AIS Transceiver Static Data Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Automatic Identification System (AIS) transceivers require static data such as identification numbers to be securely recorded by sellers or professional installers, which can be inconvenient and prone to errors, and do not allow end users to easily transfer ownership or modify their own data.
Innovation Solution
A method and apparatus that enables end users to authenticate and store static data within the transceiver using a data input interface and processor, allowing them to input encrypted data and receive an authentication code from an external service to enable disabled functions, ensuring accurate data recording and allowing for easy ownership transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sellers or professional installers record static data within the transceiver, then data security and accuracy are improved, but device complexity and operational convenience deteriorate
Solution Approach 1:
The transceiver enables end users to independently enter and authenticate their own static data (MMSI, vessel name, call sign) without requiring sellers or professional installers. The device includes an integrated data entry interface and authentication mechanism that allows users to self-configure the device while maintaining data security through cryptographic verification.
Solution Approach 2:
An authentication code generated by an external authentication service acts as an intermediary to verify the legitimacy of static data. The authentication service receives static data from the user, generates a cryptographic authentication code, and the transceiver verifies this code to ensure data integrity without requiring physical presence of authorized personnel.
2Manufacturing precision
If sellers or professional installers record static data, then data accuracy is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The authentication service pre-generates authentication codes based on the static data provided by the user. This preliminary authentication allows the transceiver to quickly verify data accuracy without requiring time-consuming manual verification procedures or the physical presence of authorized personnel during the setup process.
3Reliability
If static data is encrypted and authenticated, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The complex cryptographic authentication process is extracted from the user interface and handled by the authentication service and transceiver processor. The user only needs to provide static data and receive an authentication code, while the heavy lifting of encryption, hashing, and verification is performed automatically by the system, maintaining simplicity despite strong security measures.
Data Source
AI summary
A method and apparatus which ensures that static data entered into a communications device or apparatus is accurate, or at least consistent with data provided to an authentication service. In some embodiments of the invention, the authentication service may maintain a database of static data associated with each communications apparatus and/or verify the validity of at least a portion of the static data.
