Discover How Indian Overseas Bank Ensured Fast & Secure Aadhaar Masking Across Digital Workflows
What if your banking operations could mask Aadhaar details automatically, ensuring full compliance, data security, while reducing 80 % of time and increase 90% of perfomance?
Get StartedINTRODUCTION
Indian Overseas Bank (IOB), a leading public sector bank, wanted to enhance the privacy and security of Aadhaar data in its digital workflows. Manual masking or inconsistent processes were prone to errors, lacked standardization, and posed compliance risks. To safeguard sensitive customer data and streamline Aadhaar handling, IOB collaborated with Pixl.ai to implement a robust, automated Aadhaar masking solution.
CHALLENGES
IOB faced several hurdles in processing Aadhaar images securely and efficiently
Data Privacy Compliance
Ensuring Aadhaar masking aligned with UIDAI and government privacy guidelines.
Complex Image Structure
Aadhaar images varied in resolution and format, making consistent barcode/QR detection difficult.
Performance Impact
Image compression and masking could slow down API responses if not optimized.
Integration Constraints
IOB required a wrapper API that worked without changes to their existing core systems.
SOLUTION
How Pixl.ai Aadhaar Masking Solution Helped IOB
Pixl.ai developed a secure, automated Aadhaar masking API that addressed all challenges.
OCR + Pattern Matching:
Hybrid OCR and regex engine to detect Aadhaar numbers and automatically mask the first 8 digits.
Barcode/QR Masking:
Machine vision model to locate and overlay masks on barcodes and QR codes regardless of image orientation.
Selective Extraction:
Logic to extract and return only the last 4 digits in API responses.
Lossless Compression:
Integrated WebP/PNG optimization to reduce image size by up to 60% without affecting quality.
Wrapper API Architecture:
RESTful API that processes images, applies masking and compression, and returns sanitized outputs without client-side code changes.
Scalability:
Asynchronous processing and caching ensured API response times under 2 seconds, even at high loads.
OUTCOMES
Transformational Results
Compliance Achieved:
Fully aligned with Aadhaar masking regulations.
Data Security:
No sensitive Aadhaar data stored in logs or API responses.
Improved Efficiency:
Image size reduced by 50–60%, speeding up uploads and downloads.
Plug-and-Play Integration:
IOB integrated the wrapper API without modifying their core systems.
High Performance:
API handled 1,000+ requests per minute with < 2s response time..
