Wacom

Wacom offers Yuify, a service that embeds an invisible digital watermark into artwork files so artists can prove they created a piece and control who uses it. The open beta launched in November 2024 and works as a plugin inside popular image-editing apps including Photoshop and Clip Studio Paint.

Wacom Yuify uses proprietary micromarking technology to inject invisible pixels into JPEG or PNG images during export. The export event is recorded on a decentralized blockchain, creating a permanent, tamper-proof proof-of-authorship record. A companion tool called Yuifinder lets anyone drag and drop an image to check whether it has been registered and who created it. Artists can also use a License Builder tool to set reuse terms, stored permanently on the blockchain. The service was publicly launched in open beta on November 15, 2024 at the Connected Ink 2024 event in Tokyo.

Wacom tested a proof-of-concept system with the German Research Center for Artificial Intelligence (DFKI) that uses AI to analyze handwritten notes created on Wacom tablets, identify the meaning of text and drawings, and automatically surface relevant information from a knowledge base. This was publicly demonstrated in late 2018 and remains part of Wacom's stated vision for its digital ink platform.

The system uses Wacom's WILL (Wacom Ink Layer Language) framework combined with DFKI's CoMem knowledge management system. AI classifies each pen stroke as handwritten text, a hand-drawn diagram, or a doodle, then performs named entity recognition on the text to identify dates, contacts, topics, and other entities. It then proactively retrieves and presents related information — such as meeting dates, contact details, or related documents — from a personal or enterprise knowledge graph. The proof of concept was publicly demonstrated at the Samsung Developer Conference in November 2018. As of the most recent sources, this remains a research and platform-level capability rather than a shipping end-user product.

Wacom offers the Wacom Ink SDK for Verification, a software toolkit that organizations integrate into their document systems to automatically verify whether a handwritten electronic signature matches a registered reference, producing an instant accept/reject score in real time.

The verification engine compares a new handwritten e-signature against up to six stored reference signatures, analyzing biometric data including pen position, pressure, inclination, and speed of movement. It generates a similarity score between 0 and 1; the organization's workflow owner sets the acceptance threshold. The SDK is designed for real-time use at the point of signing and does not store signature data after verification, which Wacom states eliminates compliance issues. It is offered as a licensed SDK for integration by third-party solution providers into banking, healthcare, and other document-centric workflows.
