Abstract: The invention is a method for securing a system including a plurality of entities and a repository storing usage patterns. The method comprises the following steps: for each of the entities involved in a transaction requested by a user, capturing a behavior data reflecting the dynamic behavior of said entity, generating a set of locality-sensitive-hashing hashes from each of said behavior data, computing a similarity score for each of the entities involved in the transaction, based on both said usage patterns and the set of generated locality-sensitive-hashing hashes, and based on a subset of the computed similarity scores, applying a preset security action to the transaction.

Abstract: A system configured to perform decision tasks carried out by a machine learning engine operates with a machine learning model, and includes a training component for improving the machine learning model, a device for carrying out decisions based on a set of input data, and an interaction interface for switching the machine learning model between training component and a device that includes a model attestation checker. The device performs acquiring input data, and ascertaining at least one machine learning model over the interaction interface. The model attestation checker performs checking if said machine learning model is trusted by a model attestation, and considering, for decision making, only those machine learning models that are trusted. The machine learning engine performs carrying out the decision task for input data by using a trusted machine learning model, and providing a result attestation for the decision output.

Abstract: The invention relates to an authentication method. The method comprises: collecting, based on a predetermined authentication policy, at least one context data element; constituting, based on the at least one collected context data element, a data packet; generating, by using a predetermined hash type algorithm and the data packet, as input to the predetermined hash type algorithm, a hash; sending the generated hash; generating, as a hash distance generation step, a hash distance between the generated hash and a predetermined reference hash; and authenticating successfully or not based on the generated hash distance, as an authentication step. The invention also relates to corresponding device and system.

Abstract: The present invention relates to a method for authentication of a user using a user equipment, comprising an authentication engine for authenticating at least one user, said authentication engine being configured to operate with a local authentication model, wherein the method comprises the step for the user equipment of enhancing its local authentication model by at least one authentication factor, wherein said at least one authentication factor is stored in the local authentication model with a validity indication, indicating the time the authentication factor is valid for taking into account by the authentication engine, and authenticating a user by means of a match of the local authentication model with a set of user behavior indications retrieved by the user equipment through the authentication engine.
