Document fingerprinting for mobile phones

摘要

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.

1. A method for providing a service which matches document fingerprints against a database of document fingerprints, the method comprising:
obtaining target text data on a mobile phone device; generating target document fingerprints for the target text data using a fingerprint generator on the mobile phone device; transmitting the target document fingerprints from the mobile phone device to a service cloud; and receiving a feedback message by the mobile phone device from the service cloud, wherein the feedback message depends on results from matching the target document fingerprints against the database of document fingerprints, wherein the fingerprint generator on the mobile phone device comprises a lower-density fingerprint generator, and wherein indexed document fingerprints in the database of document fingerprints are generated by a higher-density fingerprint generator.
