Secure Content Testing (SCT) is Touchstone’s proprietary visual and forensic watermarking security technology for protecting content in marketing research and consumer insights studies. SCT works by applying a unique visual and forensic watermark to content within a quantitative survey or qualitative research study that can be used to tie the content back to the individual research participant. This provides an extremely effective technique for deterring respondents from sharing content as any compromised content can be used to identify the person who shared it.
