Electronic signature security algorithms

Abstract

Technologies are generally described for security algorithm methods in authorizing and linking devices associated with a customer. A first device can be linked to a customer account. Additional devices can be linked to the customer account. Those devices can be authenticated to perform banking operations using dual factor authentication wherein a customer's login information is a first factor and the customer using a previously authenticated device is a second factor. By using additional methods of authentication, transactions can be done more reliably and securely.

What is claimed is: 
     
         1 . A client device, comprising:
 at least one memory that stores computer executable components; and   a processor that facilitates execution of one or more computer executable components stored within the memory, the computer executable components comprising:
 a display component that displays a user request wherein the display component further receives login information and a banking request from a user based on the user request; 
 a user authentication that authenticates the user based upon sending the login information to a bank server using a communications network; 
 a security component that stores in protected memory a security key associated with the client device wherein the security component further generates an encrypted banking request based on the security key and the banking request; and 
 a bank operation component that sends the encrypted banking request to the bank server using the communications network. 
   
     
     
         2 . The client device of  claim 1 , wherein the bank operation component further receives an encrypted banking operation result. 
     
     
         3 . The client device of  claim 2 , wherein the security component further generates a decrypted banking operation result based on encrypted banking operation result and the security key. 
     
     
         4 . The client device of  claim 3 , wherein the display component further displays the decrypted banking operation result.
