Abstract: A method of creating and applying a self-authenticating digital identity for a user having an identity is described.

Abstract: A computer-implemented method for providing a secured updated kernel module of an electronic device, wherein the method comprises the following steps: inserting by a computer a chameleon hash of a kernel module, a kernel module private key of the kernel module and an updated kernel module of the kernel module in a chameleon hash collision function thereby obtaining a collision data, combining by the computer, the updated kernel module with the collision data obtaining thereby a secured updated kernel module. Additionally, it is further described a computer-implemented method for secure updating at least one kernel module of an electronic device, a system comprising a server and an electronic device, computer programs and a computer-readable medium.

Abstract: The present invention is related to a computer implemented method for validating a voucher in an electronic voucher system, the electronic voucher system comprising a voucher holder application, an attestation application, a voucher issuer application an issuer server application, a voucher collector application, a smart contract system or SCS. An electronic voucher system, a computer program product and a computer-readable storage medium for carrying out the steps of the method is also described.

Abstract: An exemplary system includes a blockchain system that includes a blockchain, a smart contract template, and a smart contract generated based on the smart contract template, the smart contract executable to facilitate, by way of the blockchain, exchanges between parties to the smart contract. The system further includes an interface system communicatively coupled to the blockchain system and configured to perform a set of operations to provide an interface to the blockchain system, the set of operations including receiving a user input from an application executed on a user computing device, translating the user input to a call to the blockchain system, and issuing the call to the blockchain system. The blockchain system is configured to perform, based on the call and the smart contract, an action on the blockchain that represents an exchange between the parties to the smart contract.

Abstract: A computer-implemented method for escrowing secret data in a server of a client-server network, the client-server network comprising: a first client having at least one public and private client key pairs, at least one trusted client having at least one public and private trusted client key pairs, a server having a public and private server key pairs, a blockchain system comprising a plurality of nodes which are configured to store the public keys of the elements of the client-server network. It is also described a computer-implemented method for obtaining secret data of a server wherein the secret data is escrowed with the above computer-implemented method for escrowing secret data in a server. System, computer-readable mediums and computer programs, which are configured to implement or perform said computer-implemented methods, are also described.

Abstract: An exemplary method includes maintaining encrypted identity data associated with a user, the encrypted identity data representative of a digital identity of the user, receiving an access request from a service provider system for the service provider system to have access to the digital identity of the user when the user attempts to access a service provided by the service provider system, transmitting, in response to the access request, an authorization request to a computing device associated with the user, the authorization request prompting the user to authorize sharing of the digital identity with the service provider system, receiving, from the computing device, authorization data indicating that the user authorizes sharing of the digital identity with the service provider system, and providing, in response to receiving the authorization data from the computing device, the service provider system with access to the digital identity.

Abstract: A system and method for a self-authenticating identity. A self-authenticating identity is a digital identity created in an embodiment by aggregating a user's verified identity information and its public key, both of which are digitally signed by the user and an identity provider. This cryptographic binding allows the user to prove it is in fact the true party that the identity was issued to, without the need for a third party to be directly involved. The identity may also contain information that conveys how the identity was verified.

Abstract: The present invention relates to a method for generating a code and a method comprising the authorization of an operation carried out by a client on a first server. A second server generating an authorization code according to an encoding method is involved in the authorization. The operations can be transactions, access to a web page, user-to-user payments, user-to-business payments, online user-to-business payments, cash withdrawal in automated teller machines, etc.
