Abstract: With the rapid growth of information and communication technology, the need for a sophisticated digital forensic approach to security has become more urgent. The problem that needs to be resolved using digital forensic steps is the indication of alteration and falsification of documents with the .pdf extension. By involving various forensic analysis methods, such as metadata examination, physical observation, hash value, analysis using Principal Component Analysis (PCA), and the use of forensic tools such as Adobe Acrobat Reader, Exiftools, imageforensic.org and HashMyFile, it is expected to address existing crime cases. This research aims to study the challenges posed by digital documents, emphasizing the need for innovative approaches to uncover hidden information, detect alterations, and authenticate the integrity of PDF files. The combination of the NIJ method and Analysis using PCA produces an accurate and precise analysis as seen from the dimensionality reduction capability of PCA. The results show that the NIJ method and PCA analysis can be used to prove the authenticity of a PDF document by finding changes in the PDF document. In addition, this research also provides recommendations for the development of forensic techniques in supporting the reliability and security of digital documents. It is hoped that this research can make a valuable contribution to the development of forensic techniques.
