Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Face recognition data security is compromised during transmission and processing due to potential tampering or leakage, especially in image acquisition apparatuses and recognition terminals, which affects the accuracy and reliability of facial recognition systems.
Innovation Solution
Incorporating an encryption processor within the image acquisition apparatus to encrypt image data using a stored key, generating ciphertext data, and a decryption module in the server to decrypt this data, ensuring secure transmission and verification processes, including live-body detection and signature verification to prevent tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face data is transmitted from image acquisition apparatus to recognition terminal, then face recognition function is enabled, but face data may be tampered with or leaked during transmission
Solution Approach 1:
The patent applies preliminary action by encrypting the face data at the source (image acquisition apparatus) before transmission occurs. The encryption processor in the image acquisition apparatus encrypts the face data using a stored key, so that the data is already protected when it leaves the acquisition device. This prevents tampering and leakage during transmission without requiring complex security measures at the receiving end.
2Reliability
If encryption module is added to recognition terminal, then face data security is improved, but device complexity increases
Solution Approach 1:
The patent extracts the encryption function from the recognition terminal and places it in the image acquisition apparatus. By moving the encryption processor to the source device, the recognition terminal only needs to receive and process already-encrypted data, significantly reducing its complexity while maintaining security. The terminal device structure remains simple as it doesn't require additional encryption modules.
3Reliability
If face data is encrypted in image acquisition device, then data security during transmission is improved, but encryption processing time is added
Solution Approach 1:
The encryption is performed as a preliminary action immediately when the face data is captured, before any transmission or processing occurs. This timing ensures that the encryption processing time is minimal and does not add to the overall system response time, as the data is already encrypted when ready for transmission. The security is improved without significant time loss.
