Analyzing a Computer’s Ability to Monitor Data Provenance Events
As the amount of data in the world continues to increase, the ability to track data provenance becomes more and more important. In order to tackle this issue, a tool, Knowledge Network Programming System (KNPS), was built to track data history. To do this, KNPS monitors a computer’s processes and …

Unsupervised Workflow Discovery in Provenance Graphs
Data is an ever-expanding part of life in today’s world. Understanding the origin and the history of data - a concept known as data provenance - can thus be extremely important. In this thesis, we first address the need for a data provenance knowledge graph system, then address the need for being …

Big Data Analytics in Static and Streaming Provenance
… ecological relationships at unprecedented scale. Data provenance traces relationships of entities over time, thus providing a unique view on over-time behavior under study. However, provenance can be overwhelming in both volume and complexity; the now forecasting potential of provenance creates …

Trustworthy History and Provenance for Files and Databases
… integrity assurances for the history of data in an untrusted environment. We show that it is possible to provide strong integrity assurances for data history, without incurring high performance overheads, or using costly trusted hardware. We first focus on file systems and data …

Leveraging metadata in NoSQL storage systems
We present Wasef, a metadata system for NoSQL data stores. Wasef allows us to support important features such as data provenance, flexible data operations, and new administration tools. Our system has a general design that can be made compatible with most NoSQL data stores without imposing heavy …

Uncertainty Quantification in Security Aware Data Pipelines
… systems, the diversity and volume of data have expanded. Proper management of sensitive information collected and processed through data pipelines is crucial. Traditional data pipelines usually perform error analysis of the final pipeline output after a detection model. As a result, …

Constructing provenance-aware distributed systems with data propagation
… architecture to maintain a detailed history or provenance of the data processed by it? Most existing distributed architectures can perform only one operation at a time. While they are capable of tracing possession of data, these architectures do not always track the network of operations used to …
