       BACKGROUND 
       [0003]    1. Field 
         [0004]    This invention relates to secure access codes, and particularly to methods, systems and computer program products for creating secured access codes via continuous information. 
         [0005]    2. Description 
         [0006]    In conventional authentication systems based on access codes, the code is created by the user by choosing a sequence of discrete elements. Such elements are for example numbers in pin codes, letters/characters in passwords or pass phrases, in some implementation they can also be parts of images that are designated by the user. 
       SUMMARY 
       [0007]    Exemplary embodiments include a method for generation of a secure access code from a menu on the display, the method including retrieving a continuum of objects from a memory of a computer, presenting the continuum of objects on a computer display, receiving a menu selection entry signal indicative of the selection device pointing at a selected range from the continuum of objects, in response to the signal, storing the selected range from the continuum of objects in the memory, presenting a verification continuum of objects on the display, receiving a menu selection entry signal indicative of the selection device pointing at an object from the verification continuum of objects as a access code, in response to the signal, storing the selected object from the verification continuum of objects in the memory, comparing the selected object from the verification continuum of objects to the selected range from the continuum of objects; and in response to the selected object falling within the range of the continuum of objects, authenticating the access code. 
         [0008]    System and computer program products corresponding to the above-summarized methods are also described and claimed herein. 
         [0009]    Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention. For a better understanding of the invention with advantages and features, refer to the description and to the drawings. 
       Technical Effects 
       [0010]    As a result of the summarized invention, technically we have achieved a solution which, instead of using discrete information (such as numbers, letters or signs), the methods, systems and computer program products described here implement continuous information. The user therefore inputs access information that implements personal perception and appreciation, that is, something personal and related to the physiology/biology/history of the user, which is not easily reproduced.

       [0022]    The detailed description explains the preferred embodiments of the invention, together with advantages and features, by way of example with reference to the drawings. 
       DETAILED DESCRIPTION 
       [0023]    Exemplary embodiments include methods systems and computer program products that present a set of objects to a user who perceives that the objects are continuous, as opposed to discrete as in conventional systems. In exemplary embodiments, an underlying framework selects discrete objects, which can be high in number such that the user perceives a continuum. For example, the user can be presented with a continuum of color (e.g., a rainbow). If asked to point out, “pale blue” the user may select one location while another user may select a separate location. However each user is able to say precisely where for the particular user, “pale blue” starts and ends. As such, if the user desires to use the color, pale blue, as a access code, when the user selects the access code for the first time, the user specifies to the system where the limits of pale blue are in the presented continuum (e.g., to position two cursors on the start and end of where the color, pale blue”, is for the user). Then the next time, to enter the access code, the user positions a cursor via a mouse, for example, within the limits that the user mentally visualizes the color pale blue, and clicks in order to enter the “access code”. 
         [0024]    In exemplary embodiments, to increase security, the user can be presented several of colors (for example four colors). Thus, the access code that the user memorizes can be, for example, “pale green, bright orange, dark red, turquoise”. Even if an onlooker observes the user clicking the access code, the onlooker is only be able to perceive a general idea of the sequence of the access code (green, orange, red, blue) but not precisely enough to be able to recreate it the actual sequence. Currently, an onlooker can view a user typing a discrete password on a keyboard. An onlooker can have a better chance of seeing a discrete set of keys types rather than perceiving the same click sequence on a continuum of colors due to different perceptions of different people. 
         [0025]      FIG. 1  illustrates an exemplary embodiment of a system  100  for creating secure access codes via continuous information. The methods described herein can be implemented in software (e.g., firmware), hardware, or a combination thereof In exemplary embodiments, the methods described herein are implemented in software, as an executable program, and is executed by a special or general-purpose digital computer, such as a personal computer, workstation, minicomputer, or mainframe computer. The system  100  therefore includes general-purpose computer  101 . 
         [0026]    In exemplary embodiments, in terms of hardware architecture, as shown in  FIG. 1 , the computer  101  includes a processor  105 , memory  110  coupled to a memory controller  115 , and one or more input and/or output (I/O) devices  140 ,  145  (or peripherals) that are communicatively coupled via a local input/output controller  135 . The input/output controller  135  can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The input/output controller  135  may have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components. 
         [0027]    The processor  105  is a hardware device for executing software, particularly that stored in memory  110 . The processor  105  can be any custom made or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the computer  101 , a semiconductor based microprocessor (in the form of a microchip or chip set), a macroprocessor, or generally any device for executing software instructions. 
         [0028]    The memory  110  can include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and nonvolatile memory elements (e.g., ROM, erasable programmable read only memory (EPROM), electronically erasable programmable read only memory (EEPROM), programmable read only memory (PROM), tape, compact disc read only memory (CD-ROM), disk, diskette, cartridge, cassette or the like, etc.). Moreover, the memory  110  may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory  110  can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor  105 . 
         [0029]    The software in memory  110  may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example of  FIG. 1 , the software in the memory  110  includes the continuous information access code creation methods described herein in accordance with exemplary embodiments and a suitable operating system (OS)  111 . The operating system  111  essentially controls the execution of other computer programs, such continuous information access code creation systems and methods described herein, and provides scheduling, input-output control, file and data management, memory management, and communication control and related services. 
         [0030]    The continuous information access code creation methods described herein may be in the form of a source program, executable program (object code), script, or any other entity comprising a set of instructions to be performed. When a source program, then the program needs to be translated via a compiler, assembler, interpreter, or the like, which may or may not be included within the memory  110 , so as to operate properly in connection with the OS  111 . Furthermore, the continuous information access code creation methods can be written as an object oriented programming language, which has classes of data and methods, or a procedure programming language, which has routines, subroutines, and/or functions. 
         [0031]    In exemplary embodiments, a conventional keyboard  150  and mouse  155  can be coupled to the input/output controller  135 . Other output devices such as the I/O devices  140 ,  145  may include input devices, for example but not limited to a printer, a scanner, microphone, and the like. Finally, the I/O devices  140 ,  145  may further include devices that communicate both inputs and outputs, for instance but not limited to, a network interface card (NIC) or modulator/demodulator (for accessing other files, devices, systems, or a network), a radio frequency (RF) or other transceiver, a telephonic interface, a bridge, a router, and the like. The system  100  can further include a display controller  125  coupled to a display  130 . In exemplary embodiments, the system  100  can further include a network interface  160  for coupling to a network  165 . The network  165  can be an IP-based network for communication between the computer  101  and any external server, client and the like via a broadband connection. The network  165  transmits and receives data between the computer  101  and external systems. In exemplary embodiments, network  165  can be a managed IP network administered by a service provider. The network  165  may be implemented in a wireless fashion, e.g., using wireless protocols and technologies, such as WiFi, WiMax, etc. The network  165  can also be a packet-switched network such as a local area network, wide area network, metropolitan area network, Internet network, or other similar type of network environment. The network  165  may be a fixed wireless network, a wireless local area network (LAN), a wireless wide area network (WAN) a personal area network (PAN), a virtual private network (VPN), intranet or other suitable network system and includes equipment for receiving and transmitting signals. 
         [0032]    If the computer  101  is a PC, workstation, intelligent device or the like, the software in the memory  110  may further include a basic input output system (BIOS) (omitted for simplicity). The BIOS is a set of essential software routines that initialize and test hardware at startup, start the OS  111 , and support the transfer of data among the hardware devices. The BIOS is stored in ROM so that the BIOS can be executed when the computer  101  is activated. 
         [0033]    When the computer  101  is in operation, the processor  105  is configured to execute software stored within the memory  110 , to communicate data to and from the memory  110 , and to generally control operations of the computer  101  pursuant to the software. The continuous information access code creation methods described herein and the OS  111 , in whole or in part, but typically the latter, are read by the processor  105 , perhaps buffered within the processor  105 , and then executed. 
         [0034]    When the systems and methods described herein are implemented in software, as is shown in  FIG. 1 , it the methods can be stored on any computer readable medium, such as storage  120 , for use by or in connection with any computer related system or method. In the context of this document, a computer readable medium is an electronic, magnetic, optical, or other physical device or means that can contain or store a computer program for use by or in connection with a computer related system or method. The continuous information access code creation methods described herein can be embodied in any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. In exemplary embodiments, a “computer-readable medium” can be any means that can store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer readable medium can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: an electrical connection (electronic) having one or more wires, a portable computer diskette (magnetic), a random access memory (RAM) (electronic), a read-only memory (ROM) (electronic), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory) (electronic), an optical fiber (optical), and a portable compact disc read-only memory (CDROM) (optical). Note that the computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via for instance optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory. 
         [0035]    In exemplary embodiments, where the continuous information access code creation methods are implemented in hardware, the continuous information access code creation methods described herein can implemented with any or a combination of the following technologies, which are each well known in the art: a discrete logic circuit(s) having logic gates for implementing logic functions upon data signals, an application specific integrated circuit (ASIC) having appropriate combinational logic gates, a programmable gate array(s) (PGA), a field programmable gate array (FPGA), etc. 
         [0036]    Exemplary embodiments for entering a new code and setting of an access code are now discussed. In current systems, a code is a series of “object” designated by the user in sequences. The way of designation can vary. For example entering a pin code is usually done by pressing the corresponding keys. Pressing the key is the way to designate the corresponding number. Other current systems include the designation of the element with a mouse click. In all cases the “object” is selected and perfectly identified. The way the code is subsequently checked is the comparison that the selected objects sequence is identical to the sequences entered the first time, at access code definition. 
         [0037]      FIG. 2A  illustrates a flow chart for a method  200  for creating secure access codes via continuous information in accordance with exemplary embodiments. In exemplary embodiments, when the user is presented with a continuity of objects the simple designation of current systems does not work, since there is little to no chance that the user designate twice exactly the same object, and even less a sequence of presented objects. In exemplary embodiments, to enter the code the first time when the user is presented with a continuum template at block  205 , instead of designating a series of specific objects, the user designated a series of ranges. Each range can include two or more objects that are designated by the user and which constitutes the limits in between the “ideal” object that the user thinks and perceives is within the range that he user has selected. In one embodiment, the user can explicitly indicate those limit objects. In another embodiment, the user can enter the same code several times, and the system determines from these entries a valid range taking into account the variance of the user input. Either way, the system  100  receives the user selection of continuum ranges at block  210 . At block  215 , the system  100  stores the selected ranges for future authentication 
         [0038]      FIG. 2B  illustrates a flowchart for a method  201  for authenticating a user in accordance with exemplary embodiments. In exemplary embodiments, the user can then enter the code for verification when the proposed continuum is presented to the user at block  220 . It is appreciated that the user can enter a code for verification once the access code is first entered similar to current systems in which a user is asked to enter and re-enter a password. It is further appreciated that the following description further applies to each time a user enters the access code. Once the code has been defined as described above, the checking of the code can include the user selecting a sequence of object from the proposed continuum, which the system receives at block  2225 . Then the program verifies that each of the designated object falls into the corresponding range that has been define at access code creation at block  230 . If the program has verified that the designated objects fall within the corresponding range that was stored at block  215 , the user is authenticated at block  235 . However, if the program does not verify that the designated objects fall within the corresponding range that was stored at block  215 , the authentication is rejected at block  240 . In exemplary embodiments, a predetermined number of attempts at authentication can also be stored. At block  245 , the system  100  can check whether or not the predetermined number of attempts has been exceeded at block  245 . If the predetermined number of attempts has been exceeded, then the user is given a failure message at block  250  and the flow ends. If the predetermined number of attempts has not been exceeded at block  245  then the user is presented with the continuum template again at block  220 . 
         [0039]    In exemplary embodiments, the user can also reset the access code. As in many current systems, the simplest way to reset a password is to implement the user mail box for authentication. In exemplary embodiments, when the user is prompted for the access code, the user is also proposed a “reset access code” option (e.g., a button). When the user presses the button a mail is sent to the user&#39;s mail box, which can include a URL. In exemplary embodiments, the URL points to a reset access code program and includes a string identifying the user and a string which has been randomly generated to ensure security. When the URL is accessed, a server program first checks that there is a reset access code request pending for this user and compares the randomly generated string to the one the server stored when the reset button was pressed. If the user is authenticated this way, then the user is offered an “enter a new access code ” like interface. 
       EXAMPLES 
       [0040]    As described above, the system  100  can present a continuum template to the user for entry for the continuous information access code as described herein. For example,  FIG. 3  illustrates a color grid  300  in which objects as described herein are colors. As described herein, the user can select colors and designated ranges from the color grid  300 . 
         [0041]      FIG. 4  illustrates a color bar  400  presented as a rainbow spectrum 
         [0042]    Or in the form of a bar containing the whole rainbow spectrum, 
         [0043]      FIG. 5  illustrates a color grid  500  in accordance with exemplary embodiments. When entering a code, the user selects the range in which the chosen color is positioned. For example, the user selects with a selection device such as a mouse a square  510  in which the color is positioned. 
         [0044]      FIG. 6  illustrates a color bar  600  presented as a rainbow spectrum in accordance with exemplary embodiments. In this example, the user can position two cursors  610 ,  620  to select an indicated range. When the access code is authenticated, the user can click on the chosen color. The program can then check to determine if the designated color is within the defined range as discussed herein. 
         [0045]      FIG. 7  illustrates a target interface  700  in accordance with exemplary embodiments. The interface  700  is in the form of a target. The user can place the selection device in locations on the interface  700  to place “bullet holes”. These designated objects (e.g., the bullet holes) are coordinates of the target (e.g., Cartesian coordinates).  FIG. 8  illustrates a target interface  800  having bullet hole entries  810 . For example, the system  100  can ask the user to enter the same code a series of times. The system  100  then determines variance and standard deviation on x and y axis designation for each element of the series and computes an appropriate range for access code verification range. For code entry for authentication, the user places the “bullet holes”  810  on the target, for example via the mouse (drag and drop). If all bullet holes are within the range defined at access code set-up, then the user is authenticated 
         [0046]    The capabilities of the present invention can be implemented in software, firmware, hardware or some combination thereof. 
         [0047]    As one example, one or more aspects of the present invention can be included in an article of manufacture (e.g., one or more computer program products) having, for instance, computer usable media. The media has embodied therein, for instance, computer readable program code means for providing and facilitating the capabilities of the present invention. The article of manufacture can be included as a part of a computer system or sold separately.
