Intelligent Content Ghosting for Mobile Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mobile Content Management (MCM) tools impose productivity limitations by applying restrictive security policies to entire files, even if only a small part is sensitive, due to the susceptibility of mobile devices to theft, loss, or unsecure connections, which can hinder access to necessary business content.
Innovation Solution
Implementing a method that 'ghosts' sensitive portions of content items based on defined security policies, including environmental factors like time, location, and communication type, allowing access to non-sensitive parts while protecting sensitive information, and dynamically adjusting access as environmental conditions change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If restrictive security policies are applied to entire files, then security of sensitive information is improved, but user productivity deteriorates
Solution Approach 1:
The patent segments the content item into sensitive and non-sensitive portions, applying security policies only to the sensitive segments. This allows users to access and work with non-sensitive portions freely while maintaining security controls over sensitive information, thereby resolving the contradiction between security and productivity.
Solution Approach 2:
The patent applies different security attributes to different portions of the same content item. Sensitive portions are protected with security restrictions while non-sensitive portions are accessible without restrictions, enabling localized security enforcement that maintains both security and user productivity.
2Reliability
If security restrictions are applied to content, then protection of sensitive data is improved, but ease of operation deteriorates
Solution Approach 1:
By segmenting content into sensitive and non-sensitive portions, the system allows users to freely access and operate with non-sensitive content while automatically applying security controls to sensitive portions, thereby maintaining ease of operation for the majority of content while protecting sensitive data.
Solution Approach 2:
The system automatically identifies and applies security policies to sensitive portions without requiring user intervention or manual classification, making the security process transparent and effortless for users while maintaining strong protection for sensitive information.
3Reliability
If environmental factors are monitored for security policies, then security enforcement is improved, but device complexity increases
Solution Approach 1:
The mobile device automatically monitors its own environmental factors (location, time, network connection) and applies security policies based on pre-defined conditions without requiring complex external management systems, thereby improving security enforcement while minimizing additional device complexity.
Solution Approach 2:
The security policy enforcement dynamically adapts to changing environmental conditions, automatically adjusting access rights based on factors like location, time of day, and network security, allowing flexible security enforcement without requiring manual reconfiguration or complex static security architectures.

AI summary
A method includes performing operations as follows on a processor: receiving a request for a content item from a mobile device, determining that the content item is protected by a security policy, the security policy comprising an environmental factor associated with the use of the mobile device, ghosting a portion of the content item based on the security policy, and sending the content item and the security policy to the mobile device.
