OSI Layer 1 Parsing Function for Sensitive Data Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security protocols for data transmission, such as encryption, are not foolproof and can be breached with sufficient time and effort, and sensitive data is often transmitted insecurely through channels like email, which lacks encryption.
Innovation Solution
A method and system that utilize a parsing function at the OSI Layer 1 or Layer 3 to scan for sensitive data using a list of 'hot' words, warning users and optionally preventing transmission without authorization, and employing a processor to manage data creation, storage, and transmission across a computer network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption techniques are used to protect sensitive data, then security is improved, but the system becomes vulnerable to determined attackers with sufficient time and resources
Solution Approach 1:
The system performs preliminary scanning of documents before transmission to detect sensitive data. The parsing function analyzes documents at OSI Layer 1 or Layer 3 to identify sensitive information patterns, and the system proactively prevents transmission before the data can be compromised, rather than relying solely on post-breach encryption responses
Solution Approach 2:
The patent introduces an intermediary monitoring system that sits between the document creation application and the transmission channel. This intermediary parsing function intercepts documents, scans for sensitive data using pattern matching, and controls transmission based on detection results, acting as a mediator that adds security without requiring end-users to manage complex encryption protocols
2Ease of operation
If sensitive data is transmitted through email for ease of use, then ease of operation is improved, but security is compromised due to lack of encryption
Solution Approach 1:
The system provides self-service security by automatically scanning documents for sensitive data without requiring user intervention. The parsing function autonomously detects sensitive information patterns, determines transmission safety, and controls the transmission process, allowing users to maintain simple email operations while the system handles security automatically in the background
3Reliability
If monitoring is implemented to reduce sensitive data transmittal, then security is improved, but the system complexity increases
Solution Approach 1:
The monitoring system is segmented into distinct functional components: a parsing function for pattern matching, a detection module for identifying sensitive data, and a control module for managing transmission. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and reducing complexity through modular design
Data Source
AI summary
An apparatus, a method, and a computer program are provided for securing transmitted text. Once text has been produced by an application, the potential exists for an unintended third party to obtain sensitive data transmitted over computer networks. However, a parsing function can then operate either on an individual computer or on a network to scan text at an Open Systems Interconnection (OSI) Layer 1 to assist in the prevention of sensitive data transmission. By utilizing the parsing function, text can be scanned for potentially sensitive data by using a variety of techniques, such as a learning algorithm. The sensitive data can then be verified by a user, bypassed, or autostripped.
