由於網路功能現今已經成為個人電腦必備的功能之一，根據國際電信聯盟(International Telecommunication Union, ITU) 於2011提出的一份統計資料顯示，目前全球網路的使用人口已經突破20億大關，使用者皆可輕易的在網路上下載取得需要的網路資源，只要使用者有使用網路的行為就有遭受Malicious Software攻擊的風險，讓潛伏在網路中的駭客(hacker)有機可趁，植入惡意程式，例如：木馬程式(Trojan horse)、鍵盤側錄程式(Keyboard logger)以及各種惡意間諜程式。這些惡意的攻擊極有可能藉此癱瘓或監控使用者的電腦，導致使用者重要的帳號及密碼資訊外洩，或是使得電腦中機密檔案被竊取的可能性大增。
並且根據ITU的同一份調查資料，統計資料顯示出目前全球使用個人行動裝置(包含個人數位助理(PDA)、行動電話、平板電腦以及智慧型手機等等)。的用戶更是達到了50億的數字，與2000年相比成長的約五倍之多。由於個人行動裝置的處理功能性可比擬小型電腦以及擁有普及化的優點，在本篇論文中，提出一個基於機密資料保護的方法，防止重要檔案被惡意程式破壞以及降低被竊取的風險。
