  • Patent number: 7676668
    Abstract: The subject application is directed to a method and system for notifying an administrator when a user of a document processing device requests a change in the configuration of the device. A user accesses the device via a user interface, requesting alteration of the device configuration. The user then provides identification information and an authentication server determines whether the identified user is authorized to make the configuration change. Access is denied to unverified or unauthorized users attempting to change the configuration of the device. When the user is verified, but not authorized to make the requested change, the authentication server rejects the request and notifies the administrator of the attempt. When the user is both verified and authorized to make a change, the device configuration is altered, conforming to the requested configuration, and a notice is transmitted to the administrator containing information about the change in configuration.

  • Publication number: 20090288147
    Abstract: The subject application is directed to a system and method for modifying at least one security function of an associated document processing device. Data representing security functions of the document processing device is stored in associated memory. Login data is then received from an administrator via an associated user interface. Selection data is received corresponding to a security function on the document processing device to be enabled. The selected security function is then selectively enabled via the document processing device. Enhanced mode selection data is then received from the administrator corresponding to an enhanced security mode of operation. Each security function associated with the enhanced mode is simultaneously enabled. Operations of the document processing device are thereafter controlled in accordance with each selectively enabled security function.

  • Publication number: 20090217372
    Abstract: A preset security level system and a method for utilizing the preset security level system. The system includes a plurality of security levels, each of which enables a different level of security. Each of the security levels has associated therewith security features, such that low security level features are associated with a low security level, etc. The system and method enable a system administrator to select a desired security level, which selection automatically results in the activation of the associated security features, rather than manually activate each desired security feature.

  • Publication number: 20090119755
    Abstract: The subject application is directed to a system and method for controlling access to a document processing device based on roles assigned to user groups. Each group of users has certain functions for which they are authorized to use a document processing device. The device determines the group to which the user belongs, and then determines those functions of the device for which the group is authorized. The device then compares the requested function with the authorized functions to determine if the group to which the user belongs is allowed to use the document processing device for the requested function. The document processing device then performs the authorized requested function or denies use of the device for an unauthorized function.

  • Patent number: 7506160
    Abstract: The present invention is directed to a system and method for adding data encryption services to a document processing device. Encryption enablement software, which includes two alternate encryption mechanisms, is received by an associated document processing device. The device then awaits an associated user's selection of an electronic document file to be encrypted and subsequently encrypts the file using one of the available encryption mechanisms. The electronic document file is divided into blocks having a preselected length. An encryption key block containing first and second key portions, is then generated. The electronic data file is then encrypted using the first encryption key portion to form first level encryption data. The first level encryption data is then decrypted using the second encryption key portion to form second level encryption data. The second level encryption data is then encrypted using the first key portion to form a final encrypted electronic document file.

  • Patent number: 7478421
    Abstract: A system and method for controlling access to a document processing device based on roles assigned to user groups. Each group of users has certain functions for which they are authorized to use the document processing device. The device compares a username and password with correlating information stored in an authentication server. The server transmits a list of functions for which the user is authorized to employ the device. The device then compares the requested function with the authorized functions to determine if the user is allowed to utilize the document processing device for the requested function. The document processing device then performs the authorized requested function.

  • Patent number: 7246223
    Abstract: A method and system for notifying an administrator when a user of a document processing device, such as a multifunction peripheral device, requests a change in the configuration of the document processing device. A user accesses the document processing device via a user interface, requesting that the configuration of the device be altered. The user then provides identification information verifying the identity of the user. An authentication server then determines whether or not the identified user is authorized to make the change in the device configuration. Access is denied to unverified or unauthorized users attempting to change the configuration of the document processing device. In the event that the user is verified, but not authorized to make the requested change, the authentication server rejects the requested change and notifies the administrator of the attempt to change the configuration.
