Backup Data Recovery Filtering for Privacy Compliance

The patent extracts specific data elements from backup data that are subject to privacy regulations (such as personally identifiable information) and isolates them in a separate secure storage location. This extraction allows the main backup data to remain intact for compliance purposes while the sensitive extracted elements are protected through secure deletion or isolation, thus resolving the contradiction between maintaining backup compliance and protecting data privacy.

The patent segments backup data into different categories based on sensitivity and regulatory requirements. By dividing the backup data storage into multiple segments or zones (e.g., sensitive data segment, non-sensitive data segment), the system can apply different protection mechanisms to each segment. This segmentation enables compliance with backup retention requirements for non-sensitive data while implementing enhanced privacy protections for sensitive data segments.

Instead of deleting entire backup datasets, the patent extracts only the specific sensitive data elements that require deletion under privacy regulations. This selective extraction and deletion approach maintains the integrity and completeness of the overall backup data while removing only the necessary sensitive portions, thus protecting both privacy and backup integrity.

The patent applies different quality standards and protection levels to different parts of the backup data based on their sensitivity. Rather than uniformly deleting or protecting all backup data, the system implements local quality control where sensitive data elements receive enhanced protection measures (such as secure deletion or encryption) while non-sensitive data maintains standard backup integrity, resolving the contradiction between privacy protection and backup integrity.

The patent implements automated mechanisms that enable the backup system to self-identify sensitive data elements using predefined classification rules and metadata. The system automatically tags, segments, and protects sensitive data without requiring manual intervention or complex external management processes. This self-service approach reduces operational complexity while maintaining robust privacy protection.

The patent creates a universal data classification and protection framework that can handle multiple types of sensitive data (personal information, financial data, health records, etc.) through a single integrated system. This multi-functional approach consolidates what would otherwise require multiple separate complex systems into one unified solution, reducing overall system complexity while providing comprehensive privacy protection across diverse data types.
