2. ABSTRACT :
 To protect a VLSI design against IP infringement is by embedding a signature
 An active approach to protect a VLSI design against IP infringement is by embedding a
signature that can only be uniquely generated by the IP author into the design during
the process of its creation.

4. INTRODUCTION :
WATERMARK:
 This is science of embedding copyright information in original files .The information
embedded is called watermark
 Digital Watermarks are may be used to verify the authenticity.
 It is prominently used for tracing copyright infringements .

5. WATERMARKING:
There are 2 types of watermarking
• Static Watermarking
• Digital Watermarking

6. STATIC WATERMARKING
Design

Constraints
Blackbox Optimizer

Watermarked Design

7. Existing System & DRAWBACKS
EXISTING SYSTEM :
 Static watermarking
 To detect the output without protected design
DRAWBACKS:
 Not suitable for large design
 More time to detect Watermark bits

8. PROPOSED System
 Dynamic /Digital watermarking
 The watermark is embedded in the state transitions of FSM at the behavioral
level
 Robust against state reduction attacks.
 In this System it takes less time to detect watermark bits for implementation

9. DIGITAL WATERMARKING

10. GENERATION OF WATERMARK SEQUENCE
 Message, is first encoded into a binary string and then encrypted by a
provable cryptographic algorithm with the secret key of the IP owner
We use Secure Hash algorithm and Pseudo random generator to create a
watermark.

11. SOFTWARE REQUIREMENTS
• VERIFICATION TOOL
• MODELSIM 6.4C
• SYNTHESIS TOOL
• XILINX ISE 9.1

12. WATERMARK INSERTION

13. WATERMARK DETECTION BY USING ROBUST
FSM

14. ADVANTAGES
 The proposed watermarking scheme is robust against state reduction attacks.
 It is different from other transition based embedding methods in that it has lower
embedding overhead and has overcome the vulnerability of auxiliary inputs.
 Watermark bits can be detected by FSM easily and it can be implemented in VLSI
Design

15. APPLICATIONS
 The watermark should be able to withstand after normal signal processing operations
such as image cropping, transformation, compression.
 Depending on the ability of the watermark to withstand normal signal processing
operations, digital watermarking can be categorized as robust, fragile and semi-fragile
watermarking.
 Robust watermarks are detectable even after some image processing operations has
been performed on the watermarked image such as image scaling, bending, and
cropping, and so on. Robust watermarks are mainly used for copyright protection.

16. FUTURE ENHANCEMENT
• The copying of digital content without quality loss is not so difficult. Due to this, there
are more chances of copying of such digital information. So, there is great need of
prohibiting such illegal copyright of digital media.
• Digital watermarking (DWM) is the powerful solution to this problem.
• Digital watermarking is nothing but the technology in which there is embedding of
various information in digital content which we have to protect from illegal copying.
• Digital watermarks are of different types as robust, fragile, visible and invisible.
Application is depending upon these watermarks classifications.

17. CONCLUSION
 The proposed method offers a high degree of tamper resistance and provides an
easy and noninvasive copy detection.
 The FSM watermark is highly resilient to all conceivable watermark removal
attacks.
