11,086,849, "Methods and systems for reading data based on plurality of blockchain networks," assigned to Advanced New Technologies Co., Ltd. (KY)
Disclosed are methods and systems for retrieving data based on a plurality of blockchain networks. One method comprises: receiving a first-type transaction hash sent by a user, wherein the first-type transaction hash is a hash value of a first-type blockchain transaction associated with a first-type blockchain network, wherein the first-type blockchain network and the second-type blockchain network are comprised in a data recording system; identifying a second-type blockchain transaction that comprises the first-type transaction hash; identifying a network identifier from the second-type blockchain transaction; identifying a first-type blockchain transaction corresponding to the first-type transaction hash from a blockchain of a first-type blockchain network corresponding to the network identifier; and providing the first-type blockchain transaction to the user.
11,080,671, "Identifying copyrighted material using embedded copyright information," assigned to Advanced New Technologies Co., Ltd. (KY)
A method includes generating, by a computing device, a unique identifier (ID) based on copyright information associated with the textual content, wherein the copyright information and the textual content are recorded on a blockchain of a blockchain network; identifying, by the computing device, one or more attributes associated with fonts used in the textual content; and embedding, by the computing device, the unique ID in the textual content by changing the one or more attributes associated with the fonts to be representative of the unique ID, wherein the embedding produces information-embedded text enables retrieval of the copyright information from the blockchain based on the unique ID, and wherein a visual difference between the textual content and the information-embedded text is not apparent to an unaided
