摘要： The present invention relates to techniques for authentication of data streams. Specifically, the invention relates to the insertion of identifiers into a data stream, such as a Dolby Pulse, AAC or HE AAC bitstream, and the authentication and verification of the data stream based on such identifiers. A method and system for encoding a data stream comprising a plurality of data frames is described. The method comprises the step of generating a cryptographic value of a number N of successive data frames and configuration information, wherein the configuration information comprises information for rendering the data stream. The method then inserts the cryptographic value into the data stream subsequent to the N successive data frames.
摘要翻译：本发明涉及用于认证数据流的技术。具体地，本发明涉及将标识符插入诸如杜比脉冲，AAC或HE AAC比特流之类的数据流，以及基于这些标识符的数据流的认证和验证。描述了一种用于对包括多个数据帧的数据流进行编码的方法和系统。该方法包括生成连续数据帧的N个密码值和配置信息的步骤，其中配置信息包括用于呈现数据流的信息。然后，该方法在N个连续数据帧之后将密码值插入到数据流中。
