Towards a Conceptual Framework for Digital Contract Composition and Fulfilment

In this paper we introduce a new image watermarking algorithm based on modified spread spectrum methods to improve data payload and the associated system architecture for semifingerprinting. The proposed watermarking method makes to increase data payload using the random number shift (RNS). A mount of embedding data is 60bits of real data and 20bits of Cyclic Redundancy Check (CRC) to improve the accuracy. For semi-fingerprinting, we applied data structure of
