Abstract: Improved techniques for video watermarking are described. In one embodiment, for example, an apparatus may comprise a processor circuit and a watermarking module for execution by the processor circuit to generate disabled video content through modification of a video content item, send a common stream comprising the disabled video content, and send a private content key for the disabled video content, the private content key defining a watermark for the video content item. Other embodiments are described and claimed.

Abstract: A method of protecting a broadcast frame, the method comprising broadcasting a beacon and a maintenance beacon frame (MBF) from an access point (AP) to a plurality of terminals during a maintenance beacon waiting period (MBWP); and broadcasting broadcast management frames (BMFs) from the AP to the plurality of terminals during a broadcast management frame waiting period (BMFWP), wherein the MBF comprises a BMFs message integrity code (MIC) field including a BMFs MIC calculated from concatenated BMFs to be sent in a current beacon interval.

Abstract: A weighted secret sharing and reconstructing method includes encoding the secret using a predetermined code, producing voices so that different weights are assigned to errors in an error vector according to locations of the errors, encrypting the encoded secret using the error vector and distributing the encrypted encoded secret to a plurality of participants.

Abstract: A combination encoding method, a transmitting apparatus thereof, a combination decoding method, and a receiving apparatus thereof are provided. The transmitting apparatus includes a combination encoding unit for performing combination encoding on a source coded message and outputting the combination encoded message, thereby performing encrypting and channel encoding simultaneously. The receiving apparatus includes a combination decoding unit for performing combination decoding on the noise-added combination encoded message from the demodulator, and outputting a source coded message, thereby simultaneously performing channel decoding and decrypting on the noise-added combination encoded message.
