RF Physical Medium for Temporary Account Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for granting temporary access to an account are inefficient and insecure, requiring significant computing resources, involving permanent user additions, and allowing unauthorized transactions due to lack of transaction control.
Innovation Solution
A physical medium, such as a transaction card, is temporarily paired with an account, allowing access based on specific parameters, which can be automatically unpaired after a time or upon parameter violations, enabling secure and controlled transactions without permanent user additions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical medium is permanently associated with an account, then access security is improved, but flexibility and resource efficiency deteriorate due to inability to revoke access
Solution Approach 1:
The patent implements dynamic pairing between physical mediums and accounts, where the association is temporary and can be automatically revoked based on time expiration or parameter violations. This transforms the static permanent association into a dynamic temporary one, simultaneously improving security through revocability and maintaining flexibility through automatic unpairing mechanisms.
2Ease of operation
If permanent user additions are made to an account, then access control is simplified, but computing resources are wasted due to inability to remove users
Solution Approach 1:
The system implements self-service automatic unpairing where the pairing mechanism itself handles the revocation of access based on pre-set time parameters or violation detection. This eliminates the need for manual user removal operations, reducing computing resource waste while maintaining operational simplicity through automated lifecycle management.
3Ease of operation
If unrestricted access is granted to an account, then ease of use is improved, but security and fraud prevention deteriorate
Solution Approach 1:
The patent changes the parameters of access control by introducing time-based expiration and transaction-type restrictions. Instead of binary restricted/unrestricted access, the system implements conditional access where the physical medium can perform transactions only within specified time windows and only for approved transaction types, thereby maintaining ease of use while preventing fraud through parameter-based control.
4Reliability
If manual access management is used, then security control is improved, but productivity and efficiency deteriorate due to significant computing resources required
Solution Approach 1:
The system implements self-service automatic unpairing where the pairing mechanism itself handles the revocation of access based on pre-set time parameters or violation detection. This eliminates the need for manual user removal operations, reducing computing resource waste while maintaining operational simplicity through automated lifecycle management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution conserves computing resources, enhances security by limiting transaction types and durations, and reduces fraud by automatically managing access and transaction authorization.
Implementation Method 1
a physical medium includes a radio frequency (RF) component; detect, via the RF component, that the physical medium is within a communicative proximity of a first user device or a first medium associated with a first account
Data Source
AI summary
In some implementations, a physical medium may include a radio frequency (RF) component and an integrated circuit (IC) chip component. The physical medium may be configured to detect, via the RF component, that the physical medium is within a communicative proximity of a first user device or a first medium associated with a first account. The physical medium may communicate, via the RF component, with the first user device or the first medium based on detecting that the physical medium is within the communicative proximity of the first user device or the first medium. The physical medium may configure the IC chip component to indicate that the physical medium is paired with the first account. The physical medium may transmit, via the RF component or the IC chip component and to a terminal, an indication that the physical medium is paired with the first account.
