Identity Impersonation Detection in User Sessions

Protecting accounts by detecting subtle behavioral shifts in real time

BY USE CASES

In today’s digital world, attackers increasingly use compromised credentials to impersonate legitimate users during active sessions. Traditional systems may not detect these threats, as logins appear “valid.”

The Challenge:

  • Valid credentials don’t guarantee a valid user

  • Traditional methods struggle with subtle shifts in behavior

  • Static rules miss evolving impersonation techniques

  • Real-time detection requires fast and scalable analysis

Quantum-Inspired Solution

Quantum-inspired models are ideal for detecting tiny but meaningful behavioral changes that indicate impersonation, even when credentials are valid.

Behavioral Fingerprinting via Multi-Dimensional Modeling

HessQ builds a dynamic fingerprint for each user session using typing patterns, navigation flow, mouse movement, timing, and more

When a session starts to deviate from learned patterns, our QUBO engine flags it as a potential impersonation in real time

he model processes live behavior as it happens — allowing instant alerts or multi-factor authentication triggers when a session turns suspicious

QUBO-Based Pattern Deviation Detection
Zero-Lag Alerts

The Results:

  • Detects impersonation within seconds of session deviation

  • Identifies non-obvious behavior changes, like cursor hesitation or page sequence mismatch

  • Reduces user friction by minimizing unnecessary alerts

  • Cuts down the time attackers remain undetected in accounts
