Information on documents can be changed in a number of ways. It can change through aging, accidental damage or as an intentional act. Changes can affect the purpose or value of a document.

Erasures, obliterations or alterations occur regularly. Information is masked or removed, and potentially replacing with new entries.

Typically, erasures occur by either physical or chemical means, removing, or partially removing entries.

Obliterations can hide original entries, occurring with the use of ink, correction fluid, photographs or a secondary document, such as a visa label in a passport.

Alterations can change the meaning or value of a document. Handwriting, printed text or security devices on a document can all be altered. Alternatively the document could be altered, such as through the effects of fire or water immersion.

Through detailed examination, using magnification and a variety of lights sources and filters, entries can be enhanced or recovered, or alterations shown.

Occasions where this type of examination may be conducted include passports and identity documents, entries in journals or diaries, employment references, educational qualifications or financial records.
