[0014] - outputting a visual aid for accessing the device using the security information.
[0015] The device to be protected is designed in particular as a device of an industrial automation system, in particular as a device in a production environment, in particular as a device, in particular as a control device. The lock in particular protects access to a local device interface of the device. Releasing the lock enables access to the local device interface of the device. The local device interface is in particular designed as a local user interface, so that no remote access via a data communication connection is involved.
[0016] Alternatively or additionally, the device is designed as an electronic lock of a control cabinet or a door to an equipment room. The lock is especially designed as an electronic lock. In this embodiment, the access protection is especially designed as access protection.
[0017] In summary, the access protection is designed in particular to:
[0018] - electronic locks for control cabinets; and / or
[0019] - an electronic lock on the door to the equipment room where the equipment is located; and / or
[0020] - management functions of the device, in particular the protection level of the device, and / or the configuration menu of the device; and / or.
[0021] The security information enables access to the device. Access to the device is thus protected, in particular blocked, by access protection, in particular access protection. The security information enables access protection, in particular access protection, to be released and thereby access to the device, in particular to a local device interface of the device, to be enabled.
[0022] The recording of the device identification of the device is in particular designed as a visual recording. The recording is carried out in particular by means of a camera. The user is in a position in which the device and in particular the device identification are in the field of view of the user's camera.

[0024] The device identification is recorded, in particular, by a camera.
[0025] The security information is received by the receiving unit and sent by a password repository (password storage), which can also be referred to as a password storage unit or security code database. The security information is thus retrieved from the password repository. The security codes stored in the security code database are stored in particular in an encrypted manner.
[0026] In one embodiment, pure safety information is received and a display of safety information is created therefrom by the AR device (AR-enabled device). In an alternative embodiment, a display of safety information has been received and thus the safety information has been received in a processed form by the display.
[0027] A visual display is output, wherein the visual display includes at least a portion of an image of the device and a display of the security information. The image of the device particularly includes a real-time video playback of a field of view of the device. In addition to a portion of the image of the device or an image of the device as a whole, the security information is also output using the visual display.

[0028] The method according to the present invention provides the following advantages in particular: users who are unable to remember the corresponding security information, in particular service technicians and / or augmented reality (AR) users, do not need to manually carry the corresponding security information, in particular the security code, on a piece of paper, or ask other service technicians for the corresponding security information, for example by telephone.
[0029] This not only increases the security level, but also reduces the time required to unlock the necessary locks and access protection. The accesses made can also be recorded and thus traceable.
[0030] The invention exploits the possibilities, in particular those created in a production environment by means of industrial 5G system augmented reality, to simplify the entry of conventional security information, in particular device codes and / or PINs.
[0031] In this case, in particular, the visual aid is output in addition to the security information. The visual aid is therefore different from the security information itself. The visual aid being "suitable for using the security information" also includes that the visual aid makes it easier for the AR user to use the security information to unlock the lock, i.e., assists the AR user in this. Therefore, in particular, the visual aid is output additionally for unlocking the lock using the security information.
[0032] The output of the visual aid is therefore performed in addition to the output of the visual display, which includes a portion of the image of the device to be protected and the display of the security information.
[0033] The visual aid assists the user in correctly inputting the security information. Thus, the visual aid assists the user in unlocking the lock by correctly using the security information.

[0034] In one embodiment of the present invention, the security information is designed as follows:
[0035] - Facility code; and / or
[0036] - PIN code; and / or
[0037] - an unlock code; and / or
[0038] - password; and / or
[0039] - a numerical code; and / or
[0040] - Alphanumeric code.
[0041] As mentioned above, the security information enables access to the device by removing the access protection. The security information is especially designed as a series of characters that the user queries.
[0042] In a further development of the invention, the visual display is designed as an augmented reality display. According to the invention, the visual display comprises at least a part of an image of the device to be protected and a display of the security information.
[0043] As mentioned above, the image of the device includes in particular a real-time video playback of the field of view of the device. In addition to the image of a portion of the device or the image of the device as a whole, the security information is also output using a visual display. Thus, the security information is faded into the user's field of view in relation to the image of the device, in particular next to the device and superimposed with the device.
[0044] For the technical implementation of the output of the visual display, in particular, known augmented reality methods are used. The AR system fades the security information, in particular the corresponding code, into the field of vision of the AR user.
[0045] In another embodiment of the invention, the visual aid is designed as follows:
[0046] - enhancing the area of the operating panel used to enter the security information; and / or
[0047] - enhancing the keys of the numeric keypad used to enter the security information; and / or
[0048] -Warning display.
[0049] In the sense of the present invention, augmentation may also be referred to as visual highlighting, in particular by means of augmented reality techniques.
[0050] In this embodiment, the corresponding operating panel is also highlighted, in particular after it has been recognized by the AR system, in particular the corresponding key of the numeric keypad is highlighted.
[0051] In another embodiment of the invention, the method according to the invention has the following steps:
[0052] -Record user actions on or associated with the device.
[0053] In this way, user operations performed by a user, in particular the input of security information, can be detected, in particular by detecting a key press by image evaluation.
[0054] It is also possible to monitor whether the AR user has actually made the correct input on the operation panel.
[0055] In a further embodiment of the invention, the visual aid is output in response to an evaluation of the user operation.
[0056] According to this embodiment, in particular, in response to the evaluation of a previously performed user input, a character is output as a visual aid. The output is performed in particular via a display and / or an AR system, via which the visual display is also output according to the invention. The character is in particular designed as an asterisk "*", which represents a previously performed user input.
[0057] The corresponding next character to be input or the next number to be input may also be highlighted by the visual aid in the form of a visually faded-in character string or number sequence, or only the next character or number to be input may be displayed.
[0058] In addition, if the AR user is monitored to see whether he has actually made a correct input on the operation panel, the visual aid can be used to indicate to the user that an incorrect input has occurred in the event of an incorrect input. This is particularly done through a warning display, in which the incorrect input is particularly presented in a red marking.
[0059] In another embodiment of the invention, the method according to the invention has the following steps:
[0060] - Before receiving the security message, send a verification message.
[0061] In particular, the verification information is sent after visually recording the device identification information.
[0062] The verification information confirms that the sender of the device identification information has the right to receive the security information. The sender of the security information checks the verification information before sending the security information.
[0063] In another embodiment of the present invention, the verification information is designed as follows:
[0064] -Device authentication information; and / or
[0065] - location information; and / or
[0066] - User authentication information; and / or

In particular, the device assigned to the device authentication information or the assigned input field is identified. This is especially done by object recognition or based on a barcode attached to the device, especially a two-dimensional barcode (2D-Barcode) or a QR code. Thus, it can be checked whether the AR user is actually located right in front of the corresponding device, and whether the input field is currently available, especially whether it is not blocked by a shield, or whether the device is currently waiting for the input of a security code corresponding to the device display.
[0069] The position information makes it possible to detect whether a user or an AR pair of glasses or an AR device used by the user is located in the vicinity of the device or input field. This can also be done by image evaluation. In addition, however, the position information can also be collected and checked by a positioning system, in particular RFID, NFC, WLAN, UWB, 5G mobile communication.
[0070] The wearer of the AR glasses (an embodiment of the AR device) can be identified and / or authenticated by means of the user authentication information. This is done in particular by biometric authentication, in particular by means of a camera, which for AR glasses recognizes iris patterns and / or fundus, or by means of an acoustic fingerprint (ultrasound) of the wearer or the head, whereby an acoustic fingerprint of the skull is captured and checked.
[0071] Information about applications, especially correct or incorrect applications of user devices, is provided through application information of user devices. User devices, which may also be referred to as User-Device, are especially mobile devices, especially smart devices or tablet computers with AR applications, or AR glasses. Through the application information, it is possible to check whether the AR glasses are worn correctly. To this end, the orientation of the AR glasses can be detected in particular by an orientation sensor or a touch sensor, in particular on the bridge of the nose and / or temples of the AR glasses. It can also be checked whether the eyes are actually at the expected distance or expected position relative to the AR glasses.
[0072] The security information stored in the security code database is stored in an encrypted manner. In a variant, the cryptographic key for decrypting the encrypted security information can be activated only when the authentication information has been checked and in particular the AR user is currently allowed to use the security information.
