Abstract
Η εφεύρεση αναφέρεται σε ένα φορέα πληροφοριών για την τήρηση πληροφοριών χρήστη, όπου ο φορέας πληροφοριών περιλαμβάνει πληροφορίες πρόσβασης με τη μορφή δυαδικών ψηφίων πληροφοριών πρόσβασης για την πρόσβαση στις πληροφορίες χρήστη, όπου οι πληροφορίες πρόσβασης αποθηκεύονται στο φορέα πληροφοριών σε μία μεταβολή μίας παραμέτρου, η οποία μεταβολή είναι ανιχνεύσιμη μέσω ολοκληρωματικής ανίχνευσης. Τα δυαδικά ψηφία πληροφοριών πρόσβασης περιπλέκονται σύμφωνα με μία προκαθορισμένη μέθοδο περιπλοκής. Μέσω της περιπλοκής των δυαδικών ψηφίων πληροφοριών πρόσβασης σύμφωνα με μία προκαθορισμένη μέθοδο περιπλοκής, η ανίχνευση των πληροφοριών πρόσβασης δεν είναι δυνατή όσο δεν είναι γνωστή η μέθοδος περιπλοκής. Η χρήση της τεχνικής ολοκληρωματικής ανίχνευσης έχει σαν αποτέλεσμα οι πληροφορίες πρόσβασης να είναι γνωστές μόνο σε όποιον γνωρίζει πως πρέπει να γίνεται επεξεργασία του σήματος, το οποίο λαμβάνεται αφού αναγνώζεται η περιοχή, η οποία περιλαμβάνει τα δυαδικά ψηφία πληροφοριών πρόσβασης. Με αυτό τον τρόπο εμποδίζεται περαιτέρω η έκνομη ανάκτηση των πληροφοριών χρήστη.
