Memory Electrical Noise Profiling for Genuine Product Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to distinguish between genuine products and compatible products due to deviations in electrical noise caused by different apparatuses connected to a target product, leading to potential misidentification of compatible products as genuine.
Innovation Solution
An information processing apparatus that determines whether electrical noise from a target product falls within predetermined or enlarged ranges, using a processor to count frequencies within and outside these ranges, and identifies the product as genuine if the sum of frequencies within the enlarged ranges exceeds those outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the predetermined range is enlarged to absorb deviations in electrical noise caused by different apparatuses, then the ability to accommodate variations in capacitance, contact resistance, and thermal characteristics is improved, but the risk of misclassifying compatible products as genuine products increases
Solution Approach 1:
The frequency spectrum is divided into multiple frequency bands, and the evaluation is performed separately for each frequency band. This segmentation allows the system to identify patterns specific to genuine products across different frequency ranges while maintaining the ability to accommodate variations. By evaluating each frequency band independently, the system can distinguish genuine products with consistent noise characteristics across frequencies from compatible products that may show deviations in specific bands.
Solution Approach 2:
The patent introduces a temporal dimension by evaluating electrical noise characteristics over multiple time points or measurement cycles. The system determines whether noise characteristics are consistent across different measurement instances, adding a time-based dimension to the frequency-based analysis. This temporal dimension helps distinguish genuine products with stable noise signatures from compatible products that may exhibit variability.
2Measurement precision
If a strict predetermined range is used to ensure accurate identification of genuine products, then the measurement precision is improved, but the ability to accommodate deviations caused by environmental factors and connected apparatuses deteriorates
Solution Approach 1:
Different frequency bands are evaluated with different criteria and tolerances based on their local characteristics. The system identifies which frequency bands are most indicative of genuine product characteristics and applies stricter evaluation criteria to those bands, while allowing greater flexibility in less discriminative bands. This local differentiation allows the system to maintain high accuracy for critical identification while accommodating variations in non-critical areas.
3Adaptability or versatility
If the evaluation criteria are made more lenient to accommodate compatible products with different characteristics, then the adaptability is improved, but the reliability of genuine product identification deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms where the evaluation results from multiple frequency bands are aggregated and used to make a final determination. The feedback loop allows the system to learn from the overall pattern across all frequency bands rather than relying on a single band's characteristics. This feedback mechanism enhances reliability by cross-validating findings across multiple dimensions while maintaining adaptability to different connected apparatuses.

AI summary
An information processing apparatus includes a processor configured to: obtain electrical noise generated from a memory included in a target product; determine, for each of frequencies obtained by dividing a frequency spectrum of the electrical noise, whether the electrical noise falls within a predetermined range, which is determined in advance for the frequency; determine, if the electrical noise falls outside the predetermined range, whether the electrical noise falls within an enlarged range, which is obtained by enlarging the predetermined range; and determine that the target product is a genuine product if a sum of a number of frequencies at which the electrical noise falls within the corresponding predetermined ranges and a number of frequencies at which the electrical noise falls outside the corresponding predetermined ranges but falls within the corresponding enlarged ranges is larger than a number of frequencies at which the electrical noise falls outside the corresponding enlarged ranges.
