Serelay Idem

Take photos and videos from your mobile phone and be secure in the knowledge that if anyone anywhere on any platform manipulates or changes them in any way, their version will be known to be fake, and yours known to be true.

Serelay Idem lets you take photos and videos with an extra layer of proof that what you capture is authentic.

There's no sign up, and we don't take your personal details. We only take the information that we need — things like location and nearby Wi-Fi signals — to verify your photos and videos, and mark them authenticated, so if they pop up in a different context, everyone will know.

Your original photos and videos stay in your control, and you're free to share and distribute as you wish with full confidence.

Sharing Serelay trusted media captures lets you pick how much information you're sharing with your photo or video along with our proof of verification. This means you don't have to give away the precise location or time the picture or video was taken — we give you this all as a link for easier sharing.

Idem now supports the embedding of CAI (Content Authenticity Initiative) metadata. This means that instead of embedding a visual verification link in a photo, you can opt to embed origin metadata in the file itself. This metadata is digitally signed and will be readable by a growing number of applications including Adobe Photoshop and Behance. You can upload and check your CAI-compliant photos here: verify.contentauthenticity.org
