User application has been developed with very rapid progress. Security vulnerabilities due to amendment of escape characters and comment characters with the actual keywords becomes predominant in the current IT environments. There are some malicious attacks which can deceive this SQL. To stop string literal escape characters injections, many techniques have been proposed but they require large code modification and/or large extra time overhead. The work of this paper proposes a technique SQL Injection Protector for Authentication (SQLIPA) with the help of removal of SQL query attribute algorithm.
