    Abstract: Aggregated transaction data from a transaction data provider may be encrypted and exchanged with a content item selection system using commutative encryption algorithms. The transaction data provider and content item selection system may utilize a set of common identifiers that are each encrypted using a respective commutative encryption algorithm of the transaction data provider or content item selection system. The other of the transaction data provider or content item selection system encrypts the single-encrypted common identifier using a respective commutative encryption algorithm to generate double encrypted common identifiers. The double encrypted common identifiers may be used to match a set of common identifiers with transaction data. The transaction data may be encrypted and/or may include random offset values.

    Abstract translation: 来自事务数据提供者的聚合事务数据可以使用交换加密算法与内容项选择系统进行加密和交换。 交易数据提供者和内容项目选择系统可以利用一组共同的标识符，每个公共标识符使用交易数据提供者或内容项目选择系统的相应的交换加密算法进行加密。 交易数据提供者或内容项选择系统中的另一个使用相应的交换加密算法加密单加密的公共标识符，以生成双加密的公共标识符。 双加密公用标识符可以用于将一组公共标识符与事务数据进行匹配。 交易数据可以被加密和/或可以包括随机偏移值。

    Abstract: A computing device receives voice input that includes first voice input from a first user and second voice input from a second user. The computing device may determine, based at least in part on the received voice input, a change in possession of the computing device. The computing device may determine, based at least in part on the first voice input and the second voice input, delegation of the computing device from the first user to the second user. The computing device may, in response to determining the change in possession of the computing device and the delegation of the computing device, change at least a level of access to functionality of the computing device from a first level of access to a second level of access.

    Abstract: A method of measuring a campaign performance includes transforming identifiers into non-identifiers, and providing the non-identifiers to an external processing party; receiving encrypted non-identifiers comprising the non-identifiers after encryption by the external processing party, other non-identifiers, spending values, and a public cryptographic key, each member of the other non-identifiers being associated with a corresponding member of the spending values; encrypting the non-identifiers to generate other encrypted non-identifiers, and determining an intersection of the encrypted non-identifiers and the other encrypted non-identifiers to generate common encrypted non-identifiers; identifying a subset of the spending values associated with members of the encrypted non-identifiers in the common encrypted non-identifiers; and deriving a total spending value based on the subset of the spending values.

    Abstract: Processing a query, includes, at a client, receiving a user-generated query having a plurality of recognizable terms, securing the user-generated query to generate an encrypted query, so that the plurality of recognizable terms generated by the user-generated query cannot be determined by a server, transmitting the encrypted query to the server, to perform the query on encrypted data comprising a mix of regular data and secure data previously provided by the client, wherein at least one of selection criteria of the query and identifies of selected records of the query result cannot be determined by the server, and interpreting a result of the query provided by the server, and providing an output of the query to the user having the plurality of recognizable terms.

    Abstract: Example implementations described herein are directed to authentication based on the user's private factors, while not revealing at the server side information allowing the server (or anyone with the server's information) to deduce the private answers. In example implementations, the user answers a questionnaire with authentication factors, wherein the answers are transformed in a one-way fashion and the transformed answers are provided to the server side. Example implementations facilitate authentication based on polynomial interpolation or other methods to permit a user to authenticate, even if the user does not answer all of the questions correctly.
