METHOD AND DEVICE FOR CHECKING AND OBTAINING ACCESS RIGHTS

摘要

In order to check the access authorisation of a user of devices, a facility is sought for reliable checking which is independent of ancillary devices. A personal access code is generated by entering acoustic signals or other sound levels in parallel with randomly selected words or parts of words of an announcement text. A code generated in the same way during operation is compared and access is granted if correspondence is found. High security against unauthorised use is achieved at low cost since no ancillary devices are required. IMAGE
