Abstract: A characteristic thumbprint is extracted from a data signal, the thumbprint based on statistics relating to the data signal. The data signal can be compared indirectly by matching this thumbprint against one or more reference thumbprints. The data signal may be any type of signal, including streaming digitized audio or obtained from static files. A database may contain a number of these characteristic thumbprints, and the database can be searched for a particular thumbprint.

Abstract translation: 从数据信号提取特征指纹，基于与数据信号有关的统计量的指纹。 可以通过将该指纹与一个或多个参考指纹匹配来间接地比较数据信号。 数据信号可以是任何类型的信号，包括流式数字化音频或从静态文件获得。 数据库可以包含许多这些特征指纹，并且可以搜索数据库以获得特定的指纹。
