Abstract
Various embodiments of the teachings herein include a method for information management of product manufacture. An example method includes: storing a public key for verifying average carbon emission value of a batch of products in a first blockchain; storing a hash value of a carbon emission value of each product of the batch of products in a second blockchain; and determining a difference value between the carbon emission value of a particular product and an average carbon emission value of the batch of products and comparing the difference value to a threshold using product manufacture information to verify the carbon emission value of each product of the batch of products.
Claims10
A method for information management of product manufacture, the method comprising:
- storing a public key for verifying average carbon emission value of a batch of products in a first blockchain;
- storing a hash value of a carbon emission value of each product of the batch of products in a second blockchain;
- and
- determining a difference value between the carbon emission value of a particular product and an average carbon emission value of the batch of products and comparing the difference value to a threshold using product manufacture information to verify the carbon emission value of each product of the batch of products.
An apparatus for information management of product manufacture, the apparatus comprising:
- a first storage module for storing a public key for verifying average carbon emission value of a batch of products in a first blockchain;
- a second storage module for storing a hash value of a carbon emission value of each product of the batch of products in a second blockchain;
- and
- a determination module for determining a difference value between a carbon emission value of the product and average carbon emission value of the batch of products and comparing the difference value to a threshold using product manufacture information to verify the carbon emission value of each product of the batch of products.
