical Language System (UMLS). However, publicly available studies rely on dataset that might have sensitive data. Extracting information from academic papers can potentially leak sensitive data, and protecting the security and privacy of this data is equally important. In this paper, we address the key challenges around the privacy and security of such information extraction and analysis systems. Policy regulations like HIPAA have updated the guidelines to access data, specifically, data related to COVID-19, securely. In the US, healthcare providers must also comply with the Office of Civil Rights (OCR) rules to protect data integrity in matters like plasma donation, media access to health care data, telehealth communications, etc. Privacy policies are typically short and unstructured HTML or PDF documents …

Mobile payments are on the rise, and as their popularity is emerging, providers must adhere to security regulations to ensure consumer confidence. There is currently no single regulation specific to mobile wallets, so existing banking transactions are used to secure mobile payment transactions. These financial regulations are large textual documents and require significant manual effort to comprehend and ensure compliance adherence. Thus, it is difficult for both the consumers and providers to understand which specific rules in these regulations apply to their mobile wallet transactions. We have created an integrated knowledge representation of the four main banking regulations that apply to mobile payment Electronic Funds Transfer Act (EFTA), Truth in Lending Act (TILA), Gramm-Leach-Bliley Act (GLBA), and Payment Card Industry Data Security Standards (PCI-DSS). In this paper, we present our framework in detail along with the qualitative and quantitative measures that were used to validate the design against the policies of six major vendors that deal with mobile payments. Our integrated mobile payment knowledge graph, which is available in the public domain, can be used by practitioners to automate mobile wallet transaction compliance in their organization.

Data protection authorities formulate policies and rules which the service providers have to comply with to ensure security and privacy when they perform Big Data analytics using users Personally Identifiable Information (PII). The knowledge contained in the data regulations and organizational privacy policies are typically maintained as short unstructured text in HTML or PDF formats. Hence it is an open challenge to determine the specific regulation rules that are being addressed by a provider's privacy policies. We have developed a semantically rich framework, using techniques from Semantic Web and Natural Language Processing, to extract and compare the context of a short text in real-time. This framework allows automated incremental text comparison and identifying context from short text policy documents by determining the semantic similarity score and extracting semantically similar key terms. Additionally …
