Data Leakage Detection via Traffic Clustering and Deduplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data leakage detection systems face challenges in scalability, privacy preservation, accuracy, and timeliness, particularly in handling large volumes of data and distinguishing between intentional and accidental data leaks, with no existing tools effectively addressing accidental leaks caused by improper data retrieval criteria.
Innovation Solution
A system that intercepts web traffic data, de-duplicates, and clusters it to reduce processing load, applies predefined rules to identify unauthorized data transmission, uses a Kafka framework for real-time processing, and employs supervised learning to classify false alarms, thereby enhancing detection accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data leakage detection systems process large volumes of web traffic data in real-time, then timeliness of detection is improved, but system scalability and processing capacity deteriorate due to network and memory bottlenecks
Solution Approach 1:
The system performs de-duplication of web traffic data before full processing, removing duplicate copies of repeating data in advance. This preliminary action reduces the volume of data that needs to be transmitted and processed, allowing real-time detection without overwhelming system resources
Solution Approach 2:
The system segments web traffic data into clusters based on de-duplication, organizing data into manageable groups. This segmentation reduces the processing burden on individual system components while maintaining comprehensive detection coverage across all data streams
2Measurement precision
If the system processes and analyzes all web traffic data to ensure accurate leakage detection, then detection accuracy is improved, but false positive rates increase and privacy preservation deteriorates
Solution Approach 1:
The system pre-stores allow tables containing predefined data types and associated users before processing web traffic data. This preliminary preparation enables the system to compare incoming data against established criteria, improving detection accuracy while preserving privacy by only flagging deviations from predefined patterns
Solution Approach 2:
The system applies selective processing by comparing data elements against pre-defined allow tables rather than analyzing all data in detail. This partial action approach maintains detection accuracy for unauthorized transmissions while reducing false positives and preserving privacy for legitimate data access patterns
3Quantity of substance
If the system transmits and processes large amounts of web traffic data, then detection coverage is improved, but network bandwidth consumption and memory usage increase
Solution Approach 1:
The system performs de-duplication of web traffic data before transmission and processing, removing duplicate copies of repeating data in advance. This preliminary reduction significantly decreases the volume of data transmitted over the network and processed in memory, reducing resource consumption while maintaining comprehensive detection coverage
Solution Approach 2:
The system clusters de-duplicated data into organized groups, reducing the overall data volume that requires active processing. This segmentation allows the system to handle large quantities of unique data efficiently by processing clustered representations rather than individual data elements
Data Source
AI summary
A system for detecting data leakage is disclosed. The system intercepts web traffic data, de-duplicates the web traffic data, and extracts data elements from the web traffic data. The system further groups the data elements into multiple clusters based on data types associated with the data elements. The system then identifies data elements in a cluster that were previously sent to a user and identifies allowed data elements from an allow table that are supposed to be sent to the user. The system determines whether there is a data leakage by determining whether the identified data elements in the cluster comprises at least one data element that is not in the identified allowed data elements in the allow table.
