Abstract
One embodiment relates to a method for providing a service which matches document fingerprints against a database of document fingerprints. Target text data on a mobile phone device is obtained, and target document fingerprints are generated for the target text data using a fingerprint generator on the mobile phone device. The target document fingerprints are transmitted to a service cloud. A feedback message is received from the service cloud. The feedback message depends on results from matching the target document fingerprints against the database of document fingerprints. Other embodiments, aspects and features are also disclosed.
