- The invention will become more apparent from the following detailed description of its embodiments taken in conjunction with the attached drawings in which:
-
FIG. 1 illustrates a first embodiment of a method for entering a password using a set of images that are dynamically displayed on a user's computer display; -
FIG. 2 illustrates a second embodiment of a method for entering a password using an image with a dynamically changing content displayed on a user's computer display; -
FIG. 3 represent in details the steps of a method for entering a password according to the second embodiment. - In a first embodiment of a method is accordance with the present invention (
FIG. 1 ), a user predetermines a number of screens, type of images to be displayed of each of the screens, a number of objects to be displayed on each of the screens, and an order and screen on which the objects of the dynamic image are to be selected. The user further determines which contact means (e.g. left or right button of a mouse or a certain key on a keyboard, etc.) will be used to point the time of appearance of a predetermined object on a screen. The predetermined object of the dynamic image is an object that has taken a user-conceived position in space and/or state in time. - The user can further determine which of the screens are significant for entering a password and which are not, i.e. which of the screens will be used to enhance security of the password entry. Respective user's settings are registered in software.
- According to
FIG. 1 , a user is suggested to monitor appearance of graphic objects, predetermined for creating a password, on a user-defined number of screens (four in this case). The time when a user-predetermined object appears on each screen is pointed via a selected contact means, e.g. by click of the left button of a mouse or by depression of a selected key on a keyboard. Contents of each screen may change periodically, any number of times according to the user's wish and at a selected rate. By way of example, a number of pictures periodically displayed on each screen is 20. A password can be defined by the user, e.g. as follows: appearance of a tiger on the right upper screen; appearance of a parrot on the left lower screen; appearance of a shark on the left upper screen; appearance of a butterfly on the right lower screen. This means that the first time mark made by the contact means is addressed to the right upper screen; the second one is addressed to the left lower screen; the third one is addressed to the upper left screen, and the forth one is addressed to the right lower screen, which corresponds to the user-defined order of selection of the objects on respective screens. A feature of the password entry is that when pointing the time of appearance of a predetermined object the process of displaying the objects will be continued until the password is completely entered. Nothing reveals the password entry process on the display, therefore, an unauthorized person could not know the appearance of which object and on which screen is being monitored by the user, i.e. the appearance of which objects on which screens and in which order is pointed by the user. - Functions of storing the entered parameters of the password entry dynamic image, comparing said stored parameters with parameters of the pointed objects of the dynamic image and, responsive to correspondence between the parameters, identifying the password are implemented in an appropriate software.
- The password entry process can be realized in a number of ways. First, selection of password objects is not mandatory on every screen, i.e. in determining a number of screens to be displayed the user may specify any number of significant screens, e.g. three. In this case, a password will consist of any three objects of the dynamic image. Second, a particular contact means may be selected to point the time of appearance of each of the objects. In this case, an exemplary password described above with reference to
FIG. 1 will be as follows. If the user's password corresponds to appearance of a tiger on the right upper screen, a parrot on the left lower screen, a shark on the left upper screen and a butterfly on a right lower screen, the user may point the time of appearance of a tiger via the left button, a parrot via the right button, a shark via the left button, and a butterfly via the left button of the mouse. Therefore, the user himself selects the security of his (or her) password and complexity of its memorizing. Third, when setting a password the user may select contact means insignificant for creating the password. That is the right button of the mouse is insignificant in the described password, hence, it does not affect the password entry when depressed. This further enhances the password protection from an unauthorized viewer—in addition to the fact that the viewer does not know the appearance of which object and on which screen is being monitored by the user, he (or she) does not know whether the appearance of this object is significant for the password, i.e. whether actuation of a certain contact means is significant for the password entry. - In another embodiment illustrated in
FIG. 2 , a user is suggested to monitor selected objects that are united in a dynamic (animated) image. According toFIG. 2 , objects shown in the displayed picture, such as a child, a ball, a fish and a butterfly, change their position in space, while an object, such as a bird, changes its state, i.e. is flying, without changing its coordinates. The time when the animated objects take a predetermined position in space or a predetermined state in time is pointed by the user via any one selected time pointing device (e.g. by click of a mouse or depression of a selected key on a keyboard). The user's password may correspond to the states of the animated objects at the instants when the fish is in water with its head (FIG. 3 a), the child sits still near the ball (FIG. 3 b), the ball appears on the screen (FIG. 3 c), the butterfly is above the rightmost umbrella (FIG. 3 d) and the bird's wings are up (FIG. 3 e). Therefore, the first time mark, e.g. the first click of the mouse, is addressed to the fish, the second one is addressed to the child, the third one is addressed to the ball, the forth one is addressed to the umbrella, and the fifth one is addressed to the bird, which must correspond to the user-defined order of selection of the animated objects. - A feature of the password entry is that when pointing the time of appearance of a predetermined object at a predetermined point of space or attainment by a predetermined object of a predetermined state in time, the process of displaying the animated objects will be continued until the password is completely entered. Nothing reveals the password entry process on the display, therefore, an unauthorized person will not know which position in space and/or state in time is being monitored by the user, and in which order they are pointed by the user. The animated objects are repeatedly displayed at the user-defined animation rate in the case the user has not managed to timely point a respective object in the predetermined position. All of the described features of password creation can be used: selection of all of the animated password objects on the dynamic object is not mandatory, i.e. when determining objects for the password entry the user may declare any objects to be significant.
- Such functions as selection of a state modification mode of each of the screens, determination of a state modification rate of each of the screens, determination of an object animation rate of the dynamic image, an order of selection of objects of the dynamic image on respective screens responsive to the user-entered indication as to which of the actuated means are significant for the password entry, are implemented by an appropriate software.
- To enter a password that represents a rhythmic pattern, the user must enter a predetermined rhythmic pattern via predetermined contact means. The rhythmic pattern may be a fragment of a music composition, and the contact means may be assigned functions of keys of a musical instrument.
- By way of example, a user selects the left and right buttons of a mouse as a password entry device. The user's password can be set as follows: three depressions of the left button, two depressions of the right button, three depressions of the right button, two depressions of the left button, three depressions of the right button, one depression of the left button, one depression of the right button, one depression of the left button, one depression of the right button, and two depressions of the left button. Such a seemingly difficult-to-memorize password represents a popular melody, “Dog's waltz”, played on two keys of a key-driven musical instrument. The password is hard to oversee and repeat, as the user's hand fully covers the mouse, and the fingers stay constantly on both contact means—it is difficult to realize which button of the mouse is depressed and how many times. Only the user knows the key melody which facilitates memorizing the password as a respective rhythmic pattern, and the number and order of actuations of each of the selected contact means. In creation of such a password, the user may select as contact means for the password entry any means from the group including keyboard keys, mouse buttons and combinations thereof, as well as combinations of contact means having identical functions. By way of example, to enter the aforementioned password the user may select the upper (numeric) row of the keyboard instead of the left mouse button, and the right field of the keyboard, also numeric, instead of the right mouse button. In the process of the password entry, each button in every group of buttons has identical meaning. Therefore, it is not important which of the buttons in the group is depressed, only the group—right or left—to which it belongs is of importance. This method of entering a password enhances protection from an unauthorized viewer, because the viewer not only does not “hear” the rhythmic pattern being entered, but does not know either which of the contact means corresponds, by its meaning, to each element of the code. The rhythmic pattern code may contain any number of “sounds”, i.e. depressions of the contact means, depending on the user's ability to memorize it.
- The user-entered rhythmic pattern is compared with the pre-stored rhythmic pattern and the password is identified responsive to correspondence between them. These functions can be implemented by a software.
- In an embodiment, a rhythmic pattern may be entered as a combination of long and short actuations of user-defined contact means.
- The process of entering a password in the form of a rhythmic pattern is not accompanied by displaying any images on the screen, and access to a computer database cannot be gained until the password is completely entered.
- The password entry using a dynamic picture possesses the following advantages: a great number of possible combinations can be created as each of the animated objects may take a sufficient number of easily memorized positions; protection from an unauthorized person, an intruder, can be enhanced by any one of the described means or combinations thereof. Therefore, a method for entering a password in accordance with the invention overcomes basic problems encountered by the user in selection, memorizing and protection of his (or her) password for gaining access to computer databases.
- The password entry using a rhythmic pattern possesses the following advantages: a great number of combinations created on the basis of popular melodies and rhythms provide easy and simple memorizing a password by user; methods for entering rhythmic patterns additionally enhance protection from an unauthorized viewer.
- The present invention can be used to create means for entering a password to access computer databases, to provide secure access to mobile telephones, terminals of financial transaction systems, as well as in security systems of protected territories equipped with video monitors.
