Abstract
Keeping up data security is something everybody wants so that the security of data and information is one of the main elements of communication technology. Data security is one of the major threats to delivering data through the internet. Data security is concerned with protecting all sensitive data from unauthorized access [1]. The security threats are increasing with the increase of sensitive data and confidential information so that security issues should be taken into consideration because hackers or data thieves may use vulnerabilities over public networks to take the desired information. The sensitive data includes health care records, financial transactions [1] , and criminal justice records.
