Abstract: Sensor-based authentication technique embodiments are presented which generally employ sensor readings captured by a user's computing device (such as a mobile computing device like a cell phone, smart phone, PDA, and so on) to authenticate the user's access to a computer network-based service (such as a web-service) that is secured with traditional textual passwords. These traditional passwords are saved in an off-device password repository service. The aforementioned sensor readings are not cached on the user's computing device and are immediately streamed to the password repository service, where they are validated against a pre-arranged, known sensor-based password. If the validation succeeds, access to the password protected service is brokered by the password repository service on behalf of the user using the appropriate traditional password, and the user's computing device is granted access.

Abstract: A coding framework that provides conversions between one or more video formats without the use of a transcoder. A video information stream that includes color information formatted in accordance with a first color space sampling format is split into a base stream and an enhanced stream. The base stream is formatted in accordance with a second color space sampling format. The enhanced stream includes enhanced information that when combined with the base stream re-constructs the first format. During encoding, the enhanced stream may be encoded using spatial information related to the base information stream. An output stream of the encoded base stream and encoded enhanced stream may be interleaved, concatenated, or include independent files for the encoded base stream and the encoded enhanced stream.
