Surgical Robot Data Logger Authentication via Machine-Readable Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for secure measures to prevent unauthorized access and ensure the integrity of sensitive data collected during robotic surgical procedures, as high volumes of data are being collected and distributed without adequate technical safeguards.
Innovation Solution
A surgical robotic system that includes a data logger and a portable user terminal, both equipped with cameras and capable of generating and decoding machine-readable codes to authenticate users and log their identities securely, ensuring that only authorized personnel are associated with specific procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is collected and distributed without sufficient technical safeguards, then data distribution efficiency is improved, but security and authorization control deteriorate
Solution Approach 1:
The system performs preliminary authentication by capturing images of machine-readable codes (containing user identity, terminal identity, timestamp, and signature) before allowing data access. This preliminary verification ensures that only authorized users can retrieve data, preventing unauthorized access while maintaining efficient data distribution for authenticated users.
Solution Approach 2:
The patent introduces machine-readable codes as an intermediary authentication mechanism between the data distribution system and users. These codes contain encoded verification information (identity, timestamp, signature) that mediates the authorization process, enabling secure data distribution without requiring complex real-time verification systems.
2Reliability
If authentication mechanisms are added to secure data access, then data security is improved, but system complexity increases
Solution Approach 1:
The system uses machine-readable codes (such as QR codes or barcodes) that contain copied authentication information (user identity, terminal identity, timestamp, and signature) in a compact visual format. This copying approach simplifies the authentication process by replacing complex cryptographic verification with straightforward code scanning and decoding, reducing system complexity while maintaining security.

AI summary
A surgical robotic system comprising: a surgical robot; a user interface console coupled to the surgical robot whereby a user can control motion of the surgical robot; a data logger for logging data from a surgical procedure performed by means of the robot; and a portable user terminal; the system further comprising: a display controllable by one of the data logger and the user terminal, that one of the data logger and the user terminal being configured for displaying a machine-readable code whereby the data logger or a user of the user terminal can be identified; and a camera coupled to the other of the data logger and the user terminal; the said other of the data logger and the user terminal being configured to, on receiving from the camera an image of a machine-readable code, decode that code to identify the data logger or a user of the user terminal and to cause the identified entity to be logged in association with a procedure performed by means of the robot.
