Title: Nathalie Baracaldo-Angel: Innovator in Data Provenance Defense
Introduction
Nathalie Baracaldo-Angel is a prominent inventor based in San Jose, CA, known for her significant contributions to the field of data security. With a total of four patents to her name, she has made strides in developing innovative methods to detect and mitigate poison attacks using data provenance.
Latest Patents
Her latest patents focus on computer-implemented methods, program products, and systems designed for provenance-based defense against poison attacks. One of her approaches involves receiving observations and corresponding provenance data from various data sources. She determines whether the observations are poisoned based on the provenance data and subsequently removes the poisoned observations from the final training dataset used to train a prediction model. Another implementation addresses provenance-based defense in a fully untrusted data environment. In this method, untrusted data points are grouped according to their provenance signature, which is then utilized to train learning algorithms and generate both complete and filtered prediction models. The performance of these models is compared, allowing for the identification of poisoned data points, which are then removed to create a final prediction model.
Career Highlights
Nathalie is currently employed at International Business Machines Corporation (IBM), where she continues to innovate in the realm of data security. Her work is crucial in enhancing the reliability of data systems and protecting against potential threats.
Collaborations
She collaborates with notable colleagues, including Heiko Hary Ludwig and Bryant R Chen, contributing to a dynamic team focused on advancing technology in data provenance.
Conclusion
Nathalie Baracaldo-Angel's work exemplifies the intersection of innovation and technology in addressing critical challenges in data security. Her patents reflect a commitment to enhancing the integrity of data systems, making her a key figure in her field.
