摘要： A kernel based detection of keyboard logger applications is achieved by configuring a call interface to the kernel to characterize a system call pattern for processes accessing a keyboard. A monitor thread iteratively examines a plurality of threads to test open( ), read( ), write( ), and syscall( ) system routines for conditions indicative of presence of a keyboard logger application. A thread whose system call pattern is characterized by such conditions is marked as a keyboard logger.

摘要： A method for time stamping a digital document employs a two-part time stamp receipt. The first part of the time stamp receipt includes identifying data associated with a document and a nonce. The second part of the time stamp receipt includes a time indication and the nonce. The nonce serves as a link between the first and second parts.

摘要： A method for time stamping a digital document is disclosed. The document originator creates a time stamp receipt using the document and the current time. The time stamp receipt is submitted to a time stamping authority having a trusted clock. The time stamping authority validates the time stamp receipt by comparing the time value specified in the time stamp receipt to the current time. If the time value specified in the time stamp receipt is within a predetermined time window, the time stamping authority cryptographically binds the time value and document, or the time value and some representation of the document, e.g., by signing the time stamp receipt with its private signature key.

摘要： Embodiments of the present invention provide systems, articles of manufacture and methods for a telematic parametric speed metering system. In one embodiment, a system may determine a vehicle's location and speed. Once the location has been determined, corresponding geographical zone based speed limits and/or other information may be acquired via internal memory or data transmission. The speed of the vehicle may then be compared against the speed limits for the zone. If the vehicle's speed exceeds those speed limits, one or more of a plurality of actions may be performed including (but not limited to) warning the driver via a visual or audio signal, informing an authority agency via data transmission, logging the excessive speeding condition (e.g., time, date, speed, location, driver name, etc).

摘要： System and method for recording temperature on an RFID tag. A first RFID tag is attached to a container. The first RFID tag includes a temperature sensor. The container contains a multiplicity of packages. A multiplicity of second RFID tags are attached to the multiplicity of packages, respectively. The first RFID tag transmits temperature information to the multiplicity of second RFID tags. In response, the multiplicity of second RFID tags record the temperature information. Consequently, there is no need for expensive temperature sensors on the multiplicity of RFID tags on the packages. According to features of the present invention, the first RFID tag is an active RFID tag, and the multiplicity of second RFID tags are passive RFID tags. The first RFID tag also transmits other information to the multiplicity of second RFID tags to enable the second RFID tags to authenticate the temperature information. Other types of environmental sensors such as a humidity sensor or vibration sensor can substitute for the temperature sensor.

摘要： A Resource Reservation System includes a Token Generation Unit (TGU) which generates and circulates among nodes of a communications system a Slotted Token (SLT) message having sub-fields to carry identification number for each input port in a node and the resource available for each input port. On receiving the message the Resource Control Unit (RCU) in each node can write port identification number, available resource in appropriate sub-fields of the SLT message, and reserve resources in other nodes by adjusting information in the sub-field associated with the other nodes.

摘要： System, method and computer program for authenticating a user of a client computer to a remote server computer. A client computer initially sends a userID but not a password of the user to the remote server computer. In response to the userID, the server computer determines a subsequent time window during which the server computer will consider for authentication submission of a combination of the userID and a password. The server computer notifies the client computer of the time window. After receipt of the notification from the server computer, during the time window, the client computer sends the userID and a corresponding password to the server computer. In response to receipt of the userID and the corresponding password from the client computer, the server computer determines if the combination of the userID and the corresponding password is valid. If the combination of the userID and the corresponding password is valid, the server computer notifies the client computer that the combination of the userID and the corresponding password is valid. In response, the client computer establishes a session with the server computer and accesses a resource requiring a valid combination of userID and password to access. The server computer ignores combinations of userIDs and passwords submitted before or after the time window.

摘要： A method for time stamping a digital document is disclosed. The document originator creates a time stamp receipt by combining the document or other identifying data and a digital time indication. The time stamp receipt is submitted to a time stamping authority having a trusted clock. The time stamping authority optionally validates the time stamp receipt and then computes the age of the time stamp receipt. The time stamping authority creates an aged time stamp receipt by combining the identifying data and time indication contained in the submitted time stamp receipt with the computed age of the time stamp receipt. The time stamping authority cryptographically binds the time information and identifying data in the aged time stamp receipt, e.g., by signing the combination of the identifying data, time indication, and computed age with a private signature generation key.
