摘要： A computer-implemented method includes identifying a plurality of protected pieces from a conversation. The computer-implemented method further includes generating one or more confidence scores for each protected piece, wherein a confidence score is a degree of associativity between a protected piece and a type of sensitive information. The computer-implemented method further includes determining that the protected piece is associated with the type of sensitive information. The computer-implemented method further includes determining a type of protection action for each protected piece in the plurality of protected pieces. The computer-implemented method further includes performing the type of protection action for each protected piece in the plurality of protected pieces to form a modified conversation that is devoid of the sensitive information. A corresponding computer system and computer program product are also disclosed.

摘要： A system, apparatus and method for transparently authenticating continuous data streams. A continuous data stream is divided into data blocks. Block authentication code(s) are determined using the data in the data blocks, a hash function and a key. The block authentication code(s) are embedded into the data block(s) by adjusting the timing between the packets in the data block(s). Timing delays may be used to separate the blocks. The continuous data stream may be received and authenticated by comparing an extracted block authentication code with a new calculated content-based block authentication code.

摘要： An arrangement for the cipher controlled exploitation of data resources (e.g., securely storing and retrieving sensitive data or securely registering and logging on a computer system) includes the steps of providing a subscriber identity module carrying a security algorithm; generating at least one, e.g., two, random values; subjecting the random value to the at least one security algorithm to generate at least one, e.g., two, session keys; processing the session keys via a mixer function such as a hash function to produce a cipher key; and using the cipher key thus produced for exploiting the data resources.

摘要： A global key control mechanism provides a single point of overall control for key generation, but portions of the key generation and/or allocation tasks may be delegated to client computer systems, thereby reducing network traffic. The global key control mechanism may download a client key generation mechanism on one or more client computer systems, and may allocate a block of keys to the client key generation mechanism. Requests for keys may then be routed to the client key generation mechanism, which can generate and/or allocate keys within the block of keys that the global key control mechanism allocated to it. When the block of keys is used up, the client key generation mechanism may request another block from the global key control mechanism. The preferred embodiments also include the capability of downloading a client key generation mechanism with an associated block of keys once the requests from one or more client applications exceed a predetermined threshold. In addition, the preferred embodiments include a hierarchy of key control mechanisms, with a single global key control mechanism that maintains control over one or more client key control mechanisms that may, in turn, control other client key control mechanism(s) or which may generate and/or allocate keys directly to requesting applications.
摘要翻译：全局密钥控制机制为密钥生成提供单一的总体控制点，但是可以将密钥生成和/或分配任务的一部分委托给客户端计算机系统，从而减少网络流量。全局密钥控制机制可以在一个或多个客户端计算机系统上下载客户端密钥生成机制，并且可以向客户端密钥生成机制分配密钥块。然后可以将密钥的请求路由到客户端密钥生成机制，其可以生成和/或分配密钥块内的密钥，全局密钥控制机制分配给密钥。当密钥块用尽时，客户端密钥生成机制可以从全局密钥控制机制请求另一个块。一旦来自一个或多个客户端应用的请求超过预定阈值，优选实施例还包括下载具有关联密钥块的客户机密钥生成机制的能力。此外，优选实施例包括密钥控制机制的层次结构，具有单个全局密钥控制机制，其维持对一个或多个客户端密钥控制机制的控制，所述客户端密钥控制机制又可以控制其他客户端密钥控制机制，或者可以直接向请求的应用程序生成和/或分配密钥。
