Compute Resources 6.1 Main Findings: All Protections are Easily Circumvented We find that all existing protective tools create a false sense of security and leave artists vulnerable to style mimicry. Indeed, our best robust mimicry methods produce images that are, on average, indistinguishable from baseline mimicry attempts using unprotected art. Since many of our simple mimicry methods only use tools that were available before the protections were released, style forgers may have already circumvented these protections since their inception. Noisy upscaling is the most effective method for robust mimicry, with a median success rate above 40% for each protection tool (recall that 50% success indicates that the robust method is indistinguishable from a mimicry using unprotected images). This method only requires preprocessing images and black-box access to the model via a finetuning API. Other simple preprocessing methods like Gaussian noising or DiffPure also significantly reduce the effectiveness of protections. The more complex white-box method IMPRESS++ does not provide significant advantages. Sample generations for each method are in Appendix B. A style forger does not have to use a single robust mimicry method, but can test all of them and select the most successful. This “best-of-4” approach always beats the baseline mimicry method over unprotected images (which attempts a single method and not four) for all protections. Appendix A shows images at each step of the robust mimicry process (i.e., protections, preprocessing, and sampling). Appendix B shows example generations for each protection and mimicry method. Appendix C has detailed success rates broken down per artist, for both image style and quality. Authors:
