An internet-based IP protection scheme for circuit designs using linear feedback shift register (LFSR)-based locking
TLDR
The proposed scheme makes unauthorized disclosure of valuable design almost infeasible, and can easily detect any alteration of the design file during transmission, and ensures authentication of the original designer as well as non-repudiation between the seller and the buyer.Abstract:
IP reuse is rapidly proliferating recent automated circuit design. It is facing serious challenges like forgery, theft and misappropriation of intellectual property (IP) of the design. Thus, protection of design IP is a matter of prime concern. In this paper, we propose a novel Internet-based scheme to tackle this problem. Input to the proposed scheme is a graph corresponding to a digital system design. Watermarking of the graph and its encryption are achieved using a new linear feedback shift register(LFSR)-based locking scheme. The proposed scheme makes unauthorized disclosure of valuable design almost infeasible, and can easily detect any alteration of the design file during transmission. It ensures authentication of the original designer as well as non-repudiation between the seller and the buyer. Empirical evidences on several benchmark problem sets are encouraging.read more

A persistent public watermarking of relational databases
Raju Halder,Agostino Cortesi +1 more
TL;DR: A novel fragile and robust persistent watermarking scheme for relational databases that embeds both private and public watermarks where the former allows the owner to prove his ownership, while the latter allows any end-user to verify the correctness and originality of the data in the database without loss of strength and security.
Persistent Watermarking of Relational Databases
Raju Halder,Agostino Cortesi +1 more
TL;DR: This paper proposes a novel persistent watermarking scheme that strictly improves the algorithm proposed by Li and Deng and preserves the persistency of the watermark by exploiting two invariants of the database state w.r.t. the set of queries.
