# Introduction
Handling sensitive data is fraught with risks, from accidental exposure to intentional breaches. Regulatory standards such as **GDPR** and **HIPAA** mandate that organizations anonymize or pseudonymize sensitive information during processing, storage, and logging. The **DataPrivacyManager** class is designed to simplify these operations by automatically anonymizing sensitive fields and logging them in a privacy-compliant manner.

This module provides:
* **Strong anonymization** using SHA-256 hashing.
* **Automated workflows** for managing sensitive data responsibly.
* **Customizability** to fit specific organizational privacy and security requirements.
* **Anonymize sensitive fields** using irreversible hashing.
* **Log data privacy-compliantly**, anonymizing sensitive info before logging.
* **Secure sensitive workflows** to meet GDPR, HIPAA, and related standards.

The **ai_data_privacy_manager.html** file includes:
* Visual tutorials
* Example use cases
* Compliance workflow simulations

Use this module to handle PII responsibly while maintaining transparency and privacy-compliant logging.

* Automatically anonymizes sensitive fields before securely logging data records.

* **Customizable Anonymization Fields:**
* Users can specify which fields in a dataset should be anonymized.

* **Error Handling and Logging:**
* Tracks errors during anonymization or logging operations to ensure robust workflows.

* **Integration-Friendly Design:**
* Can be seamlessly integrated into ETL workflows, APIs, or other data pipelines.

# How It Works

The **DataPrivacyManager** class provides two key methods:
* **Anonymization:** Anonymizes the sensitive fields in records passed to the system using cryptographic hashing.
* **Privacy-Compliant Logging:** Logs anonymized records for secure storage and compliance with regulatory standards.

## 1. Anonymization
The **anonymize** method applies **SHA-256 hashing** to specific sensitive fields (e.g., **"email"**, **"phone_number"**) in the provided data.

**Workflow:**
* Identify fields to anonymize based on the user's configuration (**anonymization_fields**).
* Compute the SHA-256 hash of the field values for irreversible anonymization.
* Replace sensitive values in the original dictionary with their hashes while keeping other fields intact.

**Example Output:**
```
plaintext
Input Data: {'name': 'Alice', 'email': 'alice@example.com'}
Anonymized Data: {'name': 'Alice', 'email': 'f1d2d2f924e986ac86fdf7b36c94bcdf32beec15'}
```
----

## 2. Privacy-Compliant Logging
The **log_with_compliance** method logs anonymized datasets instead of raw fields to protect sensitive information.

**Workflow:**
* Call the **anonymize** method to sanitize sensitive fields.
* Log the anonymized record via the `logging` library.
* Catch and log any exceptions encountered during processing.

Example Log Output:

```
plaintext
INFO:root:Compliant log: {'name': 'Alice', 'email': 'f1d2d2f924e986ac86fdf7b36c94bcdf32beec15'}
```

----

## 3. Logging and Error Handling
The module uses Python's **logging** module to ensure traceability and robustness:
* **Info Logs:** Capture anonymized records for audits or debugging.
* **Error Logs:** Track failures in anonymization or logging operations for troubleshooting.

Example Error Log:
```
plaintext
ERROR:root:Failed to log data with compliance: Invalid field value encountered.
```

----

# Dependencies

The module requires the following:

## Required Libraries
* **hashlib:** Standard Python library for cryptographic hashing (SHA-256).

# Usage

Below are examples showcasing basic and advanced usage of **DataPrivacyManager**.

## Basic Examples
**Anonymizing sensitive fields and logging records:**

```
python
from ai_data_privacy_manager import DataPrivacyManager
```
# **Initialize the privacy manager with fields to anonymize**
```
data_privacy_manager = DataPrivacyManager(anonymization_fields=["email", "phone_number"])
```
# **Input dataset**
```
user_data = {
    "name": "Alice",
    "email": "alice@example.com",
    "phone_number": "1234567890"
}
```
# **Log anonymized data**
```
data_privacy_manager.log_with_compliance(user_data)
```

**Example Log Output:**
```
plaintext
INFO:root:Compliant log: {'name': 'Alice', 'email': 'cd192d68db7f5b0a6...', 'phone_number': 'fa246d0262c...'}
```

## Advanced Examples

### 1. Custom Hashing Algorithms
Extend the **DataPrivacyManager** class to use a different hashing mechanism, such as MD5 or SHA-512.

```
python
class CustomHashPrivacyManager(DataPrivacyManager):
    def anonymize(self, record):
        anonymized_record = {}
        for key, value in record.items():
            if key in self.anonymization_fields:
                anonymized_record[key] = hashlib.md5(value.encode()).hexdigest()
            else:
                anonymized_record[key] = value
        return anonymized_record
```
# **Usage Example**
```
custom_manager = CustomHashPrivacyManager(anonymization_fields=["email"])
print(custom_manager.anonymize({"email": "user@example.com"}))
```

**Output:**
```
plaintext
{'email': 'b58996c504c5638798eb6b511e6f49af'}
```

---

### 2. Selective Anonymization Based on Conditions
Anonymize fields conditionally, for example, only anonymize emails matching certain domains.

```
python
class ConditionalPrivacyManager(DataPrivacyManager):
    def anonymize(self, record):
        anonymized_record = {}
        for key, value in record.items():
            if key in self.anonymization_fields and value.endswith("@example.com"):
                anonymized_record[key] = hashlib.sha256(value.encode()).hexdigest()
            else:
                anonymized_record[key] = value
        return anonymized_record
```
# **Usage Example**
```
conditional_manager = ConditionalPrivacyManager(anonymization_fields=["email"])
print(conditional_manager.anonymize({"email": "test@example.com", "name": "Bob"}))
```

---

### 3. Integration With ETL Workflows
Integrate **DataPrivacyManager** into an ETL data pipeline to anonymize sensitive rows before transformation.

```
python
class ETLPipeline:
    def __init__(self, privacy_manager):
        self.privacy_manager = privacy_manager

    def process(self, data):
        anonymized_data = [self.privacy_manager.anonymize(record) for record in data]
        return anonymized_data
```
# **Initialize Privacy Manager**
```
privacy_manager = DataPrivacyManager(anonymization_fields=["email", "phone_number"])
```
# **Pipeline Example**
```
pipeline = ETLPipeline(privacy_manager=privacy_manager)
data = [
    {"name": "Alice", "email": "alice@example.com", "phone_number": "1234"},
    {"name": "Bob", "email": "bob@example.com", "phone_number": "5678"}
]
anonymized_data = pipeline.process(data)
print(anonymized_data)
```

**Output:**
```
plaintext
[
    {'name': 'Alice', 'email': '...', 'phone_number': '...'},
    {'name': 'Bob', 'email': '...', 'phone_number': '...'}
]
```
