Data capture (documents, biometrics, device)
The initial step in digital identity verification involves capturing data from multiple sources. This can include images of government-issued documents, selfies for biometric matching, and device-related data such as IP addresses and unique device fingerprints. Each data point collected contributes to a holistic view of the individual’s identity, ensuring accuracy and reliability in the subsequent verification steps.
Document authenticity checks
Following data capture, the system performs an in-depth check of the provided documents to ascertain their legitimacy. This process involves advanced document forensics and the use of OCR to extract and analyze relevant information. Document authenticity checks help identify any signs of tampering or forgery, thereby bolstering the overall security of the verification process.
Biometric matching & liveness
Biometric verification is a cornerstone of modern identity verification systems. Technologies such as facial recognition and fingerprint analysis compare the captured biometric data against stored templates to confirm identity. Liveness detection is an additional layer that ensures the biometric data is being provided by a real, live person rather than a static image or a spoofed sample. These measures significantly reduce the risk of fraudulent activities.
Database & data point validation
A crucial component of digital identity verification is the validation of the collected data against authoritative databases and trusted sources. This step ensures that every piece of information, from document details to biometric markers, is consistent with established records. By cross-referencing multiple data points, the system enhances its accuracy and reliability.
Risk scoring & decisioning
After gathering and validating all necessary data, the system computes a risk score that reflects the likelihood of fraud. This score is derived from algorithms that consider various risk factors, including document quality, biometric match confidence, and unusual activity patterns. Organizations can then use this score to automatically approve, flag, or reject identity verification requests, thereby streamlining operational workflows while minimizing risk.
