  • Patent number: 8468579
    Abstract: The subject disclosure pertains to systems and methods that facilitate managing access control utilizing certificates. The systems and methods described herein are directed to mapping an access policy as expressed in an access control list to a set of certificates. The set of certificates can be used to grant access to resources in the manner described by the ACL. The certificates can be distributed to entities for use in obtaining access to resources. Entities can present certificates to resources as evidence of their right to access the resources. The access logic of the sequential ACL can be transformed or mapped to a set of order independent certificates. In particular, each entry, position of the entry in the list and any preceding entries can be analyzed. The analysis can be used to generate order independent certificates that provide access in accordance with the access policy communicated in the ACL.

  • Patent number: 7900248
    Abstract: The subject disclosure pertains to systems and methods that facilitate managing groups entities for access control. A negative group is defined using a base group, where the negative group associated with a base group includes any entities not included in the base group. Negative groups can be implemented using certificates rather than explicit lists of negative group members. A certificate can provide evidence of membership in the negative group and can be presented for evaluation to obtain access to resources. Subtraction groups can also be used to manage access to resources. A subtraction group can be defined as the members of a first group, excluding any members of a second group.

  • Publication number: 20080307486
    Abstract: The subject disclosure pertains to systems and methods that facilitate entity-based for access management. Typically, access to one or more resources is managed based upon identifiers assigned to entities. Groups of identifiers can be assigned to access rights. An authority component can manage an exclusion group that excludes an entity, regardless of the identifier utilized by the entity. Access control components can utilize exclusion groups in access policies to define access rights to a resource.

  • Patent number: 7319454
    Abstract: A system and method for emulating the functional behavior of a two-button mouse-type computer input device is described. A predetermined input generated by digitizing pen and a digitizing writing surface is received, and a user interface having a plurality of soft buttons is displayed. The plurality of soft buttons provides selectable functionality of a two-button mouse-type computer input device. Preferably, the plurality of soft buttons includes a right-button function, a shift function, a control function, an alternate function and a bull's-eye function.
