Claim 7

In a distributed system, a method for defining the access of a group's members on a specified workstation to a system resource, the method comprising the steps of: (a) generating an access code representing the group on the specific workstation; and (b) allowing the specific workstation access to the system resource whenever the access code indicates that a member of the group has delegated its access privileges to the specific workstation.

Claim 8

In a distributed system, a method for defining the access of a group's members on a specified workstation to a system resource, the method comprising the steps of: (a) generating an access code representing the group on the specific workstation; and (b) allowing the specific workstation access to the system resource whenever the access code indicates that a member of the group has delegated its access privileges to the specific workstation.

Claim 9

In a distributed system, a method for defining the access rights of a workstation to a system resource given the identity of a particular group having certain access privileges, the method comprising the steps of: (a) generating a role code indicating a subset of the group's access privileges to be delegated to the workstation; (b) generating an access code representing the group acting in the role represented by the role code; (c) delegating access privileges to the workstation on the basis of the generated access code; (d) generating a second access code representing the workstation acting with the access privileges delegated in step (c); and (e) allowing the workstation access to the system resource whenever the second access code indicates that a member of the group, acting in the role assigned in step (a) has delegated its access privileges to the workstation.

Claim 10

In a distributed system, a method for defining the access rights of a workstation to a system resource given the identity of a particular group having certain access privileges, the method comprising the steps of: (a) generating a role code indicating a subset of the group's access privileges to be delegated to the workstation; (b) generating an access code representing the group acting in the role represented by the role code; (c) delegating access privileges to the workstation on the basis of the generated access code; (d) generating a second access code representing the workstation acting with the access privileges delegated in step (c); and (e) allowing the workstation access to the system resource whenever the second access code indicates that a member of the group, acting in the role assigned in step (a) has delegated its access privileges to the workstation.

Claim 11

In a distributed system, a method for defining access for a group member to a system resource, the group member having certain access privileges and running a specified computer program on a specified workstation, the workstation having certain access privileges, the method comprising the steps of: (a) generating a role code representing the execution of the specific piece of software on that workstation; (b) generating an access code representing the group acting in conjunction with the assigned role represented by the role code; and (c) allowing the workstation access to the system resource when the access code indicates that it is executing the specified computer program and a member of the group is acting in conjunction with the execution of the specified computer program.

Claim 12

In a distributed system, a method for defining access for a group member to a system resource, the group member having certain access privileges and running a specified computer program on a specified workstation, the workstation having certain access privileges, the method comprising the steps of: (a) generating a role code representing the execution of the specific piece of software on that workstation; (b) generating an access code representing the group acting in conjunction with the assigned role represented by the role code; and (c) allowing the workstation access to the system resource when the access code indicates that it is executing the specified computer program and a member of the group is acting in conjunction with the execution of the specified computer program.

Claim 13
