Video Source Identification Algorithm Based on 3D Geometric Transformation

Video Source Identification Algorithm Using Gaussian-based Sensor Pattern Noise

Multimedia such as image, audio, and video is easy to create and distribute with the advance of IT. Since novice uses them for illegal purposes, multimedia forensics are required to protect contents and block illegal usage. This paper presents a multimedia forensic algorithm for video to identify the device used for acquiring unknown video files. First, the way to calculate a sensor pattern noi...

A chaos-based video watermarking algorithm

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

A Novel Source MPEG-2 Video Identification Algorithm

With the availability of powerful multimedia editing software, all types of personalized image and video resources are available in networks. Multimedia forensics technology has become a new topic in the ̄eld of information security. In this paper, a new source video system identīcation algorithm is proposed based on the features in the video stream; it takes full advantage of the di®erent chara...

3D geometric metamorphosis based on harmonic map

Recently, animations with deforming objects are frequently used in various Computer Graphics applications. Metamorphosis (or morphing) of three dimensional objects is one of techniques which realize a shape transformation between existing two or more objects. We present a new algorithm for 3D geometric metamorphosis between two objects based on Harmonic Map. Our algorithm is applicable for arbi...
