 This systematic literature review examined the existing research related to information security in chatbots, identifying potential threats, proposed solutions, and future directions for research. It found that chatbots face various security threats, including malicious input, user profiling, contextual attacks, and data breaches, and that solutions such as blockchain technology, end-to-end encryption, and organizational controls can be used to mitigate these concerns. Additionally, the review emphasized the importance of maintaining user trust and addressing privacy concerns for the successful adoption and continued use of chatbots. Finally, it identified future research directions that included developing more sophisticated authentication and authorization mechanisms, exploring the use of privacy-enhancing technologies, and improving the detection and prevention of security threats.
