Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless identification tag verification technologies are vulnerable to counterfeiting due to direct copying of passwords or limitations in data writing and reading capabilities across different operating systems, leading to ineffective anti-counterfeiting mechanisms.
Innovation Solution
A three-layered anti-counterfeiting mechanism using a mobile device, verification server, and wireless identification tag, involving a time-based one-time password algorithm, encryption, and multiple verification steps to ensure secure information transmission and prevent direct copying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless identification tag stores a password and product information encoded in advance, then consumers can verify product information, but counterfeiters can directly copy the information in the tag
Solution Approach 1:
The patent implements dynamic password generation using a time-based one-time password (TOTP) algorithm. Instead of storing static passwords in the wireless identification tag, the system generates passwords that change over time based on a timestamp and seed value. This dynamic approach prevents counterfeiters from copying static information, as each password is valid only for a specific time window and cannot be reused or replicated without the secret key.
Solution Approach 2:
The patent changes the parameter of password stability to password variability. By using TOTP algorithm with time-based parameters, the password transforms from a static value to a dynamically changing value. The password is generated based on current time and a secret key, ensuring that even if one password is compromised, it becomes invalid after the time window expires, thereby preventing counterfeiting through information copying.
2Object-affected harmful factors
If a variable password method is used with read-write RFID tags, then anti-counterfeiting capability is enhanced, but electronic devices with different operating systems cannot write request signals into the tag
Solution Approach 1:
The patent implements self-service functionality in the mobile device by integrating the TOTP algorithm directly into the application. Instead of requiring the wireless identification tag to generate passwords (which would need specialized read-write capabilities across different operating systems), the mobile device itself generates the password locally using its own processor and the TOTP algorithm. This eliminates the need for the tag to have complex write capabilities while maintaining strong anti-counterfeiting protection.
Solution Approach 2:
The patent introduces a verification server as an intermediary that coordinates between the mobile device and the wireless identification tag. The server manages the verification process by receiving the tag's identification code, generating the corresponding time-based password, and verifying it against the tag's response. This intermediary approach allows the system to use simple read-only tags while maintaining security through server-mediated password verification, avoiding operating system compatibility issues.
3Reliability
If authentication data is transmitted over a network between wireless tag and authentication server, then mutual authentication can occur, but transmission delays and data theft risks increase
Solution Approach 1:
The patent performs preliminary action by pre-generating time-based passwords on both the mobile device and the verification server before the actual authentication interaction with the tag. The mobile device generates a password based on the current timestamp and secret key, then immediately uses it to verify the tag's response. This preliminary password generation eliminates the need for multiple back-and-forth network communications, reducing authentication delay while maintaining security through time-based verification.
4Object-affected harmful factors
If a three-operation verification process is implemented, then counterfeiting is prevented, but verification complexity increases
Solution Approach 1:
The patent implements a multi-functional verification system where a single mobile device application handles multiple verification operations: generating time-based passwords using TOTP algorithm, communicating with the verification server, and validating the wireless identification tag's response. This universal approach consolidates what could be multiple separate complex systems into one integrated solution, reducing overall system complexity while maintaining the three-operation verification process for strong counterfeiting prevention.

AI summary
A product authenticity verification system and a method for using the same provide a three-layered anti-counterfeiting mechanism. First, verification is performed to determine whether a first identification code and a digital signature of a wireless identification tag are same as information stored in a database of a verification server. Second, a tag password verification operation, checked by the tag, needs to be passed before reading content of the tag. Third, a ciphertext and a second identification code for checking the tag are verified. When the above two operations are passed and a read count value of the tag is greater than that stored in the database, the server can determine authenticity of the tag. Because the tag requires the three-operation process each time for verification, and demands a correct password to read the content of the tag, the authenticity of the product and a trademark displayed thereon can be verified.
