Abstract: Provided is a computer implemented method of providing a blockchain based traceability service. The method comprises, for each secret from a set of secrets associated with respective ones of a set of parameters for a traceable item, generating a proof to provide a set of proofs. The method includes generating a ciphertext based on a public data encryption key from a set of public data encryption keys associated with said parameters for the traceable item, and information of said traceable item. The preceding step is repeated for each pair of identifier and public data encryption key. The method involves uploading to the blockchain the generated ciphertext, the respective identifier, a hash value of the respective secret, and the respective proof for each parameter of the traceable item, verifying in the blockchain the set of uploaded proofs, and storing verified data in the blockchain.

Abstract: The invention provides a computer-implemented method and system for analyzing texts. The method comprises the steps of identifying one or more sentences of a first text in a first language; identifying one or more sentences of a second text in a second language; translating the identified one or more sentences of the first text from the first language into the second language; processing the sentences of the first text in the second language and the sentences of the second text in the second language into a first representation of the sentences of the first text, and a second representation of the sentences of the second text; and comparing the first representation of sentences of the first text with the second representation of sentences of the second text to identify one or more sentences of similarity between the first text and the second text.
