Patent number: 8139901Abstract: A method and system for nano-encoding and decoding information related to printed texts and images on paper and other surfaces is provided. The system and method includes a nano-encoder for encoding information related to printed texts and images; and then collocating the encoded information with the related printed texts and/or images. The system also includes a nano-decoder for decoding information encoded by the nano-encoder. The nano-decoder includes a text processing database having a translator database. The translator database includes a definition database; and a summary database. In addition, the system and method includes detecting luminescent nano particles and/or magnetic nano particles; and determining invariant properties of the detected nano particles. The invariant properties are then matched with coded information.Type: GrantFiled: July 8, 2011Date of Patent: March 20, 2012Assignee: International Business Machines CorporationInventors: Dimitri Kanevsky, Dmitri V. Talapin
