Nowaday, to protect security information of users, the secure keyboard solutions are widely used and they are enhanced their security level by conducting with the extended end-to-end security environments. Along with the advance of secure keyboard solutions, malwares to leak secure information
of users also have been steadily advanced. Today, according to the requests of the secure keyboard solutions that do not use physical keyboards, the new secure keyboard solutions working on Javascript or hardware overlay have been developed and served. In this paper, we consider the several secure keyboard solutions and show their vulnerabilities through our experiments. In addition, we discuss the possible solutions for the vulnerabilities.
