Genetica De Protector: Sistema Autenticidad Para Video.
Con esta noticia si siento que ya estamos en el siglo XXI y que vere cosas que parecen de ciencia ficcion, imaginen la biotecnologia y la industria cinematografica con la informatica unidas en un problema comun: Detectar las copias no autorizadas albergadas en servidores Streaming.
Pues bien, haciendo una analogia con el codigo genetico ADN y su estructura, algunos investigadores han creado un metodo para asignar una huella genetica especifica y unica para un video, con esto las copias exactas seran identificadas inmediatamente en servidores como Youtube y ser borradas de inmediato e incluso las copias transcodificadas o recodificadas seran reconocidas como "mutaciones" de la copia base o maestra con lo que igual seran detectadas como una copia no autorizada.
El sistema se llama
VIDEO DNA y que es concebido por los investigadores Dr. Alex Bronstein, Michael Bronstein, y Ron Kimmel quienes tomaron como modelo las tecnicas y sistemas de secuenciacion para identificacion del ADN. Basicamente el sistema consiste en tomar un fotograma clave cualquier -estos fotogramas son los unicvos fotogramas completos en un formato de video basado en compresion, en uno sin compresion todos los fotogramas estan compltos- cualquiera y en base a ciertos algoritmos parcelar o dividir tal fotograma para comenzar a encontrar una secuencia que sea unica e irrepetible con la cual en base a ciertos criterios se le asignara un valor numerico el cual sera "la huella genetica" que identifique uniocamente a ese fotograma y por ende a la totalidad de la pelicula.
Ingenioso y quiza no tan caro de implementar.
Jack Sparrow, ya te vi y ya te identifique y aunque te hagas la cirugia plastica no podras escoenderte.

Aside from the frequent bad quality of recordings, the film industry reckons billions are lost each year. Scientists at Tel Aviv University’s Department of Electrical engineering have looked to DNA as a means to stop the unwarranted distribution of films.
Twin brothers Dr Alex and Michael Bronstein have, alongside Israeli researcher Professor Ron Kimmel, have been attempting to develop a method of tracing video footage by creating a DNA analogue, like a fingerprint, that can be applied to every individual film on the planet.
"It's not only members of the animal and plant kingdom that can have DNA," says Dr. Bronstein, who was inspired by DNA sequencing tools used in bioinformatics laboratories. "If a DNA test can identify and catch criminals, we thought that a similar code might be applicable to video. If the code were copied and changed, we'd catch it."
The method involves employing an invisible sequence and applying a series of grids over the film. The technology is then able to turn the footage into a series of numbers. Afterwards, it's possible to scan the internet, focusing on websites where pirate films are downloaded, before pinpointing subsequent mutations of the original.
According to Dr Bronstein, when films are altered, colours changed, or the film is bootlegged in a cinema the film can then be tracked online.
The technology, dubbed ‘video DNA matching’ detects aberrations in pirated video in much the same way that a biologist is able to find mutations in genetic code, such as when determining an individual’s familial connections.
According to the researchers, the technique works by identifying features of the film that remain basically unchanged by typical colour and resolution manipulations, and geometric transformations.
It is also noted that the technology is still effective even with commercials added in, border changes and even with scenes edited out.
The researchers believe that the technology will have useful applications with regards to user generated sites like YouTube - they say it automates the detection of copyright infringement to a degree, but not when the video has been altered, unlike the ‘video DNA matching’ method.
Furthermore they believe that the problem with catching pirated video is that it requires thousands of hours to watch the content being downloaded. The researchers believe that production companies’ only hope is to fully automate the process, something that video DNA matching may be able to assist with.
