Structured vs. Unstructured Data Discovery

PII can reside in both structured (databases, CRM systems) and unstructured data (emails, documents). Each requires different approaches for discovery:

Leveraging Database Scanning Tools

When it comes to structured data, such as that found in databases and spreadsheets, identifying PII involves using specialized database scanning tools. These tools are designed to analyze the structure of tables, scrutinizing columns to detect and catalog PII.

Here’s a closer look at the approach:

Analyzing Table Structures

Database scanning tools work by examining the schema of databases. They identify tables and columns that are likely to contain PII by looking for common patterns and keywords associated with sensitive information. For example, columns labeled “Name,” “SSN,” “Email,” or “Phone Number” are flagged for further inspection.

Identifying PII Patterns

Advanced pattern recognition algorithms are employed to scan the content of these columns for PII. These algorithms can recognize specific data formats, such as social security numbers (XXX-XX-XXXX) or email addresses ([email protected]). This process ensures that even subtly labeled columns are not overlooked.

Enhancing Accuracy with Metadata and Regular Audits

Using Metadata

Metadata provides additional context about the data stored in databases. By leveraging metadata, organizations can gain insights into the origins, usage, and sensitivity of data. This information helps in fine-tuning the scanning tools to better identify PII. For instance, metadata can indicate when a particular column was last modified or who accessed it, providing clues about its sensitivity and relevance.

Conducting Regular Audits

Regular audits are essential to maintaining the accuracy and effectiveness of PII data discovery. These audits involve systematically reviewing and verifying the results of the scanning tools. They help in identifying any gaps or inaccuracies in the initial discovery process. By conducting periodic audits, organizations can ensure that their databases are continuously monitored for new or modified PII, maintaining compliance with data protection regulations.

Best Practices for Structured Data Discovery

• Automate Scanning: Implement automated scanning tools to ensure consistent and comprehensive coverage of all structured data sources.
• Integrate Metadata: Utilize metadata to enhance the precision of PII identification and to keep track of data usage and access patterns.
• Regularly Update Tools: Keep scanning tools up to date with the latest algorithms and patterns to detect new forms of PII.
• Perform Routine Audits: Schedule regular audits to verify the accuracy of PII detection and to identify any overlooked sensitive data.

Unstructured Data Discovery

NLP is a branch of artificial intelligence that enables computers to understand and interpret human language. For unstructured data discovery, NLP techniques can analyze text within documents and emails to identify PII. Here’s how it works:

• Text Parsing and Tokenization: NLP tools break down text into smaller units (tokens), such as words and phrases. This parsing helps in identifying relevant patterns and keywords that indicate the presence of PII.
• Contextual Analysis: NLP algorithms analyze the context in which certain keywords appear. For example, a sequence of numbers following the word “SSN” is likely a social security number. This contextual understanding enhances the accuracy of PII identification.
• Entity Recognition: NLP systems can recognize specific entities, such as names, dates, and addresses, within large text corpora. This capability allows for the precise extraction of PII from unstructured text.

Machine Learning (ML)

Machine learning involves training algorithms on large datasets to recognize patterns and make predictions. For unstructured data discovery, ML models can be trained to detect PII with high accuracy:

• Training Data: ML models are trained using labeled datasets that contain examples of PII and non-PII. This training enables the model to learn the distinguishing features of PII.
• Feature Extraction: During the training process, the model extracts features from the data, such as character patterns and context, which help in identifying PII.
• Predictive Analysis: Once trained, the ML model can analyze new data and predict the likelihood of certain information being PII. This predictive capability is particularly useful for processing large volumes of unstructured data.

Best Practices for Unstructured Data Discovery

Deploy Advanced AI Tools: Utilize NLP and ML tools specifically designed for PII discovery in unstructured data to enhance accuracy and efficiency.
