Document verification is the process of confirming the authenticity and accuracy of documents. This can include checking identification cards, passports, or financial statements to ensure they are legitimate and not forged. Organizations often use this process to prevent fraud and ensure compliance with legal requirements. The verification process typically involves comparing the document against official records or using specialized software to detect alterations. It is commonly used in various sectors, including banking, immigration, and employment, to protect against identity theft and ensure that individuals are who they claim to be.
