Solution Overview

Problem

Deep learning-based indoor localization frameworks are vulnerable to spoofing and jamming attacks, which can significantly degrade localization accuracy and pose security risks in critical applications.

Innovation Solution

A secured convolutional neural network (S-CNNLOC) is configured to resist such attacks by generating a second training data set using statistical distribution models and adding random or temporally correlated offset values, enhancing the neural network's resilience to interference.

Solution Approach 1:

The patent applies preliminary action by generating a second training data set before deployment using statistical distribution models of radio signal strengths. This pre-processing step creates augmented training data that accounts for potential attack scenarios, enabling the neural network to learn resilient features in advance rather than reacting to attacks during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes parameters by applying random or temporally correlated offset values to the training data, simulating various attack conditions. This parameter transformation allows the neural network to be trained on diverse signal strength variations, improving its ability to distinguish between legitimate signal changes and malicious attacks.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If statistical distribution models and offset values are added to generate second training data set, then resilience to attacks is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent uses copying by creating a second training data set that replicates the structure and characteristics of the first training data set, but with augmented variations. This copying approach with statistical modeling allows comprehensive attack scenario simulation without requiring entirely new data collection processes.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system applies self-service by using the statistical distribution models derived from the first training data set to automatically generate the second training data set. The neural network training process itself produces the statistical parameters needed for data augmentation, eliminating the need for external intervention or manual attack scenario creation.

Inventive Principle:
Principle #25Self-service
