| 20100306552 | SYSTEMS AND METHODS FOR PREVENTING UNAUTHORIZED USE OF DIGITAL CONTENT - Theft, distribution, and piracy of digital content (software, video, audio, e-books, any content of any kind that is digitally stored and distributed) is generally accomplished by copying it, if possible, or, if it is protected from being copied in any fashion, such piracy is based upon a number of reverse engineering techniques. Aside from the straightforward copying of unprotected content, all of these other methods require first an understanding of the protective mechanism(s) guarding the content, and finally an unauthorized modification of that protection in order to disable or subvert it. Methods that prevent a skilled individual from using reverse engineering tools and techniques to attain that level of understanding and/or prevent anyone from performing such modifications can offer significant advantages to content creators who wish to protect their products. | 12-02-2010 |
| 20100165812 | SYSTEMS AND METHODS FOR MEDIA AUTHENTICATION - A method and system for authenticating a digital optical medium, such as a CD-ROM, determine whether the medium is an unauthorized copy, or the original. The original media is created, or altered, so as to contain anomalous locations from which the transfer of data is accomplished at different rates than a standard digital copy would exhibit. One implementation of the process involves timing analysis of the differences in data transfer rates. Another implementation involves the determination of digital signatures during multiple read operations performed on a data segment. The process can be employed in systems that control access to unauthorized copies, or may be used for other informative purposes. Theft, distribution, and piracy of digital content on optical media, such as computer software (also games, video, audio, e-book content), is often accomplished by copying it directly to another disc using commonly available copy tools and recordable optical media, or the replication of media to another mass manufactured disc. The present invention, which helps to irrefutably identify a unit of optical media as the original, and can correspondingly identify any copy made by any currently available means as such a copy, may prevent an unauthorized individual from making use of any unauthorized copies. This offers significant advantages to content creators who wish to protect their products. | 07-01-2010 |
