Card Reader Encryption via Magnetic Fingerprinting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card readers are vulnerable to phishing and spoofing scams that exploit the information stored on data cards, as they rely on conventional magnetic read heads that can extract data without adequate security measures.
Innovation Solution
A card reader system equipped with a magnetic sensor, analog-to-digital converter, and processor that generates a magnetic fingerprint from the intrinsic magnetic characteristic of data cards, encrypts the data, and outputs the encrypted information, while also being shielded against tampering through security enclosures and encryption techniques like DES and DUKPT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional magnetic read heads are used to read data cards, then data extraction is simple and cost-effective, but security is compromised making the system vulnerable to phishing and spoofing scams
Solution Approach 1:
The patent segments the card reading system into multiple functional components: a magnetic sensor for reading data, an analog-to-digital converter for signal conversion, and a processor for encryption. This segmentation allows each component to be optimized for its specific function while collectively providing enhanced security through encryption of the extracted data.
Solution Approach 2:
The patent introduces an intermediary processing layer between the magnetic sensor and the output interface. This intermediary includes an analog-to-digital converter and a processor that encrypts the data before output. This intermediary layer prevents direct access to raw magnetic stripe data, thereby securing the system against phishing and spoofing attacks while maintaining the simplicity of the overall card reading process.
2Reliability
If data is encrypted within the read head, then security against phishing and spoofing is improved, but the device complexity increases due to additional components like analog-to-digital converters and processors
Solution Approach 1:
The patent merges the encryption functionality directly into the read head device by integrating an analog-to-digital converter and a processor within the same housing. This consolidation provides security benefits while minimizing the increase in device complexity by combining multiple functions into a single integrated unit rather than adding separate external components.
3Reliability
If encryption is implemented in the card reader system, then protection of personal financial information is improved, but the ease of operation may be reduced due to additional processing steps
Solution Approach 1:
The patent implements self-service encryption where the read head automatically encrypts the data extracted from the magnetic stripe without requiring user intervention. The analog-to-digital converter and processor handle the encryption process autonomously, maintaining ease of operation for the user while providing robust protection for personal financial information.
