OriginalMy is a Brazilian-founded company that uses public blockchains to prove that digital content, documents, signatures and identities are authentic. Its services are aimed at companies, governments and professionals, such as lawyers and creators, who need evidence that a web page existed, that a file has not been changed or that a named person really signed a contract.
Each item OriginalMy certifies gets a fingerprint recorded on a public blockchain with a timestamp, so any later change can be detected by anyone who checks it.

What OriginalMy Does
Digital evidence is easy to dispute. A screenshot can be edited, a file can be altered after the fact and an electronic signature does not always show who actually signed. OriginalMy closes that gap with an immutable authenticity record for each item it certifies, anchored on a public blockchain rather than held in its own database. The same approach covers evidence capture, proof of authorship, signing and personal identity, and it helps companies that collect personal data show consent under Brazil’s LGPD data protection law.
Products
PACWeb
PACWeb is a Chrome plugin for anyone who needs to preserve online content as evidence, for example in a legal dispute. It captures a full copy of the page with a report proving the content existed, records metadata such as IP address, time zone, local time and approximate geolocation, and certifies the capture on blockchain with the exact date and time it was collected. The user receives a Certificate of Authenticity.
PACDigital
PACDigital protects the authorship of digital files such as music, e-books, source code and business documents. Only the file’s hash is certified, so the file itself never leaves the owner, and a record with a timestamp from a public blockchain is created in about 10 minutes. Organisations certifying files at volume can do the same through APIs.
OMySign
OMySign signs PDF contracts and documents online and is built to prove who signed. Signers are identified through OMyPass, several signers can sign the same document, and a fraud analysis runs before signing. The document hash is certified on blockchain, and signing is blocked if the document has been altered.
OMyPass
OMyPass gives people and companies a single digital identity. Businesses can use it in place of registration forms to cut KYC costs, and the same identity can open access at websites, gates and turnstiles. Both OMyPass and OMySign are being discontinued and run only up to Android 12 and iOS 18.
How It Works
Every service starts by generating a hash, a unique code that identifies a document or capture. That hash is certified on a public blockchain with a timestamp, and any change to the file produces a different value, which is how tampering shows up.
OriginalMy does not keep certified files or the contents of identity documents, only a digital signature of each one. OMyPass creates a blockchain identity whose private part stays on the user’s phone, and only public information is sent to OriginalMy’s servers for validation.
Customers use the services through a logged-in web area, the OriginalMy mobile app and the PACWeb plugin. Enterprise customers can connect through APIs.
