Computer-implemented method to provide secure interactions between users in a network

A computer-implemented method for securing an interaction between users of a computer network, the method comprising the following steps:

• creating a first digital identity for a first user of the users based on an input provided by the first user over a user interface of a first network node, the input provided by the first user including a first consent to create the first digital identity and a first secret content, the creating of the first digital identity including:
• merging the first consent and the first secret content to form a first root string, and
• creating the first digital identity dependent on the first root string;
• storing the first digital identity in the network in encrypted form;
• and
• interacting by the first user with other users in the network using the first digital identity;
• wherein:
• the first digital identity corresponding to the first user is stored in encrypted form in the identity management system,
• a second identity corresponding to a second user is created and stored in encrypted form in the identity management system,
• a first right to access first information or to access a first software function or to access a first product is assigned to the first digital identity, and
• the method further comprises:
• requesting by the second user an access to the first information or the first software function or the first product from the first user by sending a request to the identity management system,
• checking by the identity management system authentication of the second user based on the second identity,
• sending by the identity management system the request to the first user,
• denying or approving the request, by the first user, by responding to the identity management system,
• checking by the identity management system authentication of the first user based on the first digital identity,
• dependent on the check of the authentication of the first user, sharing secret access-rights information stored in encrypted form with the second user, the secret access-rights information allowing the second user to access the first information, the first software function or the first product,
• accessing by the second user the first information or the first software function or the first product.

A non-transitory computer-readable storage medium on which is stored a computer program for securing an interaction between users of a computer network, the computer program, when executed by a computer, causing the computer to perform the following steps:

• creating a first digital identity for a first user of the users based on an input provided by the first user over a user interface of a first network node, the input provided by the first user including a first consent to create the first digital identity and a first secret information, the first consent being a value of a digital binary parameter whose value is settable to only either of a first predefined value representing a positive indication and a second predefined value representing a negative indication, the creating of the first digital identity including:
• merging the first consent and the first secret information to form a first root string, and
• creating the first digital identity dependent on the first root string;
• storing the first digital identity in the network in encrypted form;
• and
• interacting by the first user with other users in the network using the first digital identity.
