This invention relates to a system and method for managing media rights. The invention provides a way to protect analogue or digital media from unlicensed distribution. This is done by means of embedding digital money (specifically, the private key of a cryptocurrency such as Bitcoin) into the media itself. If a consumer distributes the media entrusted to him, the embedded money (e.g. his deposit) risks being lost and the activity traced.
Content owners and distributors such as
Online entertainment providers
Unlike other digital rights management systems, this invention can place a direct cost to the user if he loses control of the media. Also, the moment an adversary extracts the digital money from the media, this activity (and the identity of the user) becomes visible in the cryptocurrency’s public ledger. This allows content providers to rapidly react on unlicensed distribution.
The use of unique properties of cryptocurrencies to protect media by using two properties of cryptocurrencies.
Firstly, that digital money can be embedded inside the media, but only be spent once by an adversary.
Secondly, that such activity becomes public and the user becomes tracable as soon as the digital money is spent.
When a user wishes to rent/purchase media from a content provider, the provider generates (or re-uses) a public and private key associated with the cryptocurrency, transfers money to the address, and embeds the private key in the media before providing it to the user. The block chain is then monitored for spending by an adversary.
