Abstract: Encrypted information retrieval can include generating a database that is partitioned into shards each having a shard identifier, and database entries in each shard that are partitioned into buckets having a bucket identifier. A batch of client-encrypted queries are received. The batch of client-encrypted queries are processed using a set of server-encrypted data stored in a database. The processing includes grouping the client-encrypted queries according to shard identifiers of the client-encrypted queries, executing multiple queries in the group of client-encrypted queries for the shard together in a batch execution process, and generating multiple server-encrypted results to the multiple queries in the group of client-encrypted queries. The multiple server-encrypted results for each shard are transmitted to the client device.

Abstract: The present disclosure is generally directed a data processing system for authenticating packetized audio signals in a voice activated computer network environment. The data processing system can improve the efficiency and effectiveness of auditory data packet transmission over one or more computer networks by, for example, disabling malicious transmissions prior to their transmission across the network. The present solution can also improve computational efficiency by disabling remote computer processes possibly affected by or caused by the malicious audio signal transmissions. By disabling the transmission of malicious audio signals, the system can reduce bandwidth utilization by not transmitting the data packets carrying the malicious audio signal across the networks.

Abstract: In one aspect, there is provided a method performed by one or more computers for privacy-sensitive assessment of digital component transmission reach based on cardinalities of subset unions of a collection of user sets, the method including: receiving a request to determine a number of users that are included in a target group of users that received at least one transmission of a digital component, where the request includes a set expression defined in terms of the collection of user sets, generating an alternative representation of the set expression in terms of primitive sets, applying a cardinality model to each primitive to generate a cardinality of each primitive set as a linear combination of cardinalities of subset unions of the collection of user sets, and determining the number of users included in the target group of users based on the cardinalities of the primitive sets.

Abstract: A method comprising receiving, at a first computing system, encrypted identifiers, performing, by the first computing system, a concealing operation on the encrypted identifiers to produce concealed encrypted identifiers, wherein the concealing operation conceals the encrypted identifiers from the first computing system and a second computing system but enables matching between the concealed encrypted identifiers, decrypting, by the second computing system, the concealed encrypted identifiers to produce concealed identifiers, analyzing, by the second computing system using one or more match rules, the concealed identifiers to generate one or more associations between the concealed identifiers, and generating, by the second computing system, one or more universal identifiers based on the one or more associations.

Abstract: A method, executed by a processor, is used to determine presence of a viewer at a media device. The method includes receiving viewer biometric data captured by a biometric capture device associated with the media device; determining a category of the viewer based on the captured viewer biometric data; comparing the captured viewer biometric data to a reference to determine a possible identity of the viewer, by: determining a presence probability for the viewer based on a match between the biometric data and the reference, and determining a confidence level for the probability; and when the probability and confidence level equal or exceed a threshold, determining the viewer is present at the media device.

Abstract: A panel provider may transmit queries to an audience measurement server to retrieve measurement data for subsets of clients selected via one or more characteristics, such as characteristics of the client, characteristics of the client's device, characteristics of the received content, etc. To protect panel data, the panel provider need not identify these characteristics to the audience measurement server; rather, queries may be made via a plurality of filters that may be applied to client and/or content identifiers. Because the audience measurement server may apply the filters or data structures to select client data for retrieval without knowing what the filter represents, the panel provider's reason for any particular query may be hidden. For further obfuscation, the panel provider may provide a plurality of filters that individually may identify large numbers of clients, but when intersected or applied together, identify only the clients for whom measurement data is required.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing customized television advertisements. In one aspect, television advertising templates are used for generating customized television advertisements. The television advertisement templates include targeting criteria specifying targeting conditions for the television advertising template, which are conditions for selecting the television advertisement template for an advertisement availability, and content selection criteria specifying availability content associated with an advertisement availability for use in selecting variable advertisement content elements for inclusion in a customized television advertisement generated from the television advertising template. The variable advertisement content elements can include video elements, audio elements, and text elements.

Abstract: To provide secure single-source panel audience measurement data while providing confidentiality and security of panel membership, an audience measurement server may capture content identifiers and client identifiers of devices receiving content. A panel provider may generate a probabilistic data structure via a hash of the client identifiers. The audience measurement server may utilize the filter array to extract a subset of measurement data including the data of the panel members, as well as data of some non-panel members as false positives, without being able to distinguish between the members and non-members. The audience measurement server may encrypt the extracted subset of data with each client identifier corresponding to an item of data as a key, and send the encrypted data to the panel provider, thus including both panel and some non-panel data, with the panel provider only able to decrypt data corresponding to its own panel members.
