# EGXO Privacy QA — Household Egocentric Video Evaluation v2.0.0

Generated: `2026-08-01T03:01:36+08:00`
Status: **PASS**

## Direct answer

Release v2.0.0 contains 89 video-only MP4 files spanning 49 household task families and 35999.980 seconds. Every released file passed stream, metadata, checksum, automated privacy, and manual AI-assisted visual-review gates. No released clip had an unresolved automated face, QR, or visible-personal-information alert.

## Source snapshot

- 1926 metadata records mapped to 1921 unique video objects.
- 105.180562 unique-object hours and 554.487 GiB in the July 31, 2026 export.
- 79 task families and 382 contributors.
- Download state: `complete` with 0 failures.

## Review scope

- 398 provisional clips (30.103238 hours) across 49 lower-risk task families.
- 541842 frames in the dense YuNet plus macOS Vision face pass.
- 158 dense-clear reserve clips (14.049047 hours) across 49 task families advanced to the expensive final gates.
- 1693117 frames in the native-frame YuNet plus macOS Vision pass over the dense-clear reserve pool.
- Dense face parameters: 5.0 FPS at YuNet threshold 0.65; native-frame pass threshold 0.85.
- 50468 frames in the visible-text, QR, and independent Vision pass.
- 5125 alert frames detected; 1887 time-spaced alert frames retained across 95 evidence sheets.
- 89 full-candidate contact sheets reviewed.
- Manual review method: AI-assisted visual inspection by Codex; not an independent human privacy review.
- 145 candidates (13.010454 hours) approved before exact-duration selection.

## Reproducibility

- YuNet model SHA-256: `8f2383e4dd3cfbb4553ea8718107fc0423210dc964f9f4280604804ed2552fa4`
- macOS Vision helper SHA-256: `84f4540deb9bffa4b3ce383db1dfb1aefecd9fc6bb1a9a903a904e5cf085e43b`
- OpenCV: `5.0.0`
- `ffmpeg version 8.1 Copyright (c) 2000-2026 the FFmpeg developers`
- `tesseract 5.5.2`

## Release transformation and verification

- H.264 video only; aspect ratio preserved within a maximum 1920×1080 envelope.
- Audio, subtitle, telemetry/data, and chapter streams removed.
- Source filenames, contributor identifiers, signed URLs, GPS/location keys, device tags, and source timestamps are not distributed.
- 89 file checksums matched; 0 release files contained sensitive metadata keys.
- Restricted media size: 32.857 GiB.

## Access boundary

This is a controlled-access evaluation release, not an open-licensed corpus. Evaluation, model training, commercial use, retention, vendor access, publication, and redistribution rights require a written agreement with EGXO Data.

## Limitation

The procedures reduce privacy risk and found no unresolved face or visible-PII alert in approved release clips. Detector and sampled-review results do not prove the absence of every possible identifier. Suspected issues trigger withdrawal and re-review.
