Реферат: 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 a 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.
