Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack secure methods for transmitting and decrypting prescription data and calibration data between devices to ensure access is restricted to authorized users and devices, particularly in the context of prescription lenses.
Innovation Solution
The implementation of public and private key encryption systems, where prescription data is encrypted using a lens manufacturer's public key and decrypted using their private key, and calibration data is encrypted using a user's device key, ensuring secure transmission and decryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is transmitted in plaintext between devices, then transmission speed and simplicity are improved, but security and unauthorized access prevention deteriorate
Solution Approach 1:
The patent transforms data from plaintext to encrypted format using cryptographic algorithms, changing the parameter of data representation. This encryption process secures the data during transmission while maintaining the ability to reconstruct the original data at the receiving end through decryption, thus resolving the contradiction between transmission efficiency and security.
Solution Approach 2:
The patent introduces encryption keys as intermediary elements that mediate between the transmitting device and receiving device. These keys enable secure data exchange without requiring the actual data to be exposed during transmission, allowing fast transmission of encrypted data while ensuring security through key-based access control.
2Reliability
If encryption is implemented for data transmission, then security is improved, but system complexity and computational overhead increase
Solution Approach 1:
The patent divides the encryption system into distinct functional components: key generation modules, encryption modules, decryption modules, and key management modules. This segmentation allows each component to be optimized independently and simplifies the overall system architecture by distributing complexity across multiple specialized units rather than requiring a single complex system.
Solution Approach 2:
The patent implements key generation and exchange procedures in advance before actual data transmission occurs. By preparing encryption keys and establishing secure channels beforehand, the system reduces the computational burden during active data transmission, thereby lowering real-time complexity while maintaining strong security measures.
3Reliability
If data is encrypted and stored, then unauthorized access is prevented, but data retrieval and decryption time increase
Solution Approach 1:
The patent performs preliminary decryption operations by maintaining decryption keys in secure memory at the receiving device. When encrypted data arrives, the system can quickly decrypt it using pre-loaded keys rather than performing complex decryption algorithms in real-time, thus reducing decryption time while maintaining security through secure key storage.
Solution Approach 2:
The patent creates and stores copies of decryption keys in secure locations at the receiving device. These key copies enable fast decryption operations without requiring continuous access to the original key generation systems, thereby reducing decryption time while maintaining security through controlled key distribution and storage.

AI summary
Encrypting and securely transmitting data between devices is disclosed. After a device obtains a request to purchase a prescription lens, including prescription data, to be inserted into a second electronic device, the prescription data is securely encrypted and transmitted to the lens manufacturer. The lens manufacturer may create a prescription lens and calibration data related to the lens. The calibration data can be encrypted and transmitted to a storage device for storage. The second electronic device can retrieve the encrypted calibration data from the storage device and utilize it to perform a full calibration of the device. The second electronic device can present images, in accordance with the calibration data, using a display through an optical path that include the prescription lens.
