Abstract
Techniques for generating fingerprints for articles and using the fingerprints for various applications. Scan-related parameter values, including the area of an article scanned, may be specified and varied from one scan to another for collecting data points used for generating fingerprints for articles. A paper shredder is provided that is configured to, prior to shredding a paper sheet, scan the paper sheet and generate a fingerprint for the paper sheet. Fingerprints may also be generated for media keys that are used to access media data. The fingerprint generated for a media key may be used to authenticate the media key. Access to media data corresponding to the media key may be made contingent on successful authentication of the media key.
