    摘要: Methods and systems of distributing digital content governed by a digital license are provided. In one aspect, the license has identification data for licensed content and is transmitted to a client device. A first item of content is transmitted to the client after receipt by the client of the license. The first item of content has first content identification data, and at least a portion of the first item of content is in encrypted form. A second item of content is transmitted to the client after receipt by the client of the license. The second item of content has second content identification data that is different from the first content identification data. At least a portion of the second item of content is in encrypted form. The encrypted portion of the first item of content is decrypted if the first content identification data corresponds to the identification data for licensed content. Similarly, the encrypted portion of the second item of content is decrypted if the second content identification data corresponds to the identification data for licensed content. The identification data for licensed content remains unchanged after the license is transmitted to the client.

    摘要: A license evaluation apparatus and method is disclosed which can specify the substance and the position of an error only with a simple description without the necessity to analyze the error in an ex post fact fashion. A data storage section stores licenses, and a content selection section selects a content. A license extraction section extracts the license from within the data storage section. A conditional expression decision section reads a conditional expression in use condition information of the license and an error code annexed in advance to the conditional expression and deciding whether or not the conditional expression is satisfied. If the conditional expression is not satisfied, an error code retaining section retains the error code. An application to which the error code is returned can specify the error without analyzing the error in an ex post fact fashion.
