Digital identity verification is now standard practice in conveyancing. However, the technology behind it, including biometrics, NFC chip reading, and liveness detection, is not always well understood.
Here is how it works, what each component does, and why it matters for AML compliance.
How has identity verification in conveyancing changed?
For most of conveyancing’s history, verifying a client’s identity meant checking physical documents in person, such as a passport across a desk, a utility bill, or a driving licence. The process was time-consuming, inconsistent, and increasingly inadequate as fraud became more sophisticated.
Digital identity verification has changed that. Clients can now complete checks remotely using a smartphone, with technology performing in seconds what manual review cannot do reliably. It can confirm not only that a document appears genuine, but that its underlying data is authentic and that the person presenting it is physically present.
In March 2021, HM Land Registry formalised this shift through Practice Guide 81, which introduced the Safe Harbour standard. This set out the requirements for digital identity checks that, if met, protect conveyancers from liability where identity fraud later emerges. Understanding the underlying technology is key to understanding what those requirements mean in practice.
What is biometric verification and how does it work?
Biometric verification forms the foundation of digital identity checks. It uses physical characteristics to confirm that a person is who they claim to be.
In most AML contexts, this involves facial recognition. The client takes a photograph or short video using their device, and the system compares it against the image stored on their identity document. This comparison is carried out algorithmically, analysing the geometry of facial features in a way that is more consistent and reliable than a manual visual check.
Biometric verification is a core requirement of the Safe Harbour standard. The system must confirm that the person presenting the identity matches the image held on the document, rather than simply accepting an uploaded file.
What is NFC chip reading and why is it important?
Modern passports, EU and EEA ID cards, and UK biometric residence permits contain an embedded NFC chip. This chip stores a digital copy of the document’s data, including biometric information and a cryptographic signature from the issuing authority.
When a client places their document against a smartphone, the chip transmits this data. The system can then verify that the digital signature is genuine, confirm that the signing key is valid, and extract the biometric data for comparison against the live image.
This is the most secure form of document verification currently available. While a physical document can be forged, replicating a valid cryptographic signature from an issuing authority is not realistically achievable. For this reason, NFC chip reading is a core part of the Safe Harbour standard.
What is liveness detection and how does it prevent fraud?
Biometric matching and chip reading confirm that a genuine document exists and that the image matches the person presenting it. Liveness detection adds a further layer by confirming that the individual is physically present, rather than using a photograph, mask, or recorded video.
Active liveness requires the user to perform an action, such as blinking or turning their head, to demonstrate that they are present. Because the action is prompted, it can potentially be anticipated and mimicked.
Passive liveness operates in the background without requiring any action from the user. Using machine learning techniques, the system analyses image data to distinguish between a live person and a static or replayed image. Because the user is unaware of the check, passive liveness is generally considered more resilient to spoofing attempts.
Both approaches are used in practice, and understanding the difference is important when assessing providers.
What does the Safe Harbour standard require in practice?
The Safe Harbour standard requires a combination of checks. These include obtaining evidence from a biometric identity document, verifying that document using NFC chip reading, and matching the individual to the document using biometric verification.
For conveyancers acting for sellers, there is an additional requirement to establish a connection between the client and the property.
Where these requirements are met, conveyancers benefit from protection. If a client’s identity is later found to be fraudulent, HM Land Registry will not pursue recourse, provided the checks were carried out correctly.
It is also important to distinguish between standards. The Safe Harbour framework defines the process that must be followed, while the Digital Verification Services Trust Framework governs the providers offering these services. Using a provider listed on the DVS register is increasingly seen as evidence that the underlying technology meets a credible and recognised standard.
Taken together, digital identity verification relies on multiple layers working in combination. Biometric matching confirms identity, NFC chip reading verifies the integrity of the document, and liveness detection ensures the person is genuinely present. The Safe Harbour standard brings these elements together into a defined process that, when followed correctly, provides both compliance and protection.
As expectations continue to evolve, understanding how these components work is essential for assessing providers and ensuring that identity checks are not only completed, but carried out to a standard that stands up to scrutiny.
