Solution Overview

Problem

The use of multi-function computers in academic examinations is hindered by the risk of cheating due to their potential for accessing prohibited functions or information, such as the internet, which existing technologies fail to adequately address.

Innovation Solution

A system and method utilizing a multi-function computer with an examination application that allows specific functions to be enabled or disabled during an examination, monitoring for unauthorized access, and providing a secure indication of examination completion, including a visual hash or icon that cannot be predicted by users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multi-function computers are used during examinations, then students can access advanced computational functions and tools, but the risk of cheating increases due to ability to access prohibited functions or information

Engineering Contradiction:

Improvecomputational function accessVSAvoidexamination integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The computer system is segmented into multiple independent components: an examination application layer that provides authorized computational functions, a monitoring layer that tracks function access, and a notification layer that alerts proctors. This segmentation allows legitimate academic functions while isolating and controlling potential cheating vectors.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements continuous feedback mechanisms where the examination application monitors its own operation, detects unauthorized function accesses, and provides real-time notifications to proctors. This closed-loop feedback system maintains examination integrity by immediately responding to potential cheating attempts.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If graphing calculators with user-created programs are allowed, then students can explore advanced mathematical concepts, but the ability to store and access user-created content enables cheating

Engineering Contradiction:

Improveprogram execution capabilityVSAvoidcheating risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The harmful capability to execute arbitrary user-created programs is extracted and removed from the examination environment. The examination application provides a controlled subset of computational functions necessary for academic work while eliminating the ability to run unauthorized programs or access stored cheat sheets.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the operational parameters of the computer by dynamically enabling and disabling specific functions based on examination requirements. During examination mode, only approved computational parameters are active, while prohibited functions are restricted, transforming the device from a general-purpose computer to a controlled examination tool.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If wireless communication is enabled in calculators for classroom use, then collaboration and data exchange are improved, but unauthorized communication during examinations becomes possible

Engineering Contradiction:

Improvecommunication capabilityVSAvoidunauthorized information access

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The wireless communication capability is made dynamic rather than static. The examination application can enable wireless communication for authorized purposes during classroom use, but automatically disables or restricts it during examinations. This dynamic control allows the same hardware to serve different educational needs while preventing cheating.

Inventive Principle:

Principle #15Dynamics

4Reliability

If examination mode disables selected functions on calculators, then cheating is prevented, but the device cannot be used for its full educational potential

Engineering Contradiction:

Improveexamination securityVSAvoiddevice functionality

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The examination application is designed as a universal platform that can adapt to different examination types and requirements. It provides a consistent security framework while allowing configuration of which functions are enabled or disabled based on specific examination needs, making the system versatile across various academic contexts.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system and method facilitate the use of a multi-function computer for an examination. An application implementing the method receives a hash input from a user and, upon successful completion of the examination, displays a hash output. The hash output may be displayed as a visual hash. During the examination, the application or system monitors the multi-function computer to determine whether the user has activated, viewed, or launched any prohibited functions or applications on the multi-function computer. If the user views a prohibited function or application, the examination application does not display the hash output. The system and application implement various security measures to prevent spoofing or duplication of the hash output or tampering with the application.
