Tactile Binary Coded Communication for Secure Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods are vulnerable to interception by third parties, especially in mobile devices, due to increased mobility and visual limitations, which complicates safeguarding sensitive information.
Innovation Solution
A system and method for surreptitious tactile binary communication using a mobile device, where a processor monitors sequential patterns of user touches to identify encoded messages, converts them into alphanumeric form, and transmits securely, utilizing Morse code for secure and convenient authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication methods (visual displays, verbal communication) are used, then ease of operation is improved, but security against interception deteriorates
Solution Approach 1:
The patent replaces visual and auditory authentication mechanisms with tactile mechanical vibrations. The authentication system uses patterns of vibrations delivered through the mobile device to convey authentication codes and prompts, substituting the traditional visual display and verbal communication with a tactile feedback system that is not susceptible to visual or audio interception.
Solution Approach 2:
The patent introduces tactile vibrations as an intermediary medium for authentication communication. Instead of directly displaying authentication information visually or speaking it verbally, the system encodes authentication data into vibration patterns that are transmitted through the device, creating an intermediate tactile channel that bypasses traditional interception vulnerabilities.
2Ease of operation
If visual displays and verbal communication are used for authentication, then ease of operation is improved, but vulnerability to third-party interception increases
Solution Approach 1:
The patent replaces vulnerable visual and auditory authentication channels with a tactile mechanical vibration system. Authentication codes, prompts, and confirmations are transmitted through patterns of vibrations that can be felt but not seen or heard, eliminating the interception risks associated with visual displays and verbal communication in public or shared environments.
Solution Approach 2:
The patent extracts the authentication information from vulnerable visual and auditory channels and transfers it to a tactile vibration channel. By taking out the authentication data from displays and speakers and encoding it into vibration patterns, the system removes the information from channels that are susceptible to third-party interception while maintaining user accessibility.
3Ease of operation
If font size is increased or information is verbalized for visually limited users, then ease of operation is improved, but interception risk increases
Solution Approach 1:
The patent replaces visual display mechanisms with tactile vibration mechanisms for delivering authentication information to visually limited users. Instead of increasing font size or verbalizing information (which creates interception risks), the system encodes authentication codes and prompts into vibration patterns that provide accessible tactile feedback without exposing sensitive information to visual or auditory interception.

AI summary
Surreptitious communication with a user is disclosed by way of binary tactile inputs and outputs. A communication module of a computing device receives a first alphanumeric message that is converted to a first binary coded message that is rendered as first and second vibration outputs that are humanly distinguishable. A touch input component of one of a touch screen and a motion sensor detects a sequential pattern of user touches. Distinguished first and second tactile inputs in the sequential pattern identify a second binary coded message that is converted into a second alphanumeric message. First and second alphanumeric messages are comprised of a combination of characters selected from one or more of: (i) letters; (ii) numerals; and (iii) symbols.
