Abstract
With confidential information being composed of authenticating signs which belong to a first series, a second series of signs or designating symbols is defined, the first and second series of signs are displayed in a relatively random position, and this placement in correspondence is used to enter the confidential information in such a way that a third party who observes the entry operations cannot determine the confidential information. The invention also relates to the terminal associated with this process.
