Abstract: The present disclosure provides a data maximum/minimum value (max/min) aggregation method and system for privacy protection. A Paillier cryptosystem is used to encrypt user data, so as to protect privacy and security of user health data. Further, time aggregation is implemented to help a control center obtain an overall health condition of a client in one aggregation period. By using a homomorphic property of the Paillier cryptosystem, the present disclosure implements aggregation of a max/min of privacy protection, and helps the control center obtain a max or a min of health data of the client in the aggregation period.

Abstract: The disclosure provides a multimodal speech recognition method and system, and a computer-readable storage medium. The method includes calculating a first logarithmic mel-frequency spectral coefficient and a second logarithmic mel-frequency spectral coefficient when a target millimeter-wave signal and a target audio signal both contain speech information corresponding to a target user; inputting the first and the second logarithmic mel-frequency spectral coefficient into a fusion network to determine a target fusion feature, where the fusion network includes at least a calibration module and a mapping module, the calibration module is configured to perform mutual feature calibration on the target audio/millimeter-wave signals, and the mapping module is configured to fuse a calibrated millimeter-wave feature and a calibrated audio feature; and inputting the target fusion feature into a semantic feature network to determine a speech recognition result corresponding to the target user.

Abstract: A physical token-based centralized authentication system for IoT devices is provided. The system transfers authentication of the IoT device on cloud to the IoT gateway for centralized authentication. User may respond on the IoT gateway via a U2F token to complete authentication of the IoT device. By transferring a kernel of authentication from a large number of scattered single IoT terminals to nodes of the trusted IoT gateway, the system overcomes defects such as numerous IoT devices, limited terminal resources, high authentication cost, and cumbersome operations while enhancing security of the IoT environment, thereby enhancing security of authentication for IoT environment and improving efficiencies of device authentication and management.

Abstract: A method and sensor array for identification of an analyte is disclosed. The method comprises preparing a plurality of solutions at a plurality of pH values of at least one fluorescent poly(para-phenyleneethynylene) and its complex(es), exposing the complex analyte to the plurality of the solutions and measuring the fluorescence intensity of the exposed complex analyte. The fluorescence intensity is compared with a library and the complex analyte identified from the comparison.

Abstract: The present invention relates to the field of medical technology, and in particular, to a variety of substituted N-(5-(quinolin-6-yl)pyridin-3-yl) benzsulfamide derivatives represented by formula (1) (groups therein are as defined in the specification). The compounds according to the present invention have favorable anti-tumor activity against human lung cancer, colon cancer, liver cancer, breast cancer and glioblastoma multiforme, which contribute to development of highly effective, low toxic and high specific anti-tumor drugs, and have high value of development. The present invention also relates to a composition, preparation method and use thereof in the preparation of anti-tumor drugs.

Abstract: An asynchronous access controller comprising a subscriber profiler, a piracy detector and a password injector. The subscriber profiler configured to aggregate both information about subscribers together with information about each associated WLAN. The piracy detector is configured to detect whether wireless communications usage of at least one of the WLANs exceeds at least one parameter specified in a service level agreement (SLA) with the associated subscriber. The password injector controller is configured to inject a new network access password into one or more of the nodes of the WLAN responsive to an affirmative determination by the piracy detector; whereby subsequent network access is selectively revoked on the WLAN in a manner which returns communications usage thereon into conformance with the SLA for the associated subscriber.

Abstract: The disclosed subject matter relates to an architecture that can facilitate safety-oriented navigation through a local environment that presents emergency dynamics. The architecture can facilitate monitoring of deployed sensors constituting a sensor network, even for cases in which sensor locations are not known in advance such as for rapid or random deployment.

Abstract: A system and method for RFID privacy-preserving authentication is disclosed. The method first has a reader sending a request and a first random number to a tag. The tag then generates a second random number. A plurality of hash values are then computed at the tag. Each hash value uses the first random number, the second random number and at least one part of a key of the tag as inputs. The second random number and the computed hash values are then sent to the reader. Lastly, the reader identifies a validity of the tag from the received values. The hash values are all generated in parallel and are independent to each other.
