Geo-data spam filters are described. In one or more implementations, origin data and language data of a message are evaluated to establish a score for the message indicating a likelihood that the message is spam. The evaluation includes comparing the origin data and the language data to ranked lists indicating message origins and languages with which a respective message recipient interacts positively and ranked lists indicating message origins and languages with which the respective recipient interacts negatively. Interactions of the respective recipient with previously sent messages may be tracked to form these lists. Based on the score established by evaluating the origin data and the language data of the message, the message is filtered for delivery.

Metering is enabled through an arrangement in which a metering certificate is communicated to a mobile device using an over-the-air protocol. A metering trigger provides the metering certificate that includes a location to which metering data is posted by the mobile device and a public key of a public-private key pair, or alternatively provides a link to such metering certificate. A metering helper passes the metering certificate to a DRM system on the mobile device which collects metering data associated with the metering ID and uses the public key to encrypt the metering data into a metering challenge. The metering helper posts the metering challenge to the location. The metering service extracts the metering data from the metering challenge using a private key and generates a metering response that is received by the metering helper which prompts the DRM system to reset at least a portion of a data store in which the metering data is stored.

Over-the-air delivery of metering certificates and data

Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.
