SNAPTAG's Invisible Watermark

SNAPTAG's patented technology, the invisible watermark, is a technique for invisibly linking data to images/videos. It allows for distortion-free data input and easy data verification.

What is the Invisible Watermark?

The invisible watermark is a technology that involves inserting data into images or videos in a way that is not visible to the naked eye.

This hidden data can then be retrieved and read using a specialized program.

Methods to Detect Invisible Watermark

There are various methods provided to detect invisible watermark.

  • 카메라로 워터마크 스캔하여 확인

    Camera Scan for Watermark Detection

    Using a specialized camera, when you illuminate the area you wish to check, you can detect the information stored within the watermark.

    *Provision of App or SDK

  • 파일을 업로트하여 확인

    File Upload for Watermark Detection

    To detect a watermark, you upload the file you want to check into a dedicated program. The information is then verified through an algorithm.

    *Provision of Program or SDK

Principle of Invisible Watermark

    Step 01. Create

    We encode the data into a unique code (58 bits: approximately 28 quintillion) and create an image.* The inserted data can be customized according to the policy

  • 샘플이미지

    Step 02. Create

    The encoded image is layered or composited into the content.

Applying Invisible Watermark

It can be applied to various materials such as film, paper, plastic, fabric, etc.

It can be used in various printing methods, from offset printing to digital printing.
