Policy-aware Vector Search: A Vision for Fine Grained Access Control in Vector Databases
A new paper from arXiv presents a vision for policy-aware vector search, formalizing the problem of fine-grained access control (FGAC) in vector databases. The authors compare enforcement strategies, present preliminary findings, and identify open challenges for achieving secure, high-performance vector search in security-sensitive applications like RAG and AI pipelines.
New DEC Framework Enables Provenance Reasoning in Knowledge Graphs for Supply Chain
Provenance-enhanced statements like 'according to X, φ' are common in knowledge graphs but current models treat provenance as semantically neutral. A new framework, DEC, interprets provenance predicates as indicators of epistemic stance, grouping statements into cognitive worlds. This allows principled reasoning over attributed content without collapsing disagreements into inconsistencies, with applications in domains like supply chain where multiple parties assert different claims.
Technology Programmable Disclosure: Redefining Privacy in Tech
Programmable disclosure, enabled by zero-knowledge technology, offers a new approach to privacy by allowing users to share only necessary data. This shift can enhance consumer trust and compliance with regulations like GDPR.
