Secure Media Transfer Appliance for Automated Cloud Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for transferring sensitive digital content from removable memory cards to cloud storage lack security, as they rely on unencrypted formats and human intervention, making them prone to errors and breaches.
Innovation Solution
A secure media transfer appliance that encrypts digital content on the fly, transfers it to a cloud-based storage service, and optionally deletes it from the memory card, ensuring centralized and secure management through a multi-interface system with encryption and key delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital content is transferred in unencrypted format for ease of access, then ease of operation is improved, but security is worsened
Solution Approach 1:
The system changes the encryption state parameter of digital content dynamically - maintaining encrypted state during storage and transmission, and transitioning to decrypted state only during authorized playback. This resolves the contradiction by allowing easy access (playback) while maintaining security (encrypted storage/transmission).
Solution Approach 2:
The patent introduces an intermediary decryption and playback system that acts as a secure gateway between encrypted cloud storage and authorized users. The intermediary holds decryption keys and controls access, enabling easy playback for authorized users while maintaining security in the cloud storage system.
2Device complexity
If multiple memory cards are managed manually, then device complexity is reduced, but reliability is worsened due to human error
Solution Approach 1:
The system implements self-service automated management where the cloud-based platform automatically performs content verification, encryption, secure storage, and key management without requiring manual human intervention. This resolves the contradiction by reducing manual complexity while enhancing reliability through automated security protocols.
Solution Approach 2:
The system performs preliminary encryption and verification actions automatically before content is stored or accessed. By pre-configuring security measures and automated management protocols, the system eliminates the need for manual security management while maintaining high reliability.
3Reliability
If encryption is applied to digital content before cloud upload, then security is improved, but ease of operation is worsened
Solution Approach 1:
The patent introduces an intermediary automated encryption system that handles the complexity of encryption transparently. The intermediary manages key generation, content encryption, and secure storage automatically, improving security while maintaining ease of use by eliminating manual encryption steps from the user workflow.
Solution Approach 2:
The system implements self-service automated encryption where the cloud platform automatically encrypts content upon upload and manages decryption keys. This resolves the contradiction by applying strong encryption (improving security) while requiring no manual encryption operations from users (maintaining ease of operation).
Data Source
AI summary
A data transfer device including an enclosure with a plurality of input/output connection ports, a processor, a memory including a data store, and a data transfer component. The data transfer component directs the processor to transfer data from an external data source via at least one of the plurality of input/output connection ports, encrypt the transferred data, store the encrypted data on the data store, responsive to a successful transfer of the encrypted data to the data store, delete the data from the external data source, establish a connection to an external data storage service, responsive to a successful connection to the external data storage service, transfer the encrypted stored data to the external data storage service, responsive to a successful transfer of the encrypted stored data to the external data storage service, deleting the encrypted stored data from the data store.
