....material that, should the integrity of the client be violated, will incur financial losses to the owner of the client. We will next consider three such scenarios. 1. 1 Malicious host attacks Software piracy, the illegal copying and resale of applications, is a 15 billion dollar per year industry [1]. Piracy is therefore a major concern for anyone who sells software. In the early days of the personal computer revolution, software developers experimented vigorously with various forms of technical protection [19, 22, 32 35, 47, 53] against illegal copying. Some early copy protection schemes ....

....and fingerprinting of software. Although much has been written about protection against software piracy [2,17 19,25,26,33] software watermarking is an area that has received very little attention. This is unfortunate since software piracy is estimated to be a 15 billion dollar per year business [3,23,24,34]. The choice of software watermarking technique will depend in part on the kind of object code we want to protect. In this paper we will assume that Alice s object O is an application distributed to Bob as a collection of Java class files. As we shall see, watermarking Java class files is at the ....

This is unfortunate since software piracy is estimated to be a 15 billion dollar per year business [3,24,25,35].
