Abstract: Current CAPTCHA tests are designed to be difficult for a bot and simple for a human-user to answer; however, as artificial intelligence improves, bots are more capable of using techniques such as optical character recognition to resolve current CAPTCHAs in similar manners as human-users. By maintaining a library of security tests and/or questions based on products purchased by the human-user, and using those questions as a CAPTCHA challenge in order to determine if the user is a human-user on how the user responds, CAPTCHA challenges may be directed toward determining a human-user based on responses exhibiting humanity.

Abstract: Disclosed are systems and methods for controlling execution of programs on a computer. An exemplary method includes detecting an unknown program installed on a computer; identifying undesirable actions performed by the unknown program on the computer, wherein the undesirable actions include at least one of: actions performed by the program without knowledge of a user, actions for accessing personal user data on the computer, and actions effecting user's working with other programs or operating system of the computer determining whether the unknown program is undesirable or not based on the identified undesirable actions of the program; when the unknown program is determined be undesirable, prompting the user to select whether to allow or prohibit execution of the undesirable program on the computer; and when the unknown program is determined not to be undesirable, allowing execution of the unknown program on the computer.
