    摘要: A system and method that facilitates the authentication of streamed data received at a device, where authentication information is not distributed over the data stream. One embodiment of a method of authenticating data comprises the steps of: receiving, at the device, data in a plurality of packets transmitted by a data server; submitting a request for a server-computed authentication value to a data authentication server, wherein the data authentication server is adapted to compute the server-computed authentication value based on a subset of the data transmitted by the data server; receiving, at the device, the server-computed authentication value from the data authentication server in response to the request; computing a device-computed authentication value based on a subset of the data received at the device corresponding to the subset of the data transmitted by the data server; and determining if the subset of the data received at the device is authentic by comparing the server-computed and device-computed authentication values.

    摘要: A device and method for generating user notifications associated with tasks that are pending completion on a mobile device. When additional input is required from a user of the mobile device to complete performance of a task and is not being received from the user within a predefined time period, at least one form of user notification is generated. The particular form or forms of user notification are defined by a user profile associated with the user. User notifications may comprise visual, audible, and/or vibratory alerts, and different forms of these user notifications may be generated in a sequence. The volume of audible alerts or the period between periodic user notifications may vary over time.

    摘要: A system and method for managing memory in a mobile device to prevent the swapping out of sensitive data to non-volatile storage from a volatile memory, to provide enhanced security for the sensitive data. In one broad aspect, there is provided a method of managing memory in a mobile device comprising the steps of identifying one or more data objects stored in a volatile memory on the mobile device to be swapped out to a non-volatile storage component, determining objects marked as containing sensitive data, and retaining so-marked objects in the volatile memory of the mobile device.

    摘要: A system and method for processing messages with encryptable message parts. When constructing an encoded message, an encryption key of a plurality of identified encryption keys is used to encrypt message data of a message part. A key identifier is associated with the message part and identifies the encryption key used for the encryption of the message data of the message part. In at least one exemplary embodiment, encryption keys that are used to encrypt message data of message parts are provided in a separate message part, arranged by key identifier. In particular, the encryption keys, arranged by key identifier, may be provided in exactly one message part separate from the message parts containing message data. This allows for a compact message encoding.
