Title (EN) TRANSACTION PRIVACY IN PUBLIC DISTRIBUTED LEDGER SYSTEMS
(FR) CONFIDENTIALITÉ DE TRANSACTIONS DANS DES SYSTÈMES À REGISTRE DISTRIBUÉ PUBLIC
Abstract:
(EN) Embodiments of the present invention provide methods of implementing a private but traceable primary transaction implementing a transfer of an asset from an originator to a recipient using a third party, using a distributed network of computers implementing a distributed ledger. The methods use a third party to accept a transaction request from an originator. The third party then separates the transaction into a plurality of secondary transactions, characterized by various steps to make reconstruction of the original transaction difficult. The secondary transactions are recorded on the distributed ledger, accomplishing the original transaction without having any single transaction on the publicly accessible distributed ledger that directly corresponds to the original transaction, ary transactions.
(FR) Des modes de réalisation de la présente invention concernent des procédés de mise en œuvre d'une transaction primaire privée mais traçable mettant en œuvre un transfert d'un actif depuis un émetteur vers un destinataire via une tierce partie, à l'aide d'un réseau distribué d'ordinateurs mettant en œuvre un registre distribué. Les procédés font appel à une tierce partie pour accepter une demande de transaction émanant d'un émetteur. La tierce partie sépare ensuite la transaction en une pluralité de transactions secondaires, cette opération étant caractérisée par diverses étapes pour compliquer une reconstruction de la transaction d'origine. Les transactions secondaires sont enregistrées sur le registre distribué, ce qui permet de réaliser la transaction d'origine sans avoir une quelconque transaction individuelle sur le registre distribué accessible au public qui correspond directement à la transaction d'origine.
