Abstract: The secure circulation of digital documents to be reproduced includes providing each user with a smart card containing identification information associated therewith, and identifying from a server connected to a digital data transmission network the smart card connected thereto. Information identifying a document to be played back is transmitted to the server from a terminal connected to the smart card. In response, a decryption key specific to the document to be reproduced is transmitted to the smart card for storing therein. The document to be played back is decrypted using an adapted reader connected to the smart card, and includes the stored decryption key for document playback with the reader. Information identifying the readers is inserted into the smart card, and fraudulent use of the smart card is determined according to the reader identification information stored in the smart card.

Abstract translation: 要再现的数字文档的安全流通包括向每个用户提供包含与其相关联的识别信息的智能卡，以及从连接到数字数据传输网络的服务器识别连接到其上的智能卡。 识别待播放文件的信息从连接到智能卡的终端发送到服务器。 作为响应，将要被再现的文档特定的解密密钥发送到智能卡以用于存储。 使用连接到智能卡的适配读取器对要播放的文档进行解密，并且包括用于与读取器进行文档回放的所存储的解密密钥。 将识别读取器的信息插入到智能卡中，并且根据存储在智能卡中的读取器识别信息确定智能卡的欺诈性使用。
