Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual password input is used for identity verification, then security can be maintained, but information exchange efficiency deteriorates due to time-consuming input and potential errors
Solution Approach 1:
The wearable device automatically performs identity verification by encrypting information with a pre-stored encryption key corresponding to the logged-in ID, eliminating the need for manual password input. The system self-verifyes user identity through the encryption/decryption process between wearable device and server, significantly improving information exchange efficiency while maintaining security
Solution Approach 2:
The patent replaces the mechanical manual password input process with an automated cryptographic system. Instead of manually typing passwords, the system uses encryption keys stored in the wearable device to automatically verify identity through encryption and decryption operations, substituting human manual operation with automated computational processes
2Reliability
If complicated passwords are used for identity verification, then security is improved, but input time increases and input errors occur
Solution Approach 1:
The encryption key is pre-stored in the wearable device before the information exchange process begins. This preliminary setup allows the system to perform automated identity verification without requiring users to input complicated passwords during the actual exchange, eliminating time loss while maintaining strong security through the pre-configured cryptographic key
3Reliability
If manual password input is required, then identity verification can be performed, but the process becomes prone to input errors affecting exchange completion
Solution Approach 1:
The patent replaces the error-prone manual password input mechanism with an automated cryptographic verification system. The wearable device automatically encrypts information using a pre-stored key, and the server decrypts and verifies it, eliminating human input errors while maintaining reliable identity verification and improving overall exchange efficiency

AI summary
An information exchange method and device are provided. The method includes: establishing a connection with a wearable device; sending information to be exchanged corresponding to a logged-in ID to the wearable device via the connection; receiving a first encrypted result returned by the wearable device; generating a first verifying factor corresponding to the first encrypted result with a predetermined algorithm; sending the information to be exchanged and the first verifying factor in an associated manner to a server; receiving a message sent by the server indicating that an exchange is finished, the message is sent if the server determines that a second verifying factor generated with the predetermined algorithm and corresponding to a second encrypted result is same as the first verifying factor, wherein the second encrypted result is obtained by encrypting the information to be exchanged by the server with the pre-stored encryption key.
