有效的連續數字辨識機制及其應用在身分證字號的實現

Abstract

在個人資訊安全防護的領域，偵測訊息洩漏一直是一個重要的研究題材。這篇論文裡，提出了一種簡單且有效率的方案，這個方案的功效在於能快速偵測出某些敏感資料的一項共同特徵— 具有連續的數字串列，這些敏感資料有個人身分證字號、電話號碼、銀行帳戶、駕照編號和信用卡卡號等。這個方案包含了一個預過濾器和一組驗證模組。在實際應用方面，我們將此方案應用在偵測台灣發行的個人身分證字號上且假設是在ASCII 編碼環境下操作。模擬結果顯示，應用此方案相較於直接的做法，能使整個系統效能有顯著的改善。

Detection of information leak has become an important research subject in the area of information security. In this thesis, we propose a simple, efficient scheme to detect consecutive numbers, a common feature of some sensitive data such as personal identification (PID), phone number, bank account, driver license, credit card, and so on. This scheme consists of a pre-filter and a verification module. As an example, we apply the proposed scheme to detection of PID issued by Taiwan government. We assume that the PID is ASCII encoded. Results show that our proposed scheme improves system performance significantly, as compared with the straightforward implementation.
