Remote Signature Capture for Mobile Transaction Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices limit remote users' ability to complete transactions, such as recurring payments, due to the requirement of a physical signature, which burdens users with printing, signing, and returning documents via mail or fax.
Innovation Solution
A system and method that enables merchants to send a signature request over a network to devices with browsers and touch screens, allowing users to input their signature remotely, which is then routed back for transaction authorization, using a client computing device and server system to facilitate the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical signature is required for transaction authorization, then transaction security is improved, but user convenience and mobility are worsened
Solution Approach 1:
The patent replaces the physical signature with a digital copy or representation of the signature captured through the mobile device's touch screen. The user's signature is captured as graphical data points or coordinates, creating a digital replica that serves the same authorization function without requiring physical paper handling.
Solution Approach 2:
The patent substitutes the mechanical process of writing a signature on paper with an electronic input process through the mobile device's touch interface. The signature capture mechanism uses software to detect and record touch events, replacing the physical act of signing with an electronic equivalent that maintains security while enabling mobility.
2Reliability
If a physical signature is required for transaction authorization, then authentication reliability is improved, but processing time and operational complexity are worsened
Solution Approach 1:
The system creates a digital copy of the signature that can be instantly transmitted and stored, eliminating the time required for physical document handling, mailing, or faxing. The signature data is captured electronically and immediately available for processing.
Solution Approach 2:
The patent implements preliminary authentication by capturing the signature through the mobile device, which inherently verifies the user's identity through device ownership or associated credentials. This preliminary action ensures authentication reliability before the transaction is finalized, reducing later verification time.
3Reliability
If remote users must mail or fax signed documents, then signature verification is improved, but device versatility and remote accessibility are worsened
Solution Approach 1:
The patent makes the mobile device serve multiple functions: it acts as both the authentication tool (capturing the signature) and the communication device (transmitting the signature data). This universal approach eliminates the need for separate physical document handling and verification processes, enabling remote users to complete transactions using only their mobile device.
Solution Approach 2:
The system introduces a digital intermediary layer that captures the signature through the mobile device's interface and transforms it into transmittable data format. This intermediary process replaces the need for physical document intermediaries (paper, mail, fax machines) while maintaining verification reliability through digital data integrity.

AI summary
The present invention is directed to receiving a signature (or other type of verification or confirmation) from a remote user. The present invention enables a merchant to send a signature request over a network to any device having a browser and touch screen or other means for receiving user input. An input area is displayed within the browser on the user's device. When the user inputs a signature (or other form of user input acting as authorization), the signature can be routed over a network back to the merchant to provide authorization for a transaction. Various forms of authentication can be used to verify the identity of the user providing authorization for the transaction.
