  • Patent number: 8555342
    Abstract: A technique provides secure access to a set of credentials within a data storage system. The technique involves obtaining a unique identifier (e.g., a hostname which is unique to the system) and a set of stable values (e.g., machine-generated codes which are random to users of the system); and, in response to a storage request from a client application, storing a set of credentials of the client application within a data security mechanism of the data storage system. The set of credentials is in encrypted form when stored within the data security mechanism of the data storage system. The technique further involves configuring the data security mechanism of the data storage system to provide the set of credentials in non-encrypted form in response to new fingerprints matching a system fingerprint which is formed at least in part from the unique identifier and the set of stable values.

  • Patent number: 7821974
    Abstract: A UMTS extension to the GSM/GPRS RIL is disclosed. The UTMS RIL provides an API set interface for the support of UMTS features such as 3G QoS, secondary PDP contexts call, priority service, voice group call and voice broadcast services, etc. The API set is based on the UMTS AT command interface as defined in 3GPP specification TS 27.007. The architecture of the UMTS RIL is designed as a standard interface with APIs and callback mechanisms that can be used across different platforms and multi-radio hardware such as GSM, GPRS, WCDMA, and HSDPA. The UTMS RIL may enable various applications running on mobile platforms in 2G, 2.5G, and 3G cellular radio stacks to issue commands without knowledge of underlying radio hardware structure.

  • Patent number: 7406176
    Abstract: Subject matter includes exemplary systems and related methods for fully scalable encryption of scalable multimedia. A scalable bitstream encrypted using the subject matter maintains full functionality of scalable features in the encrypted form. The exemplary scalable encryption allows transcoding, rate shaping, and other operations directly on the ciphertext without degradation of scalable compression efficiency and error resiliency.
