FIELD: physics, computer engineering.
SUBSTANCE: invention relates to protection of user information from unauthorised access using a pseudonym and can be used in electronic medical systems. The method and apparatus for generating and authenticating a pseudonym are intended for protecting user information from unauthorised access. The method comprises steps of: determining a set of public parameters and a set of private parameters; receiving a user identifier IDuser from a user device; generating a prime pseudonym based on the determined set of private parameters and the IDuser; and transmitting the prime pseudonym Pprime and the set of public parameters to the user device. A Personal Identity Manager (PIM) includes a unit for determining a set of public parameters and a set of private parameters, a unit for receiving a user identifier IDuser, a unit for generating a prime pseudonym and a unit for transmitting the prime pseudonym to the user device.
EFFECT: high information security of electronic systems.
