Sender-Controlled Data Deletion in Mobile Communication Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data deletion systems lack sender control over data existence and access after data is sent, leaving data at the mercy of the receiver's device and network policies, leading to potential information leakage and loss of control for the sender.
Innovation Solution
A method allowing senders to control data access and deletion within a communication network by initiating a delete command or setting a data time of existence from their mobile device, ensuring they can delete data even after it has been received by the receiver and remains within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transmitted to a receiver through a communication network, then the receiver can access and use the data, but the sender loses control and knowledge of the data's existence and location
Solution Approach 1:
The patent implements a feedback mechanism where the receiver's device sends acknowledgments and status updates back to the sender's device about data delivery and storage status. This allows the sender to maintain knowledge of data existence and location without interfering with the receiver's access rights, resolving the contradiction between ease of data access and loss of sender control.
Solution Approach 2:
The communication network acts as an intermediary that maintains metadata about transmitted data, including storage locations and delivery status. This intermediary layer enables the sender to query data status without directly accessing the data itself, preserving sender control while allowing receiver access through the network mediator.
2Reliability
If the receiver stores data locally on their device, then data access is fast and reliable, but the sender cannot delete or control the data after transmission
Solution Approach 1:
The patent makes the data lifecycle dynamic by implementing remote delete commands that allow the sender to change data persistence status after transmission. The system transitions from static local storage to dynamic controllable storage, where data can be retained or deleted based on sender's changing needs, while maintaining reliable local access during the retention period.
Solution Approach 2:
The sender can pre-configure deletion policies and time limits for transmitted data before actual transmission occurs. This preliminary action allows the sender to establish control parameters in advance, enabling flexible data lifecycle management while ensuring reliable delivery and storage during the predetermined retention period.
3Ease of manufacture
If existing deletion systems are used, then short message services data can be deleted, but binary or ascii file data cannot be deleted from remote devices or network storage
Solution Approach 1:
The patent creates a universal deletion system that handles multiple data types (SMS, binary files, ASCII files) through a common protocol and interface. The delete command structure and communication mechanism are designed to be data-type-agnostic, allowing the same system to delete various formats of transmitted data from both network storage and remote device storage, significantly increasing adaptability.
4Adaptability or versatility
If data remains in the communication network after transmission, then it can be accessed and forwarded, but information leakage risk increases
Solution Approach 1:
The patent implements periodic data lifecycle management where data automatically expires or can be remotely deleted after a predetermined time period or number of access events. This periodic cleanup mechanism reduces information leakage risk by limiting the duration data remains accessible in the network, while still allowing legitimate forwarding and access during the authorized retention period.
Data Source
AI summary
A method and system are provided for remotely deleting data stored on the remote mobile communication device, and within the communication network, by initiating a delete command, or setting data time of existence when creating the data, from a sender mobile communication device.
