FACIAL VECTOR & MATCHING PIPELINE

How Face Registration & Punch Distance Matching Works

When an employee registers, a 128-dimensional mathematical vector is generated and stored in MongoDB. During punch in/out, the current face vector is compared using Cosine Distance against database vectors to instantly find the nearest employee.

01

Live Camera Stream

Device camera captures high-framerate video stream with zero lag and optimized power consumption.

Stage 01
02

Pose & Orientation Check

Euler angle analysis (Yaw & Pitch) verifies genuine front-facing angle and filters distant background faces.

Stage 02
03

128-D Vector Generation

Facial landmarks are processed to generate a normalized 128-dimensional mathematical vector.

Stage 03
04

Database Vector Storage

During registration, generated facial vectors are saved securely against the employee record in MongoDB.

Stage 04
05

Cosine Distance Matching

During punch in/out, captured vector is mathematically compared against registered company vectors.

Stage 05
06

Nearest Match & Punch Log

Identifies the closest matching employee, determines IN/OUT state, applies cooldowns, and saves the attendance record.

Stage 06
COMPREHENSIVE PLATFORM CAPABILITIES

Built for High-Scale Enterprise Attendance

From guided facial enrollment to automated working-hour payroll calculations and multi-company data isolation, explore the full suite of features.

FACE RECOGNITION

Contactless Facial Attendance

Instant touchless Punch In & Punch Out using live camera streams and sub-second facial vector comparison.

FACE RECOGNITION

Guided Face Enrollment

Step-by-step registration analyzing facial Euler angles (Yaw & Pitch) for Straight, Left, Right, Up, and Down head orientations.

FACE RECOGNITION

128-D Vector Embeddings

Converts captured facial landmarks into normalized 128-dimensional mathematical vectors stored against the employee record.

FACE RECOGNITION

Cosine Distance Vector Matching

During attendance punches, calculates geometric distance between current face vector and database vectors to find the nearest match.

SMART LOGIC

Smart IN / OUT Auto-Alternation

Intelligent state logic that automatically registers the first daily punch as IN and subsequent punches as alternating OUT → IN → OUT.

SMART LOGIC

Duplicate Punch & Cooldown Protection

Built-in rate limiting and cooldown algorithms prevent accidental rapid-fire double punches or duplicate record generation.

SMART LOGIC

Concurrency-Safe Transactions

Atomic database operations and conditional updates protect attendance logs during simultaneous multi-device punch surges.

OPERATIONS

Multi-Timezone Shift Boundaries

Attendance cutoffs, day-shifts, and working hours are computed strictly in each organization's configured local timezone.

ENTERPRISE

Multi-Tenant SaaS Data Isolation

Enterprise multi-company architecture where employee records, facial vectors, and logs are logically scoped by authenticated companyId.

HR & WORKFORCE

Centralized Employee Directory

Comprehensive employee records, departmental hierarchies, shift allocations, face status, and contact directory in one web portal.

HR & WORKFORCE

Leave Requests & Balance Tracking

Employee self-service leave requests with manager approval workflows, automatic balance deductions, and payroll syncing.

OPERATIONS

Workforce Reports & Timesheets

Automated working-hour calculations, monthly attendance summaries, late-in/early-out logs, and CSV/Excel exportable reports.

OPERATIONS

Zero Specialized Hardware Dependency

Deploy instantly on any off-the-shelf Android tablet, iPad, smartphone, or laptop webcam with zero expensive biometric maintenance.

ENTERPRISE

WhatsApp Cloud API & OTP Auth

Meta WhatsApp Cloud API integration for instant OTP-based verification during employee onboarding, login, and security flows.

ENTERPRISE

AES Encryption & JWT Security

End-to-end AES-encrypted payload transit, JWT session management, Google reCAPTCHA bot shield, and private container networking.
