Abstract
An approach is provided for managing access rights of users to information spaces using signatures stored in a memory tag. A signature manager caused reading of a memory tag to initiate a request, from a device, for an initial access to an information space. The request includes an authorization signature associated with the device. The signature manager determines a level of access to the information space by comparing the authorization signature against a lattice of signature primitives associated with the information space. The signature manager then modifies the authorization signature based on the determination and stores the modified authorization signature for validation of subsequent access to the information space by the device.
