Buffering System for Secure Personal Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In open environments, there is a risk of unauthorized access to personal data when users interact with multiple computer terminals, as existing solutions do not adequately protect data privacy during data transfer between devices.
Innovation Solution
A buffering system is introduced to act between source and target computing devices, ensuring only a single persisted copy of personal data exists on the target device being used, with login credentials generated to lock and unlock the data, preventing access from other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personal data is centrally stored and accessible via pre-defined connections on multiple terminals, then data accessibility and continuity are improved, but data security and privacy protection deteriorate due to unauthorized access risks
Solution Approach 1:
A buffer system is introduced as an intermediary component between source and target computing devices. The buffer receives personal data from the source device, stores it temporarily, and transfers it to the target device. This intermediary mechanism enables data continuity across terminals while preventing unauthorized access, as the buffer controls and monitors all data transfer operations.
Solution Approach 2:
The system segments the data storage and access control functions across multiple components: the source computing device, the buffer system, and the target computing device. By dividing the system into these separate segments, each with specific responsibilities, the patent achieves both data accessibility (through the buffer's transfer capability) and security (through distributed control and temporary storage).
2Reliability
If multiple persisted copies of personal data are maintained across different computing devices, then data availability is improved, but data protection deteriorates due to increased attack surfaces
Solution Approach 1:
The buffer system acts as a controlled intermediary that manages data copies. Instead of allowing multiple independent persisted copies across devices, the buffer receives data from the source, maintains control during transfer, and delivers it to the target. This ensures data availability through the transfer mechanism while minimizing protection vulnerabilities by centralizing control in the buffer.
Solution Approach 2:
The system implements a mechanism where data copies are discarded from the source device after successful transfer to the buffer, and from the buffer after successful transfer to the target device. This temporary storage and systematic discarding approach maintains data availability during the transfer process while reducing the number of persisted copies that could be vulnerable to attacks.
3Ease of operation
If data is transmitted between multiple terminals in open environments, then user convenience is improved, but security risks increase due to potential unauthorized access at each terminal
Solution Approach 1:
The buffer system serves as a secure intermediary that handles data transmission between terminals. Users can conveniently access their personal data across multiple terminals through the buffer's transfer capability, while the buffer itself provides security by controlling the transmission process and preventing unauthorized access at intermediate terminals.
Solution Approach 2:
The buffer system implements temporary, short-lived data storage that is discarded after use. Data exists in the buffer only during the transfer process and is systematically removed afterward, creating a disposable storage mechanism that maintains user convenience while minimizing security risks associated with persistent storage at multiple locations.

AI summary
Systems (100) and computer-implemented methods for personal data transmission from a source computing device (110) to a target computing device (120) with improved data protection, wherein the source device (110) receives the personal data including one or more digital representations (1a, 2a, 3a) of one or more physical items wherein the physical items (1, 2, 3) belong to an item selection of a particular individual (10). The source device (110) generates a local data structure (111) and stores the one or more digital representations in the local data structure. Upon receipt of a transmission request a copy of the local data structure is sent to a buffer system (130) and the local data structure is deleted from the source computing device. The target computing device (121) receives login credentials from a user to access the target computing device wherein the login credentials include a secret associated with the local data structure (111). The user is authenticated to grant access to the target computing device based on the received login credentials. The target computing device sends a retrieval request to the buffer system wherein the retrieval request is generated based on the login credentials to request the retrieval of the buffered data structure. In response to the retrieval request the target computing device receives a copy of the buffered data structure and grants access to the received data structure for the authenticated user wherein the received data structure remains the only persisted copy of the data structure.
