Secure Data Sharing via Host Server Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks, such as email and web folders, lack the necessary security and scalability for sharing confidential information, as they are vulnerable to eavesdropping and unauthorized access, especially when dealing with multiple users and large datasets.
Innovation Solution
A secure data sharing system that employs encryption and decryption keys managed by a host server, using public key cryptography to ensure only authorized users can access conversations, with the server maintaining encrypted data and not the decryption information to prevent breaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If E-mail system is used for data sharing, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The patent segments the data sharing process into distinct phases: data encryption by the sender, secure transmission through the server, and decryption by the receiver. The server only handles encrypted data, separating the security function from the data storage function. This segmentation allows the system to maintain ease of operation like email while achieving security through cryptographic protocols.
Solution Approach 2:
The patent introduces a secure communication server as an intermediary between senders and receivers. The server acts as a trusted mediator that facilitates data transmission without storing decryption keys or having access to unencrypted data. This intermediary approach enables secure data sharing while maintaining the simplicity of email-like operation.
2Adaptability or versatility
If web folder service is used for data sharing, then scalability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a universal data sharing platform that can handle multiple types of data (documents, images, videos) and support multiple users simultaneously through a single interface. The server provides standardized encryption and decryption functions that work for all users, achieving scalability without requiring users to perform manual encryption operations.
Solution Approach 2:
The patent enables users to perform self-service by automatically handling encryption and decryption operations through the server. Users simply upload data and provide recipient information, while the server automatically encrypts the data, transmits it securely, and makes it accessible to the intended recipient without requiring manual cryptographic operations.
3Quantity of substance
If web folder service is used for data sharing, then data storage capability is improved, but security deteriorates
Solution Approach 1:
The patent segments security responsibilities by implementing encryption at the sender's end before data reaches the server. The server stores only encrypted data and does not possess the decryption keys, separating the data storage function from the security function. This allows large amounts of data to be stored while maintaining security, as even the server cannot access unencrypted data.
Solution Approach 2:
The patent applies beforehand cushioning by encrypting data before it is stored on the server. The encryption keys are managed separately and securely, creating a protective layer that prevents even the server from accessing plaintext data. This prior encryption cushioning ensures that if the server is compromised or if keys are leaked, the data remains protected.

AI summary
This disclosure relates to methods and apparatus for securely and easily sharing data over a communications network. As communications services on a communications network are continuously becoming cheaper, faster, and easier to use, more users are becoming receptive to the idea of sharing data over the communications network. However, although E-mails and web folders, to a certain degree, provide easy-to-use or secure data sharing mechanisms, none of the existing data sharing methods is both easy-to-use and highly secure. This disclosure provides methods and apparatus for easily and securely sharing data over a communications network.
