Watermarking for intellectual property protection - Electronics Letters
نویسندگان
چکیده
A new watermarking method for intellectual property (IP) protection is presented. The proposed method uses a uniquely generated stream of bits, known as a watermark, embedded into the self-test circuit to represent ownership. This scheme can detect the ownership rights of the IP provider even when the chip has been packaged. Experimental results show the proposed embedding technique can survive synthesis, placement and routing. The experimental results are given to demonstrate the proposed method.

However, many of these techniques share two specific we...
متن کاملIntellectual Property Protection Using Watermarking Partial Scan Chains for Sequential Logic Test Generation
We propose a protocol for intellectual property protection by watermarking the selection of register scan chain during the sequential logic test generation design-for-test step. The watermark, a user-specific digital signature, is embedded into the design by restricting and/or forcing specific registers to appear in the chain of scan registers. Therefore, selection enforcement is enabled by imp...
