Abstract
In one embodiment, a computer-implemented method of digitally signing input by a data processing (DP) accelerator operation, and embedding the digitally signed input into an output, includes receiving, from a host device, a signature kernel specifying input to the signature kernel and executing the signature kernel to: extract a watermark from the input and obtain a hash for the watermark; generate output from the input; and embed the hash into the output. The DP accelerator provides the output to the host device. In an embodiment, the input includes an artificial intelligence (AI) model that is executed by the DP accelerator. The DP accelerator receives second input from the host, thereby producing an inference output from the AI model. The digitally signed watermark of the AI Model is embedded into the inference output and is provided to the host device.
