A method and system of detecting unauthorised use of content comprises comparing a first information from first electronic content to a second information from second electronic content. The first and second information may be identifying information such as a watermark, fingerprint or other mark/identifier. The content may be audio, video or computer software. If the first and second information do not match, then action such as restricting access to the first and/or second content is implemented; the first and/or second content may also be deleted. Alternatively, if there is a match between the first and second content and they are accessed at the same time, from different devices, or from different locations within a certain time period then restrictive action may again be taken. This is a digital rights management system to enforce copyright protection. If a users device A contains content 111/114 having more than one different identifier 112/115 (indicating more than one users content), then it is assumed that the user has copied content from another user and copyright infringement has taken place. |
