Contactless Card Login for Secure Account Access on Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices lack secure and efficient methods for users to enter personal information for service provider accounts, leading to errors, security risks, and vulnerabilities in input interfaces.
Innovation Solution
A contactless card is used to generate a cryptogram, which is decrypted by an authentication server to create a virtual account number, enabling secure account creation and automated login to service provider accounts on display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional input interfaces are used on display devices, then users can enter personal information, but security risks increase and errors occur
Solution Approach 1:
The patent introduces a contactless card as an intermediary device between the user and the display device. The card contains an applet that generates a cryptogram, which is then transmitted to an authentication server. This intermediary mechanism eliminates the need for users to directly input sensitive information on the display device, thereby improving security while maintaining ease of operation through a simple tap action.
2Productivity
If manual input of personal information is required, then accounts can be created, but time is lost and errors occur
Solution Approach 1:
The contactless card stores account information and authentication credentials in advance. When the user taps the card on the display device, the pre-stored information is automatically transmitted to create the account or log in, eliminating the need for manual input and multiple attempts. This preliminary preparation of data on the card significantly reduces the time required for account creation and improves productivity.
3Ease of operation
If personal information is displayed on screen during entry, then users can input data, but security risks increase due to visibility
Solution Approach 1:
The patent extracts the sensitive personal information from the display device interface and relocates it to the contactless card. The card handles all data transmission through cryptographic protocols, and no sensitive information is displayed on the screen during the authentication process. This extraction of sensitive data from the vulnerable display interface eliminates security exposure while maintaining ease of operation.

AI summary
Systems, methods, apparatuses, and computer-readable media for secure management of accounts on display devices using a contactless card. An application executing on a display device may receive a request specifying a service provider. The display device may receive a cryptogram generated a contactless card, and transmit the cryptogram to an authentication server. The authentication server may decrypt the cryptogram and generate a virtual account number associated with the contactless card. The authentication server may transmit the virtual account number to the service provider, which may create an account based at least in part on the virtual account number and the decryption of the cryptogram by the authentication server. The display may receive an authentication token generated by the service provider for the account, and access the account created by the service provider based at least in part on the authentication token.
