Customer Identifier Customization via One-Way Algorithm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for customizing customer identifiers in electronic devices either increase manufacturer management costs and risk of errors or compromise security by allowing potential counterfeiting and piracy, as customers must either manage multiple product lines or directly write identifiers, which can be insecure.
Innovation Solution
A method involving steps to send seed data to an electronic device's application interface, generate an identifier using one or more algorithms, and store it in non-volatile memory, optionally authenticating with a password or serial number, using one-way algorithms to ensure security and prevent counterfeiting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the manufacturer writes the identifier into non-volatile memory before the electronic device leaves the factory, then the customer's customization demand is satisfied, but the management cost and stock increase
Solution Approach 1:
The patent extracts the identifier writing operation from the manufacturer's factory process and relocates it to the customer's environment. The customer uses an application interface to write their own identifier into the electronic device's non-volatile memory, eliminating the need for the manufacturer to maintain multiple product lines for different customers.
Solution Approach 2:
The customer performs the identifier customization themselves through an application interface provided by the manufacturer. This self-service approach allows customers to write their own identifiers without manufacturer intervention, reducing the manufacturer's management burden while still achieving customization.
2Ease of operation
If the customer directly writes the identifier into the electronic device through an application interface, then the customization is flexible, but the security is compromised and counterfeiting may occur
Solution Approach 1:
The patent implements preliminary authentication before allowing the customer to write the identifier. The system verifies the customer's identity and authority through authentication procedures, ensuring that only authorized customers can customize their devices. This preliminary security check prevents unauthorized counterfeiting while maintaining customization flexibility.
3Reliability
If one-way algorithms are used to generate identifiers from seed data, then security is improved and counterfeiting is prevented, but the complexity of the customization process increases
Solution Approach 1:
The patent introduces seed data as an intermediary element between the customer and the final identifier. The customer provides seed data through the application interface, and the system uses one-way algorithms to transform this seed data into secure identifiers. This intermediary approach maintains security while keeping the customer's input process simple.

AI summary
The present invention provides a method for customizing customer identifier. To resolve the problems in customizing the identifier in the electronic device by the manufacturer for its customers, such as high management cost, stock, and possibility of error, as well as the security problem in customizing the identifier by the customer itself, and the problem of counterfeiting by others, the method provided comprises generating an irreversible identifier from a seed data input by the customer using some one-way algorithm(s) and storing that identifier in the electronic device. For the manufacturer, both the management cost and the stock are reduced, and the error possibility of the product after leaving the factory as well. For the customer, the security of customizing the identifier is ensured, and its identifier cannot be counterfeited by other peers any more.
