II. FINGERPRINT SCAN TECHNOLOGY

There are five vital stages of the fingerprint scan technology

which are the fingerprint image acquisition, image
processing, and location of distinctive characteristics,
template creation, and template matching. The main aim of
fingerprint-scanning technology is to acquire the good
quality of fingerprint which can be further used. Fingerprint

Everyone has unique fingerprints across individuals, and

across fingers of the same individual. Traditionally,
fingerprint patterns were taken by the ink impression on the
paper which was then matched and verified. The electronic
era has ushered in a range of compact sensors that provide
digital images of these patterns. Mouse and keyboards
computer peripherals act like the sensor which is used to
incorporate the data into the computer, thus making the
mode of identification a very attractive proposition thus
authenticating the fingerprint based system.
B. Techniques of Matching Fingerprints

The different techniques of fingerprint matching include:

1) Correlation-based matching: Two fingerprint images

• Unique- Everyone has the different and unique
fingerprint. Fingerprints have loops and arches which
vary from person to person.
• Accurate- The information obtained from the
fingerprints is accurate as it different to every person
and is easily comparable with the candidate fingerprint
images stored in the database.
• Small storage space- The memory required to store the
fingerprint template is small and requires less memory
space.

B. Disadvantages:

• False Readings- Lower cost biometric systems leads to

errors thus hampering the authorized person from
accessing the personal confidential data.
• Costly- Biometric system is costly which is not easily
affordable and eliminate many from using it.

IX. CONCLUSION

The Fingerprint Based Patient System was specifically

developed for storing, monitoring and analysing the patient
medical reports. The system uses the fingerprint scanner for
retrieving the patient details from the system. This system
will allow users to access hospital’s information anytime.
The integrated database, single it TEAM all means lower
cost of operation, maintenance and upgrade and a significant
reduction in total cost of ownership. This also makes
expanding to a new location a breeze as the additional IT
investment is minimal.
