## Government Use Cases

### 1. Citizen Services

#### Government Chat Applications

```rust
use llm_security::{SecurityEngine, SecurityConfig, GovernmentSecurity};

// Configure government security
let government_security = GovernmentSecurity::new()
    .with_citizen_data_protection(true)
    .with_government_information_protection(true)
    .with_classification_protection(true)
    .with_privacy_protection(true)
    .with_audit_logging(true);

let config = SecurityConfig::new()
    .with_prompt_injection_detection(true)
    .with_jailbreak_detection(true)
    .with_unicode_attack_detection(true)
    .with_output_validation(true)
    .with_sensitive_information_detection(true)
    .with_citizen_data_detection(true)
    .with_government_information_detection(true)
    .with_classification_detection(true);

let engine = SecurityEngine::with_config(config)
    .with_government_security(government_security);

// Process government citizen service
async fn process_government_citizen_service(message: &str, citizen_id: &str) -> Result<String, SecurityError> {
    // Analyze input for threats
    let analysis = engine.analyze_input(message).await?;

        return Err(SecurityError::ThreatDetected("Security threat detected in government citizen service"));
    }
    
    // Process message safely
    let response = process_government_message(message).await?;
    
    // Validate output for government information protection
    let validation = engine.validate_output(&response).await?;
    
    if !validation.is_valid() {
        // Log government information violation
        log_government_information_violation(citizen_id, &validation.issues());
        return Err(SecurityError::GovernmentInformationViolation("Output contains unprotected government information"));
    }
    
    Ok(response)
}
```

#### Public Information Security

```rust
use llm_security::{SecurityEngine, SecurityConfig, PublicInformationSecurity};

// Configure public information security
let public_information_security = PublicInformationSecurity::new()
    .with_public_data_protection(true)

let config = SecurityConfig::new()
    .with_prompt_injection_detection(true)
    .with_jailbreak_detection(true)
    .with_unicode_attack_detection(true)
    .with_output_validation(true)
    .with_sensitive_information_detection(true)
    .with_public_data_detection(true)
    .with_government_information_detection(true)
    .with_classification_detection(true);

let engine = SecurityEngine::with_config(config)
    .with_public_information_security(public_information_security);

// Process public information
async fn process_public_information(information: &str, citizen_id: &str) -> Result<String, SecurityError> {
    // Analyze input for threats
    let analysis = engine.analyze_input(information).await?;
    
    if !analysis.is_secure() {
        // Log security incident
        log_security_incident(citizen_id, &analysis.threats());
        return Err(SecurityError::ThreatDetected("Security threat detected in public information"));
    }
    
    // Process information safely
    let response = process_public_information_safely(information).await?;
    
    // Validate output for public information protection
    let validation = engine.validate_output(&response).await?;
    
    if !validation.is_valid() {
        // Log public information violation
        log_public_information_violation(citizen_id, &validation.issues());
        return Err(SecurityError::PublicInformationViolation("Output contains unprotected public information"));
    }
    
    Ok(response)
