# Data Anonymization Summary

This document summarizes all changes made to anonymize personal and specific data throughout the Bose SoundTouch Go client codebase.

## Overview

All specific IP addresses, device IDs, device names, and other potentially personal information have been replaced with generic, example values to protect privacy while maintaining the functionality and usefulness of the documentation and test examples.

## Changes Made

### IP Addresses

**Original → Anonymized:**
- `192.168.178.35` → `192.168.1.10`
- `192.168.178.28` → `192.168.1.10`
- `192.168.1.100` → `192.168.1.10`
- `192.168.1.101` → `192.168.1.11`
- `192.168.1.102` → `192.168.1.12`

### Device IDs

**Original → Anonymized:**
- `A81B6A536A98` → `ABCD1234EFGH`
- `1234567890AB` → `ABCD1234EFGH`
- `1234567890AC` → `ABCD1234EFGH`

### Device Names

**Original → Anonymized:**
- `Sound Machinechen` → `My SoundTouch Device`

### MAC Addresses

**Original → Anonymized:**
- `A81B6A536A98` → `AA:BB:CC:DD:EE:FF`
- `A81B6A849D99` → `AA:BB:CC:DD:EE:FF`
- `A8:1B:6A:53:6A:98` → `AA:BB:CC:DD:EE:FF`
- `A8:1B:6A:84:9D:99` → `AA:BB:CC:DD:EE:01`

## Files Modified

### Documentation Files
- `README.md` - Updated all IP addresses and device examples
- `Makefile` - Updated example IP addresses in help text
- `docs/SYSTEM-ENDPOINTS.md` - Anonymized all example data
- `docs/VOLUME-CONTROLS.md` - Updated device IDs and IP addresses
- `docs/KEY-CONTROLS.md` - Updated IP addresses
- `docs/BASS-CONTROLS.md` - Updated device IDs
- `docs/HOST-PORT-PARSING.md` - Updated IP addresses and device names
- `docs/STATUS.md` - Updated IP addresses

### Source Code Files
- `cmd/soundtouch-cli/main.go` - Updated all example IP addresses in help text
- `cmd/soundtouch-cli/main_test.go` - Updated test IP addresses

### Test Data Files
- `pkg/client/testdata/info_response.xml` - Updated device ID, name, and network info
- `pkg/client/testdata/info_response_st20.xml` - Updated device ID and network info
- `pkg/client/testdata/capabilities_response.xml` - Updated device ID
- `pkg/client/testdata/name_response.xml` - Updated device name
- `pkg/client/testdata/networkinfo_response.xml` - Updated device ID and network info
- `pkg/client/testdata/clockdisplay_response.xml` - Updated device ID

### Test Files
- `pkg/client/client_test.go` - Updated device IDs, names, and IP addresses
- `pkg/client/system_test.go` - Updated device IDs and IP addresses
- `pkg/client/balance_test.go` - Updated device IDs in test responses
- `pkg/client/bass_test.go` - Updated device IDs in test responses
- `pkg/models/networkinfo_test.go` - Updated device IDs and network info

## Anonymization Strategy

### IP Addresses
- Used standard RFC 1918 private IP ranges (192.168.1.x)
- Maintained realistic network structure (same subnet for related devices)
- Used sequential numbering (.10, .11, .12) for clarity

### Device IDs
- Used generic alphanumeric pattern `ABCD1234EFGH`
- Maintained consistent usage across all files
- Preserved original length and format

### Device Names
- Used generic but descriptive names like "My SoundTouch Device"
- Removed any potentially personal identifiers

### MAC Addresses
- Used standard placeholder format `AA:BB:CC:DD:EE:FF`
- Used sequential variants (EE:01) when multiple addresses needed
- Maintained proper MAC address format

## Verification

After anonymization:
- ✅ All tests continue to pass
- ✅ All builds succeed
- ✅ Documentation remains accurate and useful
- ✅ No personal data remains in examples
- ✅ Functionality is preserved

## Benefits

1. **Privacy Protection**: No personal network information exposed
2. **Professional Examples**: Clean, generic examples suitable for public documentation
3. **Consistency**: Uniform use of example data across all files
4. **Maintainability**: Easy to identify example vs. real data

## Standards Used

- **IP Addresses**: RFC 1918 private ranges (192.168.1.x/24)
- **Device IDs**: Generic alphanumeric placeholders
- **MAC Addresses**: Standard placeholder format
- **Device Names**: Generic descriptive names

All changes maintain the original functionality while ensuring no personal or specific network information is exposed in the codebase.
