Paving the way for a new notarial market, BELEM has developed an authentication tool that provides a simple, economical and safe way to record and protect personal or business data (industrial patent, certificates of birth/death, proof of residence and solvency, financial market data, diplomas, land and proof of ownership of physical items).
Blockchain enables to record a tamper-proof, irrefutable, and immutable proof of existence of data or documents. The time stamp of the latter via its digital signature serves as proof of its existence at a given date.
The content of the data being registered may be shared or remain confidential, but the footprint of the data can be audited by anyone. Security of the data is ensured. The inviolability of Blockchain counteracts the vulnerability of existing notarial processes.
