LexisNexis® Risk Solutions uses a statistical approach to data matching to organise data from numerous sources into a single customer view. Each person is given a unique identifier, called a LexID®. The unique identifier is referenced to each data item that relates to the person, providing a single, constantly evolving customer profile.
This patented linking and clustering methodology is applied across a proprietary data universe and multiple credit bureaus and underpins many LexisNexis® Risk Solution products.
ThreatMetrix® – now a LexisNexis® Risk Solutions company, provides a way of detecting fraud, which is completely invisible to the user, by looking at the digital identity that is being used. A digital identity is a network of devices and interactions within a person's online world. The service provides a very effective authentication method to determine if the returning customer is the same person or a fraudster. For new customer interactions it provides reliable information to determine the risk of the person based on their digital identity.
The ThreatMetrix Digital Identity Network analyses 100 million transactions daily to help detect and stop fraud in real time. If a device or other components of a user’s digital identity (e.g. email) become compromised this information is shared within the Digital Identity Network, either from reports of fraudulent activity by customers or by detection of unusual activity. A unique identifier is provided for each identity called a ThreatMetrix ID™ which references 1.4 billion anonymous identities worldwide. Trust and confidence scores are associated with each ThreatMetrix ID™.
