技術名稱: VLC雙向核銷認證裝置

技術簡介

本技術在消費者端採用智慧手機的螢幕與攝影機作為VLC的資料收發裝置,手機的螢幕可顯示票券內容,並可自動傳送認證碼,攝影機接收核銷裝置的光訊號驗證碼;核銷裝置使用發光元件傳送驗證碼,攝影機接收認證碼後嵌入系統再進行解碼。因此消費者與店家可以在核銷的時候採用攝影機、螢幕及發光元件達到雙向資料交換,提高認證的安全性。

Abstract

This technology uses a smartphone screen and the camera as a VLC consumer data transceiver, the mobile phone screen display the ticket content and authentication code, the mobile phone camera can receive optical signal verification code; the sore verification device using the light-emitting components to send verification code, and the embedded system is decrypted after the camera receives the authentication code. Therefore, consumers and stores in the write-off moment can using the camera, screen and light-emitting components to achieve two-way data exchange, and improve the security of authentication.

技術規格

手機APP 行動票?的尺寸為100*100 pixels,可達106bytes,手機編碼速度需1秒內完成編碼 手機解碼運算速度需達10fps以上 支援iOS 8和Android 4.4 以上作業系統 核銷裝置 可於2秒內解碼完成 當讀取手機上的VLC code時耗電<450mA,待機時耗電<220mA。

Technical Specification

Smartphone APP ~Mobile ticket size of 100 * 100 pixels, up to 106bytes, mobile device encoding speed to be completed within 1 second ~The decoding speed of mobile phone should be over 10fps ~Support iOS 8 and Android 4.4 and above operating system Write-off device ~Decoding time within 2 seconds to be complete ~VLC transmission bit rate at 50bits ~Active power consumption <450mA, standby power consumption <220mA

技術特色

本技術運用可見光通訊(VLC)作為強化核銷安全機制的方法,主要元件為可見光核銷裝置、店端POS機與使用者端之智慧手機。本計畫核銷功能簡述如下,使用者端手機螢幕除了可顯示行動票券內容,同時接收來至核銷裝置之可見光驗證碼。手機APP將可見光驗證碼與票券碼關聯後產生新的合成碼後顯示於手機畫面上,等待核銷裝置讀取合成碼並驗證其正確性,驗證成功後回傳可見光驗證成功碼。
