please i need help to save a captured fingerprint on java to sql database its my project and defense is Thursday.
am using u are u sdk please help please am stranded. if there are other means please let me know

Desyner:
In what format do you have the finger print ? If in image (jpg, jpeg, png, gif) format follow what the above guy said. If you are stuck, let's know.

raymod170:
1. create a field in your database table name it fingerprint or whatever
2.the property of that field should be in blob(Binary Large OBject)
3.on your IDE create a function call it savefingerprint
4. write a few lines of code that converts the image to byte array
5. then once you have achieved that you write an sql statement that saves to the database field it's that simple mind you it's saving the image as an array.
6.if you have more questions ask here or make stack overflow your bestfriend as well

blessedemperor:


thank sir, please if i save as image will i be able to call it for verification?

blessedemperor:

thank you sir

i am saving it to later call it for verification, i am pretty new to java. in fact i dont know to code in java but my supervisor insisted i use java. please if i save it as image will i be able to verify it

This is technical but your api provided by the fingerprint scanner you using should be able to provide a solution for you

but wait a minute you didn't ask the right questions at all you saving an image and verifying that image Is different from just saving and reading the image

you have to work with a template which is created and stored on the system as well which would be used to verify the already stored image after you must have converted back from byte array to the actual image itself

are you saving any other fields like name, sex or phone number make one of them a unique key and then use it to save the template created after saving to the database

during verification what happens is the image which you saved should be created to a template and used to match the initial created template of the user which you saved on your system using a unique identifier if the two matches then it's valid else it's not

but this isn't a walk in the park you must use the api provided by the fingerprint scanner as well

and try and improve on your Java as well

besides what have written if not rubbish as its best

lol

best regards

Desyner:

In what format do you have it, for example some files are mp4 or mp3 cos the end with .mp4 and .mp3 respectively. What do you save it as ? Is it .jpeg, .jpg, .png, or .gif. I need to know that or describe it in details.

Jenifa123:

It is difficult but it's possible to verify it if it's saved as an image

blessedemperor:


The image or template is captured from u are u 4500 and displayed on jlabel.
Thank you

blessedemperor:


I got a code to capture the fingerprint and the display it on a jlabel. Then from there I don't know what next to do that's why I am serious running around for help. And there are limited resources online. Meanwhile I have never written a block of code in java. So I can't even tell which part got the template and send it to the jlabel. I have other fields and saving and registration number is the primary key

Desyner:
if I get u right, you have it displayed on ur screen in a software called 'u-are-u-4500' and you want to save it to a database directly ?

raymod170:



Dude am one thousand miles from you and am still running away..... your reply just got me confused on all levels are you saying you haven't written any code as well then how do you even want someone to help you when you don't know how to implement those simple guide I mentioned before


I will advise you outsource the project and learn from the person you outsource to that way you learn better and faster than this

remember you have limited time as well

best regards

Yes sir

Yes sir

israelboy1:
I have worked on this before...as well as the authentication part.

What's the challenge you are still facing

blessedemperor:


I have tried to outsource but can't get who will help please if you know who can, can you please recommend?

demolinton4comi:
I don't knw why we Nigerians behave like this.... Somebody will need help u will be dropping phone number to reach u privately please it very important for others to learn........ My advice is for you to check the documentation of the u and u 4500 you will see how to convert the fingerprint to byte then u can insert the byte into sql database. OR u can further more by converting the byte to long text (string) the u can insert the string to sql

Desyner:
I was expecting the guy to sample the doc or his project so i can extract the byte[] for him and point the rest out to him but . . .

blessedemperor:


But what sir?

micodon:
never save blobs on your rdbms. save the fingerprint image somehwere on disk and save the filepath in a column in the user table on the db for reference

raymod170:


kindly explain why you made such suggestions.However I save all my images to my databases cos its easier when working on complex systems that can be accessed remotely so as to avoid runtime errors.... I must admit when I started out programming saving to a folder was one of my major codes achievements lol � but to be honest as a software gets more and more complicated you have to upgrade your algorithms to match such software's to avoid issues overtime which may occur most especially handling images, data structures and runtime errors
