DLP Server Email Data Transfer Timeout Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in managing the transfer of sensitive information to mobile devices, where existing solutions face complexity and cost issues due to the variety of mobile device configurations, and there is a risk of data loss if sensitive information is not properly protected, leading to legal liabilities and reputational damage.
Innovation Solution
A method and apparatus that filter data sets based on mobile device properties, such as model number, operating system, and secure channel status, to prevent sensitive data loss by sending filtered responses in portions to avoid timeouts and ensure secure data transfer, using a DLP server operating in a reverse proxy configuration to intercept and manage email data before it reaches the mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DLP software is deployed on each mobile device to protect sensitive data, then data security is improved, but device complexity and implementation cost increase significantly
Solution Approach 1:
The patent introduces a server-side intermediary system that acts as a mediator between email servers and mobile devices. This server filters and secures email data before transmission, eliminating the need for complex DLP software on each mobile device while maintaining data security. The intermediary handles sensitive data processing centrally, reducing device-level complexity.
2Reliability
If email data is filtered and processed before sending to mobile devices, then data protection is improved, but data transfer time increases
Solution Approach 1:
The system performs preliminary filtering and security processing of email data on the server side before transmission to mobile devices. By pre-processing data and identifying sensitive content in advance, the system avoids time-consuming filtering operations on mobile devices, thereby reducing overall data transfer time while maintaining protection.
Solution Approach 2:
The patent replaces mechanical client-side filtering mechanisms with server-side processing. This substitution allows for more efficient data handling using centralized resources, reducing the time burden on individual mobile devices and improving overall transfer efficiency while maintaining data protection standards.
3Productivity
If sensitive information is transferred to mobile devices for business use, then productivity is improved, but risk of data loss increases
Solution Approach 1:
The patent converts the potential harm of mobile device data loss into a benefit by implementing server-side filtering that identifies and protects sensitive information. The system uses the mobile device's connectivity advantage for productivity while neutralizing the data loss risk through automated server-side security measures, effectively transforming the vulnerability into a controlled security enhancement.

AI summary
Methods and apparatus provide for network communication to be maintained during transfer of email data between two devices. In one aspect a method includes receiving a request via a network connection with a mobile device for email data, determining a network timeout value of the request from the mobile device, producing the email data in response to receiving the request, in parallel with the production of the email data and while the processing of the email data is incomplete, determining an interval less than the network timeout value of the request, and sending a portion of a response to the request over the network connection to the mobile device at the interval, completing the response to the mobile device over the network connection in response to completion of the production of the email data.
