摘要: A system and method for establishing licensor changeable limits on shared software usage without the having access to which is running. An encrypted numerical limit value embedded in licensed (program); when program executed ("accessed"), as a first step, decrypts (204) compares it number of users currently accessing (210). If less than limit, then allowed (214). equal (or greater than) denied (212).
