社交媒體巨頭聯手遏制網上恐怖主義內容

Facebook, Google, Microsoft and Twitter on Monday announced they had joined forces in an attempt to curb explicit terrorist imagery online.

Facebook、谷歌(Google)、微軟(Microsoft)和Twitter週一宣佈，它們已聯手努力遏制網上帶有明顯恐怖主義色彩的圖像。

The move follows criticism from Brussels that big US social media groups have made insufficient effort to clamp down on hate speech.

此前，歐盟曾批評美國幾大社交媒體公司在遏制仇恨言論方面不夠努力。

In a statement, the technology groups said they were building new technology that would identify extremist content, including terrorist recruitment videos and images of executions, via a digital fingerprint known as a “hash”, which would then be compiled into a shared global database. Once created, the hash would be attached like a watermark to content, which would then be easy to identify and take down.

這些科技公司在一份聲明中表示，它們正在打造新技術，通過一種名爲“散列”(hash)的數字指紋來識別極端主義內容，包括恐怖分子招募視頻和處決圖片，這些數字指紋將被彙集至一個共享的全球數據庫。散列一經創建，將像水印一樣附着在內容上，令這些內容易於被識別和刪除。

“Our companies will begin sharing hashes of the most extreme and egregious terrorist images and videos we have removed from our services,” the companies said. “By sharing this information with each other, we may use the shared hashes to help identify potential terrorist content on our respective hosted consumer platforms.”

這些公司稱：“我們將開始共享已從我們的服務中刪除的那些最極端、最惡劣的恐怖主義圖片和視頻的散列。通過彼此分享這一信息，我們可以利用共享的散列來幫助識別我們各自的託管消費者平臺上的潛在恐怖主義內容。”

The project will be presented at the EU Internet Forum on Thursday, with the database launching in early 2017.

該計劃將於週四在歐盟互聯網論壇(EU Internet Forum)上公佈，相關數據庫將於2017年初推出。

Facebook and Twitter insist the new hash database will not act as a generalised censorship tool but instead assist human users in flagging the most egregious content.

Facebook和Twitter堅稱，新的散列數據庫不會被用作泛泛的審查工具，而是用來幫助人類用戶標識最惡劣的內容。
