  Trustera, the first functional system that redacts personally identifiable
information (PII) in real-time spoken conversations to remove agents' need to
hear sensitive information while preserving the naturalness of live
customer-agent conversations. As opposed to post-call redaction, audio masking
starts as soon as the customer begins speaking to a PII entity. This
significantly reduces the risk of PII being intercepted or stored in insecure
data storage. Trustera's architecture consists of a pipeline of automatic
speech recognition, natural language understanding, and a live audio redactor
module. The system's goal is three-fold: redact entities that are PII, mask the
audio that goes to the agent, and at the same time capture the entity, so that
the captured PII can be used for a payment transaction or caller
identification. Trustera is currently being used by thousands of agents to
secure customers' sensitive information.
