16. **Document Scanner**: A Document Scanner is a device used to create digital copies of documents for analysis and comparison. It can capture high-resolution images of security features and text for authentication purposes.

17. **Forensic Analysis**: Forensic Analysis involves the scientific examination of physical evidence to uncover information relevant to a legal case. In the context of document authentication, forensic analysis may include ink analysis, paper analysis, and handwriting analysis.

18. **Counterfeit**: A Counterfeit is a fake or imitation of a genuine document created with the intent to deceive. Counterfeit documents often lack security features and exhibit signs of forgery.

19. **Forgery**: Forgery is the act of creating or altering a document with the intent to deceive others. Forged documents may contain false information or unauthorized signatures and can be detected through careful examination.

20. **Tampering**: Tampering refers to the unauthorized alteration of a document to conceal or change information. This may involve erasing or modifying existing text, signatures, or seals to create a fraudulent document.

21. **Altered Document**: An Altered Document is a genuine document that has been modified or tampered with to change its content or appearance. Detecting altered documents requires careful examination of inconsistencies and irregularities.

22. **Document Examination**: Document Examination is the process of analyzing documents to determine their authenticity, integrity, and origin. This involves comparing known standards and characteristics to identify signs of fraud or tampering.

23. **Exemplar**: An Exemplar is a genuine document used as a reference for comparison during document examination. Exemplars help analysts identify discrepancies and inconsistencies in questioned documents.

24. **Questioned Document**: A Questioned Document is a document whose authenticity or authorship is in doubt. Questioned documents may be suspected of being forged, altered, or tampered with and require careful examination to determine their validity.

25. **Handwriting Analysis**: Handwriting Analysis is the study of handwriting characteristics to identify the author of a document. This technique is used to determine whether a signature or handwritten text is genuine or forged.

26. **Ink Analysis**: Ink Analysis involves examining the chemical composition of ink used in a document to determine its age, origin, and authenticity. Different inks may fluoresce under UV light or exhibit unique properties that can help detect forgeries.

27. **Paper Analysis**: Paper Analysis is the study of paper composition, texture, watermark, and other characteristics to determine the authenticity of a document. Different types of paper may indicate the document's age, origin, or manufacturing process.
