Web Traversal Data Engine

Browser Cash's Web Traversal Data Engine enables privacy-preserving collection, processing, and utilization of web interaction patterns across the distributed node network, creating a continuously updating dataset for AI training.

System Architecture

The Traversal Data Engine implements a multi-layered approach to data collection and processing:

Element Identification and Interaction Significance

Semantic Element Classification

The system employs advanced techniques to identify and classify meaningful web elements:

interface ElementClassifier {
  selectors: Map<ElementRole, SelectorStrategy[]>;
  neuralClassifier: NeuralNetworkModel;
  heuristicEngine: HeuristicRules;
  historicalPerformance: PerformanceMetrics;
}

enum ElementRole {
  NAVIGATION,
  ACTION_BUTTON,
  FORM_INPUT,
  CONSENT_DIALOG,
  AUTHENTICATION,
  CONTENT_CONTAINER,
  ADVERTISEMENT,
  PAYWALL,
  CAPTCHA,
  INTERACTIVE_MEDIA
}

The element classification process:

Visual Analysis
- Bounding box detection
- Element rendering characteristics
- Visual prominence calculation

Interaction Value Assessment

Each captured interaction is evaluated for its significance:

interface InteractionValueMetrics {
  taskCompletion: number;       // 0.0-1.0
  informationGain: number;      // 0.0-1.0
  interactionEfficiency: number; // 0.0-1.0
  pathNovelty: number;          // 0.0-1.0
  outcomeSuccess: number;       // 0.0-1.0
}

class ValueAssessmentEngine {
  evaluateInteraction(event: InteractionEvent, context: SessionContext): InteractionValueMetrics;
  updateModelWeights(feedback: ValueFeedback): void;
  identifyHighValuePatterns(interactions: InteractionEvent[]): InteractionPattern[];
}

The system calculates interaction value through:

Task completion correlation

  extractedAssets: Map<string, ArrayBuffer>;
}

enum ChallengeType {
  IMAGE_SELECTION,
  TEXT_BASED,
  SLIDER,
  PUZZLE,
  BEHAVIORAL,
  INVISIBLE,
  HONEYPOT,
  TIMING_BASED
}

The CAPTCHA analysis pipeline:

}

This enables:

Intelligent Pattern Transfer

Cross-Domain Knowledge Application

The system enables the transfer of interaction patterns across similar websites:

interface DomainSimilarity {

  protectionSimilarity: number;
}

class CrossDomainMapper {
  calculateSimilarity(domain1: string, domain2: string): DomainSimilarity;
  mapElements(sourceElements: ElementMap, targetDomain: string): ElementMap;
  transferInteractionSequence(sequence: InteractionSequence, targetDomain: string): AdaptedSequence;
  evaluateTransferSuccess(originalSuccess: SuccessMetrics, transferSuccess: SuccessMetrics): TransferEffectiveness;
}

The pattern transfer process involves:

Structure Mapping
- DOM hierarchy comparison
- Visual layout similarity analysis
- Content organization patterns
Interaction Translation
- Element purpose matching

Dynamic Dataset Construction

Feature Engineering Pipeline

The system transforms raw interaction data into structured training features:

interface FeatureVector {
  interactionSequence: number[];
  elementProperties: Map<string, number[]>;
  temporalDynamics: number[];
  contextualFeatures: number[];
  outcomeIndicators: number[];
}

class FeatureExtractionPipeline {
  extractSessionFeatures(session: BrowsingSession): FeatureVector[];
  extractElementFeatures(element: WebElement): number[];

  selectFeatures(features: number[], importance: number[]): number[];
}

Key feature engineering techniques:

interface DatasetOptimization {
  deduplication: DeduplicationStrategy;
  balancing: ClassBalancingStrategy;

}

The optimization process includes:

Privacy-Preserving Analytics

Federated Learning Implementation

The system employs federated learning to improve models without centralizing sensitive data:

interface FederatedLearningConfig {
  localEpochs: number;
  minClientsPerRound: number;
  aggregationStrategy: AggregationStrategy;
  diffPrivacyBudget: number;
  gradientCompression: CompressionLevel;
  secureCommunication: SecureChannelConfig;
}

class FederatedModelTrainer {

}

Security measures within the federated learning system:
