Abstract:
The invention relates to a motor vehicle display apparatus having an electronic device containing: - a first memory area (117) for storing data (109), - a second memory area (119) for storing at least one first certificate (178), - a first interface (103) for receiving the data, a signature for the data and the at least first certificate from a transmitter (107), - means (123) for checking the validity of the signature for the data with the aid of the first certificate, wherein the data are stored in the first memory area only when the signature is valid, - means (127) for driving a display apparatus (136) for reproducing the data stored in the first memory area, and having the display apparatus (136), wherein the display apparatus and the electronic device form a structural unit.
Abstract:
The invention relates to a document with an integrated display (104), having an interface (102) for receiving authorization data (118) and a signature (120) of the authorization data, having means (110) for verification of the signature, having means (108, 114) for activating the display for outputting at least a part of the authorization data, wherein said output only occurs if said signature is valid, and wherein said interface is implemented for transmitting said authorization data and said signature.
Abstract:
The invention relates to a document with integrated display device, containing a number of controllable display elements of similar construction, said number having a first and a second part number of display elements, each display element of the first part number having a first intensity on a given instruction and each display element of the second part number having a second intensity on the same instruction, wherein the second intensity is less than the first intensity and by means of the arrangement of the display elements of the first and second part numbers information can be encoded.
Abstract:
The invention relates to a document, in particular a valuable or security document, comprising a display device (100), wherein the display device has first drivable display elements (102; 146), which require no power supply for the reproduction of data, and second drivable display elements (104; 148), which require a power supply for the reproduction of the data, and comprising control means (106) for driving the first and second display elements (102, 146, 104, 148) for the reproduction of the same data.
Abstract:
The invention relates to a document having a display apparatus (102) for image reproduction in a visually perceptible spectral range, where the display apparatus is in the form of an optical transmitter (102) for outputting at least one machine-readable optical signal in a visually imperceptible spectral range.
Abstract:
Die Erfindung betrifft ein Verfahren zum Ausstellen eines digitalen Credentials (110) für eine Entität durch ein Ausstellercomputersystem (100). Das Verfahren umfasst ein Empfangen einer Ausstellanfrage (600) zum Ausstellen des digitalen Credentials (110) über ein Netzwerk (103) von einem anfragenden Computersystem (150). Dies Ausstellanfrage (600) umfasst eine der anfragenden Entität zugeordnete Domain (304), eine E-Mail-Adresse eines offiziellen Vertreters der Entität und einen Decentralized Identifier. Das Ausstellercomputersystem (100) stellt das digitale Credential (110) mit entitätsbezogenen Attributen unter Verwendung eines digitalen Registerauszugs aus und sendet es in Antwort auf die empfangen Ausstellanfrage (600) über das Netzwerk (103) an das anfragende Computersystem (150).
