Securing Java through software watermarking

An important advantage of Java is its portability due to its use of byte ode. However the use of byte ode allows de ompilation of Java programs to gain a ess to their sour e ode. This makes it easier to pirate Java programs, infringing their opyright. This is a disadvantage of Java in omparison with programming languages that ompile to native obje t ode. Software watermarking is a relatively new approa h to the problem of opyright prote tion that involves embedding ownership information in an exe utable program. Watermarking has been extensively resear hed in the ontext of multimedia and signi ant progress has been made toward the development of robust and se ure te hniques. In this paper we investigate a new software watermarking s heme. This is derived from signal dete tion theory whi h is used in multimedia watermarking.
