Authentication Verifying Chip with Encrypted Data and Holograms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for authenticating products are unreliable due to the ease of counterfeiting, particularly with visual inspection and existing digital authentication systems, as they can be forged or falsified, leading to difficulties in distinguishing authentic from counterfeit items.
Innovation Solution
A method involving an authentication verifying chip with copy-unable information non-removably mounted on a certificate, where the information is encrypted and stored on an RFID chip, and compared with encrypted data on the product, using cryptographic keys to ensure authenticity, incorporating various authentication verifying mechanisms such as metal granules, fibers, holograms, and iridescent substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual inspection by human sense is used to confirm hologram authenticity, then the method is simple and easy to operate, but the reliability is low due to variations in individual ability and environmental conditions
Solution Approach 1:
The patent replaces human visual inspection with an automatic reading device that uses optical or electromagnetic fields to read information from the authentication verifying chip. This substitution eliminates human variability and environmental factors affecting judgment, while maintaining operational simplicity through automated processing.
Solution Approach 2:
The patent creates a digital copy of the authentication information stored in the chip and compares it with the original. The reading device reads the chip information, encrypts it using a public key, and compares the encrypted data with previously stored encrypted data, enabling reliable verification without direct human visual assessment.
2Extent of automation
If digital data from IC chip is used for authentication, then automation is improved, but the system can be easily falsified by copying and writing data to another chip
Solution Approach 1:
The patent applies preliminary anti-action by encrypting the authentication data with a public key before storing it in the chip. This pre-encryption prevents unauthorized copying and falsification, as the encrypted data cannot be read or replicated without the corresponding private key. The system proactively secures against future falsification attempts.
Solution Approach 2:
The patent combines multiple authentication mechanisms within the chip, including encrypted digital data, holographic elements, and potentially physical unclonable features. This composite approach creates a multi-layered authentication system that is difficult to falsify compared to single-method systems.
3Ease of manufacture
If hologram tags are used for authentication, then copying becomes difficult, but not impossible, and skilled falsification can mount fake holograms that are almost impossible to confirm
Solution Approach 1:
The patent embeds multiple authentication layers within the chip structure, including encrypted data, holographic elements, and physical features. The chip itself becomes the container for multiple verification mechanisms, creating a nested authentication system where each layer provides additional security against falsification.
Solution Approach 2:
The patent introduces an intermediary authentication chip that sits between the product and the verification system. This chip contains encrypted authentication data and serves as a mediator that the reading device communicates with, rather than directly verifying physical holograms, thereby enabling more reliable automated confirmation.
4Reliability
If certificates are issued to certify authenticity, then product authentication is enabled, but the certificate itself can be forged
Solution Approach 1:
The patent performs preliminary action by encrypting the authentication data with the manufacturer's public key before the certificate is even issued. This pre-encryption ensures that the certificate cannot be forged, as the encrypted data can only be decrypted with the corresponding private key that only the legitimate manufacturer possesses. The authentication mechanism is established before any potential forgery attempt.
Data Source
AI summary
Authentication verifying for an object to be certified is carried out. An authentication verifying chip in which authentication verifying information is stored is mounted non-removably on a certificate. A confirmation chip in which the authentication verifying information is encrypted by a crypt key of a certificate issuer and is stored is mounted non-removably on the object to be certified. When verifying the authenticity of the object to be certified, the encrypted authentication verifying information in the confirmation chip is decrypted by the crypt key of the certificate issuer, and it is compared to the authentication verifying information in the authentication verifying chip.
