Solution Overview

Problem

The existing operating system digital product key activation process in information handling systems is challenging due to difficulty in detecting failure modes, as there is no tool to determine the operating system SKU or product type, and the presence of a default manufacturing key makes it hard to verify if a unique digital product key has been successfully injected.

Innovation Solution

An injection verification module compares a selected character sequence for the digital product key to the character sequence reported by the operating system image to determine if the key injection procedure was successful, and if not, it identifies the cause of failure by comparing it to a default activation process key.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a default manufacturing key is always injected into the OS image to enable activation, then the activation process can be triggered, but it becomes difficult to detect whether a unique DPK was successfully injected

Engineering Contradiction:
Improveactivation process reliabilityVSAvoidDPK injection verification difficulty
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent extracts and compares only the last N characters (suffix) of the DPK rather than the entire key. This allows verification of injection success without requiring full key exposure or storage, resolving the contradiction by enabling detection with minimal data handling.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary verification mechanism that compares the injected DPK suffix against expected values stored in a lookup table. This intermediary comparison layer enables reliable verification without directly exposing the full DPK or requiring complex query systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If there is no tool to determine the operating system SKU or product type for a particular DPK, then the system remains simple, but failure modes become very difficult to detect

Engineering Contradiction:
Improveverification system complexityVSAvoidactivation failure detection difficulty
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the DPK into a manageable suffix (last N characters) for verification purposes. This segmentation allows failure detection without requiring complete DPK storage or complex SKU mapping tools, reducing system complexity while enabling detection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a simplified copy of the DPK (only the suffix portion) for verification against expected values. This copying approach enables failure mode detection without requiring full DPK management tools or complex SKU determination mechanisms.

Inventive Principle:
Principle #26Copying

3Ease of operation

If the DPK activation process is triggered by injecting a default manufacturing key, then activation can proceed, but there is no way to directly query the system to determine whether it will activate when the system reaches the customer

Engineering Contradiction:
Improveactivation triggeringVSAvoidactivation status verification
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent performs preliminary verification of the DPK injection status by comparing the injected suffix against expected values before the system reaches the customer. This preliminary action enables accurate determination of activation readiness without requiring post-deployment queries.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism that provides verification results by comparing the injected DPK suffix against stored expected values. This feedback loop enables precise determination of activation status without requiring complex query systems or post-deployment testing.

Inventive Principle:
Principle #23Feedback

AI summary

A method, an information handling system (IHS), and a computer program product initiates injection verification to determine whether a key injection procedure to support automated system activation within a target IHS was completed successfully. An injection verification module (IVM) compares a copy of a selected and limited character sequence for a unique digital product key (DPK) utilized during key injection to a character sequence reported by an operating system (OS) image on a selected, target IHS. If the selected character sequence matches the reported character sequence, the IVM identifies the selected information handling system as a “passing” system on which the key injection procedure was successfully performed. If the selected character sequence for the unique DPK does not match the reported character sequence, the IVM identifies the selected information handling system as a “failing” system on which the key injection procedure was not successfully performed.
