无名 wuming

The Tao that can be told is not the eternal Tao. The name that can be named is not the eternal name. The nameless is the beginning of heaven and earth.

wuming (无名 -- "The Nameless") is a Go library for detecting and removing Personally Identifiable Information (PII) from text. It supports global PII standards across multiple locales and provides pluggable detection and replacement strategies via a hexagonal architecture.

Key Features

• Multi-locale detection -- built-in support for common (global), US, NL, EU, GB, DE, and FR PII patterns
• Pluggable replacers -- redact, mask, hash, or bring your own replacement strategy
• Hexagonal architecture -- clean separation between domain logic and adapters for easy extension
• Concurrent processing -- detectors run in parallel with configurable concurrency limits
• Confidence scoring -- each match carries a confidence score for fine-grained filtering
• Checksum validation -- Luhn, mod-97, 11-proof, mod-11, and other algorithms reduce false positives

Quick Example

package main

import (
    "context"
    "fmt"

    "github.com/taoq-ai/wuming"
)

func main() {
    w := wuming.New(
        wuming.WithLocale("nl"),
    )

    result, err := w.Process(context.Background(),
        "Call me at 06-12345678 or email john@example.com",
    )
    if err != nil {
        panic(err)
    }

    fmt.Println(result.Redacted)
    // Output: Call me at [PHONE] or email [EMAIL]
}
