NDS open-sources Rampart, a browser-side PII redaction tool
What happened
On October 10, Hacker News reported that NDS open-sourced Rampart, a browser-side tool that redacts personal information. Redaction of personally identifiable information (PII) happens inside the browser before a message is sent, with no server involved. Detection combines regular expressions and MiniLM: regexes for structured sensitive data, MiniLM for names and street addresses. The reported numbers: the model including the tokenizer is 14.7MB, and p50 latency on browser WebGPU is 3.9ms. The tool is open source, and those detection methods, model size and latency figures are what the report discloses so far.
