SIV access through Browser Advantages

• Simpler credential collection

– Prompt, Grammar ASR, SIV all controllable via VXML

• Reduced Customer Perceived latency

– Streaming Authentication – Parallel ASR/SIV

• Potential for improved ASR/SIV accuracy

– Shared information between engine(s)

• Single engine for app developers

– Fewer moving parts

• Local/Offline processing available

SIV access through Browser Disadvantages

• “Security Concerns”

– Access Controls for SIV now applied in call center – Audio in Transit – Comparison occurring in call center vs. data center

• Less extensible for non-call center apps?

– Agent access to SIV – Web based access to SIV

• Lowest common denominator?

– Some defined functionality may not be available from some vendors – Some vendors may have functionality beyond what is in the spec

• SIV Results/Config exposed in the call center

– Solution might be through encryption of messages
