  • Patent number: 10970375
    Abstract: Methods, systems, and devices are provided for generating biometric signatures. The system can detect, at an electronic device, one or more biometric acoustic signals. The system can generate a biometric signal input of the one or more biometric acoustic signals. The system can apply a machine learning model to conduct feature extraction of the biometric signal input having one or more biometric acoustic signals. The system can generate a biometric user signature of the user from the machine learning model. The system can perform one or more privacy preserving hashing functions to the biometric user signature to generate a hashed biometric user signature. The system can determine whether the hashed biometric user signature satisfies a predetermined threshold with an enrollment hashed signature of the user. And the system can authenticate an identity of the user upon detecting that the hashed biometric user signature satisfies the predetermined threshold.

  • Publication number: 20200412546
    Abstract: Some embodiments are directed to a system for selectively disclosing attributes and data entries of a record. An issuer device generates a digital signature on a message comprising the attributes and a secret record identifier, and digital signatures on messages comprising respective data entries and each comprising the secret record identifier. The record, secret record identifier, and signatures are provided to a selector device. The selector device selectively discloses attributes and data entries of the record to a receiver device, proving authenticity by means of a zero-knowledge proof of knowledge of the signature on the attributes and signatures on respective data entries. The receiver device verifies the proof with respect to the public key of the issuer and the received attributes and data entries.

  • Publication number: 20200277159
    Abstract: A movement detection system for a passenger in the present invention includes: a first Bluetooth module (150) mounted in an elevator landing area; and a movement prediction unit (270) configured to predict, based on Bluetooth movement data, that a movement of a passenger in the elevator landing area is a normal movement or an abnormal movement. The movement detection system and a movement detection method in the present invention can automatically detect an abnormal movement of a passenger, and are especially applicable to an elevator system that completes an elevator call operation without an input operation.

  • Publication number: 20200239277
    Abstract: The present invention relates to the guidance for a passenger to enter a correct elevator car, belonging to the field of elevator intelligent control technologies. In a method for guiding a passenger to enter a correct elevator car provided in the present invention, the movement of the passenger relative to one of a plurality of elevator cars is determined based on a change in the signal strength of a received first wireless signal; and whether the movement is a movement corresponding to entering a correct elevator car is judged based on a recognition result. The present invention can realize that a passenger is automatically guided to enter a correct elevator car by means of the change in a vibration signal and/or a voice prompt signal.

  • Publication number: 20190185291
    Abstract: The present invention provides an automatic elevator-calling system and an automatic elevator-calling control method, belonging to the technical field of elevator intelligent control technologies. The automatic elevator-calling system and the automatic elevator-calling control method of the present invention can configure an elevator calling distance in an adjustable manner, wherein the elevator calling distance indicates a distance between a personal mobile terminal that can sense a wireless signal and a wireless signal apparatus when the personal mobile terminal automatically sends an elevator calling request command. The present invention can further improve the elevator calling experience of the passenger.

  • Publication number: 20190023527
    Abstract: The present invention relates to tracking of a passenger flow in an elevator car. A passenger flow tracking system for an elevator car according to the present invention includes: a first Bluetooth module installed in the elevator car, the first Bluetooth module being configured to broadcast a first Bluetooth signal that can substantially cover the interior of the elevator car and receive a response fed back by a personal mobile terminal carried by a passenger inside the elevator car; and a passenger flow determining unit configured to at least determine, based on a change in the received response, that the passenger leaves and/or enters the elevator car.
