A Survey on Video Watermarking Method for Reliability and Security in Video Using Least Significant Bit
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
Digital watermarking techniques have fastest growing techniques for copyright protection and authentication. Digital watermarking field has so many articles which covers innovative approach. Hence, watermarking is a solution for patent protection and content verification mechanisms. Watermarking is classified into three domain i.e. spatial, transform and wavelet. Todays media use watermarking techniques for various applications such as copyright protection, copy control and tamper recurrence. Main focus involved in watermarking approach is its design considerations, choice of suitable watermarking methodology, security, reliability and robustness. In this survey we have studied and analyze much number of techniques and methodologies where we found video watermarking interesting. In this digital world many revolution has taking place with the paradigm of multimedia distribution. Computer networks with High speed in World Wide Web have revolutionized. Distribution and production of High quality copies of digital data through the internet by exploiting recent network and software technologies. Video piracy has become an increasing problem particularly with the proliferation of media sharing through the advancement of Internet services and various technologies. Security techniques that are based on security techniques only provide assurances for data confidentiality, authenticity, and integrity during data transmission through a public channel. However, many security techniques do not provide protection against unauthorized copying or transmitting of illegal materials. Digital watermarking is the act of hiding a message related to digital signals in different forms like an image, song, video within the signal itself. Using digital watermarking, copyright information can be implanted into the multimedia data by using some algorithms. Watermark information is mainly for protecting the copyright, covert communication and data file authenticity. Existing video watermarking techniques are divided into different categories Spatial, Transform and Pixel as shown in Fig1.
