Multimedia Device One-Time Password Presentation via Audio Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of one-time password technology is hindered by the complexity of distributing hardware devices and the difficulty in modifying existing multimedia devices to generate and display dynamic passwords, which requires significant user interface adjustments and seed storage.
Innovation Solution
A multimedia device is configured to play one-time passwords through multimedia files, such as audio or video files, eliminating the need for seed storage and device modification, allowing for widespread deployment by leveraging its media playback functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional one-time password devices are distributed to users, then secure authentication is achieved, but the logistics of distributing hardware become substantial and complex
Solution Approach 1:
The patent applies universality by enabling existing multimedia devices (MP3 players, video players) to serve dual purposes: their original media playback function and the additional function of generating and displaying one-time passwords. This eliminates the need for separate authentication hardware distribution while maintaining security capabilities.
Solution Approach 2:
The patent uses copying by creating a software implementation of the one-time password generation functionality that replicates the behavior of dedicated hardware tokens. The multimedia device copies the essential function of generating dynamic passwords without requiring physical duplication of specialized authentication hardware.
2Adaptability or versatility
If existing multimedia devices are modified to generate and display one-time passwords, then authentication capability is added, but the user interface becomes complex requiring many clicks to start the application
Solution Approach 1:
The patent merges the one-time password display function with the existing media player interface. The password is presented through the device's native audio or video playback capabilities, combining authentication functionality with the user's existing interaction patterns. This eliminates the need for separate complex authentication interfaces.
Solution Approach 2:
The system automatically generates and presents the one-time password through the multimedia device's existing playback functions without requiring manual configuration or complex user input. The device serves itself by utilizing its built-in audio/video capabilities to deliver authentication information seamlessly.
3Device complexity
If multimedia devices are used for one-time password generation, then device distribution logistics are simplified, but the devices must be preprogrammed with seed information requiring special protocols
Solution Approach 1:
The patent applies preliminary action by pre-programming the multimedia device with a seed value during the manufacturing process. This initial setup enables the device to autonomously generate one-time passwords without requiring field programming or complex setup protocols, simplifying both manufacturing and deployment.
Solution Approach 2:
The system uses parameter changes by transforming the seed value into dynamically changing one-time passwords through cryptographic operations. The seed remains fixed in the device, but the generated passwords continuously change, providing both ease of programming and strong security.
Data Source
AI summary
A multimedia device or other type of processing device comprises a memory, a processor coupled to the memory, and playback circuitry coupled to the processor. In one aspect, the processor is operative to control the storage in the memory of at least one multimedia file containing a one-time password or other type of password, where the password is generated externally to the processing device, and to control the playback of the multimedia file via the playback circuitry to make the password apparent to or otherwise accessible to an associated user or other entity. The multimedia file may comprise, for example, an audio file, with the password being presented to the user in an audible form upon playback of the audio file. As another example, the multimedia file may comprise a video file, with the password being presented to the user in a visible form upon playback of the video file.
