Injection Attack
What is an injection attack in identity verification?
How do injection attacks target identity checks?
How can businesses reduce injection-attack risk?
- Capture integrity: Detect signs that the application, device, or capture source has been manipulated
- Session integrity: Associate requests and responses with the current verification attempt and reject unauthorized reuse
- Communication security: Authenticate communicating components and protect data against substitution in transit
- Media analysis: Examine content for evidence of manipulation, replay, or synthetic generation
- Controlled escalation: Request approved additional evidence or review when capture integrity is doubtful

FAQ
How does an injection attack differ from a presentation attack?
A presentation attack places an artifact, such as a printed photo or screen, in front of the capture sensor. An injection attack substitutes data within the digital system. Both can use the same underlying image or video, but they test different protections.
Can liveness detection stop injection attacks by itself?
Some liveness methods can reject injected content, but their effectiveness depends on the attack and integration. A liveness result alone does not establish the capture source. Businesses need evidence about both media analysis and protection of the capture process.
Does presentation-attack testing demonstrate injection resistance?
No. A test against photos, masks, or screen replays establishes performance for those tested presentations. Procurement teams should request separate evidence about digital injection, including the tested attack routes, product configuration, and limitations.
Does an injection attack require a deepfake?
No. An attacker can inject an unmodified stolen selfie, prerecorded video, or genuine document image. Deepfakes provide another possible payload. Controls that only detect AI-generated content leave other forms of unauthorized substitution unaddressed.
Can on-premises deployment prevent injection attacks?
It changes where processing occurs, but a compromised capture application or substituted request can still reach an on-premises service. Evaluate client integrity, request validation, and session protection independently of the server's hosting location.
How should a business test a vendor's injection protections?
Commission authorized testing of the intended application and configuration, covering relevant media types, devices, and attack routes. Review both successful attacks and rejected legitimate sessions. Retest material integration changes because a secure algorithm can still be undermined by an insecure implementation.
