An implementation of NISTPack Optimized for the
Microsoft Windows CE Operating System for Pocket PCs

The NISTPack Mobile library for Pocket PCs is an implementation of NISTPack optimized for mobile applications running on Windows CE. Like NISTPack, NISTPack Mobile includes FBI-compliant WSQ compression for fingerprints images and JPEG/JPEG2000 compression for facial images; both are performance-optimized for Windows CE. Also like NISTPack, it enables creating, editing and writing of image and text data files compliant with the ANSI/NIST Data Format for the Interchange of Fingerprint Information.

Functionality

Reading information from a transaction file This entails reading the file into an internal format and providing access to the transaction’s image and textual data. This might be done by users who wish to display the information contained in a transaction file. Creating a transaction file This entails building up a transaction from image and text information into a valid transaction file. This might be done by users who need to generate submissions of ten-print files or for any other type of transaction. Verification of a transaction file This entails examination of the transaction file for compliance with the general transaction format given by the ANSI/NIST specification or by a more specific implementation like the FBI’s EFTS specification or a state specific implementation. The user could determine if the transaction is compliant or if it is not, generate a detailed list of errors. Editing of transaction files This entails making changes to existing files or correcting items and assuring that the new file is compliant.
