Abstract
A method for authorizing a computer program having a number of features for use with a product includes: receiving license data generated using a first key, the license data specifying a unique identifier associated with the product and specifying at least one feature authorized for use with the product; using a second key associated with the first key, obtaining the unique identifier from the license data; retrieving a product identifier from the product; determining whether the unique identifier corresponds to the product identifier; and based on the determination, authorizing use of the at least one feature with the product.
