Bone Conduction Biometric Verification for Secure Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic payment systems lack secure verification methods, particularly in scenarios where traditional biometric authentication may not be feasible or effective, such as in noisy environments, necessitating a more reliable and innovative approach to authenticate payers and complete transactions.
Innovation Solution
The method involves receiving an acoustic wave signal encoded with a payer's identifier and transaction information, retrieving the payer's bone conduction characteristic, and verifying the payer based on this characteristic to allow or deny transaction completion, utilizing a pre-determined carrier signal and bone conduction characteristics stored in a database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional biometric authentication is used, then verification can be performed, but it is affected by environmental noise and may not be reliable in noisy environments
Solution Approach 1:
The patent replaces traditional acoustic-based biometric authentication with bone conduction-based authentication. Bone conduction transmits vibrations through the skull bones directly to the inner ear, bypassing the external ear canal and eardrum. This substitution of the authentication mechanism eliminates susceptibility to environmental noise interference while maintaining verification reliability
Solution Approach 2:
The patent introduces bone conduction as an intermediary medium for transmitting authentication signals. By using the skull bones as a transmission medium rather than air conduction through the ear canal, the system creates a protected pathway that isolates the authentication process from external noise interference
2Loss of information
If acoustic wave signals are used for transmission, then data can be communicated, but the signals may be interfered with by environmental noise
Solution Approach 1:
The patent substitutes air conduction with bone conduction for signal transmission. The authentication signals are transmitted through vibrations of the skull bones rather than through air molecules, eliminating the harmful effect of environmental noise on signal integrity while maintaining effective data communication
3Reliability
If secure verification methods are implemented, then transaction security is improved, but the system complexity increases
Solution Approach 1:
The patent changes the fundamental parameter of signal transmission from acoustic conduction through air to mechanical conduction through bone. This parameter change enables secure verification through unique bone conduction characteristics while maintaining relatively simple system implementation using existing bone conduction technology and signal processing methods

AI summary
Methods, computer program products, systems are provided for securely performing electronic transactions over a network. An acoustic wave signal is received. The acoustic wave signal is encoded with at least an identifier of a payer of a transaction and transaction information of the transaction. The identifier of the payer and the transaction information is then obtained from the acoustic wave signal. A bone conduction characteristic of the payer is retrieved based on the identifier of the payer and based on the received bone conduction characteristic of the payer, the payer is verified. Completion of the transaction is allowed based on the transaction information in response to the payer being verified.
