Patent abstract
A variety of systems responsive to watermarked documents are detailed. In one, watermarking is employed to facilitate e-commerce transactions. More particularly, watermarking is employed to assure that an on-line purchaser of goods has physical custody of the credit card being charged. Without such custody, the requested transaction will be refused by the credit card issuer.
