INTRODUCTION
 The Fingerprint Recognition system is a new part of biomatrics.
 It provides an exciting look into the future.
 Basically devided into two types-
Enrollment
Recognition
Enrollment
 Enrollment can be further organized into three steps-
 Image Capture
 Signature Extraction
 Storage
Image capture
 Image capture consists of obtaining an image of the fingerprint.
 Typically, resolution is 500 dpi which corresponds to a pitch of 50 microns.
 In the real world, there are some systems that use only one bit per pixel or binary fingerprint images.
Signature Extraction
 Storing of images consumes much memory.
 So the fingerprint image is processed in order to obtain a signature or template.
 A template is a compressed version of fingerprint image,with losses.
 After passing the image through several filters only the relative coordinates of minutiae are stored which are very small in size.
 30 to 40 minutiae cost around 256 bytes.
A less compact technique from storage point of view is direrct optical correlation.
Storage
Once the template is obtained,it is stored for further recognition.
Recognition
 The Recognition Process follows the same steps as Enrollment with the addition of other.
 The process includes
 Image Capture
 Signature Extraction
Matching
 The Matching can be devided into two types
 One to one(Verification)
 One to many(Identification)
 One to one may be a kind of one to few.
 Verification takes less computing time than Identification hence vastly used in commercial application.
Fingerprint sensing Techniques
 There are different techniques for sensing the fingureprints such as
 Optical
 Ultrasound
 Silicon chip
 Optical Scanners
 Silicon sensors compared with others
SiliconConfusedize does matter
 Cost is very important factor when considering biometric technology.
 As far as Si is concerned lower the area lower is the price.
 Moreover lower the area lesser is the probability of defect.
Sweeping technique
 Unfortunately fingerprint imaging is very difficult for small Si chips.
 Hence the Sweeping technique has been devloped.
 Here the user have to sweep his/her finger over a thermal rectangular array.
 This method uses several lines per slice and search identical pixels between each slice.
Security
 The security may be devided into two parts
 Living security
 Electronic securityThe system on a chip
 The sensor ,processor,associated memory and reference storage may be planted on a single chip.
 But the limitation is the cost.
 We can implement ciphering techniques on the sensors as in smart-cards.
 But it may effect the security.
 Authentication
 We may use a smart card with the fingerprint signature reference and a device able to extract the signature.
 But the processor that performs matching may be corrupted.
 Hence the matching software must be written on the smart-card which results uncorrupted matching.
 Authentication
 This kind of smart card may be quite universal and unusable if stolen.
 But the only limitation will be the standardization of the software.
 It must be able to work with any fingerprint reader and variety of signature extraction softwares.
 Authentication
 A better system is a smart-card which performs the whole process i.e. image capture,signature extraction,matching with a single chip.
 It may overcome the standardization process but it has some limitations.
 Required CPU power.
 Cost of the card.
 Technical difficulties related to thickness of card
 Size of the silicon chip.
Conclusion
 Fingerprint sensing silicon chips are the future of inexpensive fingerprint imaging and help to increase security and efficiency.
 Use of CMOS components enables further system integration and hence greater security.
 High initial costs may slow the integration process but we can expect cost reductions and new possibilities with microelectronics.
