| dc.description.abstract | 點對點串流系統在近年來非常受歡迎且十分普及，由於給個使用者在下載資料同時也提供它的上傳頻寬，使得系統規模能較為彈性。但在是因為在這樣分散式的架構下，容易遭受惡意使用者的攻擊。攻擊者進入系統中，傳送受汙染過的資料，使得整體系統收視品質下降。本論文提出了關於點對點即時串流系統污染問題的防治。我們運用以雜湊函數為基礎，使資料與資料之間有關連性，資料可以互相被驗證，每個使用者可以自行檢驗收到的資料是否正確。另外加上社群網路的協助，擁有相同興趣的朋友會同時在線上收看，利用這層關係，假設從朋友而來的資料是對的，可使我們的系統達到更高的檢測機率，進而快速降低攻擊者所造成的影響。透過模擬實驗的結果，看到我們的方法比起其他現存方法十分有效。 | zh_TW |
