document authenticity

Document authenticity refers to the assurance that a document is genuine and created or issued by the claimed source. It involves verifying that the document has not been tampered with, forged, or altered, and that its origin can be trusted. Techniques such as digital signatures, official seals, watermarks, and secure certification are used to confirm authenticity. Ensuring document authenticity is crucial for legal, financial, and official purposes to prevent fraud and establish credibility, helping everyone trust that the information or approval it contains is legitimate and valid.
