Abstract
A secure method for granting customer access to images and image related services at an image fulfillment center, includes the steps of: scanning a customer film image to generating high and low resolution digital versions of the image; appending a unique ID and associated security key to the high resolution version of the image and storing the appended image at the fulfillment center; encrypting the ID with a shared encryption key and appending the encrypted ID and the security key to the low resolution version of the image and sending the appended low resolution image to the customer; using the security key to encrypt a request for services relating to the high resolution version of the image and sending the encrypted ID with the encrypted request to the fulfillment center; decrypting the ID using the shared encryption key at the fulfillment center and using the decrypted ID to retrieve the appended high resolution version of the image; and retrieving the key from the appended high resolution version of the image and employing the key to decrypt the request for services.
