What is Internet security (piracy and protection) ?

Piracy of the future: measures to protect its content

On account of the enduring development in the utilization of online video documents and the fast development of Internet-associated gadgets in the course of the most recent five years, content distributes have the unprecedented chance to exploit the Internet to contact a more extensive group of onlookers and to investigate new plans of action for their video resources. In any case, the way to this achievement lies in satisfying the legally binding commitments of the substance proprietors. Legally binding commitments may add up to the capacity of a substance merchant, for example, a telecom organization or a free gushing specialist co-op or OTT, to secure substance that is being disseminated over IP-based systems, for example, the Internet, unapproved utilize and redistribution. The reason is very basic: content robbery essentially undermines the substance distributer's capacity to adapt their important resources. Take for instance the year 2012. In 2012, the film that was most downloaded wrongfully was Project X, which was downloaded a sum of 8.7 million times. On the off chance that we take as a normal cost of 4.99 euros for every survey of an online motion picture, this would add up to 43.4 million euros in lost income, or if nothing else that is the means by which the media and media outlet sees it. The most downloaded TV arrangement in 2012 was "Session of Thrones", which was illicitly downloaded a sum of 4.3 million times. By and by, regarding a potential loss of benefits, this cost could be evaluated at 12.8 million euros, on the off chance that we go up against normal a cost of 2.99 euros for each download.Therefore, it should not surprise us that content owners consider piracy as an illegal activity equivalent to entering a store and stealing a DVD. Securing physical media in a physical store is relatively simple, but securing media assets that are distributed over IP networks is a much more complex task that requires a multilevel approach that applies different techniques to protect against different types of threats. In addition, content protection must find the right balance between legal and business requirements, end-user experience and costs. 

There are several ways that video content is compromised when it is distributed over the Internet.Attacks on video content can happen in the following ways: 

Link sharing: an unauthorized user gains access to high-value or paid content, bypassing a retailer's business model. 

Deep linking: a hacker decompiles the hidden links of players and publications to their own website in order to monetize the content. 

Player hijacking: stealing the player and then copying it to a different website, avoiding the attributions of the original site. 

Ripping of sequences (stream ripping): consists in stealing the actual content of a sequence while it is being transmitted to the client's systems. 

Stealing from cache: stealing content from a browser, the cache of a player or a disk. 

Content tampering: consists of manipulating the actual content (eg, replacing or inserting unwanted advertisements in the sequence). 

Today there are a large number of technologies available from vendors such as Akamai Technologies, Microsoft, Adobe and Google that can be used to help protect the content of most common threats against content distributed over the Internet. 

These mechanisms are designed to discourage and disable the ability to hack content, while at the same time allowing the content owner to successfully monetize their video assets, whether through "pay per view", rentals and subscriptions, ad-supported video. or other innovative business models. 

Some of these technologies include:

Authorization Token: this is a method by which a "shared secret" is exchanged and validated between the web infrastructure of the content providers and the user (connecting from their IP-enabled device). This mechanism is normally enabled to verify that the end user has access rights to the content of the provider. Token-based authorization mechanisms are commonly used on the Internet as a security measure to validate user rights. To help confirm that only authorized users have access to your video stream, the mechanism can be used.

Token authorization security to provide a hybrid token scheme that uses a combination of a TTL short URL token and a long TTL cookie-based token. 

Player verification: Player verification has been designed to prevent unauthorized players from reproducing protected content. Considering that the video player application can control much of the user's experience (eg, appearance, playback function, ad display, and security options), make sure the player is valid and has not been modified offers a high degree of security against deep link attacks that aim to circumvent the business model of the content provider. This security mechanism is designed to ensure that the player and the resident AUTH module are original. Normally, this is achieved by connecting the player and the AUTH module with a hash function to produce a digest of messages that is verified by the server that is managing the transmission of the content. In addition, the verification of the player can also include a function that allows to check the image that appears for a certain security code, and the obfuscation of the AUTH module. 

Geofencing or focalization of content: geofencing or content targeting allows to control the access to content in certain geographical regions. For example, a content provider in Germany can acquire a license for a film from large studios but that limits the distribution of that film to the German market only. The technology of geofencing or content targeting allows the content provider to limit the consumption of said video to the territory of Germany. 

Media coding: media coding is the process of encoding video content in such a way that hackers can not read it and ultimately rip it, but authorized parties can. In the case of video transmission, media encoding can be applied at multiple levels to protect the content. For example, a content provider may decide to encode only the transport layer, but not the content. For additional security, the content provider can also choose to encode the content itself, in addition to the transport layer. One of the most powerful applications of this technology is the use of key coding per session. This measure implies that each video session request has its own unique coding key. 

Digital rights management: Better known as DRM for its acronym in English, the management of digital rights is a method that consists of executing and managing the policies of video distribution.For example, a content provider could exclusively allow a video to be downloaded and available for a period of twenty-four hours after the download. The DRM would ensure that the copy of the video was not available after the expiration of that twenty-four hour period. This procedure is common in the digital video rental market. DRM could also be used to ensure that a video can only be played on the device that downloaded it, and can not be transferred to other playback devices. 

The security mechanisms described above are designed to provide content providers with tools to help protect them against theft and unauthorized use of their online video content at extended play times. Leveraging the benefits of previous technologies provides a multi-level security approach that, in most cases, can be applied easily and incrementally to avoid maintenance problems and software installation for the end user.
