## Background
FILED OF INVENTION
The present invention relates generally to authentication, and more specifically to multifactor authentication through apparatus, systems and methods for identification, in particular, apparatus, systems and methods for identifying an entity for computer and/or network security, secure authorization of a payment or for funds transfer and for selectively granting privileges and providing other services in response to such identifications/authentications.
BACKGROUND
Computer systems typically “authenticate” users prior to allowing access. For example, a desktop computer may authenticate a user with a username and password. When the user provides the correct username and password, the user is “authenticated” and is allowed access to computer resources.
Authentication remains a persistent technical problem in the information technology industry. With the proliferation of untrusted applications and untrusted networks, and the increasing use of the Internet for business functions, the authentication issues have become prominent. Authentication refers to a process by which a user makes his or her identity known to a system or application which the user is attempting to access, and occasionally, also the process by which the user verifies the identity of the system being accessed. A common authentication technique involves the use of a shared username and password combination. This style of authentication is vulnerable to a number of Weaknesses. For example, passwords must be made long enough to be secure while being short enough to be memorable. Additionally, the loss of the password is sufficient to allow an attacker to gain access to the system by impersonating the user. Therefore, additional authentication techniques would find utility.
“Multifactor authentication” generally refers to a security authentication system in which more than one form of authentication is used to validate the identity of a user. For example, a webpage which asks a user to remit a single user name/password combination may be considered a “single-factor” authentication system since it requests a single datum-a username/password combination-in order to validate a user's identity. The webpage may add additional procedures, such as sending a confirmation email to the user's verified email address or matching security code(s) or user device id using Near Field Communication (NFC) tag enabled devices, in order to add additional levels of user authentication, thereby implementing a “multifactor authentication” system for the webpage as well as any computing system.
PRIOR ART
Banks, financial institutions and Social networking websites implement single factor authentication systems for online access to user accounts. In the field of computing, a user may be required to input confidential information on a system for different reasons. In one example, the user may be required to type in a username and password when initially logging into a computer or computer network. In another example, the user may have to manually provide a username and password when logging into certain websites on the system. In yet another example, the user may be required to provide credit card information when shopping online on the system.
In the above examples, the inputting of authentication information can be inconvenient for the user and insecure for the system. Thus, it may be beneficial to lessen user burden and increase system security when authenticating a user on a system. Now a days use system and website is getting personal as well as private to prevent data or access of system from third party or unauthorized user. For such user authentication is required to identify exact user and providing respective access rights to the system or data or websites. Websites such as banking websites or social networking sites requires authentication and login process much more stronger as the data in such a sites is very sensitive and could harm severe side effect such as losing control over user account or misusing the user's personal data. The traditional authentication and login system comprising of username and password having alphanumeric character which is chosen by user itself. In such a process user has to input in the system manually by typing or entering to the system or website. The input is compared with predefined and stored data by user and if matches user is authenticated and allowed to login to system or website. But dumpster diving (getting user credential from dumps or trash), shoulder surfing (watching user while entering credential data) such kinds of attack can crack this security easily and get access to user account information. More so, for multi factor authentication cellular and smart phones can be bulky to carry and it is not always possible to have them readily available to use them as additional authentication level in a multifactor authentication set up. With the advent of mobile internet, mobile phones itself are used as computing device for accessing websites. Thus It is desirable and be convenient to have a device to be secured to a user and easily accessible at all times like a wrist watch. Use of NFC technology in such wrist watches will act as secure and error free user authentication and login in cutting edge age of technology.
From the foregoing it is appreciated that there exists a need for device and method to ameliorate the shortcomings of existing devices and practices used for authentication of users and login to a system or website. Thus there should be multifactor authentication system comprising user input (username and password) as well as user's device id or security code which belongs to user personal device which will be treated as second authenticating factor.

Seeking new device or single authentication mode
The smart wrist watch can be functioned with different modes as follows:
Time Mode:—It would be the default mode in the smart wrist watch, in which mode the date and time will be displayed, the buffer memory would be empty and NFC (Near Field Communication) tag is disabled and is non readable state as such inactive.
NFC Login Mode:—In this mode there are different tag id are pre-loaded in the smart wrist watch. by pressing the mode selection button it can navigate through each tag id and display tag id logo on the screen and the buffer memory is copied with such tag id and will be ready to function as Near Field Communication on tapping the same to the computing device. The NFC Login mode will have default auto locking after 15 seconds and the auto lock counter start decrementing by 1 for every 1 second and NFC login mode will be disabled on completion of 15 seconds and reverts to Time Mode when wrist watch is tapped.
The smart wrist watch which comprises of the scratch proof display having internal non volatile memory with pre defined stored data as tag ids, mode icon in an array format along with the processor to read, write, copy, delete and change mode operations, display mode icon, display date and time. The smart wrist watch also consists of a rechargeable battery and a non volatile memory for storing temporary data along with an operating system to support these various operations.
By default the smart wrist watch will be in Time Mode and pressing the mode button 401 in FIG. 4 the smart wrist watch prompts the user to select the mode. In case user select the NFC Mode, NFC Mode is activated and prompts for selection of Tag id from the array of Tag Id's displayed by relative icon on the smart wrist watch screen, on selecting the tag id the tag id will be copied to the buffer memory and write buffer memory with data in the tag id to NFC tag, if smart wrist watch is tapped to a computing device it makes NFC tag readable and otherwise NFC tag becomes non-readable. On NFC tag becoming readable the auto lock activates and within 15 seconds if the user does not tap for authentication it takes back to the time mode.
During NFC mode activated if the user select particular tag id from the array of tag ids displayed on the smart wrist watch, an icon will be displayed of the tag id selected Ex:—icon of a social networking portal, email icon or other database icon or authentication website icon and the smart Wrist Watch will copy the selected tag id to buffer memory and processor will write buffer memory data that is selected tag id to NFC tag. On tapping of smart Wrist watch to computing device in this mode, NFC tag will be readable to computing device and it will read the selected from NFC tag id and proceed for authentication process of the selected tag id.
