Abstract: Embodiments of the present invention provide a method, system and computer program product for multi-variable challenge-response. In an embodiment of the invention, a method for multi-variable challenge-response can include receiving a request to access content from an end user computing device from over a computer communications network. The method also can include selecting different objects for inclusion in an object set and applying a different characteristic to each of the different objects in the object set. A question and answer can be generated based upon each of the different characteristics. Further, a challenge-response prompt can be transmitted to the end user computing device such that the prompt includes the different objects with different characteristics applied, and also the generated question. A response to the challenge-response prompt can be received and compared the response to the computed answer.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to video scaling and compression and provide a novel and non-obvious method, system and computer program product for pre-distribution image scaling for screen size. In one embodiment of the invention, a compressed video delivery method can be provided. The method can include determining a display size for a target computing platform, pre-scaling video imagery to comport with the display size of the target computing platform, compressing the pre-scaled video imagery, and transmitting the compressed, pre-scaled video imagery to the target computing platform over a computer communications network.

Abstract: Merging a codec with a digital media file, including receiving, by a digital media provider from a playback device through a data communications network, a request for the digital media file, the digital media file comprising digital media content encoded by a codec, identifying, by the digital media provider, the codec by which the digital media content was encoded, inserting, by the digital media provider, the codec into the digital media file, distributing the digital media file with the inserted codec to the playback device through the data communications network. Playing a digital media file on a playback device, including receiving the digital media file in the playback device, extracting the codec from within the digital media file, installing, by the playback device, the codec for operation on the playback device, and decoding, by the playback device through the codec, the digital media content for playback on the playback device.
