Solution Overview

Problem

Existing recording systems face difficulties in capturing and decrypting encrypted contact center interactions, particularly in contact centers that use encryption technology, as they lack the necessary encryption keys to access and review the encrypted data streams.

Innovation Solution

A system and method for recording encrypted contact center interactions that includes a control protocol switch interface, an encryption key information buffer, and a data switch interface, which receives an interaction setup signal with encryption key information and a duplicate media stream, allowing the recording module to decrypt the encrypted data stream using the stored encryption key information without being a party to the interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If encryption technology is used to secure contact center interactions, then security and privacy are improved, but existing recording devices are inhibited from capturing and reviewing the interaction data

Engineering Contradiction:
ImprovesecurityVSAvoidrecording capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The recording system performs preliminary actions by obtaining encryption key information from the protocol switch interface before attempting to record the encrypted interaction. The system stores this key information in advance in its storage, enabling it to later decrypt and record the encrypted media stream without being a party to the interaction.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The protocol switch interface acts as an intermediary that provides the recording system with encryption key information without the recording system needing to be a direct participant in the encrypted communication. This mediator enables the recording system to access necessary decryption capabilities while maintaining the security of the original interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a recording system is not a party to the interaction, then system independence and non-intrusiveness are improved, but the system cannot obtain encryption keys needed to decrypt the data stream

Engineering Contradiction:
Improvesystem independenceVSAvoidaccess to encryption keys
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The protocol switch interface serves as an intermediary that bridges the gap between the independent recording system and the encryption key information. Through this intermediary, the recording system can obtain necessary decryption keys without becoming a party to the interaction, thus maintaining both independence and access to information.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary action by proactively obtaining and storing encryption key information from the protocol switch before needing to decrypt the media stream. This preliminary acquisition of keys enables the independent recording system to later access and record encrypted interactions without compromising its non-participant status.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the recording system obtains encryption key information from the protocol switch, then the ability to decrypt and record encrypted interactions is improved, but the system complexity increases due to additional interfaces and key management

Engineering Contradiction:
Improvedecryption capabilityVSAvoidsystem architecture
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system is segmented into distinct functional modules: a control protocol switch interface for obtaining key information, an encryption key information buffer for storing keys, a data switch interface for receiving encrypted streams, and a recording module for decryption and recording. This segmentation allows each component to have a specific, simplified function while collectively achieving the complex capability of recording encrypted interactions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protocol switch interface acts as an intermediary that simplifies the overall system architecture by handling the complex task of encryption key acquisition. This dedicated intermediary component isolates the key management complexity from the rest of the recording system, making the overall architecture more manageable and maintainable.

Inventive Principle:
Principle #24Intermediary (Mediator)
