pdfprivacy

Creating pdfs with pdfLaTeX populates several pdf meta-data fields such as date/time of creation/modification, information about the LaTeX installation (e.g., pdfTeX version), and the relative paths of included pdfs.
The pdfprivacy package provides support for emptying several of these pdf meta-data fields as well as suppressing some pdfTeX meta-data entries in the resulting pdf. [ctan.org/pkg/pdfprivacy]

使用pdfLaTeX创建pdf文件会填充多个pdf元数据字段，例如创建/修改的日期/时间、关于LaTeX安装的信息（例如pdfTeX版本）以及包含的pdf的相对路径。
pdfprivacy包提供了对这些pdf元数据字段进行清空的支持，以及在生成的pdf中抑制一些pdfTeX元数据条目的功能。 [ctan.org/pkg/pdfprivacy]
