SSFTD Software Update Automation via Local Reference Stacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face significant challenges in efficiently and reliably updating software on a large number of self-service financial transaction devices (SSFTDs) due to network bandwidth limitations and the complexity of the installation process, which can lead to errors, especially when human intervention is required.
Innovation Solution
The method involves creating a reference software stack that can be imaged and sent to SSFTDs, allowing them to generate their own stack locally, using delta patch files for larger updates, and employing a logically-protected region on the hard drive for storing installation components and instructions, enabling automated and error-reduced updates without the need for a human operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software upgrades are distributed over the network to all SSFTDs, then all SSFTDs can receive updates, but network bandwidth limitations make this impractical or economical
Solution Approach 1:
The patent segments the software update distribution process into local and network components. A master reference stack is maintained locally at each SSFTD, while only incremental updates (deltas) are transmitted over the network. This segmentation allows the system to avoid transmitting complete software stacks repeatedly, significantly reducing network bandwidth consumption while ensuring all SSFTDs receive necessary updates.
Solution Approach 2:
The patent implements preliminary action by pre-distributing a complete reference software stack to each SSFTD via removable media before network connectivity is established. This initial local copy serves as a baseline, allowing subsequent updates to be applied locally without requiring repeated network transmissions of the entire software stack.
2Ease of manufacture
If a complex installation sequence is performed locally at each SSFTD, then software can be installed, but the process is prone to error and not reliably repeatable
Solution Approach 1:
The patent implements self-service by enabling each SSFTD to automatically perform software installation and updates using locally stored reference stacks and update deltas. The system uses automated task sequences that execute without human intervention, comparing the current software state against the reference stack and applying only necessary changes. This eliminates manual installation errors and ensures consistent, repeatable results across all SSFTDs.
Solution Approach 2:
The patent incorporates feedback mechanisms where the SSFTD continuously compares its current software configuration against the stored reference stack. This feedback loop identifies discrepancies and automatically triggers the appropriate correction actions, ensuring the system self-corrects any drift from the intended software state and maintains reliability across distributed installations.
3Ease of operation
If a human service operator is involved in locally managing the installation sequence, then installation can be performed, but potential errors are even more likely
Solution Approach 1:
The patent eliminates human involvement in the installation process by implementing automated task sequences that run locally at each SSFTD. The system automatically retrieves updates, compares them against the reference stack, and applies changes without human intervention. This automation removes the source of human error entirely while maintaining ease of operation through unattended execution.
Solution Approach 2:
The patent introduces an intermediary automated installation agent that mediates between the update source and the SSFTD software environment. This agent executes predefined task sequences, manages the installation process, and handles error correction automatically, replacing human operators and eliminating their potential for error while maintaining the installation process.
4Stability of the object's composition
If all SSFTDs are upgraded within a short window of time, then consistent user experience is achieved, but the burden on service providers becomes overwhelming
Solution Approach 1:
The patent segments the software distribution architecture into locally autonomous SSFTDs that each maintain their own reference stack and perform updates independently. This segmentation allows updates to be propagated through the network gradually as SSFTDs come online, rather than requiring simultaneous coordination of all devices. Each unit upgrades at its own pace while maintaining consistency with the reference standard, reducing the operational burden on service providers.
Solution Approach 2:
The patent implements universality by creating a single master reference software stack that serves as the authoritative source for all SSFTDs. This universal reference can be copied to any number of devices without modification, allowing consistent user experience across the entire fleet while simplifying the service provider's maintenance burden through standardized, repeatable distribution processes.

AI summary
Methods, apparatuses, and systems for network enhanced controls of software updates received via a computer-readable medium are described. A request for identification information of an image version may be sent from a first computer to a second computer. The first computer may receive identification information of the image version. The first computer may determine whether data representing the image version is stored on a removable computer-readable storage medium. Responsive to determining that data representing the image version is stored on the removable computer-readable storage medium, the first computer may load the data representing the image version from the removable computer-readable storage medium.
