I have been searching on google but no luck, I downloaded a source code that does this:
- capture picture and upload to server, this work perfectly fine.
However, I wish to compare the picture with a picture in a database for user clock in. In order to do this, a picture of the user must be already stored in the database, and then everyday, when clock in, the capture picture is compared with the picture in the database (not sure how the two pictures can be compared. binary maybe)
Please help if you have any link to a solution or an idea. Thank you in advance.
Prefer php code, if not any would be ok
