The disclosure describes systems for creating and authenticating printed objects using authentication and copy detection watermarks. For example, one verification system includes a watermark decoder and a verification module. The watermark decoder detects a copy detection watermark in a printed object to determine whether the printed object has been reproduced. The verification module processes a message decoded from an authentication watermark on the printed object to authenticate the printed object or bearer of the printed object. The authentication and copy detection watermarks may be implemented as the same or different watermarks. For example, the copy detection watermark may be a fragile watermark that carries the message and that degrades in response to a reproduction operation, such as photocopying or scanning and then reprinting the object. Alternatively, the authentication and copy detection watermarks may be separate watermarks embedded in an image that is printed on the object. The authentication watermark, in some applications, includes an identifier that links the object to a database entry with related information about the object. This related information can be used to check the bearer of the object by comparing it with attributes of the bearer (such as a user ID or photo) or the validity of the object by comparing it with attributes that are visible or machine readable on the object.

A data processing apparatus having one or more trace data sources is provided in which the trace data sources operate to generate respective streams of trace data. At least one of said trace data sources comprises a trace data generator responsive to activity in monitored circuitry to generate trace data representing said activity. A synchronization marker generator is coupled to the trace data generator and operates to generate a synchronization marker and insert the synchronization marker into the trace data stream. The synchronization marker identifies a synchronization position in the trace data stream. A controller is coupled to the synchronization marker generator, and operates to initiate the synchronization marker generator to generate and insert a synchronization marker into the trace data stream. The controller controls initiation in dependence on behavior of the data processing apparatus downstream of the trace data generator with respect to trace data flow. In this way, the downstream behavior of the data processing apparatus can be made to influence the rate and timing of insertion of synchronization markers into a trace data stream, thereby reducing the likelihood of the volume of trace data resulting in an overflow condition in the downstream circuitry.

In standby mode, memory contents are saved to a hard disk. After AC power has been removed by disconnecting the AC plug, when the AC power is restored the data saved on the hard disk is automatically restored into memory to set the power-saving mode back to the standby mode. When the power is turned on next, quick resumption from standby mode can be accomplished.

A Surface Movement Area/Runway Traffic and Surface Area Flow Tool with Runway Incursion Protection System reduces runway incursions due to lost or disoriented aircraft, navigation in low visibility conditions, unfamiliarity with local procedures and airport layouts, and truncated or misunderstood clearances or other frequency congestion related communication and workload problems. SMART Board surface displays are used to provide route guidance instructions to aircraft at ramp and taxiway intersections, confirm to for pilots that their aircraft is at the correct location and is in the assigned queue and sequence before entering active runways, visual confirmation of runway clearances to aircraft and vehicles at all runway entrances, and lessening frequency congestion on Ground and Local communications channels. The system includes an Electronic Flight Data System to generate messages. Sensors and a wireless LAN are used to provide data from the system to all aircraft and vehicles on the surface movement area of an airport.

A health care worker is able to manually input data by zooming a graphical representation of vital data, moving a cursor at a predetermined position using a mouse or the like, and clicking the mouse. If it is confirmed that the value can be correct, then a setting button is clicked. Alternatively, it may be canceled. For the cancellation, a click button is clicked. By the way, it can be also observed as an output on a monitor (Steps from S11 to S16). In this case, the fact of being confirmed is displayed over the screen on which the monitor output of the vital data is displayed.

A method for improving the security of secret authentication data during authentication transactions is provided that includes converting the secret authentication data of a user into scrambled secret authentication data by associating a different text-string with each item of information included in the secret authentication data. The method also includes capturing the scrambled secret authentication data with a communications device, and conducting an authentication transaction with the captured authentication data.

Functional data for use in one or more digital transactions is secured by using an encapsulated security token (EST). In certain embodiments, the EST is created by encapsulating digital data including the functional data using at least two digital signature systems of two parties. The encapsulation and subsequent de-encapsulation can utilize digital signature systems of the parties that involve a private key for encapsulation and a public key for de-encapsulation. If constructed carefully over a series of rigorous events, the resulting EST can be practically impossible to counterfeit. In addition, a propagation of rights can be tracked for auditing and rights can be easily terminated or modified.

A computer system and method for securing files in a file system equipped with storage resources that are accessible to an authenticable user operating with an untrusted client device under the semi-trusted client threat model. The file to be secured is stored in one or more blocks belonging to the storage resources along with symmetric per-block key(s) KB_i assigned to each of the blocks in the file. The blocks are encrypted with the symmetric per-block keys to obtain encrypted blocks. The user is assigned user key(s) and each per-block key that was used for encryption is in turn encrypted with one of the user's keys to derive wrapped key(s) for each encrypted block. Wrapped key(s) are placed in encrypted block headers and introduce a level of indirection to encrypted file(s) that is appropriate for the semi-trusted client threat model.
