Video Rewrite uses existing footage to create automatically new video of a person mouthing words that she did not speak in the original footage. Video Rewrite uses computer-vision techniques to track points on the speaker’s mouth in the training footage, and morphing techniques to combine these mouth gestures into the final video sequence. The new video combines the dynamics of the original act...

certificateless public key cryptography (cl-pkc) is a useful method in order to solve the problems of traditional public key infrastructure (i. e. large amount of computation, storage and communication cost for managing certificates) and id-based public key cryptography (i. e. key escrow problem), simultaneously. a signcryption scheme is an important primitive in cryptographic protocols which p...

As a new cyber-attack method in power cyber physical systems, false-data-injection attacks (FDIAs) mainly disturb the operating state of systems by tampering with measurement data sensors, thereby avoiding bad-data detection grid and threatening security systems. However, existing FDIA methods usually only focus on feature extraction between false normal data, ignoring correlation that easily p...

Libsafe is a practical solution that protects against the most common forms of buffer overflow attacks. Such attacks often result in granting the attacker full privileges on the target system. Libsafe is implemented as a shared library that intercepts calls to vulnerable standard library functions. Based on an inspection of the process stack and the function arguments, Libsafe ensures that no r...
