Abstract
Abstract. Portable Document Format (PDF) is one type of file that is frequently exchanged over the internet. Proving ownership of PDF documents is important so that they are not used by irresponsible people. So that proof of ownership of PDF documents can be done, this research proposes applying digital signatures. Digital signatures are generally inserted in the body in the internal structure of the PDF. In this research try to insert a digital signature in the xref pdf section. Before the copying process is carried out, the Digital signature is compressed first with the Huffman algorithm to optimize data storage capacity in each xref line and the inserted data is not easily perceived. The experimental results in the study showed that the size of the digital signature data that had been compressed using the Huffman algorithm decreased by an average of around 16.25% compared to before it was compressed. Digital signature data entered in the xref section is not easily perceived and does not increase the size of the pdf file. Keywords: Digital Signature, Huffman, PDF.
