Wireless SMS Module with Dual Storage and Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Short Message Service (SMS) technologies do not log or store messages, lack encryption for security, and restrict sending messages to multiple recipients simultaneously, making them unsuitable for corporate communication needs.
Innovation Solution
A wireless device with an enhanced SMS module that logs and encrypts messages, allowing simultaneous sending to multiple recipients by storing messages locally and remotely, and using encryption protocols like TripleDES and Base64 encoding to ensure security and compatibility across wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SMS messages are not logged or stored, then device storage is preserved and system simplicity is maintained, but corporate audit requirements cannot be met and message tracking is impossible
Solution Approach 1:
The patent divides the storage system into two separate components: local storage on the wireless device and remote storage on the wireless carrier's server. This segmentation allows the device to maintain simplicity while meeting audit requirements through remote logging, resolving the contradiction between audit compliance and device complexity.
2Reliability
If SMS messages are not encrypted, then processing speed is maintained and system complexity is reduced, but security requirements for sensitive information cannot be met
Solution Approach 1:
The patent implements encryption as a preliminary action by encrypting messages at the source device before transmission and decrypting them at the destination. This approach ensures security is built into the system from the outset without requiring complex real-time encryption processing, thus meeting security requirements while maintaining reasonable system complexity.
3Productivity
If SMS messages can only be sent to one recipient at a time, then message routing is simplified and system complexity is reduced, but productivity for sending to multiple recipients is severely limited
Solution Approach 1:
The patent merges multiple individual message transmissions into a single group message transmission by storing the message on the wireless carrier's server and enabling multiple recipients to retrieve it simultaneously. This combining approach dramatically improves productivity for sending to multiple recipients while keeping the routing system relatively simple through server-based management.
4Productivity
If the same SMS message must be manually entered multiple times for multiple recipients, then message uniqueness is ensured, but time consumption and operational efficiency are severely reduced
Solution Approach 1:
The patent implements a copying mechanism where the original message is stored on the wireless carrier's server and multiple recipients receive copies of this single stored message. This eliminates the need for manual re-entry while ensuring message consistency, thereby dramatically improving productivity and eliminating time loss associated with manual duplication.
Data Source
AI summary
A wireless device for processing an SMS message stores the message on a local first storage device, and sends the message to a wireless carrier SMS facility. The device further stores the message from the first storage device on a second storage device that is remote from the wireless device.
