Methods, systems, and apparatus, including computer program products, for generating or using augmentation queries. In one aspect, subject phrases for detection in content are identified. Each phrase has a corresponding cardinality of terms. First hash sets for each of the subject phrases are generated, each first hash set including first hashes of bigram term subsets for each of the phrases. Sub-phrase scores for each of the hashes based on the cardinality of each phrase are assigned. The sub-phrase scores a used to detect the subject phrases in hashes of portions of received content. Other implementations of this aspect include corresponding systems, apparatus, and computer program products.

Phrase matching

Methods, systems, and apparatus, including computer program products, for distributed security system authorization. Client device authentication instructions are executed on a client device to determine if authentication data accessible by the client device authentication instructions are stored at the client device. If the authentication data are stored at the client device, the client device authentication instructions generate authenticated user data and store the authenticated user data at the client device. If the authentication data are not stored at the client device, the client device authentication instructions generate a login environment that allows a user of the client device to input login data. The login data are provided to a verification process that in response to verification provide the authentication data to the client device.
