Abstract
A file containing proprietary content can be protected against unauthorized duplication via file sharing between remote computers connected to an Internet swapping service. To this end, the content to be protected is searched on the Internet, at least the hash ID of each data record offered as a search hit is stored, this hash ID is linked to substitute content data, and queries of remote computers for the file to be protected are responded to by offering the modified data record.
Claims7
Method for protecting a file with proprietary content against unauthorized copying by file sharing by other people's computers which are pooled to form an internet file sharing site and which make the file available in the form of randomly stored data records, each of which includes part of the proprietary content and metadata which inter alia consist of at least one hash ID and e.g. the title, characterised by the following steps:
- searching for the content to be protected on the internet
- saving at least the hash ID of each data record provided as a hit by at least one other person's computer
- generating a data record which is modified from the data record provided and which includes at least the saved hash ID and replacement content data linked to the latter
- answering inquiries from other people's computers about the file to be protected, by providing the modified data record.
