PassPose: Computer Vision Based Passwordless Authentication - #100
PassPose: Computer Vision Based Passwordless Authentication#100snehaelzadavid06 wants to merge 28 commits into
Conversation
📝 WalkthroughWalkthroughPassPose adds a browser-based gesture authentication application. It uses MediaPipe and webcam input to record gesture sequences, FastAPI endpoints to create and verify passwords, and SQLite for storage. The repository also adds interactive backend scripts, styling, dependencies, configuration, and documentation. ChangesPassPose authentication
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔴 Critical · up to The current API can expose reusable gesture credentials and lets unauthenticated callers replace another user's password. These account-compromise paths should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In @.gitignore:
- Line 5: Ensure setup makes passpose/backend/models/pose_landmarker_full.task
available despite the current ignore rule: either add a targeted negation rule
in .gitignore so the required model is tracked, or update the documented
installation/setup flow to download it before pose initialization. Preserve
ignoring unrelated files under passpose/backend/models/.
In `@passpose/backend/auth_service.py`:
- Line 8: Update the endpoint around save_password so it requires an
authenticated principal with a verified email, rejects unauthenticated or
unverified callers, and derives the email/storage identity from that principal
instead of accepting a caller-selected email.
- Line 8: Update save_password to hash a canonical encoding of the gesture
sequence with the project’s password-hashing library before serialization, and
store only the resulting salted hash rather than the plaintext sequence. Ensure
authentication verification uses the same canonical encoding and
hash-verification API.
In `@passpose/backend/gesture_detector.py`:
- Around line 11-12: Update the ARMS_OUT detection predicate near left_arm_out
and right_arm_out to also require each wrist’s horizontal distance from its
corresponding shoulder to meet the minimum extension threshold, so folded arms
are not classified as ARMS_OUT.
In `@passpose/backend/main.py`:
- Line 43: Update the static-file mount in the application setup so it uses a
dedicated public-assets directory rather than BASE_DIR, ensuring repository
files such as passpose.db are not publicly served. Keep the database outside all
directories passed to StaticFiles.
- Line 66: Update the password creation flow around create_password so the
target account is derived from authenticated server-side state rather than the
client-supplied data.email. Require authentication and authorize the password
sequence update for that account, preventing unauthenticated callers from
selecting another email.
In `@passpose/backend/password_manager.py`:
- Line 10: Update save_password and the authentication flow to store and verify
a salted one-way hash of the gesture sequence instead of serialized raw
sequences. Add migration handling for existing sequence records, converting
valid legacy values to salted verifiers during successful authentication, and
reject unrecognized raw sequence records after rollout.
In `@passpose/backend/pose_detector.py`:
- Line 165: Update save_password to reject empty sequences before persistence,
preserving direct equality verification while preventing empty captures from
being stored. In the pose detector flow around sequence_detector.sequence,
handle the rejected save appropriately so empty captures do not proceed as
successful saves.
In `@passpose/backend/sequence_detector.py`:
- Around line 28-29: Update the NEUTRAL branch in the sequence detector to reset
candidate_count and current_gesture before returning the sequence, ensuring
gesture stability counting restarts and the same gesture can be detected again
after a neutral state.
In `@passpose/backend/test_auth_controller.py`:
- Around line 6-8: In passpose/backend/test_auth_controller.py lines 6-8, move
AuthController and camera initialization, the interactive loop, and cleanup into
main(), invoking it only under an if __name__ == "__main__" guard; apply the
same change to processor and camera initialization, loop, and cleanup in
passpose/backend/test_pose_processor.py lines 6-8 so test collection performs no
webcam or interactive work.
In `@passpose/backend/test_motion.py`:
- Around line 21-35: Prevent pytest collection from executing the runner
scripts: in passpose/backend/test_motion.py lines 21-35, move landmarker
creation, webcam access, and the loop into a direct-execution entry point; in
passpose/backend/test_database.py line 5, guard database initialization with
direct execution or rename the smoke script; in
passpose/backend/test_password.py lines 15-60, eliminate import-time password
writes, use an isolated temporary database, and add assertion-based automated
tests.
In `@README.md`:
- Line 766: Remove the unmatched four-backtick Markdown fence at the end of the
README, leaving surrounding documentation unchanged.
- Line 281: Update the README setup examples to replace the placeholder
repository name and URL with the actual repository URL and its matching clone
directory, including the project tree and git clone commands.
In `@script.js`:
- Around line 41-42: Update the NEUTRAL branch in the gesture detector to clear
candidateGesture, candidateCount, and currentGesture before returning
this.sequence, so a subsequent stabilized gesture is detected independently.
- Around line 459-461: Update the click-handler bindings alongside the existing
landing controls to include nav-landing-btn, nav-signup-btn, and nav-login-btn,
routing each through switchView to the corresponding landing, signup, or login
view while preserving the existing card-button listeners.
- Around line 290-293: Update switchView so that when targetView is neither
signup nor login, it stops every track in mediaStream, clears the camera
element’s srcObject, and resets activeVideoElement; preserve the existing camera
state while switching between the authentication views.
- Line 15: Update the API_URL origin selection to require HTTPS for non-loopback
hosts, while allowing HTTP only for explicit loopback development addresses such
as 127.0.0.1 or localhost. Ensure remote authentication requests cannot use an
http: origin.
In `@style.css`:
- Around line 302-310: Update style.css lines 302-310 for .email-tab input to
use a fluid width with a container-fitting max-width, and update lines 407-412
to wrap or stack the action buttons at narrow viewport widths so all controls
remain reachable. Apply the requested changes at both affected sites.

Prevent horizontal clipping on narrow screens.
At a 320px viewport, the authentication container is narrower than the 260px input plus its tab label and padding. The three 160px action buttons also require at least 510px before container padding. body hides horizontal overflow, so users cannot reach all controls.
