The Social Challenge We Solve

⚠️ When "It's Real" Is No Longer Enough

Generative AI enables anyone to create realistic videos, audio, and images
In court, "That could be AI-generated, right?" leaves you defenseless
The trustworthiness of digital evidence is fundamentally collapsing

✅ PIJ's Answer: Provable Trust

Tamper detection through cryptographic hash chains
Mathematical proof of registration time and edit history
Independent verification by third parties

Vision

From "Seeing is Believing" to "Proving is Believing".

We envision a society where anyone can verify the authenticity of digital content. A world where "being genuine" can be mathematically proven—in journalism, law, and corporate compliance. This is the future PIJ is building.

Message from the CEO

"Is that video real?"—With the advent of generative AI, this question has become extremely difficult to answer. Video generation AI like Sora, voice synthesis like ElevenLabs. While technological progress is remarkable, it has fundamentally overturned the assumption that "seeing is believing."

In three years, when asked in court "This video could be AI-generated, right?"—will you be able to respond? We want to create a world where you can answer "Yes, I can prove it." AI-VideoAuth is the first step toward that goal.

Since founding in 2005, PIJ Inc. has always faced "real-world challenges." Today, the greatest challenge we must address is the "collapse of digital evidence trust." We are a small company, but we are seriously committed to solving this social issue through the power of technology.

— Hiroshi Nakagawa, CEO, PIJ Inc.
