Dish Network to Patent Blockchain Anti-Piracy System

The system will allow owners to embed an id mark in a content code that can be stored and  updated using a blockchain

One of the largest US television providers has filed a patent application for a new “anti-piracy system” on the blockchain, allowing content owners to track its use.

The Dish Network patent application describes a system that allows owners to embed an identification mark in a content code that can be stored and regularly updated using a distributed ledger. Dish says the system will help better monitor and enforce property rights by warning platforms when their materials are used without permission.

According to the application, one of the main problems with Internet streaming of streaming video is that it is becoming increasingly difficult to combat piracy. Video owners find it difficult to track a large number of distribution platforms. Although pirated content can be quickly removed after being discovered, at this point videos are often viewed more than a million times.

Dish Network’s anti-piracy system will use blockchain to embed content owner data in code. Only copyright holders will be able to download and update this data. In addition to serving as a means to more effectively verify copyright, the system is also able to help online streaming platforms, enforce property rights, and take action against pirated videos.

Based on the application, it is not clear whether the Dish Network proposed anti-piracy system will work on its own blockchain or on an existing platform. The system also allows video distributors to buy content directly from owners. Users will be able to pay owners in fiat currencies or crypto assets, and in return will be able to receive unique identification tokens that allow them to use the content.

Identity tokens can be customized to give distributors access for a limited time or the ability to edit videos on specific platforms. If the distributor does not have the appropriate access rights, the system can automatically notify the owner of the materials that they are used without permission.

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system

Technology security firm Least Authority, at the request of the Ethereum Foundation, conducted an audit of the Ethereum 2.0 specifications and identified several potential vulnerabilities at once.

Least Authority said that developers need to solve problems with vulnerabilities in the network layer of peer-to-peer (P2P) interaction, as well as in the block proposal system. At the same time, the auditor noted that the specifications are "very well thought out and competent."

However, at the moment there is no large ecosystem based on PoS and using sharding in the world, so it is impossible to accurately assess the prospects for system stability.
Also, information security experts emphasized that the specifications did not pay enough attention to the description of the P2P network level and the system of records about Ethereum nodes. Vulnerability risks are also observed in the block proposal system and the messaging system between nodes.

Experts said that in the blockchains running on PoS, the choice of a new block is simple and no one can predict who will get the new block. In PoS systems, it is the block proposal system that decides whose block will fall into the blockchain, and this leads to the risk of data leakage. To solve the problem, auditors suggested using the mechanism of "Single Secret Leader Election" (SSLE).

As for the peer-to-peer exchange system, there is a danger of spam. There is no centralized node in the system that would evaluate the actions of other nodes, so a “malicious" node can spam the entire network with various messages without any special punishment. The solution to this problem may be to use special protocols for exchanging messages between nodes.
