Zusammenfassung:	An embodiment of the invention is a CAPTCHA program to determine if a user of a computer is a human or a computer program. The program sends to the computer an image and a portion of the image for display. The program receives from the user an indication of where the portion is located within the image. The portion, as displayed, may be altered in various ways. In response to the user properly indicating the location, the program determines that the user of the computer is a human. In response to the user not properly indicating the location, the program determines that the user of the computer is a computer program. In response to determining that the user of the computer is a human, the program grants the user access to information (database, application, program). In response to determining that the user is a computer program, the program denies access.
