Dead Drop Network Data Exchange Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data exchange over the Internet is vulnerable to malicious actors, compromising user privacy and security, which discourages users from sharing sensitive information.
Innovation Solution
A dead drop network architecture that uses a decentralized domain to securely exchange data by generating unique identifiers and tokens for data storage and access, ensuring that only authorized parties can read or write data, while masking the intended recipients and data paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is exchanged over the Internet using conventional methods, then data transmission speed and ease of exchange are improved, but data security and privacy are compromised
Solution Approach 1:
The patent introduces dead drops as intermediary storage locations in a decentralized network. Data is written to dead drops by senders and read by recipients without direct peer-to-peer transmission. This intermediary mechanism breaks the traditional sender-recipient data path, preventing malicious actors from intercepting data during transmission while maintaining efficient data exchange through the distributed network infrastructure.
Solution Approach 2:
The patent segments data exchange into two independent operations: writing data to a dead drop and reading data from a dead drop. The sender only performs the write operation and receives a reference, while the recipient performs the read operation using that reference. This segmentation eliminates the need for continuous data transmission paths, thereby securing data against interception while preserving exchange efficiency through asynchronous operations.
2Ease of operation
If data is stored on remote servers for easy access, then data retrieval convenience is improved, but data privacy and control are worsened
Solution Approach 1:
The patent extracts the data storage function from centralized remote servers and distributes it across a decentralized network of dead drops. Each dead drop is an independent storage location controlled by its creator or designated recipient. This extraction removes data from centralized control points where privacy could be compromised, while maintaining easy access through the reference-based retrieval mechanism that works seamlessly across the distributed network.
Solution Approach 2:
The dead drop system enables self-service data storage and retrieval. Senders create dead drops and store data autonomously, receiving automated references for later retrieval. Recipients can access their designated dead drops independently using provided references. This self-service model eliminates the need for centralized server management while preserving convenient data access, with each participant maintaining control over their own data lifecycle.
Data Source
AI summary
A sender uses a double-write protocol to pass data to a recipient using a dead drop network architecture. The sender sends, to a dead drop domain, a data payload to store at the dead drop domain, and receives payload access information corresponding to a payload dead drop where the payload data is stored. The sender sends, to the dead drop domain, one or more instances of metadata including the payload access information to store at the dead drop domain, and receives metadata access information corresponding to one or more metadata dead drops where the metadata is stored. The sender provides the metadata access information to one or more recipients. A recipient uses the metadata access information to read the corresponding metadata dead drop. The recipient then uses the payload access information from the metadata to read the payload dead drop and receive the payload data.
