    • Electronic circuitry includes an input/output (I/O) interface, memory which stores a set of database fingerprints generated from records of a database, and an analyzing circuit coupled to the I/O interface and the memory. The analyzing circuit is constructed and arranged to derive a set of sample tokens from electronic data under test (e.g., an email, an electronic document, etc.), and form a set of sample fingerprints from the set of sample tokens. Each sample fingerprint is based on a sample token of the set of sample tokens. The analyzing circuit is further constructed and arranged to output a result signal based on a comparison between the set of sample fingerprints and the set of database fingerprints. The result signal provides an indication of whether the electronic data under test includes particular information from the database.
    • 电子电路包括输入/​​输出(I / O)接口,存储从数据库的记录产生的一组数据库指纹的存储器和耦合到I / O接口和存储器的分析电路。 分析电路被构造和布置成从被测试的电子数据(例如,电子邮件,电子文档等)导出一组样本标记,并从该组样本令牌形成一组样本指纹。 每个样本指纹都是基于一组样本令牌的样本令牌。 分析电路进一步构造和布置成基于样本指纹集与数据库指纹集之间的比较来输出结果信号。 结果信号提供被测电子数据是否包含来自数据库的特定信息的指示。
