RFID-based system for tracking billable anesthesiology time in a surgical environment employs hand-held RFID reader devices that record and store timed anesthesia events for each surgical patient. Each patient is assigned a reader device, uploaded with patient data. Each anesthesiology professional has an identifying RFID transponder, and room transponders are located on wall or doorway of each room in the surgical suite. A download cradle is used for downloading the patient data collected during surgery to a central computer. The reader devices are synchronized to a high-accuracy clock, eliminating time accounting problems associated with concurrency and discontinuous time.

A method and apparatus for determining a class signature from an article made of paper or cardboard in order to identify a generic type of class to which the article belongs. An optical beam illuminates the article and a detector arrangement collects data points from light scattered from many different parts of the article as the article is scanned by the beam. The class signature derives from intrinsic properties imparted to the paper / cardboard during manufacture by, it is believed, the screen used during dewatering of paper pulp. Detection of the class signature allows the manufacturer or the particular paper making machine that made the paper to be identified.

A vending machine uses a field-programmable electronic lock that learns a key code from a corresponding electronic key. The electronic lock has a learning process activation device that is accessible when the door of the vending machine is in the open position. Using the learning process activation device, a service person activates the electronic lock to perform a key code learning operation, in which the electronic lock receives a key code transmitted from an electronic key and stores the key code in a non-volatile memory for future access control of the vending machine. Data encryption is employed in the communications between the key and the lock to ensure the security of the communications. A communication device installed in the vending machine for communicating with a home base computer allows the operation of the electronic lock to be remotely controlled for access control and auditing purposes.

Consumers of content protected multimedia data, such as e.g. commercially available video DVDS, want to take backup copies of these data, and want to be free to play the data on any suitable playback device, while content providers want to protect these data against pirate copying. The disclosed method for accessing application data from a first storage medium, e.g. CD, uses an electronic key for decoding or converting the application data. One or more content identifiers are attached to the application data or the first storage medium. The key is stored on a copy-protected separate second storage medium, e.g. RFID tag, and compared with the content identifier. Playback or format conversion of the application data is only possible when the second storage medium is available. This allows the application data to be copied, distributed or format converted, while simultaneously preserving the content rights of the data because only one copy can be used at a time.

An integrated security structure is provided employing an external source of energy to change the appearance of the structure rendering the structure more challenging to duplicate due to its complexity. The security structure includes a substrate forming part of a bank note, identification document, or other security device; an active device within the substrate changing color between at least two colors wherein a color of the substrate surrounding the active device matches one of the at least two colors to form a metameric device. At least one Interference Security Image Structure (ISIS) is configured to be metameric with a bleached state of the active device and is therefore invisible at normal incidence. Another ISIS is metameric with the colored state of the electrochromic device and consequently becomes invisible during coloration. When the whole device is tilted, both ISIS's change color while the rest of the device essentially remains the same.

The invention discloses a data encryption method and system. The data encryption method comprises the steps of obtaining a cipher key which is generated according to fingerprint information of a current user when the current user conducts encryption or decryption operation to data; and encrypting or decrypting the data by using the cipher key. Since the fingerprint information of users is different, the cipher keys which are generated according to the fingerprint information are different, i.e. each user owns a unique cipher key and further owns a unique data encryption method. The cipher key is generated according to the fingerprint information through a preset rule in terminal systems. Even though the finger information of the users is illegally copied and stolen, encrypted files in the terminal systems cannot be decrypted in other systems, so that the security of user data is greatly improved.
