    • Method, system, and storage medium for reducing or minimizing access to sensitive information. A method includes identifying processes and data associated with a computer system and classifying each of the data as one of either sensitive information or non-sensitive information. The sensitive information includes at least one of: data that is personal to an individual, confidential data, and data that is legally subject to conditions of restricted use. For each of the processes the method includes selecting a process and a sensitive data item, modifying the sensitive data item, analyzing the behavior of at least the selected process, and preventing access of the sensitive data item by the selected process if, as a result of the analyzing, the sensitive data item is determined not to be needed by the selected process.
    • 用于减少或最小化敏感信息访问的方法,系统和存储介质。 一种方法包括识别与计算机系统相关联的过程和数据,并将每个数据分类为敏感信息或非敏感信息之一。 敏感信息包括以下至少一项:对个人个人的数据,机密数据和法律上受限于使用条件的数据。 对于每个过程,该方法包括选择过程和敏感数据项,修改敏感数据项,分析至少所选过程的行为,以及如果结果,则阻止敏感数据项的访问。 在分析的情况下,敏感数据项被确定为所选择的处理不需要。

    • Software licence management systems are provided in which a licence to use a software product is represented by a data token. The systems have a software controller for controlling use of the software product at a user device, and a licence management server for communicating with the software controller via a data communications network. The software controller allows use of the software product at the user device substantially only during a use period associated with a current data token supplied to the software controller by the licence management server. An exchange token can be supplied to another, similar software controller when necessary to transfer the licence, e.g. in the event of a breakdown. The software controller is adapted to supply either the current data token, or the exchange token, to the licence management server to be exchanged for a new data token.
    • 提供了软件许可证管理系统,其中使用软件产品的许可证由数据令牌表示。 该系统具有用于控制在用户设备处使用软件产品的软件控制器,以及用于经由数据通信网络与软件控制器进行通信的许可证管理服务器。 软件控制器允许基本上仅在与由许可证管理服务器提供给软件控制器的当前数据令牌相关联的使用期间内在用户设备处使用软件产品。 交换令牌可以在必要时提供给另一个类似的软件控制器来传送许可证,例如 发生故障时。 软件控制器适于将当前数据令牌或交换令牌提供给许可证管理服务器,以交换新的数据令牌。

    • Provides methods, apparatus and systems for determining an applicable policy for an incoming message having a service-level addressing element. A method includes the following steps: a) applying a potentially applicable policy (P1) on the incoming message to make the service-level addressing element of the incoming message visible, b) if the service-level addressing element of the incoming message gets visible and is the one to which the currently applied policy (P1) is associated, the currently applied policy (P1) is determined to be the applicable policy, and if not associated c) repeating steps a) and b) with a further potentially applicable policy (P2 . . . Pn).
    • 提供用于确定具有服务级别寻址元素的输入消息的适用策略的方法,装置和系统。 一种方法包括以下步骤:a)对传入消息应用可能适用的策略(P1),使得传入消息的服务级寻址元素可见,b)如果传入消息的服务级寻址元素可见 并且是当前应用策略(P1)所关联的策略(P1)的当前应用策略(P1)被确定为适用策略,如果不是相关联的c)重复步骤a)和b)具有进一步潜在适用的策略 (P2 ... Pn)。
