AbstractDigital document image is a form of persevering important information, and, because of rapid technological development, it is easy to copy, counterfeit this digital document image and claim ownership. Therefore this paper presents a document image authentication scheme based on using secret sharing that can:
1.Authenticate document image.
2.Verify the owner of the document image.
3.Localize the alteration in the document image.
4.Detect the error in the document image, and
5.Correct the error in the document image.
According to comparison of different document image authentication methods, there is no distortion in stego image, the method has capability to locate the tampering, repair capability, reported authentication precision for each (2X3) block, distribution of authenticated image parts in the entire image and manipulating data embedding in LSB(least Signification Bit).
