Abstract
In this modern age, information technology has developed tremendously. This development becomes very fast as it is the best way to share information. Social media users' concerns about their privacy have spiked in recent years. Incidents of data breaches have alarmed many users and forced them to rethink their relationships to social media and the security of their personal information. There can be many risks to information sharing, which is considered an attack on software and information hacking. Today, the password has a threat to any security system. Hackers steal people's passwords and misuse them. Peoples are worried about hacking their information and data. In this paper, we present the analytic hierarchy process (AHP) approach under the environment of q-rung orthopair double hierarchy linguistic term set (q-RODHLTS) and its some fundamental operations. For this purpose, we use the q-RODHLAHP in the multi-attribute decision-making process. Examples of security systems are demonstrated to illustrate the validity of the proposed approach. Security has become a significant issue as information technology is spreading rapidly in our daily lives. Finally, numerical applications of the security system have been presented to show the validity of our proposed method.
