    摘要： A surveillance system connectable to a network, comprising a communication module and a management module; said system being configured to, during an initialization phase: a. intercept a first message being sent to a first device; b. intercept a second message said second message being a response from the first device to the first message; c. calculate a time interval between the interception of the first message and the second message; d. repeat the steps a. to c. to determine further time intervals; e. determine a distribution of said time intervals; f. store the distribution and during a surveillance phase, intercept a third message said message being sent to the first device; intercept a fourth message said fourth message being a response to the third message; calculate a new time interval between the interception of the third and fourth messages; and verify that the new time interval is within the distribution.

    摘要： A user's access to software applications installed on a device is limited by evaluating the context in which the user requests access to the application and determining, based on the context analysis, whether or not the user is to be given access to the application. When it is determined that the user requesting access is not a primary authorized user, the primary authorized user may be notified of the attempt to access the application.

    摘要： The present invention provides a security module having a communication interface being capable of operating according to any from a selection from a plurality of predetermined operation modes or communication protocols. The security module further comprises a voltage detector to detect the voltage on the module's power supply connection. Depending on the value of the detected voltage or to which of a plurality of predetermined voltage ranges the detected voltage may be categorized, the security module is made to function according to one from the plurality of predetermined communication protocols. According to an embodiment of the present invention the plurality of communication protocols require that the security module operate at a plurality of different frequencies.
