Event-Specific Key Distribution for Secure Image Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in sharing large collections of digital images from events, such as weddings or conferences, as they often contain personal or sensitive information, making it difficult to distribute them securely and accessibly while controlling who can view the content.
Innovation Solution
A method involving the identification and transmission of encryption keys associated with events, allowing attendees to encrypt and decrypt data using these keys, enabling secure sharing of sensitive information through publicly accessible platforms like websites or email, while ensuring only attendees can access the decrypted data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images are published in a publicly accessible manner on a website, then accessibility and distribution are improved, but security and privacy control deteriorate
Solution Approach 1:
The patent applies preliminary action by encrypting images with event-specific keys before publishing them on publicly accessible websites. The encryption is performed in advance, allowing the images to be freely distributed while maintaining security. Attendees receive their decryption keys at the event, enabling them to access the images later without compromising privacy during the publication phase.
2Object-affected harmful factors
If encryption is applied to protect sensitive information, then security is improved, but device complexity and operational difficulty worsen
Solution Approach 1:
The system applies self-service by automatically generating event-specific encryption keys and distributing them to attendees through wireless transmitters at the event. The camera device automatically encrypts images with the appropriate key without requiring manual intervention from the user. This automation significantly reduces the complexity of key management while maintaining strong security.
Solution Approach 2:
The patent implements a universal key distribution system where a single wireless transmitter at the event can distribute encryption keys to multiple attendees simultaneously. The system serves multiple functions: it generates keys, transmits them wirelessly, and manages the encryption process, simplifying the overall complexity while providing comprehensive security.
3Productivity
If large numbers of images are distributed, then productivity and sharing capability are improved, but loss of time and energy in transmission worsen
Solution Approach 1:
The patent applies segmentation by dividing the image distribution process into two independent phases: (1) uploading encrypted images to a website, which can be done quickly without transmitting large amounts of data over slow connections, and (2) allowing attendees to download and decrypt images at their convenience. This segmentation eliminates the time-consuming real-time transmission of large image files while maintaining high productivity in the distribution process.
Data Source
AI summary
Methods of encryption and decryption are described which use a key associated with an event to encrypt/decrypt data associated with the event. The method of encryption comprises identifying a key associated with an event and encrypting data using the identified key. The encrypted data is then published along with details of the event.
