Abstract:
A system and method for performing a security check may include using at least one processor to periodically check a status of a flag, generate and store a baseline representation of modules stored on the device where the flag is determined to be set to a first state, and, where the flag is determined to be set to a second state, generate an active representation of modules stored on the first device, compare the active representation of modules to the baseline representation of modules, and, responsive to a determination in the comparing step of a difference between the baseline and active representations of modules, output an alert. The flag status may depend on an association of the device with one of a plurality of authorization policies, each mapped to one of the two states. Results of the comparison may be appended to an activity log of the device.
Abstract:
Disclosed is a storage device which includes a nonvolatile memory device including a memory block a program order of which is adjusted regardless of an arrangement of memory cells, and a memory controller that performs address mapping to replace a bad page of the memory block with a normal page of the memory block.
Abstract:
The present invention relates to a transfer jig for a bracket or a tube to perform an orthodontic operation to an actual tooth of a patient by an indirect attachment using an electronic mold, the transfer jig comprising a fixing unit which has a fixing base including a contact surface corresponding to the actual teeth; and a moving unit which has a first side coupled with the fixing unit and a second side detachably attached to at least one of the bracket and the tube. That is, the fixing unit is manufactured by a small/high precision CNC equipment installed in individual dental clinics. The moving unit is attached to a slot of the bracket or tube in the same direction as the coupling direction of the arch wire. The moving unit is rotatably coupled with the fixing unit.
Abstract:
A method and system for providing controlled access to information stored on a smartcard. The system includes a data processing center maintained by a trusted third party for storing a database of authorizations of various service providers to access information pertaining to individuals, and for responding to request by service providers for access from terminals which communicate with the data processing center and smartcards storing the individuals' information. The information is stored on the smartcard in encrypted form and the data processing center provides an access code, which includes a key for decrypting the information, only to service providers who are authorized to access the information. The service provider then sends the access code to the smartcard which verifies the access code and decrypts and outputs the requested information. The smartcard then computes a new key as a function of information unique to each access session and uses the new key to re-encrypt the information, and then erases the new key. The data processing center also computes the new key so that the data processing center can provide an access code including the new key for the next request for access.
