webserver - Fingerprint comparison with php -

-

i have small device scans fingerprints. there have image of fingerprint. hope can "bio-id" of fingerprint image , send id server. server side can execute php.

there compare "bio-id". in best case no php libraries required , "bio-id" can compared string. authenticate user, means have compare fingerprints.

it work on picture described:

enter image description here

is important on server side possible use php (no special configuration), great if fingerprint sent string , string can compared other strings without effort.

thank much

so assuming question "what next steps need in order system work".

well since have scanner (futronic fs88h), gives bitmap, have pass bitmap through algorithm changes string. mentioned in best case scenario wish not use library, more complicated if didn't. library collection of code has developed specific purpose. if don't want use function else created fingerprint string bitmap, have create yourself, million times more difficult.

my suggest be:

  1. find library has algorithm in change fingerprint string.
  2. install library server using
  3. create php functions
    • stores these fingerprint values database or whichever preferred method of storage
    • compares users fingerprint fingerprints in storage
    • deletes fingerprints stored

that should move forward

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
