31、biometric technologies have existed for many years. Additionally, new technologies employing palm crease images obtained from hands are emerging or under continuous improvement as a result of new, state-of-the-art imaging devices for mobile applications or web services. Currently however, palm creas
32、e biometric image information is being exchanged between the equipment and devices from different vendors without standardized format is the problem. This is due in part to the lack of standardized formats for information exchange that would ensure interoperability among the various vendors. The pur
33、pose of this document is to define a standard for the exchange of human palm crease biometric image information. The standard defines specific attributes, a data record format for storing and transmitting palm crease biometric images and certain attributes, a sample record, and conformance criteria.
34、 This document is intended for applications requiring the exchange of raw or processed palm crease biometric images. It is intended for applications not limited by the amount of storage required. It is a compromise or a trade-off between storage and quality and can be resolved by standardized format
35、. It enables various algorithms to identify or verify the palm crease biometric image data transferred from other image sources. Currently, available palm crease biometric technologies that may utilize this document for image exchange are technologies that use palm for mobile applications for identi
36、fy verification or web services. The use of captured source images can provide interoperability among and between vendors relying on various different recognition or verification algorithms. Accordingly, data from the captured palm crease biometric image offers the developer more freedom in choosing
37、 or combining a comparison subsystem In this document, Annex A contains the conformance testing methodology and Annex B contains the XML schema. Annex C contains the XML sample program.

38、 data interchange format Part 15: Palm crease image data 1 Scope This document specifies an image interchange format for biometric person identification or verification technologies that utilize human palm crease biometric images and can be used for the exchange and comparison of palm crease image d
39、ata. It specifies a data record interchange format for storing, recording, and transmitting palm crease biometric information from palm crease imaging. It defines the contents, format, and units of measurement for the image exchange. The format consists of mandatory and optional items, including sca
40、nning parameters, compressed or uncompressed image specifications and vendor-specific information. Information compiled and formatted in accordance with this document can be recorded on machine-readable media or may be transmitted by data communication facilities. 2 Normative reference The following
