摘要： A document having a non-volatile memory area for storing a secret identifier that has a first n-digit character sequence from a predefined character set; a random generator for selecting at least one character from the predefined character set for replacement of at least one character of the first character sequence, such that a second n-digit character sequence is defined as a result of this replacement; a volatile memory area for storing the at least one selected character; a display device for displaying the at least one selected character; an interface for inputting a third character sequence; and a processor element for authenticating the user to the document, wherein the processor element is configured to access the non-volatile memory area and the volatile memory area in order to read the second character sequence and check for a match between the second and third character sequences in order to authenticate the user.
