Definitions
- Blockchains are secured by a cryptographic system, and are accessed by users through private keys which, for security reasons, are generally known only to them.
- this cryptographic system is based on a pair of keys linked together by mathematical functions, including a private key, that the user must keep secret, and a public key, which represents the user's cryptographic address.
- rights and assets are materialized in digital form and associated with public keys, and only users holding the corresponding private keys can manage said rights and assets.
- a portable computer medium such as for example a cell phone or a USB key (for English "Universal Serial Bus"), or in a third-party server.
- the invention aims to improve the prior art by proposing in particular a method for allowing a user to easily manage his rights and assets on a blockchain, in particular by allowing him to retain access to them even in the event of loss and / or theft.
- User 2 can be a natural person, in particular an individual holding rights and assets for personal use on the blockchain, or a legal person, for example a representative of a company holding rights and assets on said blockchain. .
- the method provides for the creation of a digital safe 3 linked to the user 2, in particular by an administrator of the digital safe service.
- the platform 4 comprises means for allowing an administrator to create a safe 3 for the user 2, for example by means of a suitable programming interface (API, for English "Application Programming Interface ").
- API Application Programming Interface
- the user 2 can include several pairs of keys 1 a, 1 b for access to the same block chain and / or to several different block chains, the platform 4 being able to record all the rights and assets of said user linked to said keys in his safe 3.
- the method provides for the collection of the public key 1b created on the terminal 6 of said user.
- the terminal 6 sends to the central platform 7 a message 8 containing in particular the public key 1b, said platform being arranged to receive said message and extract said public key therefrom by means of suitable collection means.
- the method then provides for the association with user 2 of the collected public key 1b, the central platform 7 comprising suitable means for carrying out such an association.
- the method provides for the identification of user 2 with a third-party identification platform 9, said identification being performed in parallel with the collection of the public key 1b to associate said public key with said user.
- the method provides for the provision by the user 2 to the third-party identification platform 9 of a digital identity allowing said user to access a third-party service 10 linked to said platform, the identification of the user 2 being carried out at by means of said digital identity.
- a user 2 can access sensitive online services 10, for example a tax payment (impots.gouv.fr), social security (ameli.fr), or management service. secure titles (ants.gouv.fr), by limiting connection sessions, which reduces the risk of theft of its digital identities.
- sensitive online services 10 for example a tax payment (impots.gouv.fr), social security (ameli.fr), or management service.
- secure titles ants.gouv.fr
- such a platform 9 does not keep in memory the digital identity used by the user 2 to connect, which further limits the risks of the usurpation of said digital identity.
- the means of association of the central platform 7 are arranged to send to the third-party identification platform 9 a request 11 to ask the user 2 to provide a digital identity allowing him to access the network.
- one of the third-party services 10 linked to said platform in order to identify said user by means of said digital identity.
- the platform 9 can display on the terminal 6 a field that the user 2 must fill in with the corresponding digital identity, as well as a confirmation button that the user 2 activates once said field. filled in to send to said platform a message 14 containing said digital identity.
- the method provides for associating the public key 1b communicated by the terminal 6 with the digital identity provided by said user.
- the third-party identification platform 9 after receiving the message 14, the third-party identification platform 9 sends the central platform 7 a notification 15 comprising the digital identity of the user 2, the association means of said central platform being arranged to associate said digital identity with the public key 1b.
- the method then provides for the registration and association of the public key 1b with the safe 3 of the user 2, in order to allow the said user to authenticate himself subsequently with the digital safe 3 by means of said key. public, and thus access its rights and assets on the blockchain.
- the central platform 7 comprises means for interacting with the platform 4 for providing a digital safe service, in order to register the public key 1b therein by associating it with the safe 3 of the. user 2.
- the method can provide, during the creation of the safe 3, to link said safe to the user 2 by associating the digital identity mentioned above with the digital address 5 of said safe, so as to use said digital identity to store the public key 1b in said safe.
- the registration means of the central platform 7 can be arranged to use the digital identity communicated by the third-party platform 9 to obtain the digital address 5 of the safe 3 of the user 2, and thus register there. the public key 1 b.
- the method provides for the sending on the terminal 6 of the user 2 of an access link to his digital safe 3, in particular the public address 5 of the smart contract implementing said safe.
- the central platform 7 comprises means for sending the terminal 6 a message 17 including such a link 5 to allow the user to access his rights and assets stored in the safe 3.
- the link can be arranged to allow, when the user 2 activates it, the display on his terminal 6 of a user interface allowing him to send the public key 1 b from his terminal 6 to the platform 4 , in particular by means of a message 18, in order to authenticate himself to the safe 3 by means of said public key, and thus to access his rights and assets on the blockchain.
- the user 2 can associate several terminals 6 with his digital safe 3, in particular by repeating the process described above to register the public keys 1 b, 1 c, 1d of each of said terminals.
- user 2 can access his rights and assets by means of several terminals 6, which allows him in particular to retain access to his rights and assets even in the event of loss and / or theft of one of said terminals.
- the method can allow user 2 to registering a new terminal 6 in place of the old one, in order to not only allow it to access its rights and assets again, but also to prevent a third party from accessing them by means of the old terminal.
- the method may provide for recording the public key 1b instead of a possible old public key 1c, 1d linked to an old terminal of user 2 and previously associated with the safe 3 of said user, and the central platform 7 may include means for performing such recording.
- the user 2 can easily and without danger destroy a public key 1b, 1c, 1d of a terminal 6 which he no longer uses.
