Loan Pre-Approval Data Reconstruction for Secure Auto Financing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automobile financing transactions, there is a challenge in securely sharing information among stakeholders while maintaining customer privacy and preventing fraud, especially in non-contemporaneous or near-contemporaneous financing and payment scenarios.
Innovation Solution
The use of specially configured data structures with cryptographic transformations, including multi-layer encryption and secure data encapsulation processors, to securely share and manage loan transaction information, ensuring that sensitive details are revealed only at appropriate stages of the transaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-layer cryptographic mechanisms are implemented to securely share loan transaction information, then security and privacy are improved, but device complexity increases
Solution Approach 1:
The patent segments loan transaction information into multiple data portions, where each portion is encrypted with a different cryptographic key. This allows selective disclosure of information - for example, a dealer can access only certain portions while the borrower's full information remains protected until later stages of the transaction process.
Solution Approach 2:
The patent implements nested encryption structures where data portions are encrypted with layering - outer layers can be decrypted by certain parties at certain stages, revealing inner layers that require different keys. This nested structure enables controlled information release while maintaining security throughout the transaction lifecycle.
2Reliability
If cryptographic transformations are applied to protect customer information, then privacy is improved, but information accessibility deteriorates
Solution Approach 1:
The patent performs preliminary encryption of loan transaction information into multiple data portions before the actual transaction occurs. This allows the information to be prepared and secured in advance, with different portions made accessible to different parties at appropriate times during the transaction process, thus maintaining privacy while ensuring timely accessibility.
Solution Approach 2:
The patent introduces a data processing system as an intermediary that manages the encrypted data portions and controls their release. This intermediary system ensures that information is disclosed only to authorized parties under appropriate conditions, balancing privacy protection with information accessibility needs.
3Reliability
If data portions are released at different stages of transaction, then fraud prevention is improved, but transaction time increases
Solution Approach 1:
The patent implements a dynamic information release mechanism where encrypted data portions are decrypted and made accessible based on the transaction stage and authorization status. This dynamic approach allows the system to adapt information accessibility to the current transaction state, enabling fraud prevention through staged disclosure while minimizing delays through automated key management and efficient decryption processes.
Data Source
AI summary
A computer system for provisioning automobile financing is described, including: at least one data interface adapted to receive partial or masked pre-approval data set from a backend computing device associated with a financial institution, the partial or masked pre-approval data set configured such that pre-approval data set associated with a potential loan transaction is not independently accessible by the computer system; the at least one data interface adapted to receive, from a customer or a customer device, a corresponding identifier or portion of pre-approval data set that complements the partial or masked pre-approval data set; an integration engine adapted for combining the partial or masked pre-approval data set and the corresponding identifier or portion of pre-approval data set to regenerate the complete pre-approval data set associated with the potential loan transaction; a loan provisioning engine adapted for provisioning the loan transaction in accordance with the complete pre-approval data set.
