CET has been granted a patent for the invention of a method and user terminal for determining the authenticity of videos. This can be used for detecting forged videos which has promising applications in providing trustworthiness of videos in legal investigations, police investigations, and medical diagnosis which use videos as confirmative evidence.
With the use of cell phones, camcorders, security cameras, and other digital imaging devices, enormous amounts of video data are generated every instant. Anyone can alter video footage to their desire easily using the any one of the abundant video editing tools available today. They can be produced for nefarious ends that pose serious risks to individuals, organizations, and even national security. This ultimately results in ”seeing is no longer believing”.
The invention helps to verify integrity of video data and detect any type of forgery at any point of time by anyone on any type of video file in a faster and more secure way using blockchain technology, digital signature algorithm and cryptographic hash function with 100 percent accuracy. This invention can be integrated to any imaging devices like digital cameras, mobile phones, accident recorders and surveillance camera for generating videos, the authenticity of which can be verified at any point of time. This can also do tamper localization up to segment level.
The research work that led to this invention was carried out in the Computer Science and Engineering department of CET by Linju Lawrence, PhD research scholar in Computer Science and Engineering department of CET (Lecturer in Computer Engineering, Govt. Polytechnic College, Cherthala) under the guidance of Dr. Shreelekshmi R, former SPFU director, Directorate of Technical Education and Professor in the Computer Science and Engineering department of Marian Engineering college, Thiruvananthapuram.
