arXiv:2605.30848v1 Announce Type: cross Abstract: Agentic LLMs with web search change the threat model for text anonymization: weak contextual cues can become cross-referenceable evidence for re-identification, yet those same details also carry downstream analytic value of the text. Existing defenses either remove explicit identifiers, perturb text for formal privacy, or test rewritten text against non-web inference models, leaving underexplored the operating region between resistance to agentic web-search re-identification and utility retention. We introduce AURA (\textbf{A}nonymization with
The proliferation of advanced agentic AI systems with web search capabilities is rapidly changing the threat landscape for data privacy and anonymization, necessitating new defense mechanisms.
This research addresses a critical vulnerability in data privacy for AI-generated and AI-analyzed text, directly impacting how sensitive information can be safely used and shared in an agentic AI world.
The understanding of text anonymization now extends beyond explicit identifiers to include subtle contextual cues, forcing a re-evaluation of current privacy protocols and opening new avenues for anonymization techniques against agentic re-identification.
