Abstract
In this paper, a spatial domain approach of fingerprinting is presented for colored digital images. A semi-blind fingerprinting conveys a secure arrangement for trading of digital images. The operational significance of the digital fingerprinting system is verified and estimated. Digital fingerprint implanted doesn’t disturb the perceptible feature of the host digital image. Multi-user collusion attacks are prevented using the proposed apparoach. Variable fingerprint size and dissimilar location insertion play significant role for inhibiting attack.

To identify each listed buyer and collusion attackers of a number of listed users, dissimilar size digital fingerprint is set into the identical digital image for all legal listed buyers
Summary
Request for shielding intellectual possession of digital content is augmenting due to rise in crime escalation. The rise is allied with a prompt expansion of information technology and its organization. A massive amount of digital content have been copied. Digital fingerprinting using watermarking technique is one of the effective methods to defend digital content for content exchange. Fingerprinting is a system that is castoff for finding illegitimate manipulators [1]. In this modus operandi, a unique identification number is inserted into content afore delivery. When a doubtful replica of the content is instituted, an owner can ascertain an illicit user by mining the fingerprint
