Solution Overview

Problem

Cloud information storage systems face challenges in efficiently detecting personally identifiable information (PII) across various file types without exposing the actual data, especially when dealing with structured and unstructured data files, which complicates compliance with legal regulations and data security requirements.

Innovation Solution

A PII detection system that includes preprocessing components to identify file types, scanning components for sampling and data standardization, and machine-learned models to analyze structured data efficiently, reducing resource usage and maintaining data security by processing only sampled and standardized data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the system processes all data files to detect PII, then detection accuracy is improved, but resource consumption and processing time increase significantly

Engineering Contradiction:
ImprovePII detection accuracyVSAvoidprocessing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent applies partial action by processing only a sample subset of files rather than the entire dataset. The system selects a representative sample of files from the cloud storage system and processes only those samples through the PII detection pipeline, achieving acceptable detection accuracy while dramatically reducing processing time and computational resources compared to exhaustive processing of all files.

Inventive Principle:
Principle #16Partial or excessive action

2Measurement precision

If the system processes all data files to detect PII, then detection accuracy is improved, but resource consumption increases

Engineering Contradiction:
ImprovePII detection accuracyVSAvoidcomputational resource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system processes only a sampled subset of files rather than the complete dataset, reducing computational resource consumption and energy usage while maintaining acceptable detection accuracy. This partial processing approach avoids the excessive resource demands of analyzing every file in the cloud storage system.

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If the system exposes actual PII data for analysis, then detection accuracy is improved, but data security and compliance are compromised

Engineering Contradiction:
ImprovePII detection accuracyVSAvoiddata security risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent creates and processes copies of PII data rather than exposing the actual original data. The system generates synthetic PII data that mimics the structure and characteristics of real PII for training and testing purposes, and processes sampled copies during detection operations. This copying approach enables accurate detection model development and operation while maintaining data security and compliance by never exposing the actual sensitive PII stored in the cloud system.

Inventive Principle:
Principle #26Copying

4Adaptability or versatility

If the system processes diverse file types uniformly, then versatility is improved, but processing efficiency decreases

Engineering Contradiction:
Improvefile type compatibilityVSAvoidprocessing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the diverse file types into distinct categories (structured files, semi-structured files, unstructured files) and applies specialized processing methods tailored to each category. The system identifies the file type and routes it to the appropriate processing pipeline, enabling efficient handling of each file format while maintaining versatility across multiple file types. This segmentation avoids the inefficiency of applying a single uniform processing approach to all file types.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and techniques are disclosed for determining personally identifiable information in one or data file. An input data file is analyzed to determine whether it includes structured data based on an explicit indicator and/or header content. If it includes structured data, the data in the file is sampled and standardized for input to a machine-learned personally identifiable information that provide personally identifiable information detection results indicating quantities and types of personally identifiable information detected. The results are used with the input file to determine aggregated personally identifiable information results that may be presented to a user without exposing any personally identifiable information.
