  • Patent number: 10341314
    Abstract: A method of security and verifiability of an electronic vote, comprising reception of a temporary voting ballot, during which a temporary voting ballot is received by a voting entity, the temporary voting ballot being encrypted by a public voting encryption key; reception of a validation voting ballot, during which a validation voting ballot is received from the voting entity, the validation voting ballot being encrypted by a public validation encryption key; decrypting the validation voting ballot by a private validation key associated with the public validation encryption key; validating a validation request generated from the decrypted validation voting ballot sent to the voting entity; the preceding steps being repeated until the acceptance of the validation request by the voting entity, after which the encrypted temporary voting ballot is registered as a definitive voting ballot awaiting its counting.

  • Publication number: 20150066976
    Abstract: In embodiments, one or more computer-readable media may have instructions stored thereon which, when executed by a processor of a computing device, provide the computing device with a recurring text identification service. The recurring text identification service may be configured, in some embodiments, to receive a request to identify recurring text within a plurality of documents. The recurring text identification service may be further configured to analyze individual segments of the plurality of documents to generate segment identifiers respectively associated with the segments. In embodiments, the segment identifiers may be based on content of the segments. In embodiments, segments with the same content may have equivalent segment identifiers.

  • Publication number: 20050095587
    Abstract: The present invention provides purified disease detection and treatment molecule polynucleotides (mddt). Also encompassed are the polypeptides (MDDT) encoded by mddt. The invention also provides for the use of mddt, or complements, oligonucleotides, or fragments thereof in diagnostic assays. The invention further provides for vectors and host cells containing mddt for the expression of MDDT. The invention additionally provides for the use of isolated and purified MDDT to induce anitbodies and to screen libraries of compounds and the use of anti-MDDT antibodies in diagnostic assays. Also provided are microarrays containing mddt and methods of use.
