Embodiment Construction

[0013] Smartphones and tablets with larger touchscreens are becoming more common. Users are increasingly familiar with the tactile and intuitive nature of touchscreen interfaces. Gestures such as "two-finger spread", "two-finger pinch", "rotate", "flick" are standardized actions for interacting with multi-touch devices, and usually improve user experience in multiple ways.

[0014] In an embodiment according to the invention, for transactions performed on a mobile handheld terminal, personal computer, tablet or similar device with a touch screen, if the touch screen is controlled by a master secure element with gesture recognition capability, the transaction can be secured safety.

[0015] An exemplary embodiment is described in the above-mentioned related patent application "Secure user authentication using a master secure element", in which the master secure element acts as a secure processor 120 controlling user access to the keypad of a handheld terminal (or touch screen...

Abstract

The present invention provides a method for validating a transaction. The method is applicable to secure transactions on a mobile handset or tablet equipped with a touch screen controlled by a secure processor such as a master secure element or Trusted Execution Environment having gesture recognition capabilities. Since the touch screen is fully controlled by the secure processor, the user can securely enter the transaction amount using gestures to validate the transaction.

Description

technical field [0001] The present invention relates to methods of authenticating transactions, and more particularly to methods of authenticating transactions with secure entry without the need for entry of a PIN code. [0002] US Patent Application (Application No. US 13 / 632,870, Title of Invention: Secure User Authentication Using a Primary Secure Element) filed October 1, 2012 is hereby incorporated by reference in its entirety. [0003] US Patent Application (Application No. US 13 / 632,907, Title of Invention: Verifying Transactions with Secure Inputs and Non-secure Outputs) filed October 1, 2012 is hereby incorporated by reference in its entirety. Background technique [0004] Mobile platforms or connected devices, such as smartphones, PCs and tablets, integrate a secure element to authenticate the platform to protect user credentials or secure transactions. Secure Elements are typically highly tamper-resistant devices that provide a secure execution environment isolat...
