Abstract: A privacy-aware query management system receives a query to aggregate data from a number of datasets, wherein at least one of the datasets contains private information for one or more people. The privacy-aware query management system retrieves data from the datasets. Each of the plurality of datasets has associated privacy parameters that determine a level of noise to be applied to query results obtained from that dataset, and the levels of noise are used to determine an order of operations for the query to retrieve the data from the datasets. The privacy-aware query management system applies the levels of noise to each query result obtained from each of the datasets in accordance with the privacy parameters associated with that dataset, computes aggregated data from the query results with the levels of noise applied, and responds to the query with the aggregated data.

Abstract: A method and system for secure authentication of a mobile computing device (MCD) are described. Data that identifies the MCD is obtained. Identification data is exchanged with a network service, which sends embedded data to trigger a secure browser instance on the MCD. A secure single action link specific to the requesting device is then provided, the secure single action link being actionable to communicate to the network service, through the secure browser instance, a session token corresponding to the mobile computing device. The user can perform a selection action on the secure single action link to authenticate the MCD.

Abstract: A model is implemented that includes one or more classes. For each of the one or more classes of the model, a set of input variables of the big data set are represented as a matrix with non-zero values only provided as diagonal entries. A most likely class for each input variable is determined based at least in part on inverting the matrix. One or more predictions are determined for one or more output variables based at least in part on the most likely class of one or more input variables from the set of input variables.

Abstract: A method and system are described for detecting unauthorized access to one or more of a plurality of networked victim computers in a victim cloud. The networked victim computers connect to one or more DNS servers. The system includes one or more decoy bot computers, which are operated as victim computers in the victim cloud. The system also includes one or more decoy control computers, which are operated as control computers that communicate with victim computers in the victim cloud. Threats are identified by analyzing data traffic communicated with the decoy bot computers and decoy control computers for information suspected of having being sent from a victim's computer without proper authorization, and by monitoring whether behavior of a DNS server deviates from expected behaviors.

Abstract: A method and system for authenticating answers to Domain Name System (DNS) queries originating from recursive DNS servers are provided. A verification component provides a verification that a DNS query originated from the recursive DNS server. An authoritative DNS server receives the query via a network, such as the Internet, and provides an answer to the query to an authentication component. The authentication component then provides an authentication, such as a digital signature, which confirms that the received answer was provided by the authoritative DNS server, and then communicates the answer and the authentication to the verification component via the network. The verification component then verifies that the authentication corresponds to the received answer and sends the answer to the recursive DNS server. When the verification component receives an answer in the absence of a corresponding authentication, the verification component drops the answer.
