Abstract
Description
本發明關於一種以複數條碼產生具備完整資訊條碼之系統及方法,特別是指一種將二維條碼分割且分開傳送,再於訊息接收端將條碼片段結合並讀取其內部資訊之系統及方法。The present invention relates to a system and method for generating a complete information barcode using a plurality of barcodes, and more particularly to a system and method for dividing and transmitting a two-dimensional barcode, and then combining the barcode segments at the message receiving end and reading the internal information.
隨著科技日新月異,資訊傳遞不再僅能用文字或數字的方式來表達,目前也可以利用圖片隱藏資訊、條碼等其他方式,供使用者透過電子裝置處理資訊,例如以手機條碼儲存電子發票之「電子發票共通性載具」,消費者可經由特定手機門號的手機條碼及認證碼,手機條碼需印出後可用於儲存電子發票。如此有助於降低資訊呈現量(所需篇幅),且具有便於攜帶及取得等優勢。With the rapid development of technology, information transmission can no longer be expressed by words or numbers. At present, it is also possible to use image hiding information, barcodes and other means for users to process information through electronic devices, such as storing electronic invoices by mobile phone barcodes. "Electronic invoice common vehicle", consumers can use the mobile phone barcode and authentication code of the specific mobile phone number, and the mobile phone barcode can be used to store the electronic invoice after printing. This helps to reduce the amount of information presented (the required length), and has the advantages of being easy to carry and obtain.
對圖片隱藏資訊來說,使用上需透過數學轉換計算才能得到內部所隱藏的資訊,生活中不常見且對於一般使用者而言有使用困難度。對於條碼而言,以往條碼讀取方式多透過條碼讀取機讀取紙本條碼為主,但隨著電子裝置應用日益頻繁,目前已可於行動裝置上使用條碼進行交易或驗證,如提供小額優惠卷之兌換條碼。For image hiding information, the use of mathematical conversion calculations in order to get the information hidden inside, is not common in life and is difficult to use for the average user. For bar codes, the bar code reading method used to read paper bar codes mainly through bar code readers. However, with the increasing frequency of electronic devices, bar codes can be used for transaction or verification on mobile devices, such as providing small amounts. Redemption barcode for coupons.
對於條碼而言,常見的一維條碼以黑、白線條排列而成的圖案,係常見於產品包裝上,用於記載產品的生產國家、製造廠商、生產日期等,亦或者可用於圖書管理上,即以條碼對書籍進行分類或訊息記載,因而條碼在商品、圖書管理、甚至郵政或銀行等皆有廣泛應用。另外,隨著儲存資訊量的增加,更有以二維條碼(QR code)儲存資訊的應用,以黑白兩色的方形圖案呈現,其應用領域廣泛,凡舉農產履歷、政府/商業活動、商品內容、介紹導覽、商業活動折價卷及個人名片等,其內容多為文字顯示或連結至特定網頁讓使用者獲取欲傳遞之資訊,因而被廣泛利用。又如高速鐵路之手機構票系統(T Express),更以目前電子發票載具為例,發證單位可將條碼資訊利用批次網路連線方式傳送至超商的銷售點終端系統(POS),並利用即時網路連線方式送發至消費者的智慧型手機,消費者的智慧型手機可直接取得或產生條碼圖示,消費者即可以此條碼至超商進行交易。For barcodes, the common one-dimensional barcodes are arranged in black and white lines. They are commonly used on product packaging to record the country of manufacture, manufacturer, date of manufacture, etc., or can be used for book management. That is, the classification or record of books by bar code, so the bar code is widely used in commodities, book management, and even postal or banking. In addition, with the increase in the amount of stored information, there are applications that store information in a QR code, which is presented in a square pattern of black and white. It has a wide range of applications, including agricultural history, government/commercial activities, Product content, introduction guides, commercial activity discounts and personal business cards, etc., are mostly used for text display or link to specific web pages for users to obtain information to be transmitted, and thus are widely used. Another example is the high-speed railway hand ticket system (T Express). Taking the current electronic invoice carrier as an example, the issuing unit can transmit the bar code information to the Supermarket's point-of-sale terminal system (POS) by batch network connection. ), and use the instant Internet connection to send the smart phone to the consumer, the consumer's smart phone can directly obtain or generate the bar code icon, the consumer can use this bar code to super-commerce to trade.
隨著二維條碼的應用越來越多及二維條碼使用的普及,對於一般電子條碼掃描即辨識出電子裝置所顯示之訊息或由電子裝置上之條碼進行驗證及交易也越來越頻繁,藉由掃描電子條碼取得資訊愈來愈盛行。然而,目前之技術仍無法限定特定的使用者掃描二維條碼取得其資訊,因為任何人皆能透過手邊的智慧裝置掃描二維條碼取得其資訊,使得以二維條碼無法做為較機密文件、隱私資料的傳輸應用,因此目前二維條碼仍難以進一步深層應用。With the increasing use of two-dimensional bar codes and the popularity of two-dimensional bar codes, it is more and more frequent for the general electronic bar code scanning to recognize the information displayed by the electronic device or to verify and trade the bar code on the electronic device.
