Abstract

This research work presents a solution to the increasing problem of Aadhaar document forgery, which poses challenges in ensuring secure identification, in the form of VeriSphere, a complete multi-modal solution for real-time fraud detection. This framework includes a wide variety of methods such as object detection, optical character recognition (OCR), cryptography and biometrics into a unified decision-making architecture. Object detection is carried out using YOLOv8, which identifies the relevant fields in the document. EasyOCR, along with multi head attention mechanism, is used for performing text extraction from these fields. The validity of the Aadhaar number is checked using the Verhoeff algorithm. QR Code decoding and SSIM based matching provide cross modality verification. Further, other methods like Error Level Analysis (ELA) and ResNet-18 are utilized for detecting the artifacts of tampering. All the verification modules' outcomes are integrated using weighted fusion of fraud scores to reach an authenticity decision. The experimental results proved that VeriSphere offers a 97.3% accuracy, 96.8% precision, 98.1% recall and 97.4% F1-score.
