Identify the item itself — no tag required.

We develop AI image recognition software for manufacturing, starting with our proprietary image recognition product GAZIRU.z (Individual Identification), which reads the fine surface patterns already present on parts and products and identifies a single individual item from an image alone — no tags, labels, or engraving.

Why individual identification? Why tagless?

Why individual identification matters

With lot-based management, both the cause of a defect and the scope of a recall can only be narrowed down to "the whole lot." When you can distinguish each item individually, you can link history, inspection results, and shipping destinations to that item — so recalls target only the units that need it, and improvement efforts target only the process at fault.

What tagless identification gives you

Tags have three weaknesses: they can't always be attached, they can come off, and they can be swapped. GAZIRU uses the fine surface patterns already present on the product as its ID, so it works even on small parts and special materials, can't come off, and can't be swapped. The steps of attaching, removing, and engraving all disappear.

Identifying Individuals by Unique Surface Patterns

GAZIRU's individual identification technology captures microscopic patterns and textures that exist naturally on product surfaces at the micrometer (μm) level, or unique patterns that occur incidentally during the manufacturing process. Simply by taking a photograph of the surface, AI extracts features from the captured content and matches them against a database to identify individual objects with extremely high precision.

Unique Technology

Our proprietary image processing technology enables tag-free, fast and accurate individual identification across a wide range of targets simply by taking photographs

✓

Non-invasive & Tag-free

No processing or tagging of products required. Preserves aesthetics and enables individual management even for ultra-small parts that were previously difficult to manage

✓

High Precision & Reliability

Recognizes minute differences and keeps misidentification low

✓

High-speed Processing

Even on general-purpose servers, matches against a pool of one million items in around a second.※1

✓

Versatility

Works with any target without requiring object-specific learning or tuning. Supports diverse materials including metal, plastic, paper, fabric, from flat to three-dimensional objects

✓

API Integration

Easy integration with customer systems through engine interfaces (RESTful WebAPI) provided by cloud services or on-premise products installed on servers

Notes

※1 Time to find one individual among 1,000,000 registered items: about 1.5 seconds with 3-way parallelism (without alignment; three machines with 8 physical cores / 64GB each within a public cloud platform; measured in-house in July 2026 on a GAZIRU.z V5.0.0 development build). Results for 4-way parallelism and above, or more than 1,000,000 items, are estimates based on the scaling trend confirmed by measurement. Actual response time varies with the equipment, network configuration and other conditions. With alignment enabled, response time also depends on the image content. A GPU option is available to speed up matching when alignment is enabled.

※2 The alignment feature automatically corrects, where possible, differences in shooting position and orientation at match time, and assists identification accuracy by raising the score only for the same (correct) individual.
