Mobile Device Access Delay for Industrial Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial processes controlled by computers face challenges in preventing unauthorized access, particularly from unreliable or intoxicated personnel, which can lead to accidents and disruptions.
Innovation Solution
A mobile computing device apparatus that delays access to programs based on user interactions, such as touchscreen taps, advertisement acknowledgments, or text recognition, adjusting the delay length and potentially granting access upon reliability verification or payment, to ensure secure and competent operation of industrial processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If access to industrial control programs is immediately granted, then ease of operation is improved, but reliability deteriorates due to potential unauthorized access by unreliable personnel
Solution Approach 1:
The system performs preliminary reliability verification of the user before granting access to the industrial control program. This includes checking user credentials, employment status, and reliability indicators in advance, so that only verified reliable users can access the system, thereby maintaining both ease of operation for authorized users and reliability through pre-screening
Solution Approach 2:
The system introduces an intermediary reliability verification mechanism between the user and the industrial control program. This intermediary layer checks user reliability indicators and acts as a gatekeeper, allowing immediate access for reliable users while blocking unauthorized access from unreliable personnel, thus resolving the contradiction between access speed and security
2Reliability
If access is delayed for reliability verification, then reliability is improved, but productivity deteriorates due to waiting time
Solution Approach 1:
The system performs reliability verification in advance before the user needs to access the industrial control program. User credentials, employment status, and reliability indicators are checked beforehand, so that when the user attempts to access the system, the verification is already complete and access can be granted immediately without delay
Solution Approach 2:
The system uses feedback from pre-verified user profiles and reliability indicators to make rapid access decisions. Once a user's reliability is established through preliminary verification, the system provides immediate positive feedback by granting access without delay, thus maintaining both reliability and productivity
3Reliability
If strict access control is implemented, then reliability is improved, but ease of operation deteriorates due to additional verification steps
Solution Approach 1:
The system implements partial verification by checking only the most critical reliability indicators (employment status, criminal record, substance abuse history) rather than performing exhaustive background checks. This partial verification approach provides sufficient security while minimizing the operational burden on users
Solution Approach 2:
The system allows users to pre-submit their own reliability information and credentials through self-service mechanisms. Users can proactively provide their employment verification, criminal record checks, and other reliability indicators, reducing the need for manual verification steps when they need to access the industrial control program

AI summary
An apparatus for controlling and granting access to computer programs, and/or industrial safety and security, is provided. The apparatus may include a memory configured to store a delay length value, at least one processing core configured to initiate delaying access to at least part of a program, to determine that at least one processing action has been performed on the apparatus by a user, and to adjust, based on the at least one processing action, the length of the delaying of access to the at least part of the program to a non-zero adjusted delay length.
